Igor Minar f16150d5f1 docs(*): simplify doc urls
we now have two types of namespaces:

- true namespace: angular.* - used for all global apis
- virtual namespace: ng.*, ngMock.*, ... - used for all DI modules

the virual namespaces have services under the second namespace level (e.g. ng.)
and filters and directives prefixed with filter: and directive: respectively
(e.g. ng.filter:orderBy, ng.directive:ngRepeat)

this simplifies urls and makes them a lot shorter while still avoiding name collisions

Misko Hevery c3a41ff9fe feat($compile): simplify isolate scope bindings
Changed the isolate scope binding options to:
  - @attr - attribute binding (including interpolation)
  - =model - by-directional model binding
  - &expr - expression execution binding

This change simplifies the terminology as well as
number of choices available to the developer. It
also supports local name aliasing from the parent.

BREAKING CHANGE: isolate scope bindings definition has changed and
the inject option for the directive controller injection was removed.

To migrate the code follow the example below:

Before:

scope: {
  myAttr: 'attribute',
  myBind: 'bind',
  myExpression: 'expression',
  myEval: 'evaluate',
  myAccessor: 'accessor'
}

After:

scope: {
  myAttr: '@',
  myBind: '@',
  myExpression: '&',
  // myEval - usually not useful, but in cases where the expression is assignable, you can use '='
  myAccessor: '=' // in directive's template change myAccessor() to myAccessor
}

The removed `inject` wasn't generaly useful for directives so there should be no code using it.

Misko Hevery 9be82d942f refactor($compile): always call attr.$observe
attr.$observe used to call function only if there was interpolation
on that attribute. We now call the observation function all the time
but we only save the reference to it if interpolation is present.

Max 1d388676e3 fix(ngRepeat): expose $first, $middle and $last instead of $position
$position marker doesn't work well in cases when we have just one item
in the list because then the item is both the first and last. To solve
this properly we need to expose individual $first and $middle and $last
flags.

BREAKING CHANGE: $position is not exposed in repeater scopes any more

To update, search for $position and replace it with one of $first,
$middle or $last.

Misko Hevery ec1c5dfaee fix(jqLite): .data()/.bind() memory leak
Since angular attaches scope/injector/controller
into DOM it should clean up after itself. No need
to complain about memory leaks, since they can
only happened on detached DOM. Detached DOM would
only be in tests, since in production the DOM
would be attached to render tree and removal
would automatically clear memory.

Misko Hevery 24e7da4f19 fix(angular-mocks): memory leak in jasmine's DI utils

Igor Minar c1533ef576 fix($location): support urls with any protocol

Igor Minar 679cb8a74a fix($browser/$location): single quote in url causes infinite digest in FF
The real issue is in FF, see https://bugzilla.mozilla.org/show_bug.cgi?id=407172.

FF overly encodes stuff which breaks our expectations and then we fail .url() != currentUrl.absUrl()
comparison unexpectidly, which leads to infinite digest.

The workaround is to correct for this inconsistency in $browser and decode any single quotes in urls.

Igor Minar 2b87c814ab feat($parse): CSP compatibility
CSP (content security policy) forbids apps to use eval or
Function(string) generated functions (among other things). For us to be
compatible, we just need to implement the "getterFn" in $parse without
violating any of these restrictions.

We currently use Function(string) generated functions as a speed
optimization. With this change, it will be possible to opt into the CSP
compatible mode using the ngCsp directive. When this mode is on Angular
will evaluate all expressions up to 30% slower than in non-CSP mode, but
no security violations will be raised.

the application. For example:

Igor Minar 6d7e7fdea6 fix($location): properly rewrite urls in html5 mode with base url set
previously we were doing all kinds of checks to see if we should rewrite the url or not and we
were missing many scenarios. not any more.

with this change, we rewrite the url unless:
- the href is not set
- link has target attribute
- the absolute url of the link doesn't match the absolute prefix for all urls in our app

This also means that ng-ext-link attribute which we previously used to distinguish external
links from app links is not necessary any more. apps can just set target=_self to prevent
rewriting.

BREAKING CHANGE: ng-ext-link directive was removed because it's unnecessary

apps that relied on ng-ext-link should simply replace it with target=_self

Igor Minar dceafd32ee feat($http): expose the defaults config as $http.defaults
Often it is impossible to set the http defaults during the config phase,
because the config info is not available at this time.

A good example is authentication - often the app needs to bootstrap,
allow user to enter credentials and only then it gains access to
session token which then should be sent to the server with every request.
Without having the ability to set the defaults at runtime, the developer
either has to resort to hacks, or has to set the session token header
with every request made by the app.

Vojta Jina 5f70d615a5 refactor(ngInclude): remove scope attribute
The purpose of allowing the scope to be specified was to enable the $route service to work
together with ngInclude. However the functionality of creating scopes was in the recent past
moved from the $route service to the ngView directive, so currently there is no valid use case
for specifying the scope for ngInclude. In fact, allowing the scope to be defined can under
certain circumstances lead to memory leaks.

Breaks ngInclude does not have scope attribute anymore.

Vojta Jina 06d0955074 feat(ngModel): update model on each key stroke (revert ngModelInstant)
It turns out that listening only on "blur" event is not sufficient in many scenarios,
especially when you use form validation you always had to use ngModelnstant
e.g. if you want to disable a button based on valid/invalid form.

The feedback we got from our apps as well as external apps is that the
ngModelInstant should be the default.

In the future we might provide alternative ways of suppressing updates
on each key stroke, but it's not going to be the default behavior.

Apps already using the ngModelInstant can safely remove it from their
templates. Input fields without ngModelInstant directive will start propagating
the input changes into the model on each key stroke.

Igor Minar aaedefb92e refactor($sniffer): make $sniffer service private
This service has been accidentaly documented in the past, it should not be considered
to be public api.

I'm also removing fallback to Modernizr since we don't need it.

Breaks any app that depends on this service and its fallback to Modernizr, please
migrate to custom "Modernizr" service:

    module.value('Modernizr', function() { return Modernizr; });

caused all of the scripts to be reloaded.

Vojta Jina 1084ccf7ef fix(docs): Add $locationProvider methods to the docs example provider
- $locationProvider.html5Mode

Docs example is basically a different application on the same page, but we don't want to instantiate multiple instances of $browser or $location service, so we are overriding these providers to return the instances from parent app.

Overriding the service with $provide.value caused a provider to be auto-generated without the necessary hashPrefix and html5Mode apis.

Vojta Jina 60743fc52a feat(ng:include) Fire $contentLoaded event
+ refactor unload to listen on this event -> we can use unload with ng:view as well

Closes #743
2012-02-28 17:48:07 -08:00
Vojta Jina 9486590e1b refactor(ng:view) Make $route scope agnostic, add $contentLoaded event
Problems:

- controller was instantiated immediately on $afterRouteChange (even if no content), that's
different compare to ng:controller, which instantiates controllers after compiling
- route listened on current scope ($afterRouteChange), so if you were listening on $rootScope
($afterRouteChange), you get called first and current.scope === undefined, which is flaky
- route handles scope destroying, but scope is created by ng:view
- route fires after/before route change even if there is no route (when no otherwise specified)

Solution:

- route has no idea about scope, whole scope business moved to ng:view (creating/destroying)
- scope is created (and controller instantiated) AFTER compiling the content
- that means on $afterRouteChange - there is no scope yet (current.scope === undefined)
- added $contentLoaded event fired by ng:view, after linking the content

jQuery.ajax() does request to current url, if url is not specified, so I decided for this solution.

Igor Minar a13b5ed3bc fix($http): fix and cleanup $http and friends
$http:
- use promises internally
- get rid of XhrFuture that was previously used internally
- get rid of $browser.defer calls for async stuff (serving from cache),
  promises will take care of asynchronicity
- fix transformation bugs (when caching requested + multiple request
  pending + error is returned)
- get rid of native header parsing and instead just lazily parse the
  header string

$httpBackend:
- don't return raw/mock XMLHttpRequest object (we don't use it for
  anything anymore)
- call the callback with response headers string

mock $httpBackend:
- unify response api for expect and when
- call the callback with response headers string
- changed the expect/when failure error message so that EXPECTED and GOT
  values are aligned

IE8 and older don't support this events and IE9 has a problematic

and users might end up getting the content for the previous include rendered instead of the most
recent one.

Codier 29f9e2665d fix(scope): $watch (and angular.equals) should support NaN values
- since NaN !== NaN in javascript digest can get into an infinite loop
  when model value is set to NaN
- angular.equals(NaN, NaN) should return true since that's what we
  expect when comparing primitives or objects containing NaN values

Previously NaN because of its special === properties was used as the
initial value for watches, but that results in issues when NaN is used
as model value.

In order to allow for model to be anything incuding undefined and NaN we
need to mark the initial value differently in a way that would avoid
these issues, allow us to run digest without major perf penalties and
allow for clients to determine if the listener is being called because
the watcher is being initialized or because the model changed. This
implementation covers all of these scenarios.

BREAKING CHANGE: previously to detect if the listener was called because
the watcher was being initialized, it was suggested that clients check
if old value is NaN. With this change, the check should be if the newVal
equals the oldVal.

Igor Minar 3945f884c5 fix(ng:repeat) with array ignore properties not representing array elements
Along the way I also changed the repeater impl to use for loop instead
of for in loop.

Iteration over objects is handled by creating an array of keys, which is
sorted and this array then determines the order of iteration over an
element. This makes repeating over objects deterministic and
cross-browser compatible.

Igor Minar f38010d3a2 fix(compiler): revert 8611ebe6 - calling \$digest after linking
Change introduced by me in 8611ebe6 results in considerable inefficiencies when the compiler
and linker is used from within a widget, in which case, we call $digest unnecessary since it
will be called by the $apply which called the directive/widget in the first place.

There are only two places when the extra $digest call can be useful - when manually bootstrapping
the app or in tests. However even in tests this behavior can result in unwanted results (especially
when ng:controller is involved). So it is better to leave it for the developer to call $digest
when it is really needed.

# Things to notice
* Routes are defined in the `AppCntl` class. The initialization of the controller causes the
initialization of the {@link api/angular.service.$route $route} service with the proper URL
routes.
* The {@link api/angular.service.$route $route} service then watches the URL and instantiates the
initialization of the {@link api/ng.$route $route} service with the proper URL
routes.
* The {@link api/ng.$route $route} service then watches the URL and instantiates the
appropriate controller when the URL changes.
* The {@link api/angular.widget.ng:view ng:view} widget loads the view when the URL changes. It
also
sets the view scope to the newly instantiated controller.
* The {@link api/ng.directive:ngView ngView} widget loads the
view when the URL changes. It also sets the view scope to the newly instantiated controller.
* Changing the URL is sufficient to change the controller and view. It makes no difference whether
the URL is changed programatically or by the user.

# Overview
This page explains the Angular initialization process and how you can manually initialize Angular
if necessary.
# Angular `<script>` Tag
This example shows the recommended path for integrating Angular with what we call automatic
initialization.
<pre>
<!doctype html>
<html xmlns:ng="http://angularjs.org" ng-app>
<body>
...
<script src="angular.js">
</body>
</html>
</pre>
* Place the `script` tag at the buttom of the page. Placing script tags at the end of the page
impreves app load time becouse the HTML loading is not blocked by loading of the `angular.js`
script. You can get the latest bits from {@link http://code.angularjs.org}. Please don't link
your production code to this URL, as it will expose a security hole on your site. For
experimental development linking to our site is fine.
* Choose: `angular-[version].js` for a human-readable file, suitable for development and
debugging.
* Choose: `angular-[version].min.js` for a compressed and obfuscated file, suitable for use in
production.
* Place `ng-app` to the root of your application, typically on the `<html>` tag if you want
anugular to auto-bootstrap your application.
<html ng-app>
* If you chose to use the old style directive syntax `ng:` then include xml-namespace in `html`
to make IE happy. (This is here for historical resons, and we no longer recomend use of
`ng:`.)
<html xmlns:ng="http://angularjs.org">
# Automatic Initialization
Angular initializes automatically upon `DOMContentLoaded` event, at which point angular looks for
the {@link api/ng.directive:ngApp `ng-app`} directive which
designates your application root. If {@link
api/ng.directive:ngApp `ng-app`} directive is found then Angular
will:
* load the {@link guide/module module} associated with the directive.
* create the application {@link api/AUTO.$injector injector}
* compile the DOM treating the {@link api/ng.directive:ngApp
`ng-app`} directive as the root of the compilation. This allows you to tell it to treat only a
portion of the DOM as an Angular application.

<html ng-app="optionalModuleName">
<body>
I can add: {{ 1+2 }}.
<script src="angular.js"></script>
</body>
</html>
</pre>
# Manual Initialization
If you need to have more control over the initialization process, you can use a manual
bootstrapping method instead. Examples of when you'd need to do this include using script loaders
or the need to perform an operation before the Angular compiles a page.
Here is an example of manually initializing Angular. The example is equivalent to using the {@link
api/ng.directive:ngApp ng-app} directive.
<pre>
<!doctype html>
<html xmlns:ng="http://angularjs.org">
<body>

<script src="http://code.angularjs.org/angular.js"></script>
<script>
angular.element(document).ready(function() {
angular.bootstrap(document);
});
</script>
</body>
</html>
</pre>
This sequence that your code should follow:
1. After the page and all of the code is loaded, find the root of the HTML template, which is
typically the root of the document.
2. Call {@link api/angular.bootstrap} to {@link compiler compile} the template into an
executable, bi-directionally bound application.

@ngdoc overview
@name Developer Guide: HTML Compiler
@description
# Overview
Angular's {@link api/ng.$compile HTML compiler} allows the developer to teach the
browser new HTML syntax. The compiler allows you to attach behavior to any HTML element or attribute
and even create new HTML element or attributes with custom behavior. Angular calls these behavior
extensions {@link api/ng.$compileProvider.directive directives}.
HTML has a lot of constructs for formatting the HTML for static documents in declarative fashion.
For example if something needs to be centered, there is no need to provide instructions to the
browser how the window size needs to be divided in half so that center is found, and that this
center needs to be aligned with the text's center. Simply add `align="center"` attribute to any
element to achieve the desired behavior. Such is the power of declarative language.
But the declarative language is also limited, since it does not allow you to teach the browser new
syntax. For example there is no easy way to get the browser to align the text at 1/3 the position
instead of 1/2. What is needed is a way to teach browser new HTML syntax.
Angular comes pre-bundled with common directives which are useful for building any app. We also
expect that you will create directives that are specific to your app. These extension become a
Domain Specific Language for building your application.
All of this compilation takes place in the web browser; no server side or pre-compilation step is
involved.
# Compiler
Compiler is an angular service which traverses the DOM looking for attributes. The compilation
process happens into two phases.
1. **Compile:** traverse the DOM and collect all of the directives. The result is a linking
function.
2. **Link:** combine the directives with a scope and produce a live view. Any changes in the
scope model are reflected in the view, and any user interactions with the view are reflected
in the scope model. Making the scope model a single source of truth.
Some directives such {@link api/ng.directive:ngRepeat
`ng-repeat`} clone DOM elements once for each item in collection. Having a compile and link phase
improves performance since the cloned template only needs to be compiled once, and then linked
once for each clone instance.
# Directive
Directive is a behavior which should be triggered when specific HTML constructs are encountered in
compilation process. The directives can be placed in element names, attributes, class names, as
well as comments. Here are some equivalent examples of invoking {@link
api/ng.directive:ngBind `ng-bind`} directive.
<pre>
<span ng-bind="exp"></span>
<span class="ng-bind: exp;"></span>
<ng-bind></ng-bind>
<!-- directive: ng-bind exp -->
</pre>
Directive is just a function which executes when the compiler encounters it in the DOM. See {@link
api/ng.$compileProvider.directive directive API} for in depth documentation on how
to write directives.
Here is a directive which makes any element draggable. Notice the `draggable` attribute on the
`<span>` element.
<example module="drag">
<file name="script.js">
angular.module('drag', []).
directive('draggable', function($document) {
var startX=0, startY=0, x = 0, y = 0;
return function(scope, element, attr) {
element.css({
position: 'relative',
border: '1px solid red',
backgroundColor: 'lightgrey',
cursor: 'pointer'
});
element.bind('mousedown', function(event) {
startX = event.screenX - x;
startY = event.screenY - y;
$document.bind('mousemove', mousemove);
$document.bind('mouseup', mouseup);
});
function mousemove(event) {
y = event.screenY - startY;
x = event.screenX - startX;
element.css({
top: y + 'px',
left: x + 'px'
});
}
function mouseup() {
$document.unbind('mousemove', mousemove);
$document.unbind('mouseup', mouseup);
}
}
});
</file>
<file name="index.html">
<span draggable>Drag ME</span>
</file>
</file>
The presence of `draggable` attribute an any element gives the element new behavior. The beauty of
this approach is that we have thought the browser a new trick, we have extended the vocabulary of
what browser understands in a way, which is natural to anyone who is familiar with HTML
principles.
# Understanding View
There are many templating systems out there. Most of them consume a static string template and
combine it with data, resulting in a new string. The resulting text is then `innerHTML`ed into
an element.
<img src="img/One_Way_Data_Binding.png">
This means that any changes to the data, need to be re-merged with the template and then
`innerHTML`ed into the DOM. Some of the issues are: reading user input and merging it with data,
clobbering user input by overwriting it, managing the whole update process, and lack of behavior
expressiveness.
Angular is different. Angular compiler consumes DOM with directives, not string templates. The
result is a linking function, which when combined with a scope model results in live view. The
view and scope model bindings are transparent, no action from the developer is needed to update
the view. And because no `innerHTML` is used there are no issues of clobbering user input.
Furthermore, angular directives can contain not just text bindings, but behavioral constructs as
well.
<img src="img/Two_Way_Data_Binding.png">
The Angular approach produces stable DOM. This means that the DOM element instance bound to model
item instance does not change for the lifetime of the binding. This means that the code can get
hold of the elements and register event handlers and know that the reference will not be destroyed
by template data merge.

@ngdoc overview
@name Developer Guide: Initializing Angular: Automatic Initiialization
@description
Angular initializes automatically when you load the angular script into your page, specifying
angular's `ng:autobind` attribute with no arguments:
<script src="angular.js" ng:autobind>
From a high-level view, this is what happens during angular's automatic initialization process:
1. The browser loads the page, and then runs the angular script.
The `ng:autobind` attribute tells angular to compile and manage the whole HTML document. The
compilation phase is initiated in the page's `onLoad()` handler. Angular doesn't begin processing
the page until after the page load is complete.
2. Angular finds the root of the HTML document and creates the global variable `angular` in the
global namespace. Everything that angular subsequently creates is bound to fields in this global
object.
3. Angular walks the DOM looking for angular widgets, directives, and markup (such as `ng:init` or
`ng:repeat`). As angular encounters these, it creates child scopes as necessary and attaches them
to the DOM, registers listeners on those scopes, associates any controller functions with their
data and their part of the view, and ultimately constructs a runnable application. The resulting
app features two-way data-binding and a nice separation between data, presentation, and business
logic.
4. For the duration of the application session (while the page is loaded), angular monitors the
state of the application, and updates the view and the data model whenever the state of either one
changes.
For details on how the compiler works, see {@link dev_guide.compiler Angular HTML Compiler}.
## Initialization Options
The reason why `ng:autobind` exists is because angular should not assume that the entire HTML
document should be processed just because the `angular.js` script is included. In order to compile
only a part of the document, specify the ID of the element you want to use for angular's root
element as the value of the `ng:autobind` attribute:
ng:autobind="angularContent"
## Auto-bootstrap with `#autobind`
In some rare cases you can't define the `ng:` prefix before the script tag's attribute (for
example, in some CMS systems). In those situations it is possible to auto-bootstrap angular by
appending `#autobind` to the `<script src=...>` URL, like in this snippet:
<pre>
<!doctype html>
<html>
<head>
<script type="text/javascript"
src="http://code.angularjs.org/angular.js#autobind"></script>
</head>
<body>
<div xmlns:ng="http://angularjs.org">
Hello {{'world'}}!
</div>
</body>
</html>
</pre>
As with `ng:autobind`, you can specify an element id that should be exclusively targeted for
compilation as the value of the `#autobind`, for example: `#autobind=angularContent`.
## Filename Restrictions for Auto-bootstrap
In order for us to find the auto-bootstrap from a script attribute or URL fragment, the value of
the `script` `src` attribute that loads the angular script must match one of these naming
conventions:
- `angular.js`
- `angular-min.js`
- `angular-x.x.x.js`
- `angular-x.x.x.min.js`
- `angular-x.x.x-xxxxxxxx.js` (dev snapshot)
- `angular-x.x.x-xxxxxxxx.min.js` (dev snapshot)
- `angular-bootstrap.js` (used for development of angular)
Optionally, any of the filename formats above can be prepended with a relative or absolute URL that
ends with `/`.
## Global Angular Object
The angular script creates a single global variable `angular` in the global namespace. All angular
APIs are bound to fields of this global object.

