at this link: http://jqueryui.com/demos/tabs/ when we look "view source", we have:
<div id="tabs">
<ul>
<li><a href="#tabs-1">...</a></li>
<li><a href="#tabs-2">...</a></li>
<li><a href="#tabs-3">...</a></li>
</ul>
<div id="tabs-1">...</div>
<div id="tabs-2">...</div>
<div id="tabs-3">...</div>
</div>
so what I want to know, how to implement this with class instead of id,
considering this portion of code will be used multiple times that may be loaded ajax,
in different times.
