Window Close Event of Browser
Posted by Viral Sarvaiya on April 12, 2011
hi,
recently i get a problem that what if some user accessing my website and close directly browser without logout from the system?
i get good solution with this but this is not 100% secure.
for that we have 2 events in javascript “onbeforeunload” or “onunload”
but onunload event is not working in firefox and some time in IE8 also, so onbeforeunload is suitable for both.
<html>
<head>
<title>Window Close Event of Browser</title>
<script language="javascript" type="text/javascript">
function CloseBrowser() {
alert("Browser is closing");
}
</script>
</head>
<body onbeforeunload="CloseBrowser();">
</body>
</html>
window.onbeforeunload = function() {
return "Are you sure you want to leave this page bla bla bla?"; // you can make this dynamic, ofcourse...
};
As we have already discussed that there is no 100% fool proof way to detect the browser close event in a lot of cases, the above technique can fail. For example if the user kills the browser’s process from task manager, there could be many more cases. Yet in a lot of cases, this technique can be handy.
Best of luck and happy programming.
Thank you.
