jquery 奇怪问题，咋就不兼容js呢

$.post("../ajax/userAutoUnitBuyListAction.jspx",{},function(data){
          var rel=data.userAutoUnitBuyList;
          if(rel!=null){

           //document.getElementById(“autoBuyUserList”).innerHTML=""; //这样写是报错的，调试了一下进入jquery文件里面，恼火
          $("#autoBuyUserList").empty();//修改成这样就顺利了，⊙﹏⊙b汗
          var rows='<tr bgcolor="#F4FAFF" class="blue">'
