<h3>Using the NodeFX Plugin</h3> |
|
|
144 |
<p>For this example, we will use <code>Node</code>'s <code>fx</code> plugin to animate the element. The plugin adds the anim instance to the <code>Node</code> instance, pre-configuring it to use the Node instance as the <code>Anim</code>'s node. The <code>plug</code> method accepts a class to construct and an optional config to pass to the constructor.</p> |
|
|
145 |
<p>Setting the <code>from</code> attribute to the expanded height of the element allows us to toggle the effect using the <code>reverse</code> attribute, which we will see below (<code>from</code> uses current value when omitted).</p> |

<h3>Creating the Control Element</h3> |
|
|
167 |
<p>Because our behavior only works when JS is available, let's go ahead and add our control element using JS as well.</p> |
|
|
168 |
|
|

<h3>Toggling Animation Behavior</h3> |
|
|
181 |
<p>Before calling <code>run</code> in our <code>click</code> handler, we will use the <code>reverse</code> attribute toggle the direction of the animation depending on whether its opening or closing.</p> |
|
|
182 |
|
|
|
183 |
<textarea name="code" class="JScript" cols="60" rows="1"> |

<h3>Running the Animation</h3> |

<p>Finally we add an event handler to run the animation.</p> |
