jquery fading effect
<p>i have this javascript code to which i want to add the jquery fade-in effect</p>

<pre><code>hover.addEventListener('mouseover',function () {Core.addClass(cpanel,"on");},false);
</code></pre>

<p>Core is another library i am using. 
the above event listener just enables the cpanel div to visible state. how do i make it fade into the view. i am using jquery-ui and am very new at it.</p>

<p>thanks a lot in advance.</p>