Letting angular handle the initialization process (bootstrapping) is a handy way to start using
angular, but advanced users who want more control over the initialization process can choose to use
the manual bootstrapping method instead.
The best way to get started with manual bootstrapping is to look at the what happens when you use
{@link api/angular.directive.ng:autobind ng:autobind}, by showing each step of the process
explicitly.

This is the sequence that your code should follow if you bootstrap angular on your own:

the document.
2. Run angular's {@link dev_guide.compiler Angular HTML compiler}, which converts a template into

@name Developer Guide: Initializing Angular
@description
Initializing angular consists of loading the `angular.js` script in your page, and specifying how
angular should process and manage the page. To initialize angular you do the following:
* Specify the angular namespace in the `<html>` page
* Choose which flavor of angular script to load (debug or production)
* Specify whether or not angular should process and manage the page automatically (`ng:autobind`)
The simplest way to initialize angular is to load the angular script and tell angular to compile
and manage the whole page. You do this as follows:
<pre>
<!doctype html>
<html xmlns:ng="http://angularjs.org">
<head>
...
</head>
<body>
...
<script src="angular.js" ng:autobind>
</body>
</pre>
## Specifying the Angular Namespace
<html xmlns:ng="http://angularjs.org">
You need to declare the angular namespace declaration in the following cases:
* For all types of browser if you are using XHTML.
* For Internet Explorer older than version 9 (because older versions of IE do not render widgets
properly for either HTML or XHTML).
## Creating Your Own Namespaces
When you are ready to define your own {@link dev_guide.compiler.widgets widgets}, you must create
your own namespace in addition to specifying the angular namespace. You use your own namespace to
form the fully qualified name for widgets that you create.
For example, you could map the alias `my` to your domain, and create a widget called `my:widget`.
To create your own namespace, simply add another `xmlns` tag to your page, create an alias, and set
it to your unique domain:
<html xmlns:ng="http://angularjs.org" xmlns:my="http://mydomain.com">
## Loading the Angular Bootstrap Script
The angular bootstrap script comes in two flavors; a debug script, and a production script:
* angular-[version].js - This is a human-readable file, suitable for development and debugging.
* angular-[version].min.js - This is a compressed and obfuscated file, suitable for use in
production.

@description
An angular directive is a custom HTML attribute that angular knows how to process. You add them to
a template element like any other attribute. Angular directives all have a `ng:` prefix. In the
following example, the angular directive (`ng:controller`) is a div tag:
<div ng:controller>
You use angular directives to modify DOM element properties. The element you modify can be an
existing HTML element type or a custom DOM element type that you created. You can use any number of
directives per element.
You add angular directives to a standard HTML tag as in the following example, in which we have
added the {@link api/angular.directive.ng:click ng:click} directive to a button tag:
<button name="button1" ng:click="foo()">Click This</button>
In the example above, `name` is the standard HTML attribute, and `ng:click` is the angular
directive. The `ng:click` directive lets you implement custom behavior in an associated controller
function.
In the next example, we add the {@link api/angular.directive.ng:bind ng:bind} directive to a
`<span>` tag:
<span ng:bind="1+2"></span>
The `ng:bind` directive tells angular to set up {@link dev_guide.templates.databinding data
binding} between the data model and the view for the specified expression. When the angular {@link
dev_guide.compiler compiler} encounters an `ng:bind` directive in a template, it passes the
attribute value to the `ng:bind` function, which in turn sets up the data binding. On any change to
the expression in the model, the view is updated to display the span text with the changed
expression value.

@name Developer Guide: Angular HTML Compiler: Comparing Directives and Attribute Widgets
@description
Although directives and {@link dev_guide.compiler.widgets attribute widgets} appear the same in a
template (`ng:init` is a directive, `ng:repeat` is an attribute widget), there is a difference in
the order in which they are evaluated. The user of existing directives or widgets cannot determine
the order of evaluation. The evaluation order is the responsibility of the developer creating
custom directives and widgets.
For example, consider this piece of HTML, which uses the `ng:repeat`, `ng:init`, and `ng:bind`
widget and directives:
<pre>
<ul ng:init="people=['mike', 'mary']">
<li ng:repeat="person in people"
ng:init="a=a+1"
ng:bind="person">
</li>
</ul>
</pre>
Notice that the order of execution matters here. Because we want to run the `ng:init="a=a+1` and
`ng:bind="person"` once for each `person in people`, we need to execute {@link
api/angular.widget.@ng:repeat ng:repeat} to make copies of the `<li>` element before we run the
{@link api/angular.directive.ng:init ng:init}, and {@link api/angular.directive.ng:bind ng:bind}
for each of the `<li>`copies.
If you implemented `ng:repeat` as a directive, there would be no guarantee that the attributes
`ng:repeat`, `ng:init`, and `ng:bind` would be evaluated in the order they are declared, because
the order of element attributes in HTML is not significant to the browser.
So, when creating a custom HTML attribute, you will have to consider whether a directive or a
widget is more appropriate. When the order of execution doesn't matter, directives are the right
choice. In a situation where the order matters and one attribute should be processed with a higher
priority than others, use a widget for the attribute that must be processed first.

# Compilation process for `<my:greeter>`
Here are the steps that the compiler takes in processing the page that contains the widget
definition above:
## Compile Phase
1. Recursively traverse the DOM depth-first.
2. Find the angular.widget definition.
3. Find and execute the widget's compileElement function, which includes the following steps:
1. Add a style element with attribute display: block; to the template DOM so that the browser
knows to treat the element as block element for rendering. (Note: because this style element was
added on the template compileElement, this style is automatically applied to any clones of the
template (i.e. any repeating elements)).
2. Extract the salutation and name HTML attributes as angular expressions.
4. Return the aggregate link function, which includes just one link function in this example.
## Link Phase
1. Execute the aggregate link function, which includes the following steps:
1. Create a <span> element set to the salutation class
2. Create a <span> element set to the name class.
2. Add the span elements to the linkElement. (Note: be careful not to add them to the
compileElement, because that's the template.)
3. Set up watches on the expressions. When an expression changes, copy the data to the
corresponding spans.

@name Developer Guide: Angular HTML Compiler: Understanding Angular Markup
@description
Markup in angular is a feature that you can use in templates to transform the content of DOM
elements prior to the compile phase (in which elements are compiled and link functions are
returned. See the {@link dev_guide.compiler compiler docs} for details on how the compiler
works.) The ability to make pre-compile changes to DOM elements lets you create shorthand for
{@link api/angular.widget widget} and {@link api/angular.directive directive} declarations.
Angular provides one built-in markup feature: the double curly-braces used to declare binding
points (between the model and view) for angular expressions. You can also create your own custom
markup.
# Using Double Curly-brace Markup (`{{ }}`)
The double curly-brace (`{{ }}`) markup translates an enclosed expression into an {@link
api/angular.directive.ng:bind ng:bind} directive:
<pre>
{{expression}}
</pre>
is transformed to:
<pre>
<span ng:bind="expression"></span>
</pre>
Markup is useful for the simple reason that `{{1+2}}` is easier to write and understand than `<span
ng:bind="1+2"></span>`. After markup shorthand is expanded into the DOM elements it represents, the
expanded elements are then {@link dev_guide.compiler compiled} normally.
# Creating Custom Markup
Let's say you want to define markup that transforms `---` into a horizontal rule (`<hr/>`):
<pre>
header
---
footer
</pre>
should translate to:
<pre>
header
<hr/>
footer
</pre>
Here is how you could extend the angular compiler to create the "---" markup:
<pre>
angular.markup('---', function(text, textNode, parentElement) {
var compiler = this;
var index = text.indexOf('---');
if (index > -1) {
textNode.after(text.substring(index + 3));
textNode.after(angular.element('<hr>'));
textNode.after(text.substring(0, index));
textNode.remove();
}
});
</pre>
Unlike the way the compiler processes {@link api/angular.widget widgets} and {@link
api/angular.directive directives} (matching the name of the handler function to a DOM element or
attribute name), the compiler calls every markup handler for every text node, giving the handler a
chance to transform the text. The markup handler needs to find all the matches in the text.
## Attribute Markup
Attribute markup extends the angular compiler in a very similar way to markup, except that it
allows you to modify the state of attribute text rather then the content of a node.
<pre>
angular.attrMarkup('extraClass', function(attrValue, attrName, element){
if (attrName == 'additional-class') {
element.addClass(attrValue);
}
});
</pre>

The core of angular is its HTML compiler. The compiler processes angular directives, widgets, and
markup to transform a static HTML page into a dynamic web application.
The default HTML transformations that the angular compiler provides are useful for building generic
apps, but you can also extend the compiler to create a domain-specific language for building
specific types of web applications.
All compilation takes place in the web browser; no server is involved.

@ngdoc overview
@name Developer Guide: Angular HTML Compiler: Understanding How the Compiler Works
@description
Every {@link api/angular.widget widget}, {@link api/angular.directive directive} and {@link
dev_guide.compiler.markup markup} is defined with a compile function, which the angular compiler
executes on each widget or directive it encounters. The compile function optionally returns a link
function. This compilation process happens automatically when the page is loaded when you specify
`ng:autobind` in the script tag from which you load the angular script file. (See {@link
dev_guide.bootstrap Initializing Angular}.)
The compile and link functions are related as follows:
* **compile function** — Registers a listener for the widget, directive, or markup expression. The
compiler calls this function exactly once.
* **link function** — Sets up the listener registered by the compile function. This function can be
called multiple times, once per cloned DOM element. For example, in the case of the {@link
api/angular.widget.@ng:repeat repeater widget} used in a list element (`<li ng:repeat="[item in
dataset]"`), the link function gets called to set up a listener on each element in the list.
Note that angular's built-in widgets, directives, and markup have predefined compile and link
functions that you don't need to modify. When you create your own widgets, directives, or markup,
you must write compile and link functions for them. Refer to the {@link api/angular.compile
Compiler API} for details.
When the angular compiler compiles a page, it proceeds through 3 phases: Compile, Create Root
Scope, and Link:
1. Compile Phase
1. Recursively traverse the DOM, depth-first.
2. Look for a matching compile function of type widget, then markup, then directive.
3. If a compile function is found then execute it.
4. When the compile function completes, it should return a link function. Aggregate this link
function with all link functions returned previously by step 3.
5. Repeat steps 3 and 4 for all compile functions found.
The result of the compilation phase is an aggregate link function, which comprises all of the
individual link functions.
2. Create Root Scope Phase
* Inject all services into the root scope.
3. Link Phase
1. Execute the aggregate link function with the root scope. The aggregate link function calls
all of the individual link functions that were generated in the compile phase.
2. If there are any clones of the DOM caused by repeating elements, call the link function
multiple times, one for each repeating item.
Note that while the compile function is executed exactly once, the link function can be executed
multiple times, for example, once for each iteration in a repeater.
The angular compiler exposes methods that you will need to make use of when writing your own
widgets and directives. For information on these methods, see the {@link api/angular.compile
Compiler API doc}.

@description
When you create your own widgets, you must set up your own namespace for them. (See
dev_guide.bootstrap Initializing Angular} for information about namespaces in angular.)
Let's say we would like to create a new element type in the namespace `my` that can watch an
expression and `alert()` the user with each new value:
<pre>
// An element widget
<my:watch exp="name"></my:watch>
</pre>
You can implement `my:watch` like this:
<pre>
angular.widget('my:watch', function(compileElement) {
var compiler = this;
var exp = compileElement.attr('exp');
return function(linkElement) {
var currentScope = this;
currentScope.$watch(exp, function(value){
alert(value);
});
};
});
</pre>
# Creating a Custom Attribute Widget
Let's implement the same widget as in the example in Defining an Element Widget, but this time as
an attribute that can be added to any existing DOM element:
<pre>
// An attribute widget (my:watch) in a div tag
<div my:watch="name">text</div>
</pre>
You can implement `my:watch` attribute like this:
<pre>
angular.widget('@my:watch', function(expression, compileElement) {
var compiler = this;
return function(linkElement) {

Widgets are DOM elements that the browser doesn't already understand. Angular provides some

own custom widgets.
Widgets are intended to manipulate the DOM tree by adding new elements (unlike {@link

properties).
Widgets come in two types:
* Element Widget — A custom DOM element. An example of a custom element is shown in {@link

* Attribute Widget — A custom attribute on an existing DOM element. An attribute widget is similar
to an angular directive, with the main difference being that an attribute widget will always be
processed before any directives that are specified on the same element. Only one attribute widget
is allowed per element. An example of an attribute widget is shown in {@link

@name Developer Guide: About Dependency Injection (DI)
@description
Dependency Injection (DI) is an object-oriented software design pattern that supports the
decoupling and dependency management of application components.
The idea behind DI is to decouple each component from all of the other components that it depends
on to do its particular job. The way this is done in DI is by moving the responsibility for
managing dependencies out of each individual component and into a provider component. The provider
(or injector) component manages the life cycles and dependencies for all of the other components in
an application.
Angular has a built-in dependency management subsystem that helps to make your applications easier
to develop, understand, and test.
For more information on DI in general, see {@link http://en.wikipedia.org/wiki/Dependency_injection
Dependency Injection} at Wikipedia, and {@link http://martinfowler.com/articles/injection.html
Inversion of Control} by Martin Fowler, or read about DI in your favorite software design pattern

@ngdoc overview
@name Developer Guide: DI: Understanding DI in Angular
@description
While DI is widely used in statically typed languages such as Java or C++, it has not been widely
used in JavaScript. Angular brings the benefits of DI into JavaScript apps.
In angular, DI is implemented as a subsystem that manages dependencies between services,
controllers, widgets, and filters. The most important of these are {@link api/angular.service
services}.
Services are objects that handle common tasks in web applications. Angular provides several{@link
api/angular.service built-in services}, and you can create your own custom services.
The main job of angular's DI subsystem is to provide services to angular components that depend on
them. The way the DI subsystem provides services is as follows: all services are registered with
angular's {@link api/angular.service service API}, and all components that depend on services
define those dependencies as a property (`$inject`). With this information, the DI subsystem
manages the creation of service objects and the provision of those objects to the components that
need them, at the time they need them. The following illustration steps through the sequence of
events:
<img src="img/guide/di_sequence_final.png">
In the illustration above, the dependency injection sequence proceeds as follows:
1. Service factory functions are registered with angular's service factory repository.
2. `ng:autobind` triggers angular's bootstrap sequence, during which angular compiles the template,
creates the root scope, and creates the dependency injector.
3. The `ng:controller` directive implicitly creates a new child scope, augmented by the application
of the `PhoneListCtrl` controller function.
4. The Injector identifies the `$xhr` service as `PhoneListCtrl` controller's only dependency.
5. The Injector checks if the `$xhr` service has already been instantiated, and if not uses the
factory function from the service factory repository to construct it.
6. DI provides the instance of $xhr service to the PhoneListCtrl controller constructor
## How Scope Relates to DI
The {@link api/angular.injector injector} is responsible for resolving the service dependencies in
the application. It gets created and configured with the creation of a root scope. The injector
caches instances of services, with the services cache bound to the root scope.
Different root scopes have different instances of the injector. While typical angular applications
will only have one root scope (and hence the services will act like application singletons), in
tests it is important to not share singletons across test invocations for isolation reasons. We
achieve the necessary isolation by having each test create its own separate root scope.
<pre>
// create a root scope
var rootScope = angular.scope();
// access the service locator
var myService = rootScope.$service('myService');
</pre>
## Inferring dependencies from the signature of the factory function or constructor
**EXPERIMENTAL FEATURE**: This is an experimental feature. See the important note at the end of
this section for drawbacks.
We resort to `$inject` and our own annotation because there is no way in JavaScript to get a list
of arguments. Or is there? It turns out that calling `.toString()` on a function returns the
function declaration along with the argument names as shown below:
<pre>
function myFn(a,b){}
expect(myFn.toString()).toEqual('function myFn(a,b){}');
</pre>
This means that angular can infer the function names after all and use that information to generate
the `$inject` annotation automatically. Therefore the following two function definitions are
equivalent:
<pre>
// given a user defined service
angular.service('serviceA', ...);
// inject '$window', 'serviceA', curry 'name';
function fnA($window, serviceA, name){};
fnA.$inject = ['$window', 'serviceA'];
// inject '$window', 'serviceA', curry 'name';
function fnB($window, serviceA_, name){};
// implies: fnB.$inject = ['$window', 'serviceA'];
</pre>
If angular does not find a `$inject` annotation on the function, then it calls the `.toString()`
method and tries to infer what should be injected by using function argument names as dependency
identifiers.
**IMPORTANT**
Minifiers/obfuscators change the names of function arguments and will therefore break the `$inject`
inference. For this reason, either explicitly declare the `$inject` or do not use
minifiers/obfuscators. In the future, we may provide a pre-processor which will scan the source
code and insert the `$inject` into the source code so that it can be minified/obfuscated.

@name Developer Guide: DI: Using DI in Controllers
@description
The most common place to use dependency injection in angular applications is in {@link
dev_guide.mvc.understanding_controller controllers}. Here is a simple example:
<pre>
function MyController($route){
// configure the route service
$route.when(...);
}
MyController.$inject = ['$route'];
</pre>
In this example, the `MyController` constructor function takes one argument, the {@link
api/angular.service.$route $route} service. Angular is then responsible for supplying the instance
of `$route` to the controller when the constructor is instantiated. There are two ways to cause
controller instantiation by configuring routes with the `$route` service, or by referencing the
controller from the HTML template, as follows:
<pre>
<!doctype html>
<html xmlns:ng="http://angularjs.org" ng:controller="MyController">
<script src="http://code.angularjs.org/angular.min.js" ng:autobind></script>
<body>
...
</body>
</html>
</pre>
When angular is instantiating your controller, it needs to know what services, if any, should be
injected (passed in as arguments) into the controller. Since there is no reflection in JavaScript,
we have to supply this information to angular in the form of an additional property on the
controller constructor function called `$inject`. Think of it as annotations for JavaScript.
<pre>
MyController.$inject = ['$route'];
</pre>
The information in `$inject` is then used by the {@link api/angular.injector injector} to call the
function with the correct arguments.

