How to determine if a scrollable element has been scrolled to the bottom

$(element).scroll(function () {
    var scrollH = $(this)[0].scrollHeight;
    var clientH = $(this)[0].clientHeight;
    var offset = scrollH - clientH;

    if (offset == $(this).scrollTop()) {
        /**
         * action to perform when scrollable 
         *  area hits bottom
         */  
    }
});

You would think something this simple would be easy to find.

I did test in the latest browsers for Chrome, Firefox, and Safari (sorry IE) on a Mac and it appears stable.

Should also mention that jQuery-1.9.1 was used to generate the example.
