use jquery to refresh div tab onclick?

Yes it is possible, but you dont need onClick event for this I think

use this

<div id="example">
     <ul>
         <li><a href="ajaxpage1.php"><span>Content 1</span></a></li>
         <li><a href="ajaxpage2.php"><span>Content 2</span></a></li>
         <li><a href="ajaxpage3.php"><span>Content 3</span></a></li>
     </ul>
</div>

Notice that: instead of giving the id of the tab’s division, a page link given
so every time you click on the tabs, it updates it

this degrades gracefully – the links, e.g. the content, will still be accessible with JavaScript disabled.

ps: I am assuming that you having a
working tabs