@name Developer Guide: E2E Testing
@description
As applications grow in size and complexity, it becomes unrealistic to rely on manual testing to
verify the correctness of new features, catch bugs and notice regressions.
To solve this problem, we have built an Angular Scenario Runner which simulates user interactions
that will help you verify the health of your Angular application.
# Overview
You will write scenario tests in JavaScript, which describe how your application should behave,
given a certain interaction in a specific state. A scenario is comprised of one or more it blocks
(you can think of these as the requirements of your application), which in turn are made of
**commands** and **expectations**. Commands tell the Runner to do something with the application
(such as navigate to a page or click on a button), and expectations tell the Runner to assert
something about the state (such as the value of a field or the current URL). If any expectation
fails, the runner marks the `it` as "failed" and continues on to the next one. Scenarios may also
have **beforeEach** and **afterEach** blocks, which will be run before (or after) each `it` block,
regardless of whether they pass or fail.
<img src="img/guide/scenario_runner.png">
In addition to the above elements, scenarios may also contain helper functions to avoid duplicating
code in the `it` blocks.
Here is an example of a simple scenario:
<pre>
describe('Buzz Client', function() {
it('should filter results', function() {
input('user').enter('jacksparrow');
element(':button').click();
expect(repeater('ul li').count()).toEqual(10);
input('filterText').enter('Bees');
expect(repeater('ul li').count()).toEqual(1);
});
});
</pre>
This scenario describes the requirements of a Buzz Client, specifically, that it should be able to
filter the stream of the user. It starts by entering a value in the 'user' input field, clicking
the only button on the page, and then it verifies that there are 10 items listed. It then enters
'Bees' in the 'filterText' input field and verifies that the list is reduced to a single item.
The API section below lists the available commands and expectations for the Runner.
# API
Source: {@link https://github.com/angular/angular.js/blob/master/src/ngScenario/dsl.js}
## pause()

output. Use this when the destination URL is dynamic (that is, the destination is unknown when you
write the test).
## browser().reload()
Refreshes the currently loaded page in the test frame.
## browser().window().href()
Returns the window.location.href of the currently loaded page in the test frame.
## browser().window().path()
Returns the window.location.pathname of the currently loaded page in the test frame.
## browser().window().search()

Returns the number of elements that match the given jQuery `selector`. The `label` is used for test
output.
## element(selector, label).click()
Clicks on the element matching the given jQuery `selector`. The `label` is used for test output.
## element(selector, label).query(fn)
Executes the function `fn(selectedElements, done)`, where selectedElements are the elements that
match the given jQuery `selector` and `done` is a function that is called at the end of the `fn`
function. The `label` is used for test output.
## element(selector, label).{method}()

JavaScript is a dynamically typed language which comes with great power of expression, but it also
come with almost no-help from the compiler. For this reason we feel very strongly that any code
written in JavaScript needs to come with a strong set of tests. We have built many features into
angular which makes testing your angular applications easy. So there is no excuse for not do it.

@name Developer Guide: Understanding Angular Expressions
@description
Expressions are {@link dev_guide.templates.databinding bindings} that you write in HTML and embed
in templates in order to create views in angular. Angular expressions are similar but not
equivalent to JavaScript expressions.
For example, these are all valid expressions in angular:
* `1+2={{1+2}}`
* `3*10|currency`
* `Hello {{name}}!`
* `Hello {{'World'}}!`
## Angular Expressions vs. JS Expressions
It might be tempting to think of angular view expressions as JavaScript expressions, but that is
not entirely correct. Angular does not use a simple JavaScript eval of the expression text. You can
think of angular expressions as JavaScript expressions with these differences:
* **Attribute Evaluation:** evaluation of all attributes are against the current scope, not to the
global window as in JavaScript.
* **Forgiving:** expression evaluation is forgiving to undefined and null, unlike in JavaScript.
* **No Control Flow Statements:** you cannot do the following from an angular expression:
conditionals, loops, or throw.
* **Type Augmentation:** the scope expression evaluator augments built-in types.
* **Filters:** you can add filters to an expression, for example to convert raw data into a
human-readable format.
* **The $:** angular reserves this prefix to differentiate its API names from others.
If, on the other hand, you do want to run arbitrary JavaScript code, you should make it a
controller method and call that. If you want to `eval()` an angular expression from JavaScript, use
the `Scope:$eval()` method.
## Example
<doc:example>
<doc:source>
1+2={{1+2}}
</doc:source>
<doc:scenario>
it('should calculate expression in binding', function(){
expect(binding('1+2')).toEqual('3');
});
</doc:scenario>
</doc:example>
You can try evaluating different expressions here:
<doc:example>
<doc:source>
<div ng:init="exprs=[]" class="expressions">
Expression:
<input type='text' name="expr" value="3*10|currency" size="80"/>
<button ng:click="exprs.$add(expr)">Evaluate</button>
<ul>
<li ng:repeat="expr in exprs">
[ <a href="" ng:click="exprs.$remove(expr)">X</a> ]
<tt>{{expr}}</tt> => <span ng:bind="$parent.$eval(expr)"></span>
</li>
</ul>
</div>
</doc:source>
<doc:scenario>
it('should allow user expression testing', function(){
element('.expressions :button').click();
var li = using('.expressions ul').repeater('li');
expect(li.count()).toBe(1);
expect(li.row(0)).toEqual(["3*10|currency", "$30.00"]);
});
</doc:scenario>
</doc:example>
# Attribute Evaluation
Evaluation of all attributes takes place against the current scope. Unlike JavaScript, where names
default to global window properties, angular expressions have to use `$window` to refer to the
global object. For example, if you want to call `alert()`, which is defined on `window`, an
expression must use `$window.alert()`. This is done intentionally to prevent accidental access to
the global state (a common source of subtle bugs).
<doc:example>
<doc:source>
<div class="example2" ng:init="$window = $service('$window')">
Name: <input name="name" type="text" value="World"/>
<button ng:click="($window.mockWindow || $window).alert('Hello ' + name)">Greet</button>
</div>
</doc:source>
<doc:scenario>
it('should calculate expression in binding', function(){
var alertText;
this.addFutureAction('set mock', function($window, $document, done) {
$window.mockWindow = {
alert: function(text){ alertText = text; }
};
done();
});
element(':button:contains(Greet)').click();
expect(this.addFuture('alert text', function(done) {
done(null, alertText);
})).toBe('Hello World');
});
</doc:scenario>
</doc:example>
## Forgiving
Expression evaluation is forgiving to undefined and null. In JavaScript, evaluating `a.b.c` throws
an exception if `a` is not an object. While this makes sense for a general purpose language, the
expression evaluations are primarily used for data binding, which often look like this:
{{a.b.c}}
It makes more sense to show nothing than to throw an exception if `a` is undefined (perhaps we are
waiting for the server response, and it will become defined soon). If expression evaluation wasn't
forgiving we'd have to write bindings that clutter the code, for example: `{{((a||{}).b||{}).c}}`
Similarly, invoking a function `a.b.c()` on undefined or null simply returns undefined.
Assignments work the same way in reverse:
a.b.c = 10
...creates the intermediary objects even if a is undefined.
## No Control Flow Statements
You cannot write a control flow statement in an expression. The reason behind this is core to the
angular philosophy that application logic should be in controllers, not in the view. If you need a
conditional (including ternary operators), loop, or to throw from a view expression, delegate to a
JavaScript method instead.
## Type Augmentation
Built-in types have methods like `[].push()`, but the richness of these methods is limited.
Consider the example below, which allows you to do a simple search over a canned set of contacts.
The example would be much more complicated if we did not have the `Array:$filter()`. There is no
built-in method on `Array` called {@link api/angular.Array.filter $filter} and angular doesn't add
it to `Array.prototype` because that could collide with other JavaScript frameworks.
For this reason the scope expression evaluator augments the built-in types to make them act like
they have extra methods. The actual method for `$filter()` is `angular.Array.filter()`. You can
call it from JavaScript.
Extensions: You can further extend the expression vocabulary by adding new methods to
`angular.Array` or `angular.String`, etc.
<doc:example>
<doc:source>
<div ng:init="friends = [
{name:'John', phone:'555-1212'},
{name:'Mary', phone:'555-9876'},
{name:'Mike', phone:'555-4321'},
{name:'Adam', phone:'555-5678'},
{name:'Julie', phone:'555-8765'}]"></div>
Search: <input name="searchText"/>
<table class="example3">
<tr><th>Name</th><th>Phone</th><tr>
<tr ng:repeat="friend in friends.$filter(searchText)">
<td>{{friend.name}}</td>
<td>{{friend.phone}}</td>
</tr>
</table>
</doc:source>
<doc:scenario>
it('should filter the list', function(){
var tr = using('table.example3').repeater('tr.ng-attr-widget');
expect(tr.count()).toBe(5);
input('searchText').enter('a');
expect(tr.count()).toBe(2);
});
</doc:scenario>
</doc:example>
## Filters
When presenting data to the user, you might need to convert the data from its raw format to a
user-friendly format. For example, you might have a data object that needs to be formatted
according to the locale before displaying it to the user. You can pass expressions through a chain
of filters like this:
name | uppercase
The expression evaluator simply passes the value of name to angular.filter.uppercase.
Chain filters using this syntax:
value | filter1 | filter2
You can also pass colon-delimited arguments to filters, for example, to display the number 123 with
2 decimal points:
123 | number:2
# The $
You might be wondering, what is the significance of the $ prefix? It is simply a prefix that
angular uses, to differentiate its API names from others. If angular didn't use $, then evaluating
`a.length()` would return undefined because neither a nor angular define such a property.
Consider that in a future version of angular we might choose to add a length method, in which case
the behavior of the expression would change. Worse yet, you the developer could create a length
property and then we would have a collision. This problem exists because angular augments existing
objects with additional behavior. By prefixing its additions with $ we are reserving our namespace
so that angular developers and developers who use angular can develop in harmony without collisions.

You set up the initial state of a scope by creating model properties. For example:

The `GreetingCtrl` controller creates a `greeting` model which can be referred to in a template.

function becomes the scope of the angular scope object, so any assignment to `this` within the

# What Is Angular?
The short answer: angular is a new, powerful, client-side technology that makes it much easier for
you to create dynamic web sites and complex web apps, all without leaving the comfort of your HTML
/ JavaScript home.
The long answer: it depends on where you're coming from...
* If you're a web designer, you might perceive angular to be a sweet {@link dev_guide.templates
templating} system, that doesn't get in your way and provides you with lots of nice built-ins that
make it easier to do what you want to do.
* If you're a web developer, you might be thrilled that angular functions as an excellent web
framework, one that assists you all the way through the development cycle.
* If you want to go deeper, you can immerse yourself in angular's extensible HTML {@link
dev_guide.compiler compiler} that runs in your browser. The angular compiler teaches your browser
new tricks.
Angular is not just a templating system, but you can create fantastic templates with it. Angular is
not just a web framework, but it features a very nice framework. Angular is not just an extensible
HTML compiler, but the compiler is at the core of Angular. Angular includes all of these
components, along with others. Angular is far greater than the sum of its parts. It is a new,
better way to develop web applications!
## An Introductory Angular Example
Let's say that you are a web designer, and you've spent many thous — erm, hundreds of hours
designing web sites. But at this point, the thought of manipulating the DOM, writing listeners and
input validators, all just to implement a simple form? No. You either don't want to go there in
the first place or you've been there and the thrill is gone.
So look over the following simple example written using angular. Note that it features only the
templating aspect of angular, but this should suffice for now to quickly demonstrate how much
easier a web developer's life can if they're using angular:
<doc:example>
<doc:source>
<b>Invoice:</b>
<br />
<br />
<table>
<tr><td> </td><td> </td>
<tr><td>Quantity</td><td>Cost</td></tr>
<tr>
<td><input name="qty" value="1" ng:validate="integer:0" ng:required /></td>
<td><input name="cost" value="19.95" ng:validate="number" ng:required /></td>
</tr>
</table>
<hr />
<b>Total:</b> {{qty * cost | currency}}
</doc:source>
<!--
<doc:scenario>
it('should show of angular binding', function(){
expect(binding('qty * cost')).toEqual('$19.95');
input('qty').enter('2');
input('cost').enter('5.00');
expect(binding('qty * cost')).toEqual('$10.00');
});
</doc:scenario>
-->
</doc:example>
Try out the Live Preview above, and then let's walk through the example and describe what's going
on.
In the `<html>` tag, we add an attribute to let the browser know about the angular namespace:
<html xmlns:ng="http://angularjs.org">
This ensures angular runs nicely in all major browsers.
In the `<script>` tag we do two angular setup tasks:
1. We load `angular.js`.
2. The angular {@link api/angular.directive.ng:autobind ng:autobind} directive tells angular to
{@link dev_guide.compiler compile} and manage the whole HTML document.
`<script src="http://code.angularjs.org/0.9.15/angular-0.9.15.min.js"
ng:autobind></script>`
From the `name` attribute of the `<input>` tags, angular automatically sets up two-way data
binding, and we also demonstrate some easy input validation:
Quantity: <input name="qty" value="1" ng:validate="integer:0" ng:required/>
Cost: <input name="cost" value="199.95" ng:validate="number" ng:required/>
These input widgets look normal enough, but consider these points:
* When this page loaded, angular bound the names of the input widgets (`qty` and `cost`) to
variables of the same name. Think of those variables as the "Model" component of the
Model-View-Controller design pattern.
* Note the angular directives, {@link api/angular.widget.@ng:validate ng:validate} and {@link
api/angular.widget.@ng:required ng:required}. You may have noticed that when you enter invalid data
or leave the the input fields blank, the borders turn red color, and the display value disappears.
These `ng:` directives make it easier to implement field validators than coding them in JavaScript,
no? Yes.
And finally, the mysterious `{{ double curly braces }}`:
Total: {{qty * cost | currency}}
This notation, `{{ _expression_ }}`, is a bit of built-in angular {@link dev_guide.compiler.markup
markup}, a shortcut for displaying data to the user. The expression within curly braces gets
transformed by the angular compiler into an angular directive ({@link api/angular.directive.ng:bind
ng:bind}). The expression itself can be a combination of both an expression and a {@link
dev_guide.templates.filters filter}: `{{ expression | filter }}`. Angular provides filters for
formatting display data.
In the example above, the expression in double-curly braces directs angular to, "Bind the data we
got from the input widgets to the display, multiply them together, and format the resulting number
into output that looks like money."
# The Angular Philosophy
Angular is built around the belief that declarative code is better than imperative when it comes to
building UIs and wiring software components together, while imperative code is excellent for
expressing business logic.
Not to put too fine a point on it, but if you wanted to add a new label to your application, you
could do so by simply adding text to the HTML template, saving the code, and refreshing your
browser:
<pre>
<span class="label">Hello</span>
</pre>
Or, as in programmatic systems (like {@link http://code.google.com/webtoolkit/ GWT}), you would
have to write the code and then run the code like this:
<pre>
var label = new Label();
label.setText('Hello');
label.setClass('label');
parent.addChild(label);
</pre>
That's one line of markup versus four times as much code.
## More Angular Philosophy
* It is a very good idea to decouple DOM manipulation from app logic. This dramatically improves
the testability of the code.
* It is a really, _really_ good idea to regard app testing as equal in importance to app writing.
Testing difficulty is dramatically affected by the way the code is structured.
* It is an excellent idea to decouple the client side of an app from the server side. This allows
development work to progress in parallel, and allows for reuse of both sides.
* It is very helpful indeed if the framework guides developers through the entire journey of
building an app: from designing the UI, through writing the business logic, to testing.
* It is always good to make common tasks trivial and difficult tasks possible.
Now that we're homing in on what angular is, perhaps now would be a good time to list a few things
that angular is not:
* It's not a Library. You don't just call its functions, although it does provide you with some
utility APIs.
* It's not a DOM Manipulation Library. Angular uses jQuery to manipulate the DOM behind the scenes,
rather than give you functions to manipulate the DOM yourself.
* It's not a Widget Library. There are lots of existing widget libraries that you can integrate
with angular.
* It's not "Just Another Templating System". A part of angular is a templating system. The
templating subsystem of angular is different from the traditional approach for these reasons:
* It Uses HTML/CSS syntax: This makes it easy to read and can be edited with existing HTML/CSS
authoring tools.
* It Extends HTML vocabulary: Angular allows you to create new HTML tags, which expand into
dynamic UI components.
* It Executes in the browser: Removes the round trip to the server for many operations and
creates instant feedback for users as well as developers.
* It Has Bidirectional data binding: The model is the single source of truth. Programmatic
changes to the model are automatically reflected in the view. Any changes by the user to the view
are automatically reflected in the model.
# Why You Want Angular
Angular frees you from the following pain:
* **Registering callbacks:** Registering callbacks clutters your code, making it hard to see the
forest for the trees. Removing common boilerplate code such as callbacks is a good thing. It vastly
reduces the amount of JavaScript coding _you_ have to do, and it makes it easier to see what your
application does.
* **Manipulating HTML DOM programatically:** Manipulating HTML DOM is a cornerstone of AJAX
applications, but it's cumbersome and error-prone. By declaratively describing how the UI should
change as your application state changes, you are freed from low level DOM manipulation tasks. Most
applications written with angular never have to programatically manipulate the DOM, although you
can if you want to.
* **Marshaling data to and from the UI:** CRUD operations make up the majority of AJAX
applications. The flow of marshaling data from the server to an internal object to an HTML form,
allowing users to modify the form, validating the form, displaying validation errors, returning to
an internal model, and then back to the server, creates a lot of boilerplate code. Angular
eliminates almost all of this boilerplate, leaving code that describes the overall flow of the
application rather than all of the implementation details.
* **Writing tons of initialization code just to get started:** Typically you need to write a lot of
plumbing just to get a basic "Hello World" AJAX app working. With angular you can bootstrap your
app easily using services, which are auto-injected into your application in a {@link
http://code.google.com/p/google-guice/ Guice}-like dependency-injection style. This allows you to
get started developing features quickly. As a bonus, you get full control over the initialization
process in automated tests.

