附件信息

获取每条数据的附件信息，首先监听每一行数据，再给每条数据获取附件信息，如图

在控制器这边把附件信息查询出来，代码如下

public ActionResult SelectRoomRateAgreement(LayuiTablePage layuiTablePage, int RoomRateAgreements)
  {
   var listRoom = from tbRoom in myModel.S_RoomRateAgreement

                  join tbUint in myModel.S_AgreementUnit on tbRoom.AgreementUnitID equals tbUint.AgreementUnitID

                  join tbR in myModel.S_RoomCategory on tbRoom.RoomCategoryID equals tbR.RoomCategoryID

                  orderby tbRoom.RoomRateAgreementID descending //倒叙排序

                  where tbRoom.AgreementUnitID == RoomRateAgreements

                  select new RoomRates
                  {
                      RoomRateAgreementID = tbRoom.RoomRateAgreementID,//房价协议表

                      RoomCategoryName = tbR.RoomCategoryName,//房类

                      DisperseGuestPrice = tbR.DisperseGuestPrice,//实际房价

                      AgreementRoomRate = tbRoom.AgreementRoomRate,//协议房价

                      Remark = tbRoom.Remark,//备注                            

                      AgreementUnitID = tbUint.AgreementUnitID,//协议单位ID

                       RoomCategoryID = tbR.RoomCategoryID//房类ID
                    };

        var intTotalRow = listRoom.Count();//获取总行数
        List<RoomRates> list = listRoom
        .Skip(layuiTablePage.GetStartIndex())
        .Take(layuiTablePage.limit)
        .ToList();

        //调用分页封装类

        LayuiTableData<RoomRates> layuiTableData = new LayuiTableData<RoomRates>();

        layuiTableData.count = intTotalRow;//行总数

        layuiTableData.data = list;//具体显示数据

        return Json(layuiTableData, JsonRequestBehavior.AllowGet);
    }

在视图这边写获取附件的信息，代码如下

 //监听行单击事件  rowDouble
 layuiTable.on('row(tabAgreementUnit)', function (obj) {
  var data = obj.data;//获取点击行数据
  //标注选中样式
  obj.tr.addClass('layui-table-click').siblings().removeClass('layui-table-click');
  //***单击选中单选框 radio
  obj.tr.find('div.layui-unselect.layui-form-radio')[1].click();
  //用户类型ID
  var RoomRateAgreement = data.AgreementUnitID;
  //协议单位查询附件
  tabRoomRateAgreements = layuiTable.reload('tabRoomRateAgreements', {
  url: '/DFJIUDIAN/DFjiudian/SelectRoomRateAgreement',//数据接口
  page: { curr: 1, },//重定向到第一页
  where: {
      //设置异步数据接口的额外参数，比如设置多条件查询的参数
       RoomRateAgreements: RoomRateAgreement
      }
  }) 
});

新增附件信息也必须要选中行的数据，不然新增不了，如图

显示此功能代码如下，在打开新增模态框那里插入此段代码，便能实现效果

   //tabAgreementUnit 即为基础参数 id 对应的值
     var checkStatus = layuiTable.checkStatus('tabAgreementUnit');
     //checkStatus.data.length  获取选中行数量，可作为是否有选中行的条件
     if (checkStatus.data.length == 1) {
      //获取选中行的协议单位id
      var agreementunit = checkStatus.data[0].AgreementUnitID;
      //设置隐藏域中的协议单位ID
      $('#formInsetRoomRateAgreement [name="AgreementUnitID"]').val(agreementunit);
            //打开模态框
            $("#modalInsetRoomRateAgreement").modal('show');//show 显示
        } else {
            layer.msg('请先选择协议单位', { icon: 0 });
        }
