confirm() on [removed]

Question

I want to show a confirmation dialog if the user wants to leave the page with unsaved form data. What I have is:

window.onbeforeunload = function() {
    if

With jQuery, you can set the same handlers. The code may defer based on your version.

    function AnyFunction(e){ /**** your code *****/ };

    $(function () {
      $(window).bind('unload', function (e) { return AnyFunction(e); });
      $(window).bind('beforeunload', function (e) { return AnyFunction(e); });
    });

You can also change the confirm or alert function using plugins as bootbox.