@ngdoc overview
@name Developer Guide: Scopes: Scope Internals
@description
## What is a scope?
A scope is an execution context for {@link dev_guide.expressions expressions}. You can think of a
scope as a JavaScript object that has an extra set of APIs for registering change listeners and for
managing its own life cycle. In Angular's implementation of the model-view-controller design
pattern, a scope's properties comprise both the model and the controller methods.
### Scope characteristics
- Scopes provide APIs ({@link api/angular.scope.$watch $watch}) to observe model mutations.
- Scopes provide APIs ({@link api/angular.scope.$apply $apply}) to propagate any model changes
through the system into the view from outside of the "Angular realm" (controllers, services,
Angular event handlers).
- Scopes can be nested to isolate application components while providing access to shared model
properties. A scope (prototypically) inherits properties from its parent scope.
- In some parts of the system (such as controllers, services and directives), the scope is made
available as `this` within the given context. (Note: This api will change before 1.0 is released.)
### Root scope
Every application has a root scope, which is the ancestor of all other scopes. The root scope is
responsible for creating the injector which is assigned to the {@link api/angular.scope.$service
$service} property, and initializing the services.
### What is scope used for?
{@link dev_guide.expressions Expressions} in the view are {@link api/angular.scope.$eval evaluated}
against the current scope. When HTML DOM elements are attached to a scope, expressions in those
elements are evaluated against the attached scope.
There are two kinds of expressions:
- Binding expressions, which are observations of property changes. Property changes are reflected
in the view during the {@link api/angular.scope.$digest digest cycle}.
- Action expressions, which are expressions with side effects. Typically, the side effects cause
execution of a method in a controller in response to a user action, such as clicking on a button.
### Scope inheritance
A scope (prototypically) inherits properties from its parent scope. Since a given property may not
reside on a child scope, if a property read does not find the property on a scope, the read will
recursively check the parent scope, grandparent scope, etc. all the way to the root scope before
defaulting to undefined.
{@link api/angular.directive Directives} associated with elements (ng:controller, ng:repeat,
ng:include, etc.) create new child scopes that inherit properties from the current parent scope.
Any code in Angular is free to create a new scope. Whether or not your code does so is an
implementation detail of the directive, that is, you can decide when or if this happens.
Inheritance typically mimics HTML DOM element nesting, but does not do so with the same
granularity.
A property write will always write to the current scope. This means that a write can hide a parent
property within the scope it writes to, as shown in the following example.
<pre>
var root = angular.scope();
var child = root.$new();
root.name = 'angular';
expect(child.name).toEqual('angular');
expect(root.name).toEqual('angular');
child.name = 'super-heroic framework';
expect(child.name).toEqual('super-heroic framework');
expect(root.name).toEqual('angular');
</pre>
### Scope life cycle
1. **Creation**
* You can create the root scope via {@link api/angular.scope angular.scope()}.
* To create a child scopes, you should call {@link api/angular.scope.$new parentScope.$new()}.
2. **Watcher registration**
Watcher registration can happen at any time and on any scope (root or child) via {@link
api/angular.scope.$watch scope.$watch()} API.
3. **Model mutation**
For mutations to be properly observed, you should make them only within the execution of the
function passed into {@link api/angular.scope.$apply scope.$apply()} call. (Angular apis do this
implicitly, so no extra `$apply` call is needed when doing synchronous work in controllers, or
asynchronous work with {@link api/angular.service.$xhr $xhr} or {@link api/angular.service.$defer
$defer} services.
4. **Mutation observation**
At the end of each `$apply` call {@link api/angular.scope.$digest $digest} cycle is started on
the root scope, which then propagates throughout all child scopes.
During the `$digest` cycle, all `$watch-ers` expressions or functions are checked for model
mutation and if a mutation is detected, the `$watch-er` listener is called.
5. **Scope destruction**
When child scopes are no longer needed, it is the responsibility of the child scope creator to
destroy them via {@link api/angular.scope.$destroy scope.$destroy()} API. This will stop
propagation of `$digest` calls into the child scope and allow for memory used by the child scope
models to be reclaimed by the garbage collector.
The root scope can't be destroyed via the `$destroy` API. Instead, it is enough to remove all
references from your application to the scope object and garbage collector will do its magic.
## Scopes in Angular applications
To understand how Angular applications work, you need to understand how scopes work within an
application. This section describes the typical life cycle of an application so you can see how
scopes come into play throughout and get a sense of their interactions.
### How scopes interact in applications
1. At application compile time, a root scope is created and is attached to the root `<HTML>` DOM
element.
1. The root scope creates an {@link api/angular.injector injector} which is assigned to the
{@link api/angular.scope.$service $service} property of the root scope.
2. Any eager {@link api/angular.scope.$service services} are initialized at this point.
2. During the compilation phase, the {@link dev_guide.compiler compiler} matches {@link
api/angular.directive directives} against the DOM template. The directives usually fall into one of
two categories:
- Observing {@link api/angular.directive directives}, such as double-curly expressions
`{{expression}}`, register listeners using the {@link api/angular.scope.$watch $watch()} method.
This type of directive needs to be notified whenever the expression changes so that it can update
the view.
- Listener directives, such as {@link api/angular.directive.ng:click ng:click}, register a
listener with the DOM. When the DOM listener fires, the directive executes the associated
expression and updates the view using the {@link api/angular.scope.$apply $apply()} method.
3. When an external event (such as a user action, timer or XHR) is received, the associated {@link
dev_guide.expressions expression} must be applied to the scope through the {@link
api/angular.scope.$apply $apply()} method so that all listeners are updated correctly.
### Directives that create scopes
In most cases, {@link api/angular.directive directives} and scopes interact but do not create new
instances of scope. However, some directives, such as {@link api/angular.directive.ng:controller
ng:controller} and {@link api/angular.widget.@ng:repeat ng:repeat}, create new child scopes using
the {@link api/angular.scope.$new $new()} method and then attach the child scope to the
corresponding DOM element. You can retrieve a scope for any DOM element by using an
`angular.element(aDomElement).scope()` method call.)
### Controllers and scopes
Scopes and controllers interact with each other in the following situations:
- Controllers use scopes to expose controller methods to templates (see {@link
api/angular.directive.ng:controller ng:controller}).
- Controllers define methods (behavior) that can mutate the model (properties on the scope).
- Controllers may register {@link api/angular.scope.$watch watches} on the model. These watches
execute immediately after the controller behavior executes, but before the DOM gets updated.
See the {@link dev_guide.mvc.understanding_controller controller docs} for more information.
### Updating scope properties
You can update a scope by calling its {@link api/angular.scope.$apply $apply()} method with an
expression or a function as the function argument. However it is typically not necessary to do this
explicitly. In most cases, angular intercepts all external events (such as user interactions, XHRs,
and timers) and wraps their callbacks into the `$apply()` method call on the scope object for you
at the right time. The only time you might need to call `$apply()` explicitly is when you create
your own custom asynchronous widget or service.
The reason it is unnecessary to call `$apply()` from within your controller functions when you use
built-in angular widgets and services is because your controllers are typically called from within
an `$apply()` call already.
When a user inputs data, angularized widgets invoke `$apply()` on the current scope and evaluate an
angular expression or execute a function on this scope. Afterwards `$apply` will trigger `$digest`
call on the root scope, to propagate your changes through the entire system, which results in
$watch-ers firing and view getting updated. Similarly, when a request to fetch data from a server
is made and the response comes back, the data is written into the model (scope) within an $apply,
which then pushes updates through to the view and any other dependents.
A widget that creates scopes (such as {@link api/angular.widget.@ng:repeat ng:repeat}) via `$new`,
doesn't need to worry about propagating the `$digest` call from the parent scope to child scopes.
This happens automatically.
## Scopes in unit-testing
You can create scopes, including the root scope, in tests using the {@link api/angular.scope
angular.scope()} API. This allows you to mimic the run-time environment and have full control over
the life cycle of the scope so that you can assert correct model transitions. Since these scopes
are created outside the normal compilation process, their life cycles must be managed by the test.
### Using scopes in unit-testing
The following example demonstrates how the scope life cycle needs to be manually triggered from
within the unit-tests.
<pre>
// example of a test
var scope = angular.scope();
scope.$watch('name', function(scope, name){
scope.greeting = 'Hello ' + name + '!';
});
scope.name = 'angular';
// The watch does not fire yet since we have to manually trigger the digest phase.
expect(scope.greeting).toEqual(undefined);
// manually trigger digest phase from the test
scope.$digest();
expect(scope.greeting).toEqual('Hello Angular!');
</pre>
### Dependency injection in Tests
When you find it necessary to inject your own mocks in your tests, use a scope to override the
service instances, as shown in the following example.
<pre>
var myLocation = {};
var scope = angular.scope(angular.service, {$location: myLocation});
expect(scope.$service('$location')).toEqual(myLocation);
</pre>

An Angular scope is a JavaScript object with additional APIs useful for watching property changes,
Angular scope is the model in Model-View-Controller paradigm. Instances of scope serve as the
context within which all {@link dev_guide.expressions expressions} get evaluated.
You can think of Angular scope objects as the medium through which the model, view, and controller
communicate. Scopes are linked during the compilation process with the view. This linkage provides
the contexts in which Angular creates data-bindings between the model and the view.
In addition to providing the context in which data is evaluated, Angular scope objects watch for
model changes. The scope objects also notify all components interested in any model changes (for
example, functions registered through {@link api/angular.scope.$watch $watch}, bindings created by
{@link api/angular.directive.ng:bind ng:bind}, or HTML input elements).
Angular scope objects:
* Link the model, controller and view template together.
* Provide the mechanism to watch for model changes ({@link api/angular.scope.$watch $watch}).
* Apply model changes to the system ({@link api/angular.scope.$apply $apply}).
* Provide the context in which expressions are evaluated ({@link api/angular.scope.$eval $eval}).

@ngdoc overview
@name Developer Guide: Scopes: Understanding Scopes
@description
Angular automatically creates a root scope during initialization, and attaches it to the page's
root DOM element (usually `<html>`). The root scope object, along with any of its child scope
objects, serves as the infrastructure on which your data model is built. The data model (JavaScript
objects, arrays, or primitives) is attached to angular scope properties. Angular binds the property
values to the DOM where bindings are specified in the template. Angular attaches any controller
functions you have created to their respective scope objects.
<img src="img/guide/simple_scope_final.png">
Angular scopes can be nested, so a child scope has a parent scope upstream in the DOM. When you
display an angular expression in the view, angular walks the DOM tree looking in the closest
attached scope object for the specified data. If it doesn't find the data in the closest attached
scope, it looks further up the scope hierarchy until it finds the data.
A child scope object inherits properties from its parents. For example, in the following snippet of
code, observe how the value of `name` changes, based on the HTML element it is displayed in:
<doc:example>
<doc:source>
<ul ng:init="name='Hank'; names=['Igor', 'Misko', 'Gail', 'Kai']">
<li ng:repeat="name in names">
Name = {{name}}!
</li>
</ul>
<pre>Name={{name}}</pre>
</doc:source>
<doc:scenario>
it('should override the name property', function() {
expect(using('.doc-example-live').repeater('li').row(0)).
toEqual(['Igor']);
expect(using('.doc-example-live').repeater('li').row(1)).
toEqual(['Misko']);
expect(using('.doc-example-live').repeater('li').row(2)).
toEqual(['Gail']);
expect(using('.doc-example-live').repeater('li').row(3)).
toEqual(['Kai']);
expect(using('.doc-example-live').element('pre').text()).
toBe('Name=Hank');
});
</doc:scenario>
</doc:example>
The angular {@link api/angular.widget.@ng:repeat ng:repeat} directive creates a new scope for each
element that it repeats (in this example the elements are list items). In the `<ul>` element, we
initialized `name` to "Hank", and we created an array called `names` to use as the data source for
the list items. In each `<li>` element, `name` is overridden. Outside of the `<li>` repeater, the
original value of `name` is displayed.
The following illustration shows the DOM and angular scopes for the example above:

@description
While angular offers several useful services, for any nontrivial application you'll find it useful
to write your own custom services. To do this you begin by registering a service factory function
that angular's DI will use to create the service object when it is needed.
with a module either via the {@link api/angular.module Module#factory api} or directly
via the {@link api/AUTO.$provide $provide} api inside of module config function.
The `angular.service` method accepts three parameters:
- `{string} name` - Name of the service.
- `{function()} factory` - Factory function (called just once by DI).
- `{Object} config` - Configuration object with the following properties:
- `$inject` - {Array.<string>} - Array of service ids this service depends on. These services
will be passed as arguments into the factory function in the same order specified in the `$inject`
array. Defaults to `[]`.
- `$eager` - {boolean} - If true, the service factory will be called and the service will be
instantiated when angular boots. If false, the service will be lazily instantiated when it is first
requested during instantiation of a dependant. Defaults to `false`.
The `this` of the factory function is bound to the root scope of the angular application.
All angular services participate in {@link dev_guide.di dependency injection (DI)} by registering
themselves with angular's DI system (injector) under a `name` (id) as well as by declaring
All angular services participate in {@link di dependency injection (DI)} by registering
themselves with Angular's DI system (injector) under a `name` (id) as well as by declaring
dependencies which need to be provided for the factory function of the registered service. The
ability to swap dependencies for mocks/stubs/dummies in tests allows for services to be highly
testable.
# Registering Services
To register a service, you must have a module that this service will be part of. Afterwards, you
can register the service with the module either via the {@link api/angular.Module Module api} or
by using the {@link api/AUTO.$provide $provide} service in the module configuration
function.The following pseudo-code shows both approaches:
Using the angular.Module api:
<pre>
var myModule = angular.module('myModule', []);
myModule.factory('serviceId', function() {
var shinyNewServiceInstance;
//factory function body that constructs shinyNewServiceInstance
return shinyNewServiceInstance;
});
</pre>
Using the $provide service:
<pre>
angular.module('myModule', [], function($provide) {
$provide.factory('serviceId', function() {
var shinyNewServiceInstance;
//factory function body that constructs shinyNewServiceInstance
return shinyNewServiceInstance;
});
});
</pre>
Note that you are not registering a service instance, but rather a factory function that will
create this instance when called.
# Dependencies
Services can not only be depended upon, but also have its own dependencies. These can be specified
as arguments of the factory function. {@link di Read more} about the DI
in Angular and the use of array notation and $inject property to make DI annotation
minification-proof.
Following is an example of a very simple service. This service depends on the `$window` service
(which is passed as a parameter to the factory function) and is just a function. The service simply
stores all notifications; after the third one, the service displays all of the notifications by
window alert.
<pre>
angular.service('notify', function(win) {
var msgs = [];
return function(msg) {
msgs.push(msg);
if (msgs.length == 3) {
win.alert(msgs.join("\n"));
msgs = [];
}
};
}, {$inject: ['$window']});
angular.module('myModule', [], function($provide) {
$provide.factory('notify', ['$window', function(win) {
var msgs = [];
return function(msg) {
msgs.push(msg);
if (msgs.length == 3) {
win.alert(msgs.join("\n"));
msgs = [];
}
};
}]);
});
</pre>
# Instantiating Angular Services
All services in Angular are instantiates services lazily, this means that a service will be created
only when it is needed for instantiation of a service or an application component that depends on it.
In other words, angular won't instantiate lazy services unless they are requested directly or
indirectly by the application.
# Services as singletons
Lastly, it is important to realize that all angular services are application singletons. This means
that there is only one instance of a given service per injector. Since angular is lethally allergic
to the global state, it is possible to create multiple injectors, each with its own instance of a
given service, but that is rarely needed, except in tests where this property is crucially
important.

Since JavaScript is a dynamic language, DI can't figure out which services to inject by static

`$inject` property, which is an array containing strings with names of services to be injected.
The name must match the corresponding service ID registered with angular. The order of the service

code, your variable names will get renamed in which case you will still need to explicitly specify
dependencies with the `$inject` property.

A service can be instantiated eagerly or lazily. By default angular instantiates services lazily,
which means that a service will be created only when it is needed for instantiation of a service or
an application component that depends on it. In other words, angular won't instantiate lazy
services unless they are requested directly or indirectly by the application.
Eager services on the other hand, are instantiated right after the injector itself is created,
which happens when the angular {@link dev_guide.bootstrap application initializes}.
To override the default, you can request that a service is eagerly instantiated as follows:
<pre>
angular.service('service id', function() {
var shinyNewServiceInstance;
//factory function body that constructs shinyNewServiceInstance
return shinyNewServiceInstance;
}, {$eager: true});
</pre>
While it is tempting to declare services as eager, only in few cases it is actually useful. If you
are unsure whether to make a service eager, it likely doesn't need to be. To be more specific, a
service should be declared as eager only if it fits one of these scenarios:
* Nothing in your application declares this service as its dependency, and this service affects the
state or configuration of the application (e.g. a service that configures `$route` or `$resource`
services)
* A guarantee is needed that the service will be instantiated at application boot time, usually
because the service passively observes the application and it is optional for other application
components to depend on it. An example of this scenario is a service that monitors and logs
application memory usage.
Lastly, it is important to realize that all angular services are applicaiton singletons. This means
that there is only one instance of a given service per injector. Since angular is lethally allergic
to the global state, it is possible to create multiple injectors, each with its own instance of a
given service, but that is rarely needed, except in tests where this property is crucially
important.

Angular includes built-in CSS classes, which in turn have predefined CSS styles.
Angular sets these CSS classes. It is up to your application to provide useful styling.
# Built-in CSS classes
# CSS classes used by angular
* `ng-exception`
* `ng-invalid`, `ng-valid`
- **Usage:** angular applies this class to an input widget element if that element's input does
notpass validation. (see {@link api/ng.directive:input input} directive).
**Usage:** angular applies this class to a DOM element if that element contains an Expression that
threw an exception when evaluated.
**Styling:** The built-in styling of the ng-exception class displays an error message surrounded
by a solid red border, for example:
<div class="ng-exception">Error message</div>
You can try to evaluate malformed expressions in {@link dev_guide.expressions expressions} to see
the `ng-exception` class' styling.
* `ng-validation-error`
**Usage:** angular applies this class to an input widget element if that element's input does not
pass validation. Note that you set the validation criteria on the input widget element using the
Ng:validate or Ng:required directives.
**Styling:** The built-in styling of the ng-validation-error class turns the border of the input
box red and includes a hovering UI element that includes more details of the validation error. You
can see an example in {@link api/angular.widget.@ng:validate ng:validate example}.
## Overriding Styles for Angular CSS Classes
To override the styles for angular's built-in CSS classes, you can do any of the following:
* Download the source code, edit angular.css, and host the source on your own server.
* Create a local CSS file, overriding any styles that you'd like, and link to it from your HTML file
as you normally would:
<pre>
<link href="yourfile.css" rel="stylesheet" type="text/css">
</pre>
* `ng-pristine`, `ng-dirty`
- **Usage:** angular {@link api/ng.directive:input input} directive applies `ng-pristine` class
to a new input widget element which did not have user interaction. Once the user interacts with
the input widget the class is changed to `ng-dirty`.

