I have a javascript error that I want to hide from the users. I found this code online but is does not seem to work.

<script>
function stopErrors() {
return true;
}
window.onerror = stopErrors;
</script>


any ideas?

Thanks in advance,
Michael

ps. its been a long time since I have been here... the new look is awesome :)

Never mind... it seems to be working now... too many interuptions make it hard to get anything done.
Thanks

actually, i'm pretty sure that should be:

<script>
function stopErrors() {
return false;
}
window.onerror = stopErrors;
</script>

no, its true like I have in the 1st post. I just tested it.

<HTML>
<HEAD>
<TITLE> New Document </TITLE>
<script>
function stopErrors() {
return true ;
}
window.onerror = stopErrors;
</script>
</HEAD>

<BODY>
<script>
alert(blah);
</script>
</BODY>
</HTML>


if you change it to false it will tell you that blah is undefined (because it is looking for a vaiable called blah).

in what browser? i have a function like that on my website, to quietly catch all javascript errors and log them. i've tested the script in Mozilla and IE 5, 5.5, and 6, and it works fine in all of them, and it uses return false.

yeah i did. it's weird. my function works in mozilla and in IE, but these couple of lines of code, both browsers throw errors if i set it to return false. i don't know. for the moment, i'm going to agree that you're right, and it's return true, but i don't know why. according to the Guide, it ought to be return false, and i am truely confused. i'm not gonna be around for the next two days, but when i get back, i will definitely be looking into this.

To suppress JavaScript error dialogs when calling a function using onError, the function must return true. - www.devguru.com (http://www.devguru.com/Technologies/ecmascript/quickref/evhan_onerror.html)
