javascript - Jquery ajax infinite scroll exclude footer height -


i'm working on ajax infinite scroll. have below code make ajax request after scrolling @ end,

$(window).scroll(function(){ if($(window).scrolltop() >= ($(document).height() - $(window).height())){     loadlist(); } });

but fires when scrolled @ end (including footer.). want fired when footer starting show while scrolling (footer height 300px).

i researched , tried following code,

$(window).scroll(function(){ if($(window).scrolltop() >= ($(document).height() - $(window).height()) - 300){ // 300px footer height     loadlist(); } });

but seems dirty. function gets fired many times when scrolling. solutions ?

i'd take approach of triggering behaviour when footer element first scrolls view. 

var $footer = $("#my-footer");  $(window).scroll( function() {     if (isscrolledintoview($footer) ) loadlist(); });

see check if element visible after scrolling code isscrolledintoview().
