Question

我有一个网页，用于填充jqGrid中的JSON对象（版本4.6.0）。 JSON对象是从java控制器返回的。我如何初始化网格以及如何填充JSON对象如下所示。

问题在于，无论何时单击列标题，我都会丢失以下列中的数据：组织，部门和标题。通过“丢失数据”，我的意思是这些列中的数据由于某种原因消失了。这些列恰好是嵌套的JSON对象。我在这里错过了什么？感谢。

这是从服务器返回的JSON字符串。

[
    {"id":51,"displayName":"John Doe",
     "currentExperience": {"id":26,"orgName":"compnay A","deptName":"MIS","title":"senior software engineer"}},
    {"id":52,"displayName":"Jane Doe",
     "currentExperience": {"id":29,"orgName":"compnay B","deptName":"MIS","title":"software engineer"}}
]

        function initializeGrid($grid, $pager, caption)
        {
            $grid.jqGrid({
                datatype: "local",
                colNames: ["VipId", "ExpId", "Name", "organization", "department", "title"],
                colModel: [

                    { name: "currentExperience.id", hidden: true },
                    { name: "displayName", width: 100, sortable:true },
                    { name: "currentExperience.orgName", width: 100, sortable:true },

谢谢，奥列格。使用以下方法时，问题就消失了。

    function initializeGrid($grid, $pager, caption, json)
    {
        $grid.jqGrid({
            datastr: json,
            datatype: "jsonstring",
            colNames: ["VipId", "ExpId", "Name", "organization", "department", "title"],
            colModel: [
                { name: "id", hidden: true },
                { name: "currentExperience.id", hidden: true },
                { name: "displayName", width: 100, sortable:true },
                { name: "currentExperience.orgName", width: 100, sortable:true },
                { name: "currentExperience.deptName", width: 100, sortable:true },
                { name: "currentExperience.title", width: 100, sortable:true }
            ],
            pager: $pager,
            rowNum: 10,
            rowList: [10, 20, 30],
            sortname: "id",
            sortorder: "asc",
            viewrecords: true,
            gridview: true,
            autoencode: true,
            caption: caption,
            multiselect: true,
            width: 450,
            hidegrid: false
        });
    }

    function wireClickEventForSearchVipsButton($form)
    {
        $(document).on("click", "#btnSearchVips", function(event){
            event.preventDefault();

            var dataMap = composeSearchVipParameters($form);

            <c:url var="link" value="/protected/vips/lookup" />
            $.ajax({
                url: '${link}',
                type: 'GET',
                dataType: 'json',
                accepts: {
                    text: "application/json"
                },
                data: dataMap,
                error: function() {
                    alert('an error occurred');
                },
                success: function(response) {
                    // this is how I populate response from the server
                    if (response) {
                        $grid = $('#gridAvailableVips');
                        if ($grid) {
                            $grid.jqGrid('GridUnload');
                            initializeGrid($('#gridAvailableVips'), $pagerAvailableVips, 'Available Vips', response);
                        }
                    }
                    else {

                    }
                }
            }); // end of $.ajax() 
        }); // end of $(document).on()
    }