@description
Writing your own filter is very easy: just define a JavaScript function on the `angular.filter`
object.
The framework passes in the input value as the first argument to your function. Any filter
arguments are passed in as additional function arguments.
You can use these variables in the function:
* `this` — The current scope.
* `this.$element` — The DOM element containing the binding. The `$element` variable allows the
filter to manipulate the DOM.
Writing your own filter is very easy: just register a new filter (injectable) factory function with
your module. This factory function should return a new filter function which takes the input value
as the first argument. Any filter arguments are passed in as additional arguments to the filter
function.
The following sample filter reverses a text string. In addition, it conditionally makes the
text upper-case and assigns color.
<doc:example>
<doc:example module="MyReverseModule">
<doc:source>
<script type="text/javascript">
angular.filter('reverse', function(input, uppercase, color) {

}

To create your own formatter, you can simply register a pair of JavaScript functions with
`angular.formatter`. One of your functions is used to parse text from the input widget into the
data storage format; the other function is used to format stored data into user-readable text.
The following example demonstrates a "reverse" formatter. Data is stored in uppercase and in
reverse, but it is displayed in lower case and non-reversed. When a user edits the data model via
the input widget, the input is automatically parsed into the internal data storage format, and when
the data changes in the model, it is automatically formatted to the user-readable form for display
in the view.

function reverse(text) {
var reversed = [];
for (var i = 0; i < text.length; i++) {
reversed.unshift(text.charAt(i));

To create a custom validator, you simply add your validator code as a method onto the

commas.
The following bit of pseudo-code shows how to set up a custom validator:

[your validation code];
if ( [validation succeeds] ) {
return false;
} else {
return true; // No error message specified
}

</pre>
Note that this validator returns "true" when the user's input is incorrect, as in "Yes, it's true,
there was a problem with that input". If you prefer to provide more information when a validator
detects a problem with input, you can specify an error message in the validator that angular will
display when the user hovers over the input widget.
To specify an error message, replace "`return true;`" with an error string, for example:
return "Must be a value between 1 and 5!";
Following is a sample UPS Tracking Number validator:

@name Developer Guide: Dependency Injection
@description
# Dependency Injection
Dependency Injection (DI) is a software design pattern that deals with how code gets hold of its
dependencies.
For in-depth discussion about DI, see {@link http://en.wikipedia.org/wiki/Dependency_injection
Dependency Injection} at Wikipedia, {@link http://martinfowler.com/articles/injection.html
Inversion of Control} by Martin Fowler, or read about DI in your favorite software design pattern
book.
## DI in a nutshell
There are only three ways how an object or a function can get a hold of its dependencies:
1. The dependency can be created, typically using the `new` operator.
2. The dependency can be looked up by referring to a global variable.
3. The dependency can be passed in to where it is needed.
The first two option of creating or looking up dependencies are not optimal, because they hard
code the dependency, making it difficult, if not impossible, to modify the dependencies.
This is especially problematic in tests, where it is often desirable to provide mock dependencies
for test isolation.
The third option is the most viable, since it removes the responsibility of locating the
dependency from the component. The dependency is simply handed to the component.
<pre>
function SomeClass(greeter) {
this.greeter = greeter
}
SomeClass.prototype.doSomething = function(name) {
this.greeter.greet(name);
}
</pre>
In the above example the `SomeClass` is not concerned with locating the `greeter` dependency, it
is simply handed the `greeter` at runtime.
This is desirable, but it puts the responsibility of getting hold of the dependency onto the
code responsible for the construction of `SomeClass`.
To manage the responsibility of dependency creation, each angular application has an {@link
api/angular.injector injector}. The injector is a service locator that is responsible for
construction and lookup of dependencies.
Here is an example of using the injector service.
<pre>
// Provide the wiring information in a module
angular.module('myModule', []).
// Teach the injector how to build a 'greeter'
// Notice that greeter itself is dependent on '$window'
factory('greeter', function($window) {
// This is a factory function, and is responsible for
// creating the 'greet' service.
return {
greet: function(text) {
$window.alert(text);
}
};
}).
// New injector is created from the module.
// (This is usually done automatically by angular bootstrap)
var injector = angular.injector('myModule');
// Request any dependency from the injector
var greeter = injector.get('greeter');
</pre>
Asking for dependencies solves the issue of hard coding, but it also means that the injector needs
to be passed throughout the application. Passing the injector breaks the {@link
http://en.wikipedia.org/wiki/Law_of_Demeter Law of Demeter}. To remedy this, we turn the
dependency lookup responsibility to the injector by declaring the dependencies as in this example:
<pre>
<!-- Given this HTML -->
<div ng-controller="MyController">
<button ng-click="sayHello()">Hello</button>
</div>
</pre>
<pre>
// And this controller definition
function MyController($scope, greeter) {
$scope.sayHello = function() {
greeter('Hello World');
};
}
// The 'ng-controller' directive does this behind the scenes
injector.instantiate(MyController);
</pre>
Notice that by having the `ng-controller` instantiate the class, it can satisfy all of the
dependencies of the `MyController` without the controller ever knowing about the injector. This is
the best outcome. The application code simply ask for the dependencies it needs, without having to
deal with the injector. This setup does not break the Law of Demeter.
# Dependency Annotation
How does the injector know what service needs to be injected?
The application developer needs to provide annotation information, that the injector uses in order
to resolve the dependencies. Throughout Angular certain API functions are invoked using the
injector, as per the API documentation. The injector needs to know what services to inject into
the function. Below are three equivalent ways of annotating your code with service name
information. These can be used interchangeably as you see fit and are equivalent.
# Inferring Dependencies
The simplest way to get hold of the dependencies, is to assume that the function parameter names
are the names of the dependencies.
<pre>
function MyController($scope, greeter) {
...
}
</pre>
Given a function the injector can infer the names of the service to inject by examining the
function declaration and extracting the parameter names. In the above example `$scope`, and
`greeter` are two services which need to be injected into the function.
While straightforward, this method will not work with JavaScript minifiers/obfuscators as they
rename the method parameter names. This makes this way of annotating only useful for {@link
http://www.pretotyping.org/ pretotyping}, and demo applications.
# `$inject` Annotation
To allow the minifers to rename the function parameters and still be able to inject right services
the function needs to be annotate with the `$inject` property. The `$inject` property is an array
of service names to inject.
<pre>
var MyController = function(renamed$scope, renamedGreeter) {
...
}
MyController.$inject = ['$scope', 'greeter'];
</pre>
Care must be taken that the `$inject` annotation is kept in sync with the actual arguments in the
function declaration.
This method of annotation is useful for controller declarations since it assigns the annotation
information with the function.
# Inline Annotation
Sometimes using the `$inject` annotation style is not convenient such as when annotating
directives.
For example:
<pre>
someModule.factory('greeter', function($window) {
...;
});
</pre>
Results in code bloat do to the need of temporary variable:
<pre>
var greeterFactory = function(renamed$window) {
...;
};
greeterFactory.$inject = ['$window'];
someModule.factory('greeter', greeterFactory);
</pre>
For this reason the third annotation style is provided as well.
<pre>
someModule.factory('greeter', ['$window', function(renamed$window) {
...;
}]);
</pre>
Keep in mind that all of the annotation styles are equivalent and can be used anywhere in Angular
where injection is supported.
# Where can I use DI?
DI is pervasive throughout Angular. It is typically used in controllers and factory methods.
## DI in controllers
Controllers are classes which are responsible for application behavior. Recommended way of
declaring controllers is:
<pre>
var MyController = function(dep1, dep2) {
...
}
MyController.$inject = ['dep1', 'dep2'];
MyController.prototype.aMethod = function() {
...
}
</pre>
## Factory methods
Factory methods are responsible for creating most objects in Angular. Examples are directives,
services, and filters. The factory methods are register with the module, and the recommended way
of declaring factories is:
<pre>
angualar.module('myModule', []).
config(['depProvider', function(depProvider){
...
}]).
factory('serviceId', ['depService', function(depService) {
...
}]).
directive('directiveName', ['depService', function(depService) {
...
}]).
filter('filterName', ['depService', function(depService) {
...
}]).
run(['depService', function(depService) {
...
}]);

@name Directives
@description
Directives are a way to teach HTML new tricks. During DOM compilation directives are matched
against the HTML and executed. This allows directives to register behavior, or transform the DOM.
Angular comes with a built in set of directives which are useful for building web applications but
can be extended such that HTML can be turned into a declarative domain specific language (DSL).
# Invoking directives from HTML
Directives have camel cased names such as 'ngBind'. The directive can be invoked by translating
the camel case name into snake case with these special characters `:`, `-`, or `_`. Optionally the
directive can be prefixed with `x-`, or `data-` to make it HTML validator compliant. Here is a
list of some of the possible directive names: `ng:bind`, `ng-bind`, `ng_bind`, `x-ng-bind` and
`data-ng-bind`.
The directives can be placed in element names, attributes, class names, as well as comments. Here
are some equivalent examples of invoking `myDir`. (However, most directives are restricted to
attribute only.)
<pre>
<span my-dir="exp"></span>
<span class="my-dir: exp;"></span>
<my-dir></my-dir>
<!-- directive: my-dir exp -->
</pre>
Directives can be invoked in many different ways, but are equivalent in the end result as shown in
the following example.
<doc:example>
<doc:source >
<script>
function Ctrl1($scope) {
$scope.name = 'angular';
}
</script>
<div ng-controller="Ctrl1">
Hello <input ng-model='name'> <hr/>
&ltspan ng:bind="name"&gt <span ng:bind="name"></span> <br/>
&ltspan ng_bind="name"&gt <span ng_bind="name"></span> <br/>
&ltspan ng-bind="name"&gt <span ng-bind="name"></span> <br/>
&ltspan data-ng-bind="name"&gt <span data-ng-bind="name"></span> <br/>
&ltspan x-ng-bind="name"&gt <span x-ng-bind="name"></span> <br/>
</div>
</doc:source>
<doc:scenario>
it('should show off bindings', function() {
expect(element('div[ng-controller="Ctrl1"] span[ng-bind]').text()).toBe('angular');
});
</doc:scenario>
</doc:example>
# String interpolation
During the compilation process the {@link api/ng.$compile compiler} matches text and
attributes using the {@link api/ng.$interpolate $interpolate} service to see if they
contain embedded expressions. These expressions are registered as {@link
api/ng.$rootScope.Scope#$watch watches} and will update as part of normal {@link
api/ng.$rootScope.Scope#$digest digest} cycle. An example of interpolation is shown
here:
<pre>
<img src="img/{{username}}.jpg">Hello {{username}}!</img>
</pre>
# Compilation process, and directive matching
Compilation of HTML happens in three phases:
1. First the HTML is parsed into DOM using the standard browser API. This is important to
realize because the templates must be parsable HTML. This is in contrast to most templating
systems that operate on strings, rather then on DOM elements.
2. The compilation of the DOM is performed by the call to {@link api/ng.$compile
$compile()} method. The method traverses the DOM and matches the directives. If a match is found
it is added to the list of directives associated with the given DOM element. Once all directives
for a given DOM element have been identified they are sorted by priority and their `compile()`
functions are executed. The directive compile function has a chance to modify the DOM structure
and is responsible for producing a `link()` function explained next. The {@link
api/ng.$compile $compile()} method returns a combined linking function, which is a
collection of all of the linking functions returned from the individual directive compile
functions.
3. Link the template with scope by calling the linking function returned from the previous step.
This in turn will call the linking function of the individual directives allowing them to
register any listeners on the elements and set up any {@link
api/ng.$rootScope.Scope#$watch watches} with the {@link
api/ng.$rootScope.Scope scope}. The result of this is a live binding between the
scope and the DOM. A change in the scope is reflected in the DOM.
<pre>
var $compile = ...; // injected into your code
var scope = ...;
var html = '<div ng-bind='exp'></div>';
// Step 1: parse HTML into DOM element
var template = angular.element(html);
// Step 2: compile the template
var linkFn = $compile(template);
// Step 3: link the compiled template with the scope.
linkFn(scope);
</pre>
## Reasons behind the compile/link separation
At this point you may wonder why is the compile process broken down to a compile and link phase.
To understand this, lets look at a real world example with repeater:
<pre>
Hello {{user}}, you have these actions:
<ul>
<li ng-repeat="action in user.actions">
{{action.description}}
</li>
</ul>
</pre>
The short answer is that compile and link separation is needed any time a change in model causes
a change in DOM structure such as in repeaters.
When the above example is compiled, the compiler visits every node and looks for directives. The
`{{user}}` is an example of {@link api/ng.$interpolate interpolation} directive. {@link
api/ng.directive:ngRepeat ngRepeat} is another directive. But {@link
api/ng.directive:ngRepeat ngRepeat} has a dilemma. It needs to be
able to quickly stamp out new `li`s for every `action` in `user.actions`. This means that it needs
to save a clean copy of the `li` element for cloning purposes and as new `action`s are inserted,
the template `li` element needs to be cloned and inserted into `ul`. But cloning the `li` element
is not enough. It also needs to compile the `li` so that its directives such as
`{{action.descriptions}}` evaluate against the right {@link api/ng.$rootScope.Scope
scope}. A naive method would be to simply insert a copy of the `li` element and then compile it.
But compiling on every `li` element clone would be slow, since the compilation requires that we
traverse the DOM tree and look for directives and execute them. If we put the compilation inside a
repeater which needs to unroll 100 items we would quickly run into performance problems.
The solution is to break the compilation process into two phases the compile phase where all of
the directives are identified and sorted by priority, and a linking phase where any work which
links a specific instance of the {@link api/ng.$rootScope.Scope scope} and the specific
instance of an `li` is performed.
{@link api/ng.directive:ngRepeat ngRepeat} works by preventing the
compilation process form descending into `li` element. Instead the {@link
api/ng.directive:ngRepeat ngRepeat} directive compiles `li`
seperatly. The result of of the `li` element compilation is a linking function which contains all
of the directives contained in the `li` element ready to be attached to a specific clone of `li`
element. At runtime the {@link api/ng.directive:ngRepeat ngRepeat}
watches the expression and as items are added to the array it clones the `li` element, creates a
new {@link api/ng.$rootScope.Scope scope} for the cloned `li` element and calls the
link function on the cloned `li`.
Summary:
* *compile function* - The compile function is relatively rare in directives, since most
directives are concerned with working with a specific DOM element instance rather then
transforming the template DOM element. Any operation which can be shared among the instance of
directives should be moved to the compile function for performance reasons.
* *link function* - It is rare for the directive not to have a link function. Link function
allows the directive to register listeners to the specific cloned DOM element instance as well
as to copy content into the DOM from the scope.
# Writing directives (short version)
In this example we will build a directive which displays the current time.
<doc:example module="time">
<doc:source>
<script>
function Ctrl2($scope) {
$scope.format = 'M/d/yy h:mm:ss a';
}
angular.module('time', [])
// Register the 'myCurrentTime' directive factory method.
// We inject $defer and dateFilter service since the factory method is DI.
.directive('myCurrentTime', function($defer, dateFilter) {
// return the directive link function. (compile function not needed)
return function(scope, element, attrs) {
var format, // date format
deferId; // deferId, so that we can cancel the time updates
// used to update the UI
function updateTime() {
element.text(dateFilter(new Date(), format));
}
// watch the expression, and update the UI on change.
scope.$watch(attrs.myCurrentTime, function(value) {
format = value;
updateTime();
});
// schedule update in one second
function updateLater() {
// save the deferId for canceling
deferId = $defer(function() {
updateTime(); // update DOM
updateLater(); // schedule another update
}, 1000);
}
// listen on DOM destroy (removal) event, and cancel the next UI update
// to prevent updating time ofter the DOM element was removed.
element.bind('$destroy', function() {
$defer.cancel(deferId);
});
updateLater(); // kick of the UI update process.
}
});
</script>
<div ng-controller="Ctrl2">
Date format: <input ng-model='format'> <hr/>
Current time is: <span my-current-time="format"></span
</div>
</doc:source>
<doc:scenario>
</doc:scenario>
</doc:example>
# Writing directives (long version)
An example skeleton of the directive is shown here, for the complete list see below.
<pre>
var myModule = angular.module(...);
myModule.directive('directiveName', function factory(injectables) {
var directiveDefinitionObject = {
priority: 0,
template: '<div></div>',
templateUrl: 'directive.html',
replace: false,
transclude: false,
restrict: 'A',
scope: false,
compile: function compile(tElement, tAttrs, transclude) {
return {
pre: function preLink(scope, iElement, iAttrs, controller) { ... },
post: function postLink(scope, iElement, iAttrs, controller) { ... }
}
},
link: function postLink(scope, iElement, iAttrs) { ... }
};
return directiveDefinitionObject;
});
</pre>
In most cases you will not need such fine control and so the above can be simplified. All of the
different parts of this skeleton are explained in following sections. In this section we are
interested only isomers of this skeleton.
The first step in simplyfing the code is to rely on the deafult values. Therefore the above can be
simplified as:
<pre>
var myModule = angular.module(...);
myModule.directive('directiveName', function factory(injectables) {
var directiveDefinitionObject = {
compile: function compile(tElement, tAttrs) {
return function postLink(scope, iElement, iAttrs) { ... }
}
};
return directiveDefinitionObject;
});
</pre>
Most directives concern themselves only with instances not with template transformations allowing
further simplification:
<pre>
var myModule = angular.module(...);
myModule.directive('directiveName', function factory(injectables) {
return function postLink(scope, iElement, iAttrs) { ... }
});
</pre>
## Factory method
The factory method is responsible for creating the directive. It is invoked only once, when the
{@link api/ng.$compile compiler} matches the directive for the first time. You can
perform any initialization work here. The method is invoked using the {@link
http://localhost:8000/build/docs/api/AUTO.$injector#invoke $injector.invoke} which
makes it injectable following all of the rules of injection annotation.
## Directive Definition Object
The directive definition object provides instructions to the {@link api/ng.$compile
compiler}. The attributes are:
* `name` - Name of the current scope. Optional defaults to the name at registration.
* `priority` - When there are multiple directives defined on a single DOM element, sometimes it
is necessary to specify the order in which the directives are applied. The `priority` is used
to sort the directives before their `compile` functions get called. Higher `priority` goes
first. The order of directives within the same priority is undefined.
* `terminal` - If set to true then the current `priority` will be the last set of directives
which will execute (any directives at the current priority will still execute
as the order of execution on same `priority` is undefined).
* `scope` - If set to:
* `true` - then a new scope will be created for this directive. If multiple directives on the
same element request new scope, only one new scope is created. The new scope rule does not
apply for the root of the template since the root of the template always gets a new scope.
* `{}` (object hash) - then a new 'isolate' scope is created. The 'isolate' scope differs from
normal scope that it does not prototypically inherit from the parent scope. This is useful
when creating reusable components, which should not accidentally read or modify data in
parent scope. <br/>
The 'isolate' scope takes an object hash which defines a set of local scope properties
derived from the parent scope. These local properties are useful for aliasing values for
templates. Locals definition is a hash of local scope property to its source:
* `@` or `@attr` - bind a local scope property to the DOM attribute. The result is always a
string since DOM attributes are strings. If no `attr` name is specified then the local name
and attribute name are same. Given `<widget my-attr="hello {{name}}">` and widget definition
of `scope: { localName:'@myAttr' }`, then widget scope property `localName` will reflect
the interpolated value of `hello {{name}}`. As the `name` attribute changes so will the
`localName` property on the widget scope. The `name` is read from the parent scope (not
component scope).
* `=` or `=expression` - set up bi-directional binding between a local scope property and the
parent scope property. If no `attr` name is specified then the local name and attribute
name are same. Given `<widget my-attr="parentModel">` and widget definition of
`scope: { localModel:'=myAttr' }`, then widget scope property `localName` will reflect the
value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
in `localModel` and any changes in `localModel` will reflect in `parentModel`.
* `&` or `&attr` - provides a way to execute an expression in the context of the parent scope.
If no `attr` name is specified then the local name and attribute name are same.
Given `<widget my-attr="count = count + value">` and widget definition of
`scope: { localFn:'increment()' }`, then isolate scope property `localFn` will point to
a function wrapper for the `increment()` expression. Often it's desirable to pass data from
the isolate scope via an expression and to the parent scope, this can be done by passing a
map of local variable names and values into the expression wrapper fn. For example if the
expression is `increment(amount)` then we can specify the amount value by calling the
`localFn` as `localFn({amount: 22})`.
* `controller` - Controller constructor function. The controller is instantiated before the
pre-linking phase and it is shared with other directives if they request it by name (see
`require` attribute). This allows the directives to communicate with each other and augment
each other behavior. The controller is injectable with the following locals:
* `$scope` - Current scope associated with the element
* `$element` - Current element
* `$attrs` - Current attributes obeject for the element
* `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
`function(cloneLinkingFn)`.
* `require` - Require another controller be passed into current directive linking function. The
`require` takes a name of the directive controller to pass in. If no such controller can be
found an error is raised. The name can be prefixed with:
* `?` - Don't raise an error. This makes the require dependency optional.
* `^` - Look for the controller on parent elements as well.
* `restrict` - String of subset of `EACM` which restricts the directive to a specific directive
declaration style. If omitted directives are allowed on attributes only.
* `E` - Element name: `<my-directive></my-directive>`
* `A` - Attribute: `<div my-directive="exp"></div>`
* `C` - Class: `<div class="my-directive: exp;"></div>`
* `M` - Comment: `<!-- directive: my-directive exp -->`
* `template` - replace the current element with the contents of the HTML. The replacement process
migrates all of the attributes / classes from the old element to the new one. See Creating
Widgets section below for more information.
* `templateUrl` - Same as `template` but the template is loaded from the specified URL. Because
the template loading is asynchronous the compilation/linking is suspended until the template
is loaded.
* `replace` - if set to `true` then the template will replace the current element, rather then
append the template to the element.
* `transclude` - compile the content of the element and make it available to the directive.
Typically used with {@link api/ng.directive:ngTransclude
ngTransclude}. The advantage of transclusion is that the linking function receives a
transclusion function which is pre-bound to the correct scope. In a typical setup the widget
creates an `isolate` scope, but the transclusion is not a child, but a sibling of the `isolate`
scope. This makes it possible for the widget to have private state, and the transclusion to
be bound to the parent (pre-`isolate`) scope.
* `true` - transclude the content of the directive.
* `'element'` - transclude the whole element including any directives defined at lower priority.
* `compile`: This is the compile function described in the section below.
* `link`: This is the link function described in the section below. This property is used only
if the `compile` property is not defined.
## Compile function
<pre>
function compile(tElement, tAttrs, transclude) { ... }
</pre>
Compile function deals with transforming the template DOM. Since most directives do not do
template transformation, it is not used often. Examples which require compile functions are
directives which transform template DOM such as {@link
api/ng.directive:ngRepeat ngRepeat} or load the contents
asynchronously such as {@link api/ng.directive:ngView ngView}. The
compile functions takes the following arguments.
* `tElement` - template element - The element where the directive has been declared. It is
safe to do template transformation on the element and child elements only.
* `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
between all directive compile functions. See {@link
#Attributes Attributes}
* `transclude` - A transclude linking function: `function(scope, cloneLinkingFn)`.
NOTE: The template instance and the link instance may not be the same objects if the template has
been cloned. For this reason it is not safe in the compile function to do anything other the DOM
transformation that applies to all DOM clones. Specifically, DOM listener registration should be
done in a linking function rather than in a compile function.
A compile function can have a return value which can be either a function or an object.
* returning a function - is equivalent to registering the linking function via the `link` property
of the config object when the compile function is empty.
* returning an object with function(s) registered via `pre` and `post` properties - allows you to
control when a linking function should be called during the linking phase. See info about
pre-linking and post-linking functions below.
## Linking function
<pre>
function link(scope, iElement, iAttrs, controller) { ... }
</pre>
Link function is responsible for registering DOM listeners as well as updating the DOM. It is
executed after the template has been cloned. This is where most of the directive logic will be
put.
* `scope` - {@link api/ng.$rootScope.Scope Scope} - The scope to be used by the
directive for registering {@link api/ng.$rootScope.Scope#$watch watches}.
* `iElement` - instance element - The element where the directive is to be used. It is safe to
manipulate the children of the element only in `postLink` function since the children have
already been linked.
* `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
between all directive linking functions. See {@link #Attributes Attributes}
* `controller` - a controller instance - A controller instance if at least one directive on the
element defines a controller. The controller is shared among all the directives, which allows
the directives to use the controllers as a communication channel.
### Pre-linking function
Executed before the child elements are linked. Not safe to do DOM transformation since the
compiler linking function will fail to locate the correct elements for linking.
### Post-linking function
Executed after the child elements are linked. Safe to do DOM transformation in here.
<a name="Attributes"></a>
## Attributes
The attributes object - passed as a parameter in the link() or compile() functions - is a way of
accessing:
* *normalized attribute names:* Since a directive such as 'ngBind' can be expressed in many ways
sucha s as 'ng:bind', or 'x-ng-bind', the attributes object allows for a normalize accessed to
the attributes.
* *directive inter-communication:* All directives share the same instance of the attributes
object which allows the directives to use the attributes object as inter directive
communication.
* *supports interpolation:* Interpolation attributes are assigned to the attribute object
allowing other directives to read the interpolated value.
* *observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
the only way to easily get the actual value because during the linking phase the interpolation
hasn't been evaluated yet and so the value is at this time set to `undefined`.
<pre>
function linkingFn(scope, elm, attrs, ctrl) {
// get the attribute value
console.log(attrs.ngModel);
// change the attribute
attrs.$set('ngModel', 'new value');
// observe changes to interpolated attribute
attrs.$observe('ngModel', function(value) {
console.log('ngModel has changed value to ' + value);
});
}
</pre>
# Understanding Transclusion and Scopes
It is often desirable to have reusable components. Below is a pseudo code showing how a simplified
dialog component may work.
<pre>
<div>
<button ng-click="show=true">show</button>
<dialog title="Hello {{username}}."
visible="show"
on-cancel="show = false"
on-ok="show = false; doSomething()">
Body goes here: {{username}} is {{title}}.
</dialog>
</pre>
Clicking on the "show" button will open the dialog. The dialog will have a title, which is
data bound to `username`, and it will also have a body which we would like to transclude
into the dialog.
Here is an example of what the template definition for the `dialog` widget may look like.
<pre>
<div ng-show="show()">
<h3>{{title}}</h3>
<div class="body" ng-transclude></div>
<div class="footer">
<button ng-click="onOk()">Save changes</button>
<button ng-click="onCancel()">Close</button>
</div>
</div>
</pre>
This will not render properly, unless we do some scope magic.
The first issue we have to solve is that the dialog box template expect `title` to be defined, but
the place of instantiation would like to bind to `username`. Furthermore the buttons expect `onOk`
as well as `onCancel` functions to be present in the scope. This limits the usefulness of the
widget. To solve the mapping issue we use the `locals` to create local variables which the template
expects as follows:
<pre>
scope: {
title: 'bind', // set up title to accept data-binding
onOk: 'expression', // create a delegate onOk function
onCancel: 'expression', // create a delegate onCancel function
show: 'accessor' // create a getter/setter function for visibility.
}
</pre>
Creating local properties on widget scope creates two problems:
1. isolation - if the user forgets to set `title` attribute of the dialog widget the dialog
template will bind to parent scope property. This is unpredictable and undesirable.
2. transclusion - the transcluded DOM can see the widget locals, which may overwrite the
properties which the transclusion needs for data-binding. In our example the `title`
property of the widget clobbers the `title` property of the transclusion.
To solve the issue of lack of isolation, the directive declares a new `isolated` scope. An
isolated scope does not prototypically inherit from the child scope, and therefore we don't have
to worry about accidentally clobbering any properties.
However 'isolated' scope creates a new problem: if a transcluded DOM is a child of the widget
isolated scope then it will not be able to bind to anything. For this reason the transcluded scope
is a child of the original scope, before the widget created an isolated scope for its local
variables. This makes the transcluded and widget isolated scope siblings.
This may seem as unexpected complexity, but it gives the widget user and developer the least
surprise.
Therefore the final directive definition looks something like this:
<pre>
transclude: true,
scope: {
title: 'bind', // set up title to accept data-binding
onOk: 'expression', // create a delegate onOk function
onCancel: 'expression', // create a delegate onCancel function
show: 'accessor' // create a getter/setter function for visibility.
}
</pre>
# Creating Components
It is often desirable to replace a single directive with a more complex DOM structure. This
allows the directives to become a short hand for reusable components from which applications
can be built.
Following is an example of building a reusable widget.
<doc:example module="zippyModule">

