[#15301](https://github.com/angular/angular.js/issues/15301))
## Breaking Changes
### **jqLite** due to:
- **[b7d396](https://github.com/angular/angular.js/commit/b7d396b8b6e8f27a1f4556d58fc903321e8d532a)**: make removeData() not remove event handlers
Before this commit `removeData()` invoked on an element removed its event
handlers as well. If you want to trigger a full cleanup of an element, change:
```js
elem.removeData();
```
to:
```js
angular.element.cleanData(elem);
```
In most cases, though, cleaning up after an element is supposed to be done
only when it's removed from the DOM as well; in such cases the following:
```js
elem.remove();
```
will remove event handlers as well.
### **$cookies** due to:
- **[73c646](https://github.com/angular/angular.js/commit/73c6467f1468353215dc689c019ed83aa4993c77)**: remove the deprecated $cookieStore factory
The $cookieStore has been removed. Migrate to the $cookies service. Note that
for object values you need to use the `putObject` & `getObject` methods as
`get`/`put` will not correctly save/retrieve them.
Before:
```js
$cookieStore.put('name', {key: 'value'});
$cookieStore.get('name'); // {key: 'value'}
$cookieStore.remove('name');
```
After:
```js
$cookies.putObject('name', {key: 'value'});
$cookies.getObject('name'); // {key: 'value'}
$cookies.remove('name');
```
### **$resource** due to:
- **[ea0585](https://github.com/angular/angular.js/commit/ea0585773bb93fd891576e2271254a17e15f1ddd)**: fix interceptors and success/error callbacks
If you are not using `success` or `error` callbacks with `$resource`,
your app should not be affected by this change.
If you are using `success` or `error` callbacks (with or without
response interceptors), one (subtle) difference is that throwing an
error inside the callbacks will not propagate to the returned
`$promise`. Therefore, you should try to use the promises whenever
possible. E.g.:
```js
// Avoid
User.query(function onSuccess(users) { throw new Error(); }).
$promise.
catch(function onError() { /* Will not be called. */ });
// Prefer
User.query().
$promise.
then(function onSuccess(users) { throw new Error(); }).
catch(function onError() { /* Will be called. */ });
```
Finally, if you are using `success` or `error` callbacks with response
interceptors, the callbacks will now always run _after_ the interceptors
(and wait for them to resolve in case they return a promise).
Previously, the `error` callback was called before the `responseError`
interceptor and the `success` callback was synchronously called after
the `response` interceptor. E.g.:
```js
var User = $resource('/api/users/:id', {id: '@id'}, {
get: {
method: 'get',
interceptor: {
response: function(response) {
console.log('responseInterceptor-1');
return $timeout(1000).then(function() {
console.log('responseInterceptor-2');
return response.resource;
});
},
responseError: function(response) {
console.log('responseErrorInterceptor-1');
return $timeout(1000).then(function() {
console.log('responseErrorInterceptor-2');
return $q.reject('Ooops!');
});
}
}
}
});
var onSuccess = function(value) { console.log('successCallback', value); };
var onError = function(error) { console.log('errorCallback', error); };
// Assuming the following call is successful...
User.get({id: 1}, onSuccess, onError);
// Old behavior:
// responseInterceptor-1
// successCallback, {/* Promise object */}
// responseInterceptor-2
// New behavior:
// responseInterceptor-1
// responseInterceptor-2
// successCallback, {/* User object */}
// Assuming the following call returns an error...
User.get({id: 2}, onSuccess, onError);
// Old behavior:
// errorCallback, {/* Response object */}
// responseErrorInterceptor-1
// responseErrorInterceptor-2
// New behavior:
// responseErrorInterceptor-1
// responseErrorInterceptor-2
// errorCallback, Ooops!
```
- **[240a3d](https://github.com/angular/angular.js/commit/240a3ddbf12a9bb79754031be95dae4b6bd2dded)**: add support for `request` and `requestError` interceptors (#15674)
Previously, calling a `$resource` method would synchronously call
`$http`. Now, it will be called asynchronously (regardless if a
`request`/`requestError` interceptor has been defined.
