我的滚动加载在IE 8上不起作用

Question

IT's all in the title, the loading on scroll is working fine on chrome and FF but not in IE 8

var lastScrollTop = 0;
$(window).scroll(function(){
var st = $(this).scrollTop();
   if (st > lastScrollTop){
    openFromButton()
    } 
  lastScrollTop = st;
});

It seems that the problem comes from scrollTop

Answer 1

Try document instead of window.

var lastScrollTop = 0;
$(document).scroll(function(){
var st = $(this).scrollTop();
   if (st > lastScrollTop){
    openFromButton()
    } 
  lastScrollTop = st;
});
