How to determine if an element has a scrollbar?

Cheers,

I have a div that has the `overflow: auto;` style and that
gets its 
content periodically updated by AJAX. In order to adjust
some styles I 
need to know if the div has the scrollbar present.

Does anybody know how to determine this?


Thanks,
Jonathan

Try:

var has_scroll = (element.scrollHeight !=
element.clientHeight);
