推荐答案

由于您说的是基于Javascript的客户端树状视图，因此我可以放心地假设操作(添加，编辑，删除)可以在客户端站点上处理也(操作的至少一部分).

现在，在添加/编辑节点时，您需要使用Javascript将所有节点置于同一级别.将其存储在数组中以供以后比较或直接比较同一个名称.如果发现已经存在相同的名称，则不要继续操作并向用户显示有效的消息/提示.

Since you said it''s Javascript based client side treeview, I can safely assume the operations(Add, Edit, Delete) can be handled on client site too (atleast part of operation).

Now, at the time of adding/editing a node, you need to get all the nodes at the same level using Javascript. Store it in an array to compare later or directly compare for same name. If you find same name already existing then don''t continue the operation and show the valid message/prompt to the user.
