       alert("END!");
   }
});

Answer 2

I used something like this once :)

   if($(window).scrollTop() + $(window).height() > $(document).height() - 50) {
                       //alert
}

Just play with the numbers, this one is built in to display a warning almost until the end of the scroll

Answer 3

Try this. When you scroll the page, and if the page is reached to the bottom, then a warning message will appear.

$(window).scroll(function() {
   if($(window).scrollTop() + $(window).height() == $(document).height()) {
       alert("Bottom Reached!");
   }
});
