javascript - 剑道在网格下拉菜单中更新页面上的任何点击

Question

我们已经在我们的应用程序中将我们的 Kendo JS 从 2.1008 升级到了 2.516。

我正在使用剑道网格的网格下拉编辑功能。

在以前的版本（2.1008）中，当我们单击网格单元格时，下拉加载并且仅当单击新的下拉列表项时update 才会触发剑道网格事件。

在当前的升级版本（2.516）中，当我们单击网格单元格时，会加载下拉列表，当您单击页面上除下拉列表之外的任何位置时，update会触发该事件。即，即使我没有更改（未单击）任何下拉列表项，网格也会更新，尽管它与以前的值相同（显示不必要的“成功更新”消息）。

请在下面找到任何点击（屏幕上的任何位置）都会触发的代码，即使下拉菜单没有更改。

            MyProject.Base.SearchFilter.Options.SortColumn = columname;
            MyProject.Base.SearchFilter.Options.SortOrder = data.sort[0].dir;
          } else {
            var grid = $("#ResultsGrid").data("kendoGrid");
            var columns = grid.columns;
            $(columns).each(function(index, value) {

              }
            });
            MyProject.Base.SearchFilter.Options.SortOrder = data.sort[0].dir;
          }
        }
      } else {
        if (somecondition) {
          MyProject.Base.SearchFilter.Options.SortColumn = null;
          MyProject.Base.SearchFilter.Options.MultipleSort = 'Server.ServerName ascending;DEPLOYMENT_SEQUENCE ascending';
        }
      }
      if (operation == "read") {

        if (MyProject.Base.SearchFilter.Options.SortColumn == 'ServerName') {
          MyProject.Base.SearchFilter.Options.SortColumn = 'Server.ServerName';
        }
        var inputvar = {
          'filter': MyProject.Base.SearchFilter
        };
        return JSON2.stringify(inputvar)
      }
      if (operation == "update") {
        debugger
        if (data != null) {
          var myId = data.MyId;
          var updateValue = data[KendoDeployment.EditFieldName];
          switch (KendoDeployment.EditFieldName) {
            case "MyColumnAttributes":
              updateValue = data[KendoDeployment.EditFieldName].UserId;
              KendoDeployment.EditFieldName = "MyColumn";
              break;

            case "MyColumn":
              updateValue = data["MyColumnAttributes"].UserId;
              KendoDeployment.EditFieldName = "MyColumn";
          };
          return JSON2.stringify({
            'MyId': myId,
            "updateValue": updateValue,
            "updateField": KendoDeployment.EditFieldName
          });
        }
      }
    }
  }
})

上述脚本中为任何点击事件调用的代码是

if (operation == "update") {
  debugger
  if (data != null) {
    var myId = data.MyId;
    var updateValue = data[KendoDeployment.EditFieldName];
    switch (KendoDeployment.EditFieldName) {
      case "MyColumnAttributes":
        updateValue = data[KendoDeployment.EditFieldName].UserId;
        KendoDeployment.EditFieldName = "MyColumn";
        break;

      case "MyColumn":
        updateValue = data["MyColumnAttributes"].UserId;
        KendoDeployment.EditFieldName = "MyColumn";
    };
    return JSON2.stringify({
      'MyId': myId,
      "updateValue": updateValue,
      "updateField": KendoDeployment.EditFieldName
    });
  }
}

有人可以指出我必须在哪里进行更改以解决此问题吗？