This is not expected to affect applications at runtime, since the
overall operation is asynchronous already, but may affect assertions in
tests. For example, if you want to assert that `$http` has been called
with specific arguments as a result of a `$resource` call, you now need
to run a `$digest` first, to ensure the (possibly empty) request
interceptor promise has been resolved.
Before:
```js
it('...', function() {
$httpBackend.expectGET('/api/things').respond(...);
var Things = $resource('/api/things');
Things.query();
expect($http).toHaveBeenCalledWith(...);
});
```
After:
```js
it('...', function() {
$httpBackend.expectGET('/api/things').respond(...);
var Things = $resource('/api/things');
Things.query();
$rootScope.$digest();
expect($http).toHaveBeenCalledWith(...);
});
```
### **$templateRequest**:
- due to **[c617d6](https://github.com/angular/angular.js/commit/c617d6dceee5b000bfceda44ced22fc16b48b18b)**: give tpload error the correct namespace
Previously the `tpload` error was namespaced to `$compile`. If you have
code that matches errors of the form `[$compile:tpload]` it will no
longer run. You should change the code to match
`[$templateRequest:tpload]`.
- due to **([fb0099](https://github.com/angular/angular.js/commit/fb00991460cf69ae8bc7f1f826363d09c73c0d5e)**: always return the template that is stored in the cache
The service now returns the result of `$templateCache.put()` when making a server request to the
template. Previously it would return the content of the response directly.
This now means if you are decorating `$templateCache.put()` to manipulate the template, you will
now get this manipulated result also on the first `$templateRequest` rather than only on subsequent
calls (when the template is retrived from the cache).
In practice this should not affect any apps, as it is unlikely that they rely on the template being
different in the first and subsequent calls.
### **$animate** due to:
- **[16b82c](https://github.com/angular/angular.js/commit/16b82c6afe0ab916fef1d6ca78053b00bf5ada83)**: let cancel() reject the runner promise
$animate.cancel(runner) now rejects the underlying
promise and calls the catch() handler on the runner
returned by $animate functions (enter, leave, move,
addClass, removeClass, setClass, animate).
Previously it would resolve the promise as if the animation
had ended successfully.
Example:
```js
var runner = $animate.addClass('red');
runner.then(function() { console.log('success')});
runner.catch(function() { console.log('cancelled')});
runner.cancel();
```
Pre-1.7.0, this logs 'success', 1.7.0 and later it logs 'cancelled'.
To migrate, add a catch() handler to your animation runners.
### **angular.isArray** due to:
- **[e3ece2](https://github.com/angular/angular.js/commit/e3ece2fad9e1e6d47b5f06815ff186d7e6f44948)**: support Array subclasses in `angular.isArray()`
Previously, `angular.isArray()` was an alias for `Array.isArray()`.
Therefore, objects that prototypally inherit from `Array` where not
considered arrays. Now such objects are considered arrays too.
This change affects several other methods that use `angular.isArray()`
under the hood, such as `angular.copy()`, `angular.equals()`,
`angular.forEach()`, and `angular.merge()`.
This in turn affects how dirty checking treats objects that prototypally
inherit from `Array` (e.g. MobX observable arrays). AngularJS will now
be able to handle these objects better when copying or watching.
### **$sce** due to:
- **[1e9ead](https://github.com/angular/angular.js/commit/1e9eadcd72dbbd5c67dae8328a63e535cfa91ff9)**: handle URL sanitization through the `$sce` service
If you use `attrs.$set` for URL attributes (a[href] and img[src]) there will no
longer be any automated sanitization of the value. This is in line with other
programmatic operations, such as writing to the innerHTML of an element.
If you are programmatically writing URL values to attributes from untrusted
input then you must sanitize it yourself. You could write your own sanitizer or copy
the private `$$sanitizeUri` service.
Note that values that have been passed through the `$interpolate` service within the
`URL` or `MEDIA_URL` will have already been sanitized, so you would not need to sanitize
these values again.
### **orderBy** due to:
- **[1d8046](https://github.com/angular/angular.js/commit/1d804645f7656d592c90216a0355b4948807f6b8)**: consider `null` and `undefined` greater than other values
When using `orderBy` to sort arrays containing `null` values, the `null` values
will be considered "greater than" all other values, except for `undefined`.
