react 解决警告Warning

react 解决警告Warning: Each child in a list should have a unique “key” prop - 简书登录注册写文章首页下载APP会员IT技术react 解决警告Warning: Each child in a list should have a unique “key” prop黎明的叶子关注赞赏支持react 解决警告Warning: Each child in a list should have a unique “key” prop总结:react在循环元素的时候一定要加key值,有两个重要点。1.key值不可以重复。key值重复会发生意想不到的错误。所以一定要保证key的唯一性。我曾遇到过key值重复后,重复的key值会在组件被多次调用的时候保留下来。造成数据错乱。2.加key的地方是在循环的第一层元素上。

Context – React

Context – React为社区建设略尽绵薄之力!参与 2021 社区问卷调查!React文档教程博客社区v18.2.0 多语言GitHubContextContext 提供了一个无需为每层组件手动添加 props,就能在组件树间进行数据传递的方法。在一个典型的 React 应用中,数据是通过 props 属性自上而下(由父及子)进行传递的,但此种用法对于某些类型的属性而言是极其繁琐的(例如:地区偏好,UI 主题),这些属性是应用程序中许多组件都需要的。Context 提供了一种在组件之间共享此类值的方式,而不必显式地通过组件树的逐层传递 props。
