 onUnload event handler
onunload executes JavaScript
immediately after someone leaves the page. A common use (though not
that great) is to thank someone as that person leaves your page for coming
and visiting.
<body onunload="alert('Thank you. Please come back to this site and visit us soon, ok?')">
There are other event handlers, many belonging to forms.
