How to trigger a browser window or tab close event with jQuery

Question

Is there any way to trigger a window/tab close event with jQuery. I already tried with ``` $('selector').unload() ``` But it didn't work.

Accepted Answer

You can use `unload()` on the `window` property in jQuery:

```
$(window).unload(function() {
   //do stuff
});
```

You don't need jQuery to do it though, you can use good ol' fashioned JavaScript:

```
window.onbeforeunload = function(e){
    var msg = 'Are you sure?';
    e = e || window.event;

if(e)
        e.returnValue = msg;

return msg;
}
```