return {
restrict: 'C',
// This HTML will replace the zippy directive.
replace: true,
transclude: true,
scope: { title:'@zippyTitle' },
template: '<div>' +
'<div class="title">{{title}}</div>' +
'<div class="body" ng-transclude></div>' +
'</div>',
// The linking function will add behavior to the template
link: function(scope, element, attrs) {
// Title element
var title = angular.element(element.children()[0]),
// Opened / closed state
opened = true;
// Clicking on title should open/close the zippy
title.bind('click', toggle);
// Toggle the closed/opened state
function toggle() {
opened = !opened;
element.removeClass(opened ? 'closed' : 'opened');

@ngdoc overview
@name Developer Guide: Expressions
@description
Expressions are JavaScript-like code snippets that are usually placed in bindings such as `{{
expression }}`. Expressions are process by the {@link api/ng.$parse $parse}
service.
For example, these are all valid expressions in angular:
* `1+2`
* `3*10 | currency`
* `user.name`
## Angular Expressions vs. JS Expressions
It might be tempting to think of angular view expressions as JavaScript expressions, but that is
not entirely correct, since angular does not use a JavaScript `eval()` to evaluate expressions.
You can think of angular expressions as JavaScript expressions with following differences
differences:
* **Attribute Evaluation:** evaluation of all properties are against the scope, doing the
evaluation, unlike in JavaScript where the expressions are evaluated against the global
`window`.
* **Forgiving:** expression evaluation is forgiving to undefined and null, unlike in JavaScript,
where such evaluations generate `NullPointerExceptions`.
* **No Control Flow Statements:** you cannot do any of the following in angular expression:
conditionals, loops, or throw.
* **Filters:** you can pass result of expression evaluations through filter chains. For example
to convert date object into a local specific human-readable format.
If, on the other hand, you do want to run arbitrary JavaScript code, you should make it a
controller method and call the method. If you want to `eval()` an angular expression from
JavaScript, use the {@link api/ng.$rootScope.Scope#$eval `$eval()`} method.
## Example
<doc:example>
<doc:source>
1+2={{1+2}}
</doc:source>
<doc:scenario>
it('should calculate expression in binding', function() {
expect(binding('1+2')).toEqual('3');
});
</doc:scenario>
</doc:example>
You can try evaluating different expressions here:
<doc:example>
<doc:source>
<script>
function Cntl2($scope) {
var exprs = $scope.exprs = [];
$scope.expr = '3*10|currency';
$scope.addExp = function(expr) {
exprs.push(expr);
};
$scope.removeExp = function(index) {
exprs.splice(index, 1);
};
}
</script>
<div ng-controller="Cntl2" class="expressions">
Expression:
<input type='text' ng-model="expr" size="80"/>
<button ng-click="addExp(expr)">Evaluate</button>
<ul>
<li ng-repeat="expr in exprs">
[ <a href="" ng-click="removeExp($index)">X</a> ]
<tt>{{expr}}</tt> => <span ng-bind="$parent.$eval(expr)"></span>
</li>
</ul>
</div>
</doc:source>
<doc:scenario>
it('should allow user expression testing', function() {
element('.expressions :button').click();
var li = using('.expressions ul').repeater('li');
expect(li.count()).toBe(1);
expect(li.row(0)).toEqual(["3*10|currency", "$30.00"]);
});
</doc:scenario>
</doc:example>
# Property Evaluation
Evaluation of all properties takes place against a scope. Unlike JavaScript, where names default
to global window properties, angular expressions have to use {@link api/ng.$window
`$window`} to refer to the global `window` object. For example, if you want to call `alert()`, which is
defined on `window`, in an expression must use `$window.alert()`. This is done intentionally to
prevent accidental access to the global state (a common source of subtle bugs).
<doc:example>
<doc:source>
<script>
function Cntl1($window, $scope){
$scope.name = 'World';
$scope.greet = function() {
($window.mockWindow || $window).alert('Hello ' + $scope.name);
}
}
</script>
<div class="example2" ng-controller="Cntl1">
Name: <input ng-model="name" type="text"/>
<button ng-click="greet()">Greet</button>
</div>
</doc:source>
<doc:scenario>
it('should calculate expression in binding', function() {
var alertText;
this.addFutureAction('set mock', function($window, $document, done) {
$window.mockWindow = {
alert: function(text){ alertText = text; }
};
done();
});
element(':button:contains(Greet)').click();
expect(this.addFuture('alert text', function(done) {
done(null, alertText);
})).toBe('Hello World');
});
</doc:scenario>
</doc:example>
## Forgiving
Expression evaluation is forgiving to undefined and null. In JavaScript, evaluating `a.b.c` throws
an exception if `a` is not an object. While this makes sense for a general purpose language, the
expression evaluations are primarily used for data binding, which often look like this:
{{a.b.c}}
It makes more sense to show nothing than to throw an exception if `a` is undefined (perhaps we are
waiting for the server response, and it will become defined soon). If expression evaluation wasn't
forgiving we'd have to write bindings that clutter the code, for example: `{{((a||{}).b||{}).c}}`
Similarly, invoking a function `a.b.c()` on undefined or null simply returns undefined.
## No Control Flow Statements
You cannot write a control flow statement in an expression. The reason behind this is core to the
angular philosophy that application logic should be in controllers, not in the view. If you need a
conditional, loop, or to throw from a view expression, delegate to a JavaScript method instead.
## Filters
When presenting data to the user, you might need to convert the data from its raw format to a
user-friendly format. For example, you might have a data object that needs to be formatted
according to the locale before displaying it to the user. You can pass expressions through a chain
of filters like this:
name | uppercase
The expression evaluator simply passes the value of name to {@link
api/ng.filter:uppercase `uppercase`} filter.
Chain filters using this syntax:
value | filter1 | filter2
You can also pass colon-delimited arguments to filters, for example, to display the number 123
with 2 decimal points:
123 | number:2
# The $
You might be wondering, what is the significance of the $ prefix? It is simply a prefix that
angular uses, to differentiate its API names from others. If angular didn't use $, then evaluating
`a.length()` would return undefined because neither a nor angular define such a property.
Consider that in a future version of angular we might choose to add a length method, in which case
the behavior of the expression would change. Worse yet, you the developer could create a length
property and then we would have a collision. This problem exists because angular augments existing
objects with additional behavior. By prefixing its additions with $ we are reserving our namespace
so that angular developers and developers who use angular can develop in harmony without collisions.

@name Forms
@description
Controls (`input`, `select`, `textarea`) are a way for user to enter data.
Form is a collection of controls for the purpose of grouping related controls together.
Form and controls provide validation services, so that the user can be notified of invalid input.
This provides a better user experience, because the user gets instant feedback on how to correct the error.
Keep in mind that while client-side validation plays an important role in providing good user experience, it can easily be circumvented and thus can not be trusted.
Server-side validation is still necessary for a secure application.
# Simple form
The key directive in understanding two-way data-binding is {@link api/ng.directive:ngModel ngModel}.
The `ngModel` directive provides the two-way data-binding by synchronizing the model to the view, as well as view to the model.
In addition it provides {@link api/ng.directive:ngModel.NgModelController API} for other directives to augment its behavior.
<doc:example>
<doc:source>
<div ng-controller="Controller">
<form novalidate class="simple-form">
Name: <input type="text" ng-model="user.name" /><br />
E-mail: <input type="email" ng-model="user.email" /><br />
Gender: <input type="radio" ng-model="user.gender" value="male" />male
<input type="radio" ng-model="user.gender" value="female" />female<br />
<button ng-click="reset()">RESET</button>
<button ng-click="update(user)">SAVE</button>
</form>
<pre>form = {{user | json}}</pre>
<pre>master = {{master | json}}</pre>
</div>
<script>
function Controller($scope) {
$scope.master= {};
$scope.update = function(user) {
$scope.master= angular.copy(user);
};
$scope.reset = function() {
$scope.user = angular.copy($scope.master);
};
$scope.reset();
}
</script>
</doc:source>
</doc:example>
Note that `novalidate` is used to disable browser's native form validation.
# Using CSS classes
To allow styling of form as well as controls, `ngModel` add these CSS classes:
- `ng-valid`
- `ng-invalid`
- `ng-pristine`
- `ng-dirty`
Following example uses the CSS to display validity of each form control.
In the example both `user.name` and `user.email` are required, but are rendered with red background only when they are dirty.
This ensures that the user is not distracted with an error until after interacting with the control, and failing to satisfy its validity.
<doc:example>
<doc:source>
<div ng-controller="Controller">
<form novalidate class="css-form">
Name:
<input type="text" ng-model="user.name" required /><br />
E-mail: <input type="email" ng-model="user.email" required /><br />
Gender: <input type="radio" ng-model="user.gender" value="male" />male
<input type="radio" ng-model="user.gender" value="female" />female<br />
<button ng-click="reset()">RESET</button>
<button ng-click="update(user)">SAVE</button>
</form>
</div>
<style type="text/css">
.css-form input.ng-invalid.ng-dirty {
background-color: #FA787E;
}
.css-form input.ng-valid.ng-dirty {
background-color: #78FA89;
}
</style>
<script>
function Controller($scope) {
$scope.master= {};
$scope.update = function(user) {
$scope.master= angular.copy(user);
};
$scope.reset = function() {
$scope.user = angular.copy($scope.master);
};
$scope.reset();
}
</script>
</doc:source>
</doc:example>
# Binding to form and control state
A form is in instance of {@link api/ng.directive:form.FormController FormController}.
The form instance can optionally be published into the scope using the `name` attribute.
Similarly control is an instance of {@link api/ng.directive:ngModel.NgModelController NgModelController}.
The control instance can similarly be published into the form instance using the `name` attribute.
This implies that the internal state of both the form and the control is available for binding in the view using the standard binding primitives.
This allows us to extend the above example with these features:
- RESET button is enabled only if form has some changes
- SAVE button is enabled only if form has some changes and is valid
- custom error messages for `user.email` and `user.agree`
<doc:example>
<doc:source>
<div ng-controller="Controller">
<form name="form" class="css-form" novalidate>
Name:
<input type="text" ng-model="user.name" name="uName" required /><br />
E-mail:
<input type="email" ng-model="user.email" name="uEmail" required/><br />
<div ng-show="form.uEmail.$dirty && form.uEmail.$invalid">Invalid:
<span ng-show="form.uEmail.$error.required">Tell us your email.</span>
<span ng-show="form.uEmail.$error.email">This is not a valid email.</span>
</div>
Gender: <input type="radio" ng-model="user.gender" value="male" />male
<input type="radio" ng-model="user.gender" value="female" />female<br />

I agree: <input ng-show="user.agree" type="text" ng-model="user.agreeSign"
required /><br />
<div ng-show="!user.agree || !user.agreeSign">Please agree and sign.</div>

# Custom Validation
Angular provides basic implementation for most common html5 {@link api/ng.directive:input input}
types: ({@link api/ng.directive:input.text text}, {@link api/ng.directive:input.number number}, {@link api/ng.directive:input.url url}, {@link api/ng.directive:input.email email}, {@link api/ng.directive:input.radio radio}, {@link api/ng.directive:input.checkbox checkbox}), as well as some directives for validation (`required`, `pattern`, `minlength`, `maxlength`, `min`, `max`).
Defining your own validator can be done by defining your own directive which adds a custom validation function to the `ngModel` {@link api/ng.directive:ngModel.NgModelController controller}.
To get a hold of the controller the directive specifies a dependency as shown in the example below.
The validation can occur in two places:
* **Model to View update** -
Whenever the bound model changes, all functions in {@link api/ng.directive:ngModel.NgModelController#$formatters NgModelController#$formatters} array are pipe-lined, so that each of these functions has an opportunity to format the value and change validity state of the form control through {@link api/ng.directive:ngModel.NgModelController#$setValidity NgModelController#$setValidity}.
* **View to Model update** -
In a similar way, whenever a user interacts with a control, the controll calls {@link api/ng.directive:ngModel.NgModelController#$setViewValue NgModelController#$setViewValue}.
This in turn pipelines all functions in {@link api/ng.directive:ngModel.NgModelController#$parsers NgModelController#$parsers} array, so that each of these functions has an opportunity to convert the value and change validity state of the form control through {@link api/ng.directive:ngModel.NgModelController#$setValidity NgModelController#$setValidity}.
In the following example we create two directives.
* The first one is `integer` and it validates whether the input is a valid integer.
For example `1.23` is an invalid value, since it contains a fraction.
Note, that we unshift the array instead of pushing.
This is because we want to be first parser and consume the control string value, as we need to execute the validation function before a conversion to number occurs.
* The second directive is a `smart-float`.
It parses both `1.2` and `1,2` into a valid float number `1.2`.
Note that, we can't use input type `number` here as HTML5 browsers would not allow the user to type what it would consider an invalid number such as `1,2`.

