Can 'onbeforeunload' (ie) be used to trigger a javascript?
I can't find any info on how or if this is possible.
Regards.

Yes, sure, the following inserts a warning message into the page with
both IE 6 and Mozilla 1.7 for me if I try to navigate away from the page
so script is executed:
<html>
<head>
<title>calling script in the beforeunload event handler</title>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<script type="text/javascript">
function showWarning (message) {
var p;
if (document.createElement && (p = document.createElement('p'))) {
p.className = 'warning';
p.appendChild(document.createTextNode(message));
document.body.insertBefore(p, document.body.firstChild);
}
}
window.onbeforeunload = function (evt) {
showWarning('Are you sure you want to leave this page?');
if (!evt) {
evt = window.event;
}
if (evt) {
evt.returnValue = 'Are you sure you want to leave this page?';
return evt.returnValue;
}
}
</script>
<style type="text/css">
p.warning {
color: red;
background-color: white;
font-weight: bold;
font-size: 110%;
}
</style>
</head>
<body>
