Is it bad practice to assign a css class for the sole purpose of finding it with jQuery?
<p>I'm using ASP.NET, not the newest one with that clientIdMode stuff.  So, the control ids are generated and funky.</p>

<p>There are lots of ways of passing ids around, but lately I've been assigning a 'fake' css class to the control I'm interested in.  Then in a js file I use jQuery to find the control.</p>

<p>Is this bad practice?  It seems a lot like the ajaxControlToolkit's behaviorId to me...  Is the behaviorId bad practice as well?</p>