Previously, they were sorted as strings. This will result in different (but more
intuitive) sorting order.
Before:
```js
orderByFilter(['a', undefined, 'o', null, 'z']);
//--> 'a', null, 'o', 'z', undefined
```
After:
```js
orderByFilter(['a', undefined, 'o', null, 'z']);
//--> 'a', 'o', 'z', null, undefined
```
### **ngScenario** due to:
- **[0cd392](https://github.com/angular/angular.js/commit/0cd39217828b0ad53eaf731576af17d66c18ff60)**: completely remove the angular scenario runner
The angular scenario runner end-to-end test framework has been
removed from the project and will no longer be available on npm
or bower starting with 1.7.0.
It was deprecated and removed from the documentation in 2014.
Applications that still use it should migrate to
[Protractor](http://www.protractortest.org).
Technically, it should also be possible to continue using an
older version of the scenario runner, as the underlying APIs have
not changed. However, we do not guarantee future compatibility.
### **form** due to:
- **[223de5](https://github.com/angular/angular.js/commit/223de59e988dc0cc8b4ec3a045b7c0735eba1c77)**: set $submitted to true on child forms when parent is submitted
Forms will now set $submitted on child forms when they are submitted.
For example:
```
<form name="parentform" ng-submit="$ctrl.submit()">
<ng-form name="childform">
<input type="text" name="input" ng-model="my.model" />
</ng-form>
<input type="submit" />
</form>
```
Submitting this form will set $submitted on "parentform" and "childform".
Previously, it was only set on "parentform".
This change was introduced because mixing form and ngForm does not create
logically separate forms, but rather something like input groups.
Therefore, child forms should inherit the submission state from their parent form.
### **ngAria** due to:
- **[6d5ef3](https://github.com/angular/angular.js/commit/6d5ef34fc6a974cde73157ba94f9706723dd8f5b)**: do not set aria attributes on input[type="hidden"]
ngAria no longer sets aria-* attributes on input[type="hidden"] with ngModel.
This can affect apps that test for the presence of aria attributes on hidden inputs.
To migrate, remove these assertions.
In actual apps, this should not have a user-facing effect, as the previous behavior
was incorrect, and the new behavior is correct for accessibility.
### **ngModel, input** due to:
- **[74b04c](https://github.com/angular/angular.js/commit/74b04c9403af4fc7df5b6420f22c9f45a3e84140)**: improve handling of built-in named parsers
*Custom* parsers that fail to parse on input types "email", "url", "number", "date", "month",
"time", "datetime-local", "week", do no longer set `ngModelController.$error[inputType]`, and
the `ng-invalid-[inputType]` class. Also, custom parsers on input type "range" do no
longer set `ngModelController.$error.number` and the `ng-invalid-number` class.
Instead, any custom parsers on these inputs set `ngModelController.$error.parse` and
`ng-invalid-parse`. This change was made to make distinguishing errors from built-in parsers
and custom parsers easier.
### **ngModelOptions** due to:
- **[55ba44](https://github.com/angular/angular.js/commit/55ba44913e02650b56410aa9ab5eeea5d3492b68)**: add debounce catch-all + allow debouncing 'default' only
the 'default' key in 'debounce' now only debounces the default event, i.e. the event
that is added as an update trigger by the different input directives automatically.
Previously, it also applied to other update triggers defined in 'updateOn' that
did not have a corresponding key in the 'debounce'.
This behavior is now supported via a special wildcard / catch-all key: '*'.
See the following example:
Pre-1.7:
'mouseup' is also debounced by 500 milliseconds because 'default' is applied:
```
ng-model-options="{
updateOn: 'default blur mouseup',
debounce: { 'default': 500, 'blur': 0 }
}
```
1.7:
The pre-1.7 behavior can be re-created by setting '*' as a catch-all debounce value:
```
ng-model-options="{
updateOn: 'default blur mouseup',
debounce: { '*': 500, 'blur': 0 }
}
```
In contrast, when only 'default' is used, 'blur' and 'mouseup' are not debounced:
```
ng-model-options="{
updateOn: 'default blur mouseup',
debounce: { 'default': 500 }
}
```
### **input\[number\]** due to:
- **[aa3f95](https://github.com/angular/angular.js/commit/aa3f951330ec7b10b43ea884d9b5754e296770ec)**: validate min/max against viewValue
`input[type=number]` with `ngModel` now validates the input for the `max`/`min` restriction against
the `ngModelController.$viewValue` instead of against the `ngModelController.$modelValue`.
