jQueryEasyUI：如何重新加载combogrid？

Question

我有一个ASP.NET Core应用程序，我想使用ajax调用将数据加载到easyUI combogrid。我这样做：

    var jsonData = [];

    populateGrid();// Here is ajax call, jsonData array is populated

    var g23=$('#ipCC').combogrid({
        panelWidth: 450,
        value: '006',
        idField: 'customerID',
        textField: 'fullName',
        source:jsonData,
        columns: [[
                {field: 'customerID', title: 'customerID', width: 60 },
                {field: 'fullName', title: 'fullName', width: 100 }
            ]]
    });

    var g25 = $('#ipCC').combogrid('grid');//<-----------------error
    g25.datagrid('loadData', jsonData);

但是当我尝试将ptr设置为'grid'时，会收到错误消息：

未捕获的TypeError：无法读取属性'jQuery3110372840994670562'未定义在U.get（jquery.min.js：3）在U.access（jquery.min.js：3）在Function.data（jquery.min.js：3）在网格上（jquery.easyui.min.js：16058）在r.fn.init。$。fn.combogrid（jquery.easyui.min.js：16033）在索引：240

怎么了？如何修复它并将数据加载到combogrid？

<input id="cc" name="dept" value="01">
<script type="text/javascript">
    var jsonData = {"rows":[
                            {"customerID":"ID1","fullName":"John XYZ"},
                            {"customerID":"ID2","fullName":"John ABC"},
                            {"customerID":"ID3","fullName":"John DEF"},
                            {"customerID":"ID4","fullName":"John GHJ"},
                            {"customerID":"ID5","fullName":"John KLM"},
                            {"customerID":"ID6","fullName":"John PQR"},
                            {"customerID":"ID7","fullName":"John STU"},
                            {"customerID":"006","fullName":"John STU 2"} 
                            ]};

    //populateGrid();// Here is ajax call, jsonData array is populated

    var g23 =   $('#cc').combogrid({
                    panelWidth:450,
                    value:'006',         
                    idField:'customerID',
                    textField:'fullName',
                    source: jsonData,
                    columns: [[
                                {field: 'customerID', title: 'customerID', width: 60 },
                                {field: 'fullName', title: 'fullName', width: 100 }
                            ]],
                });

    var g25 = $('#cc').combogrid('grid'); //<-----------------NO error

    g25.datagrid('loadData', jsonData);
</script>

我从EasyUI的示例中获取了hint，并且您的JSON必须具有“行”数组。
