HTML: <td class="ewPointer" onmousedown="ew_Sort(event,'sampple.asp?order=brgy%5Fid&ordertype=ASC',1);">

I just want to disable the onmousedown function and replac开发者_高级运维e it with my jquery function.

I used this code but didn't work.

$('.ewPointer').live('click',function(e) {e.preventDefault(); });

Is there a way?
