在TypeScript中,你可以使用泛型和接口来定义组件的children属性。例如: 代码语言:txt 复制 import React from 'react'; interface MyComponentProps { // 其他属性... children?: React.ReactNode; // 使用React.ReactNode来表示children可以是任何React节点 } const MyComponent: React.FC<...
Declaring thechildrenprop asReactNodeis a perfectly viable option, but if you want to trim your code even further, you can useReact.FC.React.FCis a standard type for components written using the arrow function. As you probably guessed,FCstands for “Functional Component. " React.FC React.FCa...
它将接受您想要传递给children以外的组件的属性的类型参数。组件的返回类型可以是React.ReactNode。
Error 这个JSX标记的'children'属性需要'never'类型,它需要多个子元素,但只有一个子元素是provided.ts(2745) 没有与此呼叫匹配的重载。这个JSX标记的'children'属性需要'never'类型,它需要多个子元素,但只有一个子元素是provided.ts(2769) 我不确定我的代码有什么问题,因为我认为我遵循了大多数建议。。发布于 9 ...

import { render } from "react-dom"; import "./styles.css"; type ButtonProps = { label?: string; children: React.ReactNode; }; type ButtonState = { isOn: boolean; }; function Button (props: ButtonProps) { const [state, setState] = React.useState<ButtonState>({ ...
React 16.8 带来的全新特性,使用函数式组件,即将替代class组件的写法; 解决的问题 1.组件很难复用状态逻辑,一般使用HOC或者render Props 2.复杂组件难以理解,尤其是生命周期函数 例如,获取props中的id,需要在 componentDidMount和 componentDidUpdate 中同时定义;监听函数也需要在 componentDidMounted和componentWillUnmoun...
However, the reason why you might want to use a generic type likeFCis that this comes with all the typings that you could possibly need for a function component. This includes, for example, the implicitchildrenproperty. Being a default prop of any React component, we don't need to add it...
Rationale Props are an important part of a React component's interface, but children can be as well. In applications it's not uncommon to want to restrict what kind of children a component will accept. Currently this enforcement has to b...
