<!-- POP UP BOX BODY CONTENT -->
<div id="dropin" style="position:absolute; visibility:hidden; left:80px; top:693px; width:504px; height:249px;">

<table width="500" height="245" border="0" cellpadding="2" background="whatever.gif" class="popuptable">

<!-- END POP UP BOX BODY CONTENT -->

Is there a way to make this script pop out if a person leaves my page instead when they come to my page?

If this script can't be modified for this purpose, is there any other one here i can use that can pop out like this one but only when a person leaves the page?

window.onload=initbox

Change highlighed above to: window.onbeforeunload

[jinso]

The actually didn't do anything. It just stopped the popup. And on firefox it kind of shows half way on the top and goes away. Would you have a script i could use, that pops up on exit for fire fox and ie and safari.

[rangana]

I'm sorry, but I'm on my wits end. The only thing I could think of is to prompt for a user interaction, possibly as Yes or No:

window.onbeforeunload=function(){return 'Do you really want to leave this page?';}

I think using an alert message to physically halt the unloading of the current page as Rangana has proposed is about the only way to display the Drop In Content box when the user is just about to leave the page.
