下拉列表未显示在剑道网格 detailInit 网格的所有行中

在我的 detailInit 网格中向我的网格添加下拉列表时，我遇到了一个问题。当我选择一行时，下拉列表在那里，但是当我选择另一行时，下拉列表不会出现。

但是，如果我选择第三行，则会出现下拉列表，它们将出现在第二行和第一行中，但不会出现在第四行中。

为什么会发生这种情况以及如何修复它，以便无论我选择哪一行，所有行都将具有下拉列表？

var dropdownData = [{
    "CatalogID": 1,
    "NameVersion": "Catalog1"
  },
  {
    "CatalogID": 2,
    "NameVersion": "Catalog2"
  },
  {
    "CatalogID": 3,
    "NameVersion": "Catalog3"
  },
  {
    "CatalogID": 4,
    "NameVersion": "Catalog4"
  },
];

$(document).ready(function() {

  //#region Data

  var data2 = [{
      "RoomID": 1,
      "RoomName": "Room 1",
      "Areas": [{
        "id": 1,
        "AreaName": "Area 1"
      }, {

        "AreaName": "Area 10"
      }]
    },

您有多个具有相同 ID 的 DOM 元素，对于您创建具有相同 ID 的网格的每个细节单元格，因此在 dataBound 事件中您无法控制您选择的网格。

我认为，您应该将 detailCell 作为参数传递给 'abindCatalogDropDownInCellProcess' 函数以查找相应的输入，如下所示：

dataBound: function(w) {
      abindCatalogDropDownInCellProcess(e.detailCell);
    }
...

function abindCatalogDropDownInCellProcess(cell) {
  cell.find("td input.edit-area-catalog-dropdown").each(function(){})
}

工作示例。
