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 allpage = @Model.PageCount; //总页码，会从后台获取

          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);

      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
