                onLoadSuccess: function (data) {//
                    alert("data success");
                    //

                }
            });
        }

my json data

{
  "total": 1,
  "rows": [
    {
      "XH": 1,
      "DYH": "hello"
    }
  ]
}

this is the result, and the data is not loaded.
