Hi All

could you please tell me why the following script does not fire on my machine . the body of "tellerror" function does not fired at all but the error message suppressed . it suppose to be fired because I created an element on a page on different domain in onload event and if I remove window.onerror then I'll get an access denied error .

<head>
<script language="JavaScript">
function tellerror(){
alert('An error has occurred!') ;
return true ;
}
window.onerror=tellerror

</script>

</head>

<body onload="window.document.frames['frame1'].document.createElement('SPAN');">
<iframe id="frame1" src="http://www.msn.com/" width="100%" height="100%" >
</body>

Works as expected for me with exactly the same code.

Hi alihussein3,

Are you using a product like Norton Internet Security or some other Ad blocking software? These programs add their own error stuff to the page, to prevent errors from missing ad stuff. For example, NIS adds this:

window.onerror = SymError;

If you have that on your page, your custom error handler may have been overwritten.....

Cheers,
Imar
