Reactjs 反应钩组件重新加载
我正在构建一个typescript react应用程序，它有一个名为Accordion的子组件，当单击它时，它就会打开。打开时，它会呈现一个包含一些数据的表。这个手风琴是根据一个可以用选择器改变的组来制作的。我的问题是，当我通过我的手风琴组件更改这个组时，如果它被打开，我希望它关闭。我试图通过一个道具来关闭手风琴，但什么也没发生，我开始感到沮丧。如何重新加载此组件以关闭状态？这是我的密码： 这是我的手风琴组件：Reactjs 反应钩组件重新加载,reactjs,Reactjs,我正在构建一个typescript react应用程序，它有一个名为Accordion的子组件，当单击它时，它就会打开。打开时，它会呈现一个包含一些数据的表。这个手风琴是根据一个可以用选择器改变的组来制作的。我的问题是，当我通过我的手风琴组件更改这个组时，如果它被打开，我希望它关闭。我试图通过一个道具来关闭手风琴，但什么也没发生，我开始感到沮丧。如何重新加载此组件以关闭状态？这是我的密码： 这是我的手风琴组件： import React, { useState, useRef, Fragment
