javascript - Infragistics - 在代码中显示/隐藏列(不使用默认列选择器对话框)

转载作者：行者123 更新时间：2023-11-30 14:32:25

我已经实现了自定义列选择器对话框。当用户提交更改时，我有两个数组:

keysOfColumnsToShow (example: ['key1', 'key2', ...])
keysOfColumnsToHide (example: ['key3', 'key4', ...])

我已经调试过了， key 没问题。现在我尝试在代码中应用更改。为此，我使用 igGridHiding 方法:

$(".grid").igGridHiding("showMultiColumns", keysOfColumnsToShow)
$(".grid").igGridHiding("hideMultiColumns", keysOfColumnsToHide)

问题是在调用 igGridHiding 方法后，有些标题不在相应列之上，有些标题为空。

在不使用默认对话框的情况下，在代码中管理隐藏/显示列的正确方法是什么？

最佳答案

您能否提供有关您的场景的更多详细信息？我对此进行了调查并准备了一个示例，但未能成功复制您所描述的场景。

它按预期工作。你能修改下面的代码示例来演示吗？
