<h2>Setting up the HTML</h2> |
|
|
70 |
<p>First we add some HTML to animate.</p> |
|
|
71 |
|
|
|
72 |
<pre class="code prettyprint"><div id="demo" class="yui3-module"> |

<h3>The End Event</h3> |
|
|
75 |
<a title="fade then remove element" class="yui3-remove"><em>x</em></a> |
|
|
76 |
</div> |
|

<div class="yui3-bd"> |

<p>Click the X in the header to fade out the element and remove it from |

|
|
83 |
|
|
|
84 |
|
|
|
85 |
<h2>Creating the Anim Instance</h2> |
|
|
86 |
<p>Now we create an instance of <code>Y.Anim</code>, passing it a configuration object that includes the <code>node</code> we wish to animate and the <code>to</code> attribute containing the properties to be transitioned and final values.</p> |
|
|
87 |
|
|
|
88 |
<pre class="code prettyprint">var anim = new Y.Anim({ |
|
|
89 |
node: '#demo', |
|
|
90 |
to: { opacity: 0 } |
|
|
91 |
});</pre> |
|
|
92 |
|
|
|
93 |
|
|
|
94 |
<h2>Handling the End Event</h2> |
|
|
95 |
<p>We will need a function to run when the <code>end</code> event fires. Note that the context of our handler defaults to <code>anim</code>, so <code>this</code> refers to our Anim instance inside the handler.</p> |
|
|
96 |
|
|
|
97 |
<pre class="code prettyprint">var onEnd = function() { |
|
|
98 |
var node = this.get('node'); // this === anim |
|
|
99 |
node.get('parentNode').removeChild(node); // node is an instance of Node |
|
|
100 |
};</pre> |
|
|
101 |
|
|
|
102 |
|
|
|
103 |
<h2>Listening for the End Event</h2> |
|
|
104 |
<p>Now we will use the <code>on</code> method to subscribe to the <code>end</code> event, passing it our handler.</p> |
|
|
105 |
|
|
|
106 |
<pre class="code prettyprint">anim.on('end', onEnd);</pre> |
|
|
107 |
|
|
|
108 |
|
|
|
109 |
<h2>Running the Animation</h2> |
|
|
110 |
<p>Finally we add an event handler to run the animation.</p> |
|
|
111 |
<pre class="code prettyprint">Y.one('#demo .yui3-remove').on('click', anim.run, anim);</pre> |
|
|
112 |
|
