jQuery ajax大資料量each輸出

<script>
var tbodystr = "";
$.ajax({
                type: "get",
                url: "gettable.ashx",
                cache: false,
                datatype: "json",
                success: function(msg) {
                    $.each(msg, function(i) {
                        tbodystr = "<tr>";
                        tbodystr += "<td>" + msg[i]._0 + "</td>";
                        tbodystr += "<td>" + msg[i]._1 + "</td>";
                        tbodystr += "<td>" + msg[i]._2 + "</td>";
                        tbodystr += "</tr>";
                        $("#tbmain tbody").append(tbodystr);
                    });
                }
            });

</script>

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

大類的資料,就最佳化下看看

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(""));
}
