window.onUnLoad : Window Object « Window « JavaScript Tutorial





The onUnLoad event handler is fired when the page is unloaded. This occurs when the user leaves the page for another page.

The onUnLoad event handler in a document will fire before an event handler loaded in the tag.

<html>
    <body onUnLoad='alert("Please do not leave!")'>
</html>
