移动端web滚动分页的实现方法

<script type="text/javascript">
    var page = 2; //当前页的页码
    var flagNoData = false; //false
    var allpage = @Model.PageCount; //总页码，会从后台获取
    function showAjax(currentIndex) {
      $.ajax({
        url: "@Url.Action("GetEmployeeData", "Home")",
        type: "GET",
        data: {"pageNum":currentIndex},
        success: function (data) {
          //要执行的内容
          showContent(data);
          if (currentIndex >= allpage) { //当前页码大于等于总页码
            flagNoData = true;
          };
          page += 1;  //页数加1
        }
      })
    }
    function scrollFn() {
      //真实内容的高度
      var pageHeight = Math.max(document.body.scrollHeight, document.body.offsetHeight);
      //视窗的高度
      var viewportHeight = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight || 0;
      //隐藏的高度
      var scrollHeight = window.pageYOffset || document.documentElement.scrollTop || document.body.scrollTop || 0;
      if (flagNoData) { //数据全部加载完了
        return;
      } else if (pageHeight - viewportHeight - scrollHeight < 10) {  //如果满足触发条件，执行
        showAjax(page);
      }
    }
    $(window).bind("scroll", scrollFn);  //绑定滚动事件

    function showContent(datacontent)
    {
      $("#contentDiv").append(datacontent);
    }
  </script>