This affects apps that use `$parsers` or `$formatters` to transform the input / model value.
If you rely on the $modelValue validation, you can overwrite the `min`/`max` validator from a custom directive, as seen in the following example directive definition object:
```
{
restrict: 'A',
require: 'ngModel',
link: function(scope, element, attrs, ctrl) {
var maxValidator = ctrl.$validators.max;
ctrk.$validators.max = function(modelValue, viewValue) {
return maxValidator(modelValue, modelValue);
};
}
}
```
### **input** due to:
- **[656c8f](https://github.com/angular/angular.js/commit/656c8fa8f23b1277cc5c214c4d0237f3393afa1e)**: listen on "change" instead of "click" for radio/checkbox ngModels
`input[radio]` and `input[checkbox]` now listen to the "change" event instead of the "click" event.
Most apps should not be affected, as "change" is automatically fired by browsers after "click"
happens.
Two scenarios might need migration:
- Custom click events:
Before this change, custom click event listeners on radio / checkbox would be called after the
input element and `ngModel` had been updated, unless they were specifically registered before
the built-in click handlers.
After this change, they are called before the input is updated, and can call event.preventDefault()
to prevent the input from updating.
If an app uses a click event listener that expects ngModel to be updated when it is called, it now
needs to register a change event listener instead.
- Triggering click events:
Conventional trigger functions:
The change event might not be fired when the input element is not attached to the document. This
can happen in **tests** that compile input elements and
trigger click events on them. Depending on the browser (Chrome and Safari) and the trigger method,
the change event will not be fired when the input isn't attached to the document.
Before:
```js
it('should update the model', inject(function($compile, $rootScope) {
var inputElm = $compile('<input type="checkbox" ng-model="checkbox" />')($rootScope);
inputElm[0].click(); // Or different trigger mechanisms, such as jQuery.trigger()
expect($rootScope.checkbox).toBe(true);
});
```
With this patch, `$rootScope.checkbox` might not be true, because the click event
hasn't triggered the change event. To make the test, work append the inputElm to the app's
`$rootElement`, and the `$rootElement` to the `$document`.
After:
```js
it('should update the model', inject(function($compile, $rootScope, $rootElement, $document) {
var inputElm = $compile('<input type="checkbox" ng-model="checkbox" />')($rootScope);
$rootElement.append(inputElm);
$document.append($rootElement);
inputElm[0].click(); // Or different trigger mechanisms, such as jQuery.trigger()
expect($rootScope.checkbox).toBe(true);
});
```
`triggerHandler()`:
If you are using this jQuery / jqLite function on the input elements, you don't have to attach
the elements to the document, but instead change the triggered event to "change". This is because
`triggerHandler(event)` only triggers the exact event when it has been added by jQuery / jqLite.
### **ngStyle** due to:
- **[15bbd3](https://github.com/angular/angular.js/commit/15bbd3e18cd89b91f7206a06c73d40e54a8a48a0)**: use $watchCollection
Previously the use of deep watch by ng-style would trigger styles to be
re-applied when nested state changed. Now only changes to direct
properties of the watched object will trigger changes.
### **$compile** due to:
- **[38f8c9](https://github.com/angular/angular.js/commit/38f8c97af74649ce224b6dd45f433cc665acfbfb)**: remove the preAssignBindingsEnabled flag
Previously, the `$compileProvider.preAssignBindingsEnabled` flag was supported.
The flag controlled whether bindings were available inside the controller
constructor or only in the `$onInit` hook. The bindings are now no longer
available in the constructor.
To migrate your code:
1. If you haven't invoked `$compileProvider.preAssignBindingsEnabled()` you
don't have to do anything to migrate.
