The YUI Animation Utility makes adding animation effects to HTMLElements easy.
The first thing we need to do is load the Animation source file and dependencies:
For this example, we will animate the width of the
<div> element named
Add a little style so that we can see the animation in action:
demo element and a button to run the animation:
Now we create an instance of
YAHOO.util.Anim, passing it the element we wish to animate, and the style attribute(s) to be animated. Each attribute requires at least a
by field, which will be used as the ending value. A
from field is optional; if omitted the animation starts from its current value.
The final step is to call the
animate method on our instance to start the animation. The button will be the trigger that begins the animation sequence:
This is a basic example of the YUI Animation Utility.
