This works but it will override any existing handlers. Consider using: window.addEventListener('beforeunload', function(event) { /* your code */ }); – Yusufali2205 Feb 05 '18 at 19:13

This is most likely a duplicated question. Please have a look at onbeforeunload Javascript event.

You can use jquery unload for that: http://api.jquery.com/unload/

From the `javascript` tag description: *"Unless a tag for a framework/library is also included, a pure JavaScript answer is expected."* – Felix Kling Dec 21 '13 at 03:52
Thank you Felix, I'll take that into account in the future! – Jeff Renaud Dec 21 '13 at 14:21

This will add a new handler:

window.addEventListener('beforeunload', function(event) { 
/* your code */ 
});

If you use:

window.onbeforeunload = function(e){
//Do some thing here
};

This will override any existing handlers and replace it with your own.
