<div><div class="nganimate-page"><h2>ngAnimate</h2>
<p>The ngAnimate module is an optional module that comes packed with AngularJS that can be included within an AngularJS
application to provide support for CSS and JavaScript animation hooks.</p>
<p>To make use of animations with AngularJS, the <code>angular-animate.js</code> JavaScript file must be included into your application
and the <code>ngAnimate</code> module must be included as a dependency.</p>
<pre class="prettyprint linenums">
angular.module('App', ['ngAnimate']);
</pre>
<p>Then, to see animations in action, all that is required is to define the appropriate CSS classes
or to register a JavaScript animation via the $animation service. The directives that support animation automatically are:
<code>ngRepeat</code>, <code>ngInclude</code>, <code>ngSwitch</code>, <code>ngShow</code>, <code>ngHide</code> and <code>ngView</code>. Custom directives can take advantage of animation
by using the <code>$animate</code> service.</p>
<p>Below is a more detailed breakdown of the supported animation events provided by pre-existing ng directives:</p>
<table>
<thead>
<tr>
<th>Directive</th>
<th>Supported Animations</th>
</tr>
</thead>
<tbody>
<tr>
<td><a href="api/ng.directive:ngRepeat#animations"><code>ngRepeat</code></a></td>
<td>enter, leave and move</td>
</tr>
<tr>
<td><a href="api/ngRoute.directive:ngView#animations">ngView</a></td>
<td>enter and leave</td>
</tr>
<tr>
<td><a href="api/ng.directive:ngInclude#animations"><code>ngInclude</code></a></td>
<td>enter and leave</td>
</tr>
<tr>
<td><a href="api/ng.directive:ngSwitch#animations"><code>ngSwitch</code></a></td>
<td>enter and leave</td>
</tr>
<tr>
<td><a href="api/ng.directive:ngIf#animations"><code>ngIf</code></a></td>
<td>enter and leave</td>
</tr>
<tr>
<td><a href="api/ng.directive:ngShow#animations"><code>ngClass</code></a></td>
<td>add and remove</td>
</tr>
<tr>
<td><a href="api/ng.directive:ngShow#animations"><code>ngShow &amp; ngHide</code></a></td>
<td>add and remove (the ng-hide class value)</td>
</tr>
</tbody>
</table>
<p>You can find out more information about animations upon visiting each directive page.</p>
<p>Below is an example of how to apply animations to a directive that supports animation hooks:</p>
<pre class="prettyprint linenums">
&lt;style type="text/css"&gt;
.slide.ng-enter &gt; div,
.slide.ng-leave &gt; div {
-webkit-transition:0.5s linear all;
-moz-transition:0.5s linear all;
-o-transition:0.5s linear all;
transition:0.5s linear all;
}
.slide.ng-enter { } /&#42; starting animations for enter &#42;/
.slide.ng-enter-active { } /&#42; terminal animations for enter &#42;/
.slide.ng-leave { } /&#42; starting animations for leave &#42;/
.slide.ng-leave-active { } /&#42; terminal animations for leave &#42;/
&lt;/style&gt;
&lt;!--
the animate service will automatically add .ng-enter and .ng-leave to the element
to trigger the CSS transition/animations
--&gt;
&lt;ANY class="slide" ng-include="..."&gt;&lt;/ANY&gt;
</pre>
<p>Keep in mind that if an animation is running, any child elements cannot be animated until the parent element&#39;s
animation has completed.</p>
<p><h3>CSS-defined Animations</h2>
The animate service will automatically apply two CSS classes to the animated element and these two CSS classes
are designed to contain the start and end CSS styling. Both CSS transitions and keyframe animations are supported
and can be used to play along with this naming structure.</p>
<p>The following code below demonstrates how to perform animations using <strong>CSS transitions</strong> with Angular:</p>
<pre class="prettyprint linenums">
&lt;style type="text/css"&gt;
/&#42;
The animate class is apart of the element and the ng-enter class
is attached to the element once the enter animation event is triggered
&#42;/
.reveal-animation.ng-enter {
-webkit-transition: 1s linear all; /&#42; Safari/Chrome &#42;/
-moz-transition: 1s linear all; /&#42; Firefox &#42;/
-o-transition: 1s linear all; /&#42; Opera &#42;/
transition: 1s linear all; /&#42; IE10+ and Future Browsers &#42;/
/&#42; The animation preparation code &#42;/
opacity: 0;
}
/&#42;
Keep in mind that you want to combine both CSS
classes together to avoid any CSS-specificity
