Alert when browser window closed accidentally

When a user clicks the browser’s exit button(in a sense X) I want to open a new window.

For example, The WordPress Admin Panel:
If you are in a WordPress panel and you want to exit, wordpress opens a new window and asks a question.

I would like to do the same.

How can i achieve this?

EDIT:

But don’t exit after click.

You should try using [unload()][1] from jquery:

$(window).unload(function(){
   //Do your call
   alert('before unload');
  });

EDIT – to show yes/no you should use confirm()
