jqwidgets 无法从 JSON 加载数据

Question

我正在尝试从 JSON 响应加载 jqwidgets 网格。网格加载空数据，没有任何错误。下面是 Json 响应和 jquery 代码。请告诉我我在这里错过了什么吗？

JSON 数据：

 {"holidayrule":["{\"hid\":\"263\",\"hdates\":\"06/21/2015, 06/22/2015, 06/23/2015, 06/24/2015, 06/25/2015, 06/26/2015, 06/27/2015, 06/28/2015, 06/29/2015, 06/30/2015, 07/01/2015, 07/02/2015\",\"hremark\":\"MyRuleRemark\",\"created_date\":\"2015-02-10 09:59:57.44\",\"updated_date\":\"2015-02-10 09:59:57.44\",\"hname\":\"MyRuleName\"}","{\"hid\":\"264\",\"hdates\":\"05/08/2015, 05/09/2015, 05/10/2015, 05/11/2015, 05/12/2015, 05/13/2015, 05/14/2015, 05/15/2015, 05/16/2015, 05/17/2015, 05/18/2015, 05/19/2015\",\"hremark\":\"ggfgf\",\"created_date\":\"2015-02-10 11:08:52.489\",\"updated_date\":\"2015-02-10 11:08:52.489\",\"hname\":\"gfd\"}","{\"hid\":\"265\",\"hdates\":\"01/23/2015, 01/24/2015, 01/25/2015, 01/26/2015, 01/27/2015, 01/28/2015, 01/29/2015, 01/30/2015, 01/31/2015, 02/01/2015, 02/02/2015, 02/03/2015\",\"hremark\":\"ghhghhghhg\",\"created_date\":\"2015-02-10 15:22:11.69\",\"updated_date\":\"2015-02-10 15:22:11.69\",\"hname\":\"fggg\"}","{\"hid\":\"266\",\"hdates\":\"02/25/2015, 02/26/2015, 02/27/2015, 02/28/2015, 03/01/2015, 03/02/2015, 03/03/2015, 03/04/2015, 03/05/2015, 03/06/2015, 03/07/2015, 03/08/2015\",\"hremark\":\"df\",\"created_date\":\"2015-02-10 15:22:26.133\",\"updated_date\":\"2015-02-10 15:22:26.133\",\"hname\":\"gfggf\"}","{\"hid\":\"267\",\"hdates\":\"01/07/2015, 01/08/2015, 01/09/2015, 01/10/2015, 01/11/2015, 01/12/2015, 01/13/2015, 01/14/2015, 01/15/2015, 01/16/2015, 01/17/2015, 01/18/2015\",\"hremark\":\"hghhghgh\",\"created_date\":\"2015-02-10 15:41:22.527\",\"updated_date\":\"2015-02-10 15:41:22.527\",\"hname\":\"33232\"}","{\"hid\":\"268\",\"hdates\":\"01/15/2015, 01/16/2015, 01/17/2015, 01/18/2015, 01/19/2015, 01/20/2015, 01/21/2015, 01/22/2015, 01/23/2015, 01/24/2015, 01/25/2015, 01/26/2015\",\"hremark\":\"dfdfdfdfd\",\"created_date\":\"2015-02-10 16:23:37.855\",\"updated_date\":\"2015-02-10 16:23:37.855\",\"hname\":\"sdffddf\"}"]}

JQUERY :

var parsedData = JSON.stringify(data.holidayrule);
var source =
        {
            localdata: parsedData,
            datatype: "json"
        }
var dataAdapter = new $.jqx.dataAdapter(source);
// initialize divHolidayruleData
$("#divHolidayruleData").jqxGrid(
{
    width: 850,
    source: dataAdapter,
    pageable: true,
    autoheight: true,
    sortable: true,
    altrows: true,
    columns: [
      { text: 'HID', datafield: 'hid', align: 'center', cellsalign: 'center', width: 70 },
      { text: 'Rule Name', datafield: 'hname', cellsalign: 'center', align: 'center', width: 200 },
      { text: 'Holiday Dates', datafield: 'hdates', align: 'center', cellsalign: 'center', width: 200 },
      { text: 'Remark', datafield: 'hremark', align: 'center', cellsalign: 'center', width: 150 },
      { text: 'Created Date', datafield: 'created_date', align: 'center', cellsalign: 'center', width: 100 },
      { text: 'Updated Date', datafield: 'updated_date', align: 'center', cellsalign: 'center', width: 130 }
    ]
});

我是不是遗漏了什么？

Answer 1

您错过了通过 Data Apdater 进行数据绑定中最基本的概念之一 - 数据字段数组在您的代码中未定义。每个数据字段应该有 "name" 和 "type"。您的数据也在 "holidayrule" 内，这意味着您还必须设置源对象的 "root" 属性。

已更新：

  var data = "[" +

"{\"hid\":263,\"hdates\":\"06/21/2015, 06/22/2015, 06/23/2015, 06/24/2015, 06 /25/2015, 06/26/2015, 06/27/2015, 06/28/2015, 06/29/2015, 06/30/2015, 07/01/2015, 07/02/2015\",\ "hremark\":\"MyRuleRemark\":\"created_date\":\"2015-02-10 09:59:57.44\",\"updated_date\":\"2015-02- 10 09:59:57.44\",\"hname\":\"MyRuleName\"}" + "]"; 变种来源= { 本地数据：数据，数据字段：[{ 名称：'hname'，类型：'string' }]，数据类型："json" };

    var dataAdapter = new $.jqx.dataAdapter(source);

    $("#jqxgridTest").jqxGrid({
        width: 670,
        source: dataAdapter,
        altrows: true,
        selectionmode: 'multiplecellsextended',
        columns: [{
            text: 'HID',
            datafield: 'hid',
            width: 70
        }, {
            text: 'Rule Name',
            datafield: 'hname',
            width: 70
        }, {
            text: 'Holiday Dates',
            datafield: 'hdates',
            width: 70
        }, {
            text: 'Remark',
            datafield: 'hremark',
            width: 70
        }, {
            text: 'Created Date',
            datafield: 'created_date',
            width: 70
        }, {
            text: 'Updated Date',
            datafield: 'updated_date',
            width: 70
        }]
    });
});