conflicts
&#42;/
.reveal-animation.ng-enter.ng-enter-active {
/&#42; The animation code itself &#42;/
opacity: 1;
}
&lt;/style&gt;
&lt;div class="view-container"&gt;
&lt;div ng-view class="reveal-animation"&gt;&lt;/div&gt;
&lt;/div&gt;
</pre>
<p>The following code below demonstrates how to perform animations using <strong>CSS animations</strong> with Angular:</p>
<pre class="prettyprint linenums">
&lt;style type="text/css"&gt;
.reveal-animation.ng-enter {
-webkit-animation: enter_sequence 1s linear; /&#42; Safari/Chrome &#42;/
-moz-animation: enter_sequence 1s linear; /&#42; Firefox &#42;/
-o-animation: enter_sequence 1s linear; /&#42; Opera &#42;/
animation: enter_sequence 1s linear; /&#42; IE10+ and Future Browsers &#42;/
}
&#64-webkit-keyframes enter_sequence {
from { opacity:0; }
to { opacity:1; }
}
&#64-moz-keyframes enter_sequence {
from { opacity:0; }
to { opacity:1; }
}
&#64-o-keyframes enter_sequence {
from { opacity:0; }
to { opacity:1; }
}
&#64keyframes enter_sequence {
from { opacity:0; }
to { opacity:1; }
}
&lt;/style&gt;
&lt;div class="view-container"&gt;
&lt;div ng-view class="reveal-animation"&gt;&lt;/div&gt;
&lt;/div&gt;
</pre>
<p>Both CSS3 animations and transitions can be used together and the animate service will figure out the correct duration and delay timing.</p>
<p>Upon DOM mutation, the event class is added first (something like <code>ng-enter</code>), then the browser prepares itself to add
the active class (in this case <code>ng-enter-active</code>) which then triggers the animation. The animation module will automatically
detect the CSS code to determine when the animation ends. Once the animation is over then both CSS classes will be
removed from the DOM. If a browser does not support CSS transitions or CSS animations then the animation will start and end
immediately resulting in a DOM element that is at its final state. This final state is when the DOM element
has no CSS transition/animation classes applied to it.</p>
<p><h2>JavaScript-defined Animations</h3>
In the event that you do not want to use CSS3 transitions or CSS3 animations or if you wish to offer animations on browsers that do not
yet support CSS transitions/animations, then you can make use of JavaScript animations defined inside of your AngularJS module.</p>
<pre class="prettyprint linenums">
var ngModule = angular.module('<div class="nocode nocode-content" data-popover data-content="Replace this or ngModule with the module that you used to define your application." data-title="Your AngularJS Module">YourApp</div>', []);
ngModule.animation('.my-crazy-animation', function() {
return {
enter: function(element, done) {
//run the animation
<div class="nocode nocode-content" data-popover data-content="This function (if provided) will perform the cancellation of the animation when another is triggered" data-title="Cancel Animation">return function(element, done) {</div>
//cancel the animation
}
}
leave: function(element, done) { },
move: function(element, done) { },
show: function(element, done) { },
hide: function(element, done) { },
addClass: function(element, className, done) { },
removeClass: function(element, className, done) { },
}
});
</pre>
<p>JavaScript-defined animations are created with a CSS-like class selector and a collection of events which are set to run
a javascript callback function. When an animation is triggered, $animate will look for a matching animation which fits
the element&#39;s CSS class attribute value and then run the matching animation event function (if found).
In other words, if the CSS classes present on the animated element match any of the JavaScript animations then the callback function
be executed. It should be also noted that only simple class selectors are allowed.</p>
<p>Within a JavaScript animation, an object containing various event callback animation functions is expected to be returned.
As explained above, these callbacks are triggered based on the animation event. Therefore if an enter animation is run,
and the JavaScript animation is found, then the enter callback will handle that animation (in addition to the CSS keyframe animation
or transition code that is defined via a stylesheet).</p>
