I have created a JS class to populate SG/Folder list view data, when items are modified.
(当修改项目时，我创建了一个JS类来填充SG / Folder列表视图数据。)
( As per Jaime's approach) Everything works great when I operate on items in the publication they're created in.(（ 根据Jaime的方法）当我在他们创建的出版物中操作项目时，一切都很有效。)
Ex: I open a component or page and the custom locked by column immediately updates and shows my user name.
(例如：我打开一个组件或页面， locked by列locked by的自定义会立即更新并显示我的用户名。)
However, when I go to a child publication and repeat that process, I get the window asking if I want to localize or edit the parent item.
(但是，当我转到子出版物并重复该过程时，我会看到窗口询问是否要本地化或编辑父项。)
If I select to edit the parent window, the code doesn't work.(如果我选择编辑父窗口，则代码不起作用。)
I haven't quite figured it out yet with initial debugging.(通过初始调试，我还没有完全理解它。)
Chrome seems to swallow the error, Firefox gives me a cryptic:(Chrome似乎吞下了这个错误，Firefox给了我一个神秘的含义：)

Does anyone have any initial ideas?