# Implementing custom form control (using `ngModel`)
Angular implements all of the basic HTML form controls ({@link api/ng.directive:input input}, {@link api/ng.directive:select select}, {@link api/ng.directive:textarea textarea}), which should be sufficient for most cases.
However, if you need more flexibility, you can write your own form control as a directive.
In order for custom control to work with `ngModel` and to achieve two-way data-binding it needs to:
- implement `render` method, which is responsible for rendering the data after it passed the {@link api/ng.directive:ngModel.NgModelController#$formatters NgModelController#$formatters},
- call `$setViewValue` method, whenever the user interacts with the control and model needs to be updated. This is usually done inside a DOM Event listener.
See {@link guide/directive $compileProvider.directive} for more info.
The following example shows how to add two-way data-binding to contentEditable elements.

angular.module('form-example2', []).directive('contenteditable', function() {

elm.bind('blur', function() {
scope.$apply(function() {
ctrl.$setViewValue(elm.html());
});
});
// model -> view
ctrl.render = function(value) {
elm.html(value);
};
// load init value from DOM
ctrl.$setViewValue(elm.html());
}
};
});

<html xmlns:ng="http://angularjs.org">
<head>
<!--[if lte IE 8]>
<script>
document.createElement('ng-include');
document.createElement('ng-pluralize');
document.createElement('ng-view');
// Optionally these for CSS
document.createElement('ng:include');
document.createElement('ng:pluralize');
document.createElement('ng:view');
</script>
<![endif]-->
</head>
<body>
...
</body>
</html>
</pre>
The **important** parts are:
* `xmlns:ng` - *namespace* - you need one namespace for each custom tay you are planning on
using.
* `document.createElement(yourTagName)` - *creation of custom tag names* - Since this is an
issue only for older version of IE you need to load it conditionally. For each tag which does
not have namespace and which is not defined in HTML you need to pre-declare it to make IE
happy.
# Long Version
IE has an issues with element tag names which are not standard HTML tag names. These fall into two
categories, and each category has its own fix.
* If the tag name starts with `my:` prefix than it is considered an XML namespace and must
have corresponding namespace declaration on `<html xmlns:my="ignored">`
* If the tag has no `:` but it is not a standard HTML tag, then it must be pre-created using
`document.createElement('my-tag')`
* If you have are planning on styling the custom tag with CSS selectors, then it must be
pre-created using `document.createElement('my-tag')` regardless of XML namespace.
## The Good News
The good news is that these restrictions only apply to element tag names, and not to element
attribute names. So this requires no special handling in IE: `<div my-tag your:tag></div>`.
## What happens if I fail to do this?
Suppose you have HTML with unknown tag `mytag` (this could also be `my:tag` or `my-tag` with same
result):
<pre>
<html>
<body>
<mytag>some text</mytag>
</body>
</html>
</pre>
It should pares into the following DOM:
<pre>
#document
+- HTML
+- BODY
+- mytag
+- #text: some text
</pre>
The expected behavior is that the `BODY` element has a child element `mytag`, which in turn has
the text `some text`.
But this is not what IE does (if the above fixes are not included):
<pre>
#document
+- HTML
+- BODY
+- mytag
+- #text: some text
+- /mytag
</pre>
In IE, the behavior is that the `BODY` element has three children:
1. A self closing `mytag`. Example of self closing tag is `<br/>`. The trailing `/` is optional,
but the `<br>` tag is not allowed to have any children, and browsers consider `<br>some
text</br>` as three siblings not a `<br>` with `some text` as child.
2. A text node with `some text`. This should have been a child of `mytag` above, not a sibling.
3. A corrupt self closing `/mytag`. This is corrupt since element names are not allowed to have
the `/` character. Furthermore this closing element should not be part of the DOM since it is
only used to delimitate the structure of the DOM.
## CSS Styling of Custom Tag Names
The to make CSS selector work with custom elements the custom element name must be shived with the
`document.createElement('my-tag')` regardless of XML namespace.
<pre>
<html xmlns:ng="needed for ng: namespace">
<head>
<!--[if lte IE 8]>
<script>
// needed to make ng-include parse properly
document.createElement('ng-include');
// needed to enable CSS reference
document.createElement('ng:view');
</script>
<![endif]-->
<style>
ng\\:view {
display: block;
border: 1px solid red;
}
ng-include {
display: block;
border: 1px solid blue;
}
</style>
</head>
<body>
<ng:view></ng:view>
<ng-include></ng-include>
...
</body>
</html>
</pre>

@name Developer Guide: Modules
@description
# What is a Module?
Most applications have a main method which instantiates, wires, and bootstraps the application.
Angular apps don't have a main method, instead modules serve the purpose of declaratively
specifying how an application should be bootstrapped. There are several advantages to this
approach:
* The process is more declarative which is easier to understand
* In unit-testing there is no need to load all modules, which may aid in writing unit-tests.
* Additional modules can be loaded in scenario tests, which can override some of the
configuration and help end-to-end test the application
* Third party code can be packaged as reusable modules.
* The modules can be loaded in any/parallel order (due to delayed nature of module execution).
# The Basics
Ok, I'm in a hurry. How do I get a Hello World module working?
Important things to notice:
* {@link api/angular.Module Module} API
* Notice the reference to the `myApp` module in the `<html ng-app="myApp">`, it is what
bootstraps the app using your module.
<doc:example module='simpleApp'>
<doc:source>
<script>
// declare a module
var simpleAppModule = angular.module('simpleApp', []);
// configure the module.
// in this example we will create a greeting filter
simpleAppModule.filter('greet', function() {
return function(name) {
return 'Hello, ' + name + '!';
};
});
</script>
<div>
{{ 'World' | greet }}
</div>
</doc:source>
</doc:example>
# Recommended Setup
While the example above is simple, it will not scale to large applications. Instead we recommend
that you break your application to multiple modules like this:
* A service module, for service declaration
* A directive module, for directive declaration
* A filter module, for filter declaration
* And an application level module which depends on the above modules, and which has
initialization code.
The reason for this breakup is that in your tests, it is often necessary to ignore the
initialization code, which tends to be difficult to test. By putting it into a separate module it
can be easily ignored in tests. The tests can also be more focused by only loading the modules
that are relevant to tests.
The above is only a suggestion, so feel free to tailor it to your needs.
<doc:example module='xmpl'>
<doc:source>
<script>
angular.module('xmpl.service', []).
value('greeter', {
salutation: 'Hello',
localize: function(localization) {
this.salutation = localization.salutation;
},
greet: function(name) {
return this.salutation + ' ' + name + '!';
}
}).
value('user', {
load: function(name) {
this.name = name;
}
});
angular.module('xmpl.directive', []);
angular.module('xmpl.filter', []);
angular.module('xmpl', ['xmpl.service', 'xmpl.directive', 'xmpl.filter']).
run(function(greeter, user) {
// This is effectively part of the main method initialization code
greeter.localize({
salutation: 'Bonjour'
});
user.load('World');
})
// A Controller for your app
var XmplController = function($scope, greeter, user) {
$scope.greeting = greeter.greet(user.name);
}
</script>
<div ng-controller="XmplController">
{{ greeting }}!
</div>
</doc:source>
</doc:example>
# Module Loading & Dependencies
A module is a collection of configuration and run blocks which get applied to the application
during the bootstrap process. In its simplest form the module consist of collection of two kinds
of blocks:
1. **Configuration blocks** - get executed during the provider registrations and configuration
phase. Only providers and constants can be injected into configuration blocks. This is to
prevent accidental instantiation of services before they have been fully configured.
2. **Run blocks** - get executed after the injector is created and are used to kickstart the
application. Only instances and constants can be injected into run blocks. This is to prevent
further system configuration during application run time.
<pre>
angular.module('myModule', []).
config(function(injectables) { // provider-injector
// This is an example of config block.
// You can have as many of these as you want.
// You can only inject Providers (not instances)
// into the config blocks.
}).
run(function(injectables) { // instance-injector
// This is an example of a run block.
// You can have as many of these as you want.
// You can only inject instances (not Providers)
// int the run blocks
});
</pre>
## Configuration Blocks
There are some convenience methods on the module which are equivalent to the config block. For
example:
<pre>
angular.module('myModule', []).
value('a', 123).
factory('a', function() { return 123; }).
directive('directiveName', ...).
filter('filterName', ...);
// is same as
angular.module('myModule', []).
config(function($provide, $compileProvider, $filterProvider) {
$provide.value('a', 123)
$provide.factory('a', function() { return 123; })
$compileProvider.directive('directiveName', ...).
$filterProvider.register('filterName', ...);
});
</pre>
The configuration blocks get applied in the order in which they are registered. The only exception
to it are constant definitions, which are placed at the beginning of all configuration blocks.
## Run Blocks
Run blocks are the closest thing in Angular to the main method. A run block is the code which
needs to run to kickstart the application. It is executed after all of the service have been
configured and the injector has been created. Run blocks typically contain code which is hard
to unit-test, and for this reason should be declared in isolated modules, so that they can be
ignored in the unit-tests.
## Dependencies
Modules can list other modules as their dependencies. Depending on a module implies that required
module needs to be loaded before the requiring module is loaded. In other words the configuration
blocks of the required modules execute before the configuration blocks or the requiring module.
The same is true for the run blocks. Each module can only be loaded once, even if multiple other
modules require it.
## Asynchronous Loading
Modules are a way of managing $injector configuration, and have nothing to do with loading of
scripts into a VM. There are existing projects which deal with script loading, which may be used
with Angular. Because modules do nothing at load time they can be loaded into the VM in any order
and thus script loaders can take advantage of this property and parallelize the loading process.
# Unit Testing
In its simplest form a unit-test is a way of instantiating a subset of the application in test and
then applying a stimulus to it. It is important to realize that each module can only be loaded
once per injector. Typically an app has only one injector. But in tests, each test has its own
injector, which means that the modules are loaded multiple times per VM. Properly structured
modules can help with unit testing, as in this example:
In all of these examples we are going to assume this module definition:
<pre>
angular.module('greetMod', []).
factory('alert', function($window) {
return function(text) {
$window.alert(text);
}
}).
value('salutation', 'Hello').
factory('greet', function(alert, salutation) {
return function(name) {
alert(salutation + ' ' + name + '!');
}
});
</pre>
Let's write some tests:
<pre>
describe('myApp', function() {
// load the application relevant modules then load a special
// test module which overrides the $window with mock version,
// so that calling window.alert() will not block the test
// runner with a real alert box. This is an example of overriding
// configuration information in tests.
beforeEach(module('greetMod', function($provide) {
$provide.value('$window', {
alert: jasmine.createSpy('alert')
});
}));
// The inject() will create the injector and inject the greet and
// $window into the tests. The test need not concern itself with
// wiring of the application, only with testing it.
it('should alert on $window', inject(function(greet, $window) {
greet('World');
expect($window.alert).toHaveBeenCalledWith('Hello World!');
}));
// this is another way of overriding configuration in the
// tests using an inline module and inject methods.
it('should alert using the alert service', function() {
var alertSpy = jasmine.createSpy('alert');
module(function($provide) {
$provide.value('alert', alertSpy);
});
inject(function(greet) {
greet('World');
expect(alertSpy).toHaveBeenCalledWith('Hello World!');
});
});
});
</pre>

@description
# What Is Angular?
AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template
language and lets you extend HTML's syntax to express your application's components clearly and
succinctly. Out of the box, it eliminates much of the code you currently write through data
binding and dependency injection. And it all happens in JavaScript within the browser making it an
ideal partner with any server technology.
Angular is what HTML would have been had it been design for applications. HTML is a great
declarative language for static documents. It does not contain much in the way of creating
application, and as a result building web-applications is an exercise in *what do I have to do, so
that I trick the browser in to doing what I want.*
Impedance mismatch between dynamic-applications and static-documents are often solved as:
* **library** - a collection of functions which are useful when writing web apps. Your code is
in charge and it calls into the library when it sees fit. i.e.: `jQuery`
* **frameworks** - a particular implementation of a web-application, where your code fills in
the details. The framework is in charge and it calls into your code when it needs something
app specific. i.e.: `knockout`, `sproutcore`, etc...
Angular takes another approach. It attempts to minimize the impedance mismatch between document
centric HTML and what application needs by creating new HTML constructs. Angular teaches the
browser new syntax through a construct we call directives. Examples include:
* Data binding as in `{{}}`.
* DOM control structures for repeating/hiding DOM fragments.
* Support for forms and form validation.
* Attaching code-behind to DOM elements.
* Grouping of HTML into reusable components.
## End-to-end solution
Angular tries to be an end to end solution, when building a web-application. This means it is
not a single piece in an overall puzzle of building a web-application, but an end-to-end solution.
This makes Angular opinionated about how a CRUD application should be built. But while it is
opinionated, it also tries to make sure that its opinion is just a starting point, which you can
easily change. Angular comes with the following out-of-the-box:
* Everything you need to build a CRUD app in a cohesive set: Data-binding, basic templating
directives, form validation, routing, deep-linking, reusable components, dependency injection.
* Testability story: unit-testing, end-to-end testing, mocks, test harnesses.
* Seed application with directory layout and test scripts as a starting point.
## Angular Sweet Spot
Angular simplifies the application development by presenting a higher level of abstraction to the
developer. Like any abstraction, it comes at a cost of flexibility. In other words not every app
is a good fit for Angular. Angular was built for the CRUD application in mind, luckily CRUD
applications represent at least 90% of the web applications. But to understand what Angular is
good at one also has to understand when an app is not a good fit for Angular.
Games, and GUI editors are examples of very intensive and tricky DOM manipulation. These kinds of
apps are different from CRUD apps, and as a result are not a good fit for Angular. In these cases
using something closer to bare metal such as `jQuery` may be a better fit.
# An Introductory Angular Example
Below is a typical CRUD application which contains a form. The form values are validated, and
are used to compute the total, which is formatted to a particular local. These are some common
concepts which the application developer may face:
* attaching data-model to the UI.
* writing, reading and validating user input.
* computing new values based on the model.
* formatting output in a user specific locale.
<example>
<file name="script.js">
function InvoiceCntl($scope) {
$scope.qty = 1;
$scope.cost = 19.95;
}
</file>
<file name="index.html">
<div ng-controller="InvoiceCntl">
<b>Invoice:</b>
<br>
<br>
<table>
<tr><td>Quantity</td><td>Cost</td></tr>
<tr>
<td><input type="integer" min="0" ng-model="qty" required ></td>
<td><input type="number" ng-model="cost" required ></td>
</tr>
</table>
<hr>
<b>Total:</b> {{qty * cost | currency}}
</div>
</file>
<file name="scenario.js">
it('should show of angular binding', function() {
expect(binding('qty * cost')).toEqual('$19.95');
input('qty').enter('2');
input('cost').enter('5.00');
expect(binding('qty * cost')).toEqual('$10.00');
});
</file>
</example>
Try out the Live Preview above, and then let's walk through the example and describe what's going
on.
In the `<html>` tag, we specify that it is an angular
application with the `ng-app` directive. The `ng-app' will cause the angular to {@link
bootstrap auto initialize} your application.
<html ng-app>
We load the angular using the `<script>` tag:
<script src="http://code.angularjs.org/angular-?.?.?.min.js"></script>
From the `ng-model` attribute of the `<input>` tags, angular automatically sets up two-way data
binding, and we also demonstrate some easy input validation:
Quantity: <input type="integer" min="0" ng-model="qty" required >
Cost: <input type="number" ng-model="cost" required >
These input widgets look normal enough, but consider these points:
* When this page loaded, angular bound the names of the input widgets (`qty` and `cost`) to
variables of the same name. Think of those variables as the "Model" component of the
Model-View-Controller design pattern.
* Note that the HTML widget {@link api/ng.directive:input input}
has special powers. The input invalidates itself by turning red when you enter invalid data or
leave the the input fields blank. These new widget behavior make it easier to implement field
validation common in CRUD applications.
And finally, the mysterious `{{ double curly braces }}`:
Total: {{qty * cost | currency}}
This notation, `{{ _expression_ }}`, is angular markup for data-binding. The expression itself can
be a combination of both an expression and a {@link dev_guide.templates.filters filter}: `{{
expression | filter }}`. Angular provides filters for formatting display data.
In the example above, the expression in double-curly braces directs angular to "Bind the data we
got from the input widgets to the display, multiply them together, and format the resulting number
into output that looks like money."
Notice that we achieved this application behavior not by calling angular methods, nor by
implementing application specific behavior as framework. We achieved the behavior because the
browser behaved more in line what is needed for dynamic web-application rather then what is needed
for static-document. Angular has lowered the impedance mismatch to the point where no
library/framework calls are needed.
# The Zen of Angular
Angular is built around the belief that declarative code is better than imperative when it comes
to building UIs and wiring software components together, while imperative code is excellent for
expressing business logic.
* It is a very good idea to decouple DOM manipulation from app logic. This dramatically improves
the testability of the code.
* It is a really, _really_ good idea to regard app testing as equal in importance to app
writing. Testing difficulty is dramatically affected by the way the code is structured.
* It is an excellent idea to decouple the client side of an app from the server side. This
allows development work to progress in parallel, and allows for reuse of both sides.
* It is very helpful indeed if the framework guides developers through the entire journey of
building an app: from designing the UI, through writing the business logic, to testing.
* It is always good to make common tasks trivial and difficult tasks possible.
Angular frees you from the following pain:
* **Registering callbacks:** Registering callbacks clutters your code, making it hard to see the
forest for the trees. Removing common boilerplate code such as callbacks is a good thing. It
vastly reduces the amount of JavaScript coding _you_ have to do, and it makes it easier to see
what your application does.
* **Manipulating HTML DOM programmatically:** Manipulating HTML DOM is a cornerstone of AJAX
applications, but it's cumbersome and error-prone. By declaratively describing how the UI
should change as your application state changes, you are freed from low level DOM manipulation
tasks. Most applications written with angular never have to programmatically manipulate the
DOM, although you can if you want to.
* **Marshaling data to and from the UI:** CRUD operations make up the majority of AJAX
applications. The flow of marshaling data from the server to an internal object to an HTML
form, allowing users to modify the form, validating the form, displaying validation errors,
returning to an internal model, and then back to the server, creates a lot of boilerplate
code. Angular eliminates almost all of this boilerplate, leaving code that describes the
overall flow of the application rather than all of the implementation details.
* **Writing tons of initialization code just to get started:** Typically you need to write a lot
of plumbing just to get a basic "Hello World" AJAX app working. With angular you can bootstrap
your app easily using services, which are auto-injected into your application in a {@link
http://code.google.com/p/google-guice/ Guice}-like dependency-injection style. This allows you
to get started developing features quickly. As a bonus, you get full control over the
initialization process in automated tests.

