Call Javascript when browser close button is clicked

[sreedhardasi]

Hi,

I would like to call a javascript function when user clicks on
browser's close button. Here is the scenario.

1. User clicks browser close button.
2. User will be displayed a popup or a div with two buttons (Yes or
No) by calling a Javascript function
3. "No" will close the window.
4. "Yes" will cancel the user action and redirect him/her to different
page.

Is it possible to do this? I would appreciate if anyone help me with
this.

Thanks,
Sreedhar

Yes, you can do it using onbeforeunload event listener.

function confirmUnload() {
var mes = "Your message here";
if (event) {
event.returnValue = mes;
}
else {
// do what?
}
}

window.onbeforeunload = confirmUnload;

The first branch is for the standard event handling. I know that
Firefox supports this as well by now but in some rather tweaky way and
I don't have the workaround snippet handy right now, so for // do
what? someone else may help here.

Yes, you can do it using onbeforeunload event listener.

But you should not, as it is an event handler, and the event applies to
navigating away as well. Besides, if there is no sufficient DOM support
you will have a problem.
