JqG​​rid不显示数据MVC

Question

请检查我的 jqgrid，它只显示空白网格，我的 json 是根据网格的预期格式。我正在使用 jqGrid 4.4.4

<script type="text/javascript">
        $(function () {
            $("#myGrid").jqGrid({
                url: '/Home/GetData/',
                datatype: "json",
                contentType: "application/json; charset-utf-8",
                mtype: 'GET',
                colNames: ['CP', 'Val1', 'Val2', 'Val3'],
                colModel: [
                                { name: 'CP', index: 'CP', width: 150 },
                                { name: 'Val1', index: 'Val1', width: 150 },
                                { name: 'Val2', index: 'Val2', width: 150 },
                                { name: 'Val3', index: 'Val3', width: 150 }
                ],
                rowNum: 5,
                rowList: [5, 10, 15],
                pager: '#pager',
                sortname: 'CP',
                viewrecords: true,

                sortorder: "asc",

                viewrecords: true,

                caption: "JSON Example"
            });
            $("#myGrid").jqGrid('navGrid', '#pager', { edit: true, add: true, del: true });

        });

    </script>

我的控制器方法看起来像，我正在按照 jqGrid 文档格式化数据。

 [HttpGet]
        public JsonResult GetData()
        {
            List<Rate> myList = CallProcedure<Rate>("getVal").ToList();


            var jsonData = new
            {
                total = myList .Count,
                page = 1,
                records = 10,
                rows = (
                  from d in myList 
                  select new
                  {
                      id = d.CP,
                      cell = new string[] {
                      d.CP.ToString(),
                      d.Val1.ToString(),
                      d.Val2.ToString(),
                      d.Val3.ToString()
                      }
                  }).ToArray()
            };



            return Json(jsonData, JsonRequestBehavior.AllowGet);
        }

尝试在网格中设置 jsonReader 但仍然没有成功，你能指出我哪里出错了吗？提前致谢

Json 如下所示

   {
    "total": 1,
    "page": 1,
    "records": 25,
    "rows": [{
        "id": "AUSD",
        "cell": ["AUSD    ", "0.000000", "0.72315000", "0.000000"]
    }, {
        "id": "PPFF",
        "cell": ["PPFF    ", "0.000000", "1.10288000", "0.000000"]
    }, {
        "id": "XTYU",
        "cell": ["XTYU    ", "0.000000", "1.41479000", "0.000000"]
    }, {
        "id": "NUSD",
        "cell": ["NUSD    ", "-0.000020", "0.67097000", "-0.000020"]
    }, {
        "id": "USED",
        "cell": ["USED    ", "0.000000", "3.67278000", "0.000000"]
    }, {
        "id": "UAD",
        "cell": ["UAD    ", "0.000120", "1.37037000", "0.000020"]
    }]
}

新的 json 看起来像，

{
    "total": 1,
    "page": 1,
    "records": 25,
    "rows": [
        ["Val1    ", "0.000000", "0.72315000", "0.000000"],
        ["Val12    ", "0.000000", "1.10288000", "0.000000"],
        ["Val13    ", "0.000000", "1.41479000", "0.000000"],
        ["Val14    ", "-0.000020", "0.67097000", "-0.000020"],
        ["Val15    ", "0.000000", "3.67278000", "0.000000"],
        ["Val16    ", "0.000120", "1.37037000", "0.000020"],
        ["Val17    ", "0.000000", "0.99843000", "0.000000"],
        ["Val18    ", "0.000000", "24.53100000", "0.000000"],
        ["Val19    ", "0.000000", "6.76500000", "0.000000"],
        ["Val23    ", "0.000000", "7.77250000", "0.000000"]

    ]
}

网格仍然是空白的:(

更新动作方法以返回不同格式的json，

{
    "total": 25,
    "page": 1,
    "records": 10,
    "rows": [{
        "CP": "ADRR",
        "Val1": "0.000000",
        "Val2": "0.72315000",
        "Val3": "0.000000"
    }, {
        "CP": "TRRT",
        "Val1": "0.000000",
        "Val2": "1.10288000",
        "Val3": "0.000000"
    }, {
        "CP": "TRER",
        "Val1": "0.000000",
        "Val2": "1.41479000",
        "Val3": "0.000000"
    }]
}

json 中的不同之处在于它包含 " 代表 "CP"、"Val1" 名称。并且网格仍然是空白的

这里有什么问题？页面加载时断点就到了，它按预期返回json，

    public JsonResult GetData()
            {
                List<Live> dd = CallProc<Live>("getLiveData").ToList();


                var jsonData = new
                {
                    total = 1,
                    page = 1,
                    records = dd.Count,
                    rows = (
                      from d in dd
                      select new string[]
                      {
                          CP = d.CP.ToString(),
CP1 = d.CP1.ToString(),
                           CP2 = d.CP2.ToString(),
Cp3 =                           d.Cp3.ToString()
                      }).ToArray()

                };


                string json = new JavaScriptSerializer().Serialize(jsonData); //just to check what json I am getting

                return Json(jsonData, JsonRequestBehavior.AllowGet);
            }

Answer 1

我在评论中的建议是：

  {
"total": 1,
"page": 1,
"records": 25,
"rows": [["AUSD    ", "0.000000", "0.72315000", "0.000000"], 
         ["2", "PPFF    ", "0.000000", "1.10288000", "0.000000"],
         ["XTYU    ", "0.000000", "1.41479000", "0.000000"]

] }

我已经遇到了关于 JSON 结果的多个网格的问题，它解决了这些问题。

Answer 2

JqGrid 不接受行中的任何 json，它需要格式为名称值对的 json，它与列模型中的名称字段匹配。

Here JsFiddle Sample

{
    "total": 1,
    "page": 1,
    "records": 25,
    "rows": [
        {CP: "Val1    ", Val1: "0.000000", Val2:"0.72315000", Val3: "0.000000"},
        {CP: "Val12    ",Val1: "0.000000", Val2: "1.10288000",Val3: "0.000000"},
        .....

    ]
}

要获取该 json，您需要按如下方式更新您的操作方法

 public JsonResult GetData()
        {
            List<Rate> myList = CallProcedure<Rate>("getVal").ToList();


            var jsonData = new
            {
                total = myList .Count,
                page = 1,
                records = 10,
                rows = (
                  from d in myList 
                  select new
                  {
                     id = d.CP,
                     CP = d.CP.ToString(),
                     Val1= d.Val1.ToString(),
                     Val2 = d.Val2.ToString(),
                     Val3=  d.Val3.ToString()
                  }).ToArray()
            };



            return Json(jsonData, JsonRequestBehavior.AllowGet);
        }

您是否在调试器中检查了服务器的结果？ 控制台中是否显示任何问题？

如果没有，可以尝试删除 jsonData 块中的“ToArray()”。

            var jsonData = new
        {
            total = myList .Count,
            page = 1,
            records = 10,
            rows = (
              from d in myList 
              select new
              {
                  id = d.CP,
                  cell = new string[] {
                  d.CP.ToString(),
                  d.Val1.ToString(),
                  d.Val2.ToString(),
                  d.Val3.ToString()
                  }
              })
        };
