【问题描述】：

当 subGridRowExpanded 时我有一个 jqGrid 和 SubGrid，我想要在 SubGrid 为空时取消绑定事件展开行和图标展开行数据。当我将一行从其他网格拖到这个子网格时，我想再次为 subGridRowExpanded 绑定事件将图标展开行添加到网格。我该怎么做？

我在加载 gridComplete 时取消绑定事件 subGridRowExpanded：

function CreateOperationGrid(styleCode, styleSize, styleColorSerial, revNo) 
    Operation_Grid.jqGrid(
        datatype: "json",
        height: 250,
        width: null,
        shrinkToFit: false,
        rowNum: 100000,
        rownumbers: true,
        gridview: false,
        //==========================================
        url: "/OpsLink/GetOpDetail",
        caption: "Operation",
        postData: 
            styleCode: styleCode, size: styleSize, serial: styleColorSerial, revNo: revNo
        ,
        //mtype: 'POST',
        colModel: [
            
                name: "BenchmarkTime",
                index: "BenchmarkTime",
                width: 95,
                label: arrColname.BENCHMARKTIME,
                align: "center",
                search: false,
                sort: false
            ,
             name: "StyleCode", index: "StyleCode", hidden: true ,
             name: "StyleSize", index: "StyleSize", hidden: true ,
             name: "StyleColorSerial", index: "StyleColorSerial", hidden: true ,
             name: "RevNo", index: "RevNo", hidden: true ,
             name: "OpRevNo", index: "OpRevNo", hidden: true ,
             name: "NewPrevNo", index: "NewPrevNo", hidden: true 
        ],
        grouping: true,
        groupingView: 
            groupField: ["OpGroupName"],
            groupColumnShow: [false],
            groupCollapse: true,
            plusicon: "ace-icon fa fa-plus",
            minusicon: "ace-icon fa fa-minus"
        ,
        subGrid: true,
        subGridRowExpanded: function (subgridId, rowId) 
            var row = Operation_Grid.getRowData(rowId);
            var sCode = row.StyleCode;
            var subgridTableId = subgridId + "_t";
            jQuery("#" + subgridId).html("<table id='" + subgridTableId + "' class='scroll'></table>");
            jQuery("#" + subgridTableId).jqGrid(
                url: "/OpsLink/GetProtBomPattern?styleCode=" + sCode,
                datatype: "json",
                page: 1,
                colModel: [
                     label: arrOpChilName.OpRevNo, name: "OpRevNo", index: "OpRevNo", width: 80 ,
                     label: arrOpChilName.OpSerial, name: "OpSerial", index: "OpSerial", width: 80 ,
                     label: arrOpChilName.OpType, name: "OpType", index: "OpType", width: 80 ,
                     label: arrOpChilName.ConSumUnit, name: "ConSumUnit", index: "ConSumUnit", width: 80 ,
                     label: arrOpChilName.UnitConSumTion, name: "UnitConSumTion", index: "UnitConSumTion", width: 80 ,
                     label: arrOpChilName.PieceQty, name: "PieceQty", index: "PieceQty", width: 80 

                ],
                viewrecords: true,
                height: "100%",
                rownumbers: true,
                multiselect: true,
                pager: "#jqGridPager" + "_" + subgridId
            );
        ,
        subGridOptions: 
            plusicon: "ace-icon fa fa-plus",
            minusicon: "ace-icon fa fa-minus",
            openicon: "ui-icon-carat-1-sw",
            expandOnLoad: false,
            selectOnExpand: false,
            reloadOnExpand: false
        ,
        gridComplete: function () 
            Operation_Grid.find('tr[role="row"]').addClass("ui-droppable");
            $('td[aria-describedby="Operation_Grid_NewPrevNo"]').each(function () 
                var x = $(this).html();
                if (x === "&nbsp;") 
                    $(this).parent().find('td[aria-describedby="Operation_Grid_subgrid"]').unbind("click").html("");
                
            );
        
    );

我想再次注册活动：

Operation_Grid.find('tr[id="' + rowDropTo + '"]').find('td[aria-describedby="Operation_Grid_subgrid"]').bind("click").html('<a style="cursor:pointer;"><span class="ui-icon ui-icon-plus"></span></a>');

但是当我点击图标时它没有运行 subGridRowExpanded 功能。请帮忙，谢谢

【参考方案1】：

经过两天的研究，我一直像这样重新绑定 susses。

在将 pus 移除到数组中之前：

currChild[id] = $(this).parent().find('td[aria- describeby="Operation_Grid_subgrid"]').clone(true, true); $(this).parent().find('td[aria- describeby="Operation_Grid_subgrid"]').unbind("click").html("");

重新装箱。

Operation_Grid.find('tr[id="' + rowDropTo + '"]').find('td[aria- describeby="Operation_Grid_subgrid"]').replaceWith(currChild[rowDropTo]);

【参考方案2】：

如果您使用Guriddo jqGrid，请查看我们的demo example here

编辑：针对您的情况，另一种可能的解决方案是仅显示和隐藏图标（在绑定中单击的 href 标记），而不是绑定取消绑定事件。
