jquery - Bottom Scroll Checked acts in reverse -


so i'm trying detect if page has scrolled way bottom, , found code:

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

and works... in complete reverse! instead of letting me know when i've scrolled way bottom, detects when i've scrolled @ top.

would tell me why it's doing on end?

this function adding how far down you've scrolled $(window).scrolltop() height of viewport $(window).height(). when greater or equal height of webpage $(document).height(), triggers alert.

my guess webpage isn't higher viewport, alert message triggers @ top of page. see jsfiddle. function working fine (view console log) because content of page taller viewport.
