在创建新行时将父行 ID 作为 jqGrid 添加到 SubGrid

Question

将 jqGrid 用作子网格，编辑子网格行就可以了。
但是当尝试添加 SubGrid 行时，idDiscount (FK) 应该与 SubGrid 表单一起发布。
我试过在网上搜索这个，但没有找到关于这个主题的任何内容。

如您所见，在我的主网格中，主键是idDiscount， 在子网格上，主键是 cdDiscount 和 FK idDiscount

使用的代码（修剪）

jQuery(gridSelector).jqGrid({
url: '',
        postData: {
        action: "MainGrid"
        },

        datatype: 'json',
        colNames: ['idDiscount'],
        colModel: [{

                hidden: true,
                soratable: false,
                key: true,
        },
                subGrid: true,
                subGridRowExpanded: function (subgridId, rowId) {

                var currentRow = $(gridSelector).jqGrid('getRowData', rowId);
                var idDiscount = currentRow.idDiscount;
                var subgridTableId, pagerId;
                subgridTableId = subgridId + "_t";
                pagerId = "p_" + subgridTableId;
                $("#" + subgridId).html("<table id='" + subgridTableId + "' class='scroll'></table><div id='" + pagerId + "' class='scroll'></div>");
                jQuery("#" + subgridTableId).jqGrid({
        url: '',
                editurl: 'default.aspx?action=SubGrid',
                datatype: 'json',
                postData: {
                action: "SubGrid",
                        idDiscount: rowId

如果您使用 jqGrid 的subgrid as grid 功能，那么您实现了subGridRowExpanded 回调。回调的第二个参数是父网格的id。如果您在主网格中使用idPrefix（建议确保您没有重复的id），您可以使用$.jgrid.stripPref 剪切id 前缀并获得纯idDiscount 值。

在使用表单编辑的情况下，您可以使用onclickSubmit 回调来扩展将在编辑期间发布到服务器的数据。 onclickSubmit 回调的确切用法取决于您如何使用表单编辑。下面的代码片段仅显示了您可以做什么的主要思想

subGridRowExpanded: function (subgridDivId, rowId) {
    var mainGridPrefix = $(this).jqGrid("getGridParam", "idPrefix"),
        pagerId = subgridDivId + "_p",
        $subgrid = $("<table id='" + subgridDivId + "_t'></table><div id='" +
                      pagerId + "'></div>"),
        pureRowId = $.jgrid.stripPref(mainGridPrefix, rowId),
        addEditOptions = {
            onclickSubmit: function () {
                return { idDiscount: pureRowId };
            }
        };

    $subgrid.appendTo("#" + $.jgrid.jqID(subgridDivId));
    $subgrid.jqGrid({
        colModel: [
            { name: "cdDiscount", key: true, editable: true,
                editrules: { required: true } }
        ],
        pager: pagerId,
        ....
    }).jqGrid("navGrid", pagerId, {}, addEditOptions, addEditOptions);

onclickSubmit回调返回的数据应该是对象，其属性将与发布到服务器的主要数据相结合。返回{idDiscount: rowId} 只会添加idDiscount 参数和父网格行的rowid。
