you need to click the add button after clicking the row to complete the addition of the multi-level menu. After listening to the event with the layui of table.on, the data cannot be sent to the click event. How to implement 
 my code 
 var thisRowData; 
        table.on("row(table1)", function (obj){
            obj.tr.addClass("layui-table-click2").siblings().removeClass("layui-table-click2");
            var data = obj.data;
            var id = data.parentId;
            console.log(id);
            thisRowData(data);
          
        });
        window.openAddLayer = function(obj){
        function thisRowData(obj);
            layer.open({
                type:2,
                title:"/",
                area:["400px","500px"],
                fix:false,
                content:"add.html",
                success:function(layero,index){
                },
                error:function(layero,index){
                    errmsg(res);
                }
            })
        }