2. If you specified `$compileProvider.preAssignBindingsEnabled(false)`, you
can remove that statement - since AngularJS 1.6.0 this is the default so your
app should still work even in AngularJS 1.6 after such removal. Afterwards,
migrating to AngularJS 1.7.0 shouldn't require any further action.
3. If you specified `$compileProvider.preAssignBindingsEnabled(true)` you need
to first migrate your code so that the flag can be flipped to `false`. The
instructions on how to do that are available in the "Migrating from 1.5 to 1.6"
guide:
https://docs.angularjs.org/guide/migration#migrating-from-1-5-to-1-6
Afterwards, remove the `$compileProvider.preAssignBindingsEnabled(true)`
statement.
- **[6ccbfa](https://github.com/angular/angular.js/commit/6ccbfa65d60a3dc396d0cf6da21b993ad74653fd)**: lower the `xlink:href` security context for SVG's `a` and `image` elements
In the unlikely case that an app relied on RESOURCE_URL whitelisting for the
purpose of binding to the `xlink:href` property of SVG's `<a>` or `<image>`
elements and if the values do not pass the regular URL sanitization, they will
break.
To fix this you need to ensure that the values used for binding to the affected
`xlink:href` contexts are considered safe URLs, e.g. by whitelisting them in
`$compileProvider`'s `aHrefSanitizationWhitelist` (for `<a>` elements) or
`imgSrcSanitizationWhitelist` (for `<image>` elements).
- **[fd4f01](https://github.com/angular/angular.js/commit/fd4f0111188b62773b99ab6eab38b4d2b5d8d727)**: do not use deepWatch in literal one-way bindings
Previously when a literal value was passed into a directive/component via
one-way binding it would be watched with a deep watcher.
For example, for `<my-component input="[a]">`, a new instance of the array
would be passed into the directive/component (and trigger $onChanges) not
only if `a` changed but also if any sub property of `a` changed such as
`a.b` or `a.b.c.d.e` etc.
This also means a new but equal value for `a` would NOT trigger such a
change.
Now literal values use an input-based watch similar to other directive/component
one-way bindings. In this context inputs are the non-constant parts of the
literal. In the example above the input would be `a`. Changes are only
triggered when the inputs to the literal change.
- **[1cf728](https://github.com/angular/angular.js/commit/1cf728e209a9e0016068fac2769827e8f747760e)**: add `base[href]` to the list of RESOURCE_URL context attributes
Previously, `<base href="{{ $ctrl.baseUrl }}" />` would not require `baseUrl` to
be trusted as a RESOURCE_URL. Now, `baseUrl` will be sent to `$sce`'s
RESOURCE_URL checks. By default, it will break unless `baseUrl` is of the same
origin as the application document.
Refer to the
[`$sce` API docs](https://code.angularjs.org/snapshot/docs/api/ng/service/$sce)
for more info on how to trust a value in a RESOURCE_URL context.
Also, concatenation in trusted contexts is not allowed, which means that the
following won't work: `<base href="/something/{{ $ctrl.partialPath }}" />`.
Either construct complex values in a controller (recommended):
```js
this.baseUrl = '/something/' + this.partialPath;
```
```html
<base href="{{ $ctrl.baseUrl }}" />
```
Or use string concatenation in the interpolation expression (not recommended
except for the simplest of cases):
```html
<base href="{{ '/something/' + $ctrl.partialPath }}" />
```
### **ngTouch** due to:
- **[11d9ad](https://github.com/angular/angular.js/commit/11d9ad1eb25eaf5967195e424108207427835d50)**: remove ngClick override, `$touchProvider`, and `$touch`
The `ngClick` directive from the ngTouch module has been removed, and with it the
corresponding `$touchProvider` and `$touch` service.
If you have included ngTouch v1.5.0 or higher in your application, and have not
changed the value of `$touchProvider.ngClickOverrideEnabled()`, or injected and used the `$touch`
service, then there are no migration steps for your code. Otherwise you must remove references to
the provider and service.
