Calling function with Onunload

I'm having trouble calling a user defined function when using onUnload, but I have no problem calling a javascript function using onUnload.

<BODY onUnload= alert('Testing')>
This works

<BODY onUnload=&quot;Test()&quot;>
Doesn't Work

function Test()
{
//code
}

Is there something wrong with the syntax?

Thanks,
Dave

This works:

<html>
<body onunload=&quot;Test();&quot;>
<script type=&quot;text/JavaScript&quot;>
<!--
function Test(){
alert(&quot;Testing!&quot;);
}
//-->
</script>
</body>
</html>

I tried adding the semicolon, but it still won't work

Just a question...Stewart, did you actually try putting the alert inside your function to make sure? Rick's script works fine for me. Maybe the problem is the function itself??

Stewart,

Under what browser are you running this? IE allows for all kinds of junk to run on an onUnload event, but Netscape and Mozilla are more strict and when you close one of those browsers, the child procs are usually killed as well. So, if you're trying to, say, pop up an alert window, it pretty much ain't gonna happen.

I might be fulla dookie, but this seems to be the case all over.

Cheers,

It works after all, my fault. I didn't realize that the function declaration was supposed to be included in the html, as I previously had the declaration later in the javascript code. Now I'm having a new problem. It seems like I can't call a setTimeout function inside the function called by onUnload. Any ideas why this is happening?

Thanks,
Dave

Sure -- garbage collection. See my previous note. onUnload events have to be quick things because a well-behaved browser knows that a User closing the browser Wants It Gone. If you set up a timeout event, I'd actually be surprised such a thing would ever happen, as it pretty much goes against the whole principle of Killing the Browser.
