gettable.ashx文件

httpcontext.current.response.write(json.getjsondata(ds, keyfileds.tostring()));

大类的数据,就优化下看看

success: function(msg) {

   var tbodystr = [];

   $.each(msg, function(i) {

      tbodystr.push("<tr>");

      tbodystr.push("<td>" + msg[i]._0 + "</td>");

      tbodystr.push("<td>" + msg[i]._1 + "</td>");

      tbodystr.push("<td>" + msg[i]._2 + "</td>");

      tbodystr.push("</tr>");      

   });

   $("#tbmain tbody").append(tbodystr.join(""));//join 将数组已某种形式连接起来

}
