获取jqGrid子表格内的ID

[风吹裤衩轻飞扬丶]

这样的jqGrid 怎么获取子表格选中的id。

$gridTable.jqGrid({
			autowidth: true,
			height: $(window).height() - 136.5,
			url: "",
			datatype: "json",
			colModel: [
				{ label: '时间', name: 'Times', index: 'Times', width: 100, align: 'left', sortable: true },
			],
			viewrecords: true,
			rowNum: 30,
			rowList: [30, 50, 100],
			pager: "#gridPager",
			sortname: 'Times',
			sortorder: 'desc',
			rownumbers: true,
			shrinkToFit: false,
			gridview: true,
			onSelectRow: function () {
				selectedRowIndex = $('#' + this.id).getGridParam('selrow');
			},
			gridComplete: function () {
				$('#' + this.id).setSelection(selectedRowIndex, false);
			},
			subGrid: true,
			subGridRowExpanded: function (subgrid_id, row_id) {
				var keyValue = $gridTable.jqGrid('getRowData', row_id)['Times'];
				var subgrid_table_id = subgrid_id + "_t";
				$("#" + subgrid_id).html("<table id='" + subgrid_table_id + "'></table>");
				$("#" + subgrid_table_id).jqGrid({
					url: "",
					postData: { queryJson: '{Time: "' + keyValue + '"}' },
					datatype: "json",
					height: "100%",
					colModel: [
						{ label: 'FID', name: 'Field_ID', index: 'Field_ID', width: 100, align: 'left', sortable: true, hidden: true },
					],
					sortname: 'Field_DayTime',
					sortorder: 'desc',
					caption: "子项目",
					rowNum: "1000",
					rownumbers: true,
					shrinkToFit: false,
					gridview: true,
