How to detect browser window close action
Posted By : Kamaldeep Singh | 30-Sep-2015
In my previous blog I have explained how to Prevent Internet Explorer from caching http calls so that each time you can get fresh data from the server. Here is its link: Prevent Internet Explorer from caching http calls
Now in this blog, I will let you know how to detect browser window close action. Now this action may be sometimes required where you want to perform some kind of function on window close. Say you may be required to call Logout function on a secured website. Now this functionality can be done by the following line of javascript code
<html>
<head>
<title>Hello</title>
<script type="text/javascript" language="Javascript">
function DetectBrowserExit() {
alert('Here you can execute task you want');
}
window.onbeforeunload = function() {
DetectBrowserExit();
}
</script>
</head>
<body>
Close this browser to notice the browser close event
</body>
</html>
And if we talk about its browser compatibility, I have tested this in following browsers:-
- Google Chrome
- Internet Explorer
- Mozilla Firefox
- Safari
Thats all for now.