The `ngClick` override directive had been deprecated and by default disabled since v1.5.0,
because of buggy behavior in edge cases, and a general trend to avoid special touch based
overrides of click events. In modern browsers, it should not be necessary to use a touch override
library:
- Chrome, Firefox, Edge, and Safari remove the 300ms delay when
`<meta name="viewport" content="width=device-width">` is set.
- Internet Explorer 10+, Edge, Safari, and Chrome remove the delay on elements that have the
`touch-action` css property is set to `manipulation`.

### **Angular** due to:
- **[1daa4f](https://github.com/angular/angular.js/commit/1daa4f2231a89ee88345689f001805ffffa9e7de)**: remove `angular.lowercase` and `angular.uppercase`
The helper functions `angular.lowercase` `and angular.uppercase` have
been removed.
These functions have been deprecated since 1.5.0. They are internally
used, but should not be exposed as they contain special locale handling
(for Turkish) to maintain internal consistency regardless of user-set locale.
Developers should generally use the built-ins `toLowerCase` and `toUpperCase`
or `toLocaleLowerCase` and `toLocaleUpperCase` for special cases.
Further, we generally discourage using the angular.x helpers in application code.
### **$controller** due to:
- **[e269c1](https://github.com/angular/angular.js/commit/e269c14425a3209040f65c022658770e00a36f16)**: remove instantiating controllers defined on window
The option to instantiate controllers from constructors on the global `window` object
has been removed. Likewise, the deprecated `$controllerProvider.allowGlobals()`
method that could enable this behavior, has been removed.
This behavior had been deprecated since AngularJS v1.3.0, because polluting the global scope
is bad. To migrate, remove the call to $controllerProvider.allowGlobals() in the config, and
register your controller via the Module API or the $controllerProvider, e.g.
```
angular.module('myModule', []).controller('myController', function() {...});
angular.module('myModule', []).config(function($controllerProvider) {
$controllerProvider.register('myController', function() {...});
});
```
### **$rootScope** due to:
- **([c2b8fa](https://github.com/angular/angular.js/commit/c2b8fab0a480204374d561d6b9b3d47347ac5570))**: provide correct value of one-time bindings in watchGroup
Previously when using `$watchGroup` the entries in `newValues` and
`oldValues` represented the *most recent change of each entry*.
Now the entries in `oldValues` will always equal the `newValues` of the previous
call of the listener. This means comparing the entries in `newValues` and
`oldValues` can be used to determine which individual expressions changed.
For example `$scope.$watchGroup(['a', 'b'], fn)` would previously:
| Action | newValue | oldValue |
|----------|------------|------------|
| (init) | [undefined, undefined] | [undefined, undefined] |
| `a=1` | [1, undefined] | [undefined, undefined] |
| `a=2` | [2, undefined] | [1, undefined] |
| `b=3` | [2, 3] | [1, undefined] |
Now the `oldValue` will always equal the previous `newValue`:
| Action | newValue | oldValue |
|----------|------------|------------|
| (init) | [undefined, undefined] | [undefined, undefined] |
| `a=1` | [1, undefined] | [undefined, undefined] |
| `a=2` | [2, undefined] | [1, undefined] |
| `b=3` | [2, 3] | [2, undefined] |
Note the last call now shows `a === 2` in the `oldValues` array.
This also makes the `oldValue` of one-time watchers more clear. Previously
the `oldValue` of a one-time watcher would remain `undefined` forever. For
example `$scope.$watchGroup(['a', '::b'], fn)` would previously:
| Action | newValue | oldValue |
|----------|------------|------------|
| (init) | [undefined, undefined] | [undefined, undefined] |
| `a=1` | [1, undefined] | [undefined, undefined] |
| `b=2` | [1, 2] | [undefined, undefined] |
| `a=b=3` | [3, 2] | [1, undefined] |
Where now the `oldValue` will always equal the previous `newValue`:
| Action | newValue | oldValue |
|----------|------------|------------|
| (init) | [undefined, undefined] | [undefined, undefined] |
| `a=1` | [1, undefined] | [undefined, undefined] |
| `b=2` | [1, 2] | [1, undefined] |
| `a=b=3` | [3, 2] | [1, 2] |
