JqG​​rid不显示数据MVC

请检查我正在使用的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

 $(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 }); });  

我的控制器方法看起来像我按照jqGrid文档格式化数据。

  [HttpGet] public JsonResult GetData() { List myList = CallProcedure("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，你能指出我在哪里错了吗？ 提前致谢

Json看起来如下

  { "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"] ] } 

网格仍为空白:(

更新操作方法以不同格式返回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的不同之处在于它包含“for”CP“，”Val1“的名称。并且网格仍然是空白的

这有什么不对？ 当页面加载时，断点就会出现在这里，它会像预期的那样对json进行trertur，

  public JsonResult GetData() { List dd = CallProc("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

我在评论中建议的是：

  { "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"] 

]}

我总是得到关于JSON结果的多个网格问题并且它解决了它们。

Answer 2

JqG​​rid不接受行中的任何json，它需要在名称值对中格式化的json，它与列模型中的name字段匹配。

这里是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"}, ..... ] } 

要获得该json，您需要更新您的操作方法，如下所示

  public JsonResult GetData() { List myList = CallProcedure("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); } 

Answer 3

您是否在调试器中检查了服务器的结果？ 控制台中是否有任何问题？

如果没有，可能会尝试删除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() } }) };
