jquery detect change in class assignment
<p>Does anyone know a way to detect when a given element's class has changed using JQuery?</p>

<p>I'm using the "simply countable" JQuery plug-in to notify the user of the number of characters entered into a text area.  When the user exceeds the allowed number of characters, I would like to disable the "post" button.</p>

<p>Since simply countable changes the assigned CSS class when the limit is reached, my idea was to capture that event so that I could disable the post button, but perhaps there is a better way?</p>

<p>Any suggestions are welcome.</p>

<p>Thanks.</p>
