I\'m having an issue in IE9 with onbeforeunload -- when the code below is run it repeatedly brings up a dialog asking if you want to stay or leave the page.

I modified

    You cannot send an AJAX request while the page is unloading as most browsers block it. You should ask the user to stay on the page if there is dirty data. That's all you should do from your onbeforeunload handler

    Try your code without calling $.post and it should behave as expected
