beforeunload

Hi,

I have the following script which I'm trying to make work:

<head>
<script>
window.onbeforeunload =
if (!document.forms['f4'].elements['Continue'].value==true;){
function() {
return("This will take you back to the login page.");
}
}
</script>
</head>

In short I want to alert a user when they leave the page unless they
click the button Continue.

I'm sure this is quite simple, and will work on it. Will post the
solution if I find it.

Thanks

A

Yes - how can I achieve this?? How can I alert the user when they
leave a page, unless they click the Continue button.

^^^^^^
That's a sign of inadequate programming comprehension.
function() {
return("This will take you back to the login page.");

Will it? Can you be sure that the so-called "login page" would be
reached? What if the user enters "www.humgrummit.com"?
