I came across this post while Googling for a solution for doing the same thing in MVC. This solution, adapted from Herb's above, seems to work well. Since there's nothing MVC-specific about this, it should work just as well for PHP, Classic ASP, or any other kind of application that uses HTML and JQuery.

var isDirty = false;

$(document).ready(function () {
    $(':input').bind("change select keydown", setDirty);
    $('form').submit(clearDirty);

    window.onbeforeunload = function (e) {
        var msg = "You have unsaved changes. "
        if (isDirty == true) {
            var e = e || window.event;
            if (e) { e.returnValue = msg; }
            return msg;
        }
    };
});

setDirty = function () { isDirty = true; }
clearDirty = function () { isDirty = false; }
