You don't want the refresh, you want the onbeforeunload event.
Sample code from article
<HTML>
<head>
<script>
function closeIt()
{
return "Any string value here forces a dialog box to \n" +
"appear before closing the window.";
}
window.onbeforeunload = closeIt;
</script>
</head>
<body>
<a href="">Click here to navigate to
</body>
</html>
The closest you could get is the window.onbeforeunload event:
window.onbeforeunload = function (e) {
var e = e || window.event;
// For IE and Firefox
if (e) {
e.returnValue = 'Leaving the page';
}
// For Safari
return 'Leaving the page';
};
It is important to note that you need to return a string from this function.
