JS:

$(function () {
 $(&#39;#scroll-table&#39;).scroll(function (e) {
  var pagination = {
   page: 0,
   pageSize: 20
  };
  //滚动条位置 
  var scrollTop = $(&#39;#scroll-table&#39;).scrollTop();

  //可视窗口的高度 
  var viewportHeight = $(&#39;#scroll-table&#39;).height();

  //整个页面可以滚动的高度 
  var scrollHeight = $(&#39;#scroll-table&#39;)[0].scrollHeight;

  //“如果滚动条的位置”+“可视窗口的高度”=“整个页面可以滚动的高度”，那么就调用相应的函数加载数据 
  if (Math.round(scrollTop + viewportHeight) == scrollHeight) {
   var tr = $(&#39;<tr><td> good </td> <td> nice </td> /tr>&#39;);
   $(&#39;#scroll-tbody&#39;).append(tr);

   /*
    * pagination.page += 1;
    * dataAjax(pagination); //这里做第二页的数据请求并添加进表格 
    */
  }
