配置Redux-undo 以使其能够正确地工作需要几个关键步骤:初始化 Redux-undo、创建中间件并将其集成到 Redux 中。具体来说,你需要设置好中间件,以便它能够在用户执行操作时保存状态快照,并在用户请求撤销或重做操作时恢复这些快照。 初始化 Redux-undo 为了初始化 Redux-undo,你需要确保它被正确地集成到 Redux 中。...
Redux-undo 的核心是记录用户进行的所有操作,并允许用户撤销这些操作。每当一个 action 分发到 store 时,Redux-undo 会将其存储在一个历史记录中。用户可以浏览这个历史记录,并撤销或重做操作。 Redux-undo 使用一个特殊的类型@@redux-undo/UNDO和@@redux-undo/REDO来表示用户想要撤销或重做某个操作。这两个类型由...

Redux-undo功能是对Redux应用状态管理的扩展,它在应用程序状态发生变化时自动记录这些变化,以便用户能够撤销(undo)或重做(redo)操作。实现这一功能通常涉及两个关键部分: 状态监听器:监控应用状态的变化。 历史记录:记录状态变化的历史,并提供撤销和重做操作。
