@fullName Unstable `$onChanges` hooks
|
|
@description
|
|
|
|
This error occurs when the application's model becomes unstable because some `$onChanges` hooks are causing updates which then trigger
|
|
further calls to `$onChanges` that can never complete.
|
|
AngularJS detects this situation and prevents an infinite loop from causing the browser to become unresponsive.
|
|
|
|
For example, the situation can occur by setting up a `$onChanges()` hook which triggers an event on the component, which subsequently
|
|
triggers the component's bound inputs to be updated:
|
|
|
|
```html
|
|
<c1 prop="a" on-change="a = -a"></c1>
|
|
```
|
|
|
|
```js
|
|
function Controller1() {}
|
|
Controller1.$onChanges = function() {
|
|
this.onChange();
|
|
};
|
|
|
|
mod.component('c1', {
|
|
controller: Controller1,
|
|
bindings: {'prop': '<', onChange: '&'}
|
|
}
|
|
```
|
|
|
|
The maximum number of allowed iterations of the `$onChanges` hooks is controlled via TTL setting which can be configured via
|
|
{@link ng.$compileProvider#onChangesTtl `$compileProvider.onChangesTtl`}.
