Question

Can I pop up a confirmation dialog when the user is closing the window in Safari/Chrome?

Answer 1

+4 A:

This works perfectly for me in both Chrome and Safari:

<html><body><p>Test</p>
<script>window.onbeforeunload = function() { return "Sure?"; }</script>
</body></html>

When I try to close the window, I get the prompt.

Hmmmmmmm. That's weird...My code wasn't working in Safari.Maybe it's because I was using Prototype's Event.observe() to attach the handler...Anyways, thanks a lot! You just made my life so much easier!

Answer 2

+1 A:

StackOverflow itself uses onbeforeunload, and it works fine for me in Safari:

function setConfirmUnload(a){window.onbeforeunload=a?function(){return a}:null}
