| JAVASCRIPT ONUNLOAD EVENT
The javascript onunload event handler is used to trigger a script when the page unloads ie. when you close or browse away from a page. The onunload event calls the action from the <body> or <frameset> tags:
Example:
<body onunload="alert('Please don\'t go');">
The above example will output Please don't go as you try to close the page or browse away.
The onunload event can also call a function as follows:
<head>
<script type="text/javascript">
function dontGo()
{
alert('Please don\'t go');
}
</script>
</head>
<body onunload="dontGo();">
