    });    // 全部删除
    $("#btn_removeAll").click(function () {
        $("#userTbody").empty();
    });    //删除一行数据
    /*click只对本身页面有的元素有作用，对于后面新加的元素，不起作用
          $(".myClz").click(function() {
              console.log(123);
          });
     */
    /*选择id=userTbody元素下所有样式名含有myClz的标签,并添加click事件
     *当点击后,向上一级找到tr元素，然后删除
    */
    $(&#39;#userTbody&#39;).on(&#39;click&#39;, ".myClz", function () {
