此链接不包含撤消选项实现，但您可以考虑使用此背后的逻辑。

< blockquote>不进行物理删除而是进行逻辑删除。在表结构中添加一列，如IS_DELETE或其他东西。当用户删除某些内容而不是进行物理删除时，只需将此行的IS_DELETE标记为1.所有搜索都应该知道此IS_DELETE列。

This link does not contains undo option implementation, but You could consider using the logic behind this.

Instead of doing a physical delete do a logical delete. Put a column in your tables structure like IS_DELETE or some thing. When a user delete something then instead of doing a physical delete just mark IS_DELETE of this row as 1. All your searches should be aware of this IS_DELETE column.
