IE not working

sapl — Tue, 30 Apr 2013 18:33:45 GMT

The below code work well on Crome but not in IE

<script language=JavaScript>
var sTestEventType='mousedown';
function handleMouseEvent(e) {
var evt = (e==null ? event:e);
if (evt.type!=sTestEventType) return true;
if (evt.which==1)  return true; 
return false;
}
document.onmousedown=handleMouseEvent;
document.onmouseup=handleMouseEvent;
document.onclick=handleMouseEvent;
</script>

Can anyone help to modified it to work in IE.

Thanks
