jQuery滚动位置在实际的Ipad中不起作用

Question

So i am trying to load a content through ajax when reaching a particular position. Below function works pretty good in web page, ipad emulator but doesn't work as expected in real ipad. In real ipad, it doesn't load at the exact position but little later.

  var monitorScrollPosition = function () {
    var reach_point_top = $("#ldp-mainmap-container").offset().top;
    $(window).scroll(function () {
      var scroll_position_top = $(window).scrollTop();
      var scroll_position_bottom = scroll_position_top + $(window).height();
      if ((scroll_position_bottom > reach_point_top) && count < 1) {
        loadContent();
      }
    });
  };

On iPad or any other iOS devices, onscroll event is fired only after you've stopped scrolling.
