How to cancel browser close window?

Is it possible to cancel the browser close window event? Or at least add a message prompting the user whether they are sure they want to leave the page? I tried doing this with the beforeunload event, but it still closes the browser. I am looking for something similar to Microsoft's exchange website.

Thanks!

window.onbeforeunload

Will work on Safari, IE, Firefox, Chrome, but not Opera.

a ha!

It appears there's a supported JQuery solution

   $(window).unload(function() 
{
  //...
});

this should be cross browser supported...hopefully....