@ngdoc overview
@name Developer Guide: Scopes
@description
# What are Scopes?
{@link api/ng.$rootScope.Scope scope} is an object that refers to the application
model. It is an execution context for {@link expression expressions}. Scopes are
arranged in hierarchical structure which mimic the DOM structure of the application. Scopes can
watch {@link guide/expression expressions} and propagate events.
## Scope characteristics
- Scopes provide APIs ({@link api/ng.$rootScope.Scope#$watch $watch}) to observe
model mutations.
- Scopes provide APIs ({@link api/ng.$rootScope.Scope#$apply $apply}) to
propagate any model changes through the system into the view from outside of the "Angular
realm" (controllers, services, Angular event handlers).
- Scopes can be nested to isolate application components while providing access to shared model
properties. A scope (prototypically) inherits properties from its parent scope.
- Scopes provide context against which {@link guide/expression expressions} are evaluated. For
example `{{username}}` expression is meaningless, unless it is evaluated against a specific
scope which defines the `username` property.
## Scope as Data-Model
Scope is the glue between application controller and the view. During the template {@link compiler
linking} phase the {@link api/ng.$compileProvider.directive directives} set up
{@link api/ng.$rootScope.Scope#$watch `$watch`} expressions on the scope. The
`$watch` allows the directives to be notified of property changes, which allows the directive to
render the updated value to the DOM.
Both controllers and directives have reference to the scope, but not to each other. This
arrangement isolates the controller from the directive as well as from DOM. This is an important
point since it makes the controllers view agnostic, which greatly improves the testing story of
the applications.
<example>
<file name="script.js">
function MyController($scope) {
$scope.username = 'World';
$scope.sayHello = function() {
$scope.greeting = 'Hello ' + $scope.username + '!';
};
}
</file>
<file name="index.html">
<div ng-controller="MyController">
Your name:
<input type="text" ng-model="username">
<button ng-click='sayHello()'>greet</button>
<hr>
{{greeting}}
</div>
</file>
</example>
In the above example notice that the `MyController` assigns `World` to the `username` property of
the scope. The scope then notifies the `input` of the assignment, which then renders the input
with username pre-filled. This demonstrates how a controller can write data into the scope.
Similarly the controller can assign behavior to scope as seen by the `sayHello` method, which is
invoked when the user clicks on the 'greet' button. The `sayHello` method can read the `username`
property and create a `greeting` property. This demonstrates that the properties on scope update
automatically when they are bound to HTML input widgets.
Logically the rendering of `{{greeting}}` involves:
* retrieval of the scope associated with DOM node where `{{greeting}}` is defined in template.
In this example this is the same scope as the scope which was passed into `MyController`. (We
will discuss scope hierarchies later.)
* Evaluate the `greeting` {@link guide/expression expression} against the scope retrieved above,
and assign the result to the text of the enclosing DOM element.
You can think of the scope and its properties as the data which is used to render the view. The
scope is the single source-of-truth for all things view related.
From testability, the separation of the controller and the view is desirable, because it allows us
to test the behavior without being distracted by the rendering details.
<pre>
it('should say hello', function() {
var scopeMock = {};
var cntl = new MyController(scopeMock);
// Assert that username is pre-filled
expect(scopeMock.username).toEqual('World');
// Assert that we read new username and greet
scopeMock.username = 'angular';
scopeMock.sayHello();
expect(scopeMock.greeting).toEqual('Hello angular!');
});
</pre>
## Scope Hierarchies
Each Angular application has exactly one {@link api/ng.$rootScope root scope}, but
may have several child scopes.
The application can have multiple scopes, because some {@link guide/directive directives} create
new child scopes (refer to directive documentation to see which directives create new scopes).
When new scopes are created, they are added as children of their parent scope. This creates a tree
structure which parallels the DOM where they're attached
When Angular evaluates `{{username}}`, it first looks at the scope associated with the given
element for the `username` property. If no such property is found, it searches the parent scope
and so on until the root scope is reached. In JavaScript this behavior is known as prototypical
inheritance, and child scopes prototypically inherit from their parents.
This example illustrates scopes in application, and prototypical inheritance of properties.
<example>
<file name="style.css">
/* remove .doc-example-live in jsfiddle */
.doc-example-live .ng-scope {
border: 1px dashed red;
}
</file>
<file name="script.js">
function EmployeeController($scope) {
$scope.department = 'Engineering';
$scope.employee = {
name: 'Joe the Manager',
reports: [
{name: 'John Smith'},
{name: 'Mary Run'}
]
};
}
</file>
<file name="index.html">
<div ng-controller="EmployeeController">
Manager: {{employee.name}} [ {{department}} ]<br>
Reports:
<ul>
<li ng-repeat="employee in employee.reports">
{{employee.name}} [ {{department}} ]
</li>
</ul>
<hr>
{{greeting}}
</div>
</file>
</example>
Notice that the Angular automatically places `ng-scope` class on elements where scopes are
attached. The `<style>` definition in this example highlights in red the new scope locations. The
child scopes are necessary because the repeater evaluates `{{employee.name}}` expression, but
depending on which scope the expression is evaluated it produces different result. Similarly the
evaluation of `{{department}}` prototypically inherits from root scope, as it is the only place
where the `department` property is defined.
## Retrieving Scopes from the DOM.
Scopes are attached to the DOM as `$scope` data property, and can be retrieved for debugging
purposes. (It is unlikely that one would need to retrieve scopes in this way inside the
application.) The location where the root scope is attached to the DOM is defined by the location
of {@link api/ng.directive:ngApp `ng-app`} directive. Typically
`ng-app` is placed an the `<html>` element, but it can be placed on other elements as well, if,
for example, only a portion of the view needs to be controlled by angular.
To examine the scope in the debugger:
1. right click on the element of interest in your browser and select 'inspect element'. You
should see the browser debugger with the element you clicked on highlighted.
2. The debugger allows you to access the currently selected element in the console as `$0`
variable.
3. To retrieve the associated scope in console execute: `angular.element($0).scope()`
## Scope Events Propagation
Scopes can propagate events in similar fashion to DOM events. The event can be {@link
api/ng.$rootScope.Scope#$broadcast broadcasted} to the scope children or {@link
api/ng.$rootScope.Scope#$emit emitted} to scope parents.
<example>
<file name="script.js">
function EventController($scope) {
$scope.count = 0;
$scope.$on('MyEvent', function() {
$scope.count++;
});
}
</file>
<file name="index.html">
<div ng-controller="EventController">
Root scope <tt>MyEvent</tt> count: {{count}}
<ul>
<li ng-repeat="i in [1]" ng-controller="EventController">
<button ng-click="$emit('MyEvent')">$emit('MyEvent')</button>
<button ng-click="$broadcast('MyEvent')">$broadcast('MyEvent')</button>
<br>
Middle scope <tt>MyEvent</tt> count: {{count}}
<ul>
<li ng-repeat="item in [1, 2]" ng-controller="EventController">
Leaf scope <tt>MyEvent</tt> count: {{count}}
</li>
</ul>
</li>
</ul>
</div>
</file>
</example>
## Scope Life Cycle
The normal flow of browser receiving an event is that it executes a corresponding JavaScript
callback. Once the callback completes the browser re-renders the DOM and returns to waiting for
more events.
When the browser calls into JavaScript the code executes outside they Angular execution context,
which means that Angular is unaware of model modifications. To properly process model
modifications the execution has to enter the Angular execution context using the {@link
api/ng.$rootScope.Scope#$apply `$apply`} method. Only model modifications which
execute inside the `$apply` method will be properly accounted for by Angular. For example if a
directive listens on DOM events, such as {@link
api/ng.directive:ngClick `ng-click`} it must evaluate the
expression inside the `$apply` method.
After evaluating the expression `$apply` method performs a {@link
api/ng.$rootScope.Scope#$digest `$digest`}. In $digest phase the scope examines all
of the `$watch` expressions and compares them with previous value. This dirty checking, is done
asynchronously. This means that assignment such as `$scope.username="angular"` will not
immediately cause a `$watch` to be notified, instead the `$watch` notification is delayed until
the `$digest` phase. This delay is desirable, since it coalesces multiple model updates into one
`$watch` notification as well as it guarantees that during the `$watch` notification no other
`$watch`es are running. If a `$watch` changes the value of the model, it will force additional
`$digest` cycle.
1. **Creation**
The {@link api/ng.$rootScope root scope} is created during the application
bootstrap by the {@link api/AUTO.$injector $injector}. During template
linking, some directives create new child scopes.
2. **Watcher registration**
During template linking directives register {@link
api/ng.$rootScope.Scope#$watch watches} on the scope. This watches will be
used to propagate model values to the DOM.
3. **Model mutation**
For mutations to be properly observed, you should make them only within the {@link
api/ng.$rootScope.Scope#$apply scope.$apply()}. (Angular apis do this
implicitly, so no extra `$apply` call is needed when doing synchronous work in controllers,
or asynchronous work with {@link api/ng.$http $http} or {@link
api/ng.$timeout $timeout} services.
4. **Mutation observation**
At the end `$apply`, Angular performs a {@link api/ng.$rootScope.Scope#$digest
$digest} cycle on the root scope, which then propagates throughout all child scopes. During
the `$digest` cycle, all `$watch`ed expressions or functions are checked for model mutation
and if a mutation is detected, the `$watch` listener is called.
5. **Scope destruction**
When child scopes are no longer needed, it is the responsibility of the child scope creator
to destroy them via {@link api/ng.$rootScope.Scope#$destroy scope.$destroy()}
API. This will stop propagation of `$digest` calls into the child scope and allow for memory
used by the child scope models to be reclaimed by the garbage collector.
### Scopes and Directives
During the compilation phase, the {@link compiler compiler} matches {@link
api/ng.$compileProvider.directive directives} against the DOM template. The directives
usually fall into one of two categories:
- Observing {@link api/ng.$compileProvider.directive directives}, such as
double-curly expressions `{{expression}}`, register listeners using the {@link
api/ng.$rootScope.Scope#$watch $watch()} method. This type of directive needs
to be notified whenever the expression changes so that it can update the view.
- Listener directives, such as {@link api/ng.directive:ngClick
ng-click}, register a listener with the DOM. When the DOM listener fires, the directive
executes the associated expression and updates the view using the {@link
api/ng.$rootScope.Scope#$apply $apply()} method.
When an external event (such as a user action, timer or XHR) is received, the associated {@link
expression expression} must be applied to the scope through the {@link
api/ng.$rootScope.Scope#$apply $apply()} method so that all listeners are updated
correctly.
### Directives that Create Scopes
In most cases, {@link api/ng.$compileProvider.directive directives} and scopes interact
but do not create new instances of scope. However, some directives, such as {@link
api/ng.directive:ngController ng-controller} and {@link
api/ng.directive:ngRepeat ng-repeat}, create new child scopes
and attach the child scope to the corresponding DOM element. You can retrieve a scope for any DOM
element by using an `angular.element(aDomElement).scope()` method call.
### Controllers and Scopes
Scopes and controllers interact with each other in the following situations:
- Controllers use scopes to expose controller methods to templates (see {@link
api/ng.directive:ngController ng-controller}).
- Controllers define methods (behavior) that can mutate the model (properties on the scope).
- Controllers may register {@link api/ng.$rootScope.Scope#$watch watches} on
the model. These watches execute immediately after the controller behavior executes.
See the {@link api/ng.directive:ngController ng-controller} for more
information.
### Scope `$watch` Performance Considerations
Dirty checking the scope for property changes is a common operation in Angular and for this reason
the dirty checking function must be efficient. Care should be taken that the dirty checking
function does not do any DOM access, as DOM access is orders of magnitude slower then property
access on JavaScript object.

* Double-curly binding with an expression:
As you will see shortly, everything in Angular is evaluated within a scope. We'll learn more
about this in the next steps.
Nothing here {{'yet' + '!'}}`
This line demonstrates the core feature of Angular's templating capabilities a binding, denoted
by double-curlies `{{ }}` as well as a simple expression `'yet' + '!'` used in this binding.
The binding tells Angular, that it should evaluate an expression and insert the result into the
DOM in place of the binding. Rather than a one-time insert, as we'll see in the next steps, a
binding will result in efficient continuous updates whenever the result of the expression
evaluation changes.
{@link guide/expression Angular expression} is a JavaScript-like code snippet that is
evaluated by Angular in the context of the current model scope, rather than within the scope of
the global context (`window`).
As expected, once this template is processed by Angular, the html page contains the text:
"Nothing here yet!".
## Bootstrapping AngularJS apps
Bootstrapping AngularJS apps automatically using the `ngApp` directive is very easy and suitable
for most cases. In advanced cases, such as when using script loaders, you can use
{@link guide/bootstrap imperative / manual way} to bootstrap the app.
There are 3 important things that happen during the app bootstrap:
1. The {@link api/AUTO.$injector injector} that will be used for dependency injection
within this app is created.
2. The injector will then create the {@link api/ng.$rootScope root scope} that will
become the context for the model of our application.
3. Angular will then "compile" the DOM starting at the `ngApp` root element, processing any
directives and bindings found along the way.
Once an application is bootstrapped, it will then wait for incoming browser events (such as mouse
click, key press or incoming HTTP response) that might change the model. Once such an event occurs,
Angular detects if it caused any model changes and if changes are found, Angular will reflect them
in the view by updating all of the affected bindings.
The structure of our application is currently very simple. The template contains just one directive
and one static binding, and our model is empty. That will soon change!

model, which was set up in our `PhoneListCtrl` controller.
* The curly braces around `phone.name` and `phone.snippet` are examples of {@link
guide/dev_guide.compiler.markup Angular markup}. The curly markup is shorthand for the Angular
directive {@link api/angular.directive.ng:bind ng:bind}. An `ng:bind` directive indicates a
template binding point to Angular. Binding points are locations in a template where Angular creates
data-binding between the view and the model.
In Angular, the view is a projection of the model through the HTML template. This means that
whenever the model changes, Angular refreshes the appropriate binding points, which updates the

Services are managed by angular's {@link guide/di DI subsystem}. Dependency injection
helps to make your web apps both well-structured (e.g., separate components for presentation, data,

`$http` makes an HTTP GET request to our web server, asking for `phone/phones.json` (the url is
relative to our `index.html` file). The server responds by providing the data in the json file.
(The response might just as well have been dynamically generated by a backend server. To the
browser and our app they both look the same. For the sake of simplicity we used a json file in this
tutorial.)
The `$xhr` service takes a callback as the last argument. This callback is used to process the
response. We assign the response to the scope controlled by the controller, as a model called
`phones`. Notice that angular detected the json response and parsed it for us!
The `$http` service returns a {@link api/ng.$q promise object} with a `success`
method. We call this method to handle the asynchronous response and assign the phone data to the
scope controlled by this controller, as a model called `phones`. Notice that angular detected the
json response and parsed it for us!

constructed. The dependency injector also takes care of creating any transitive dependencies the
service may have (services often depend upon other services).

constructor with some kind of fake `$http` implementation. However, the recommended (and easier) way
is to create a controller in the test environment in the same way that angular does it in the
production code behind the scenes, as follows:
<pre>
describe('PhoneCat controllers', function() {
describe('PhoneListCtrl', function() {
var scope, $browser, ctrl;
describe('PhoneListCtrl', function(){
var scope, ctrl, $httpBackend;
beforeEach(function() {
scope = angular.scope();
$browser = scope.$service('$browser');
beforeEach(inject(function(_$httpBackend_, $rootScope, $controller) {
$httpBackend = _$httpBackend_;
$httpBackend.expectGET('phones/phones.json').
respond([{name: 'Nexus S'}, {name: 'Motorola DROID'}]);
$browser.xhr.expectGET('phones/phones.json')
.respond([{name: 'Nexus S'},
{name: 'Motorola DROID'}]);
ctrl = scope.$new(PhoneListCtrl);
});
});
scope = $rootScope.$new();
ctrl = $controller(PhoneListCtrl, {$scope: scope});
}));
</pre>
Note: Because we loaded Jasmine and `angular-mocks.js` in our test environment, we got two helper
methods {@link api/angular.mock.module module} and {@link api/angular.mock.inject inject} that we'll
use to access and configure the injector.
We created the controller in the test environment, as follows:
* We created a root scope object by calling `angular.scope()`
* We used the `inject` helper method to inject instances of
{@link api/ng.$rootScope $rootScope},
{@link api/ng.$controller $controller} and
{@link api/ng.$httpBackend $httpBackend} services into the Jasmine's `beforeEach`
function. These instances come from an injector which is recreated from scratch for every single
test. This guarantees that each test starts from a well known starting point and each test is
isolated from the work done in other tests.
* We called `scope.$new(PhoneListCtrl)` to get angular to create the child scope associated with
the `PhoneListCtrl` controller
* We created a new scope for our controller by calling `$rootScope.$new()`
Because our code now uses the `$xhr` service to fetch the phone list data in our controller, before
* We called `scope.$new(PhoneListCtrl)` to get Angular to create the child scope associated with
the `PhoneListCtrl` controller.
Because our code now uses the `$http` service to fetch the phone list data in our controller, before
we create the `PhoneListCtrl` child scope, we need to tell the testing harness to expect an
incoming request from the controller. To do this we:
* Use the {@link api/angular.scope.$service `$service`} method to retrieve the `$browser` service,
a service that angular uses to represent various browser APIs. In tests, angular automatically uses
a mock version of this service that allows you to write tests without having to deal with these
native APIs and the global state associated with them.
* Request `$httpBackend` service to be injected into our `beforeEach` function. This is a mock
mock version of the service that in production environment facilitates all XHR and JSONP requests.
The mock version of this service allows you to write tests without having to deal with
native APIs and the global state associated with them — both of which make testing a nightmare.
* Use the `$browser.xhr.expectGET` method to train the `$browser` object to expect an incoming HTTP
request and tell it what to respond with. Note that the responses are not returned before we call
the `$browser.xhr.flush` method.
* Use the `$httpBackend.expectGET` method to train the `$httpBackend` service to expect an incoming
HTTP request and tell it what to respond with. Note that the responses are not returned until we call
the `$httpBackend.flush` method.
Now, we will make assertions to verify that the `phones` model doesn't exist on the scope, before
the response is received:
<pre>
it('should create "phones" model with 2 phones fetched from xhr', function() {
expect(ctrl.phones).toBeUndefined();
$browser.xhr.flush();
expect(scope.phones).toBeUndefined();
$httpBackend.flush();
expect(ctrl.phones).toEqual([{name: 'Nexus S'},
expect(scope.phones).toEqual([{name: 'Nexus S'},
{name: 'Motorola DROID'}]);
});
</pre>
* We flush the xhr queue in the browser by calling `$browser.xhr.flush()`. This causes the callback
we passed into the `$xhr` service to be executed with the trained response.
* We flush the request queue in the browser by calling `$httpBackend.flush()`. This causes the
promise returned by the `$http` service to be resolved with the trained response.
* We make the assertions, verifying that the phone model now exists on the scope.

## Controllers
### A Note About DI, Injector and Providers
__`app/js/controller.js`:__
As you noticed the dependency injection is the core feature of AngularJS, so it's important for you
to understand a thing or two about how it works.
When the application bootstraps, Angular creates an injector that will be used for all DI stuff in
this app. The injector itself doesn't know anything about what `$http` or `$route` services do, in
fact it doesn't even know about the existence of these services unless it is configured with proper
module definitions. The sole responsibilities of the injector are to load specified module
definition(s), register all service providers defined in these modules and when asked inject
a specified function with dependencies (services) that it lazily instantiates via their providers.
Providers are objects that provide (create) instances of services and expose configuration apis
that can be used to control the creation and runtime behavior of a service. In case of the `$route`
service, the `$routeProvider` exposes apis that allow you to define routes for your application.
Angular modules solve the problem of removing global state from the application and provide a way
of configuring the injector. As opposed to AMD or require.js modules, Angular modules don't try to
solve the problem of script load ordering or lazy script fetching. These goals are orthogonal and
both module systems can live side by side and fulfil their goals.

We created a new controller called `PhoneCatCtrl`. We declared its dependency on the `$route`
service and used this service to declare that our application consists of two different views:
In order to configure our application with routes, we need to create a module for our application.
We call this module `phonecatApp` and using the `config` api we request the `$routeProvider` to be
injected into our config function and use `$routeProvider.when` api to define our routes.
Note that during the injector configuration phase, the providers can be injected as well, but they
will not be available for injection once the injector is created and starts creating service
instances.
