Try:

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

@valkharitonashvili What do you mean not working? Message is not alerted at all? – laaposto Aug 20 '14 at 08:51
Does window and document keywords belong to WebAPI or HTML or Jquery? – sofs1 Apr 06 '18 at 12:05

I used something like this once :)

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

Just play with the numbers, this one is built to pop out the alert just almost before the end of the scroll

as explained, this one shows alert 50px before the end of the page. I pasted it here because I find it very useful in a lot of things, and it uses the consept of the main question here. I used it when developing a blog with a "load more posts" button automatically when it scrolls almost to the bottom of the page. – Imnotapotato Aug 20 '14 at 08:11

Try this one, When you scroll the page and if the page is reached to bottom, then alert message will get displayed.

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