您可以使用React.PropsWithChildren，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...
使用props.children的Typescript React功能组件是一种在React中传递子组件的技术。props.children是一个特殊的属性,它允许我们在父组件中嵌套子组件,并通过props将子组件传递给父组件。 在Typescript中,我们可以使用泛型来定义props.children的类型。例如,我们可以创建一个名为Props的接口,并使用React.ReactNode作为props....
type MyComponentProps = { className: string }; // Does not work. function MyComponent({ className, children }: MyComponentProps) { // children is not typed and TypeScript complains return <div className={className}>{children}</div>; } 但是使用React.FC将一切正常: // Works as expected: ...
type PropsWithChildren<P> = P & { children?: ReactNode };Instead of relying on PropsWithChildren, you can also type the children prop directly:import { ReactNode } from 'react' type FooProps = { name: 'foo' // look here children: ReactNode } export const Foo = (props: FooProps)...
import * as React from 'react'; import { render } from 'react-dom'; interface IProps<T> { collapsed: boolean; listOfData: T[]; displayData: (data: T, index: number) => React.ReactNode; } class CollapsableDataList<T> extends React.Component<IProps<T>> { render () { if (!this...

type Props = { children: React.ReactNode;};function Comp({ children }: Props) { return <div>{children}</div>;}function App() { return <Comp>{{}}</Comp>; // Runtime Error: Objects not valid as React Child!} 这是因为 ReactNode 包含 ReactFragment （它允许 {} ），修复这个会...
When I started using TypeScript with React, the first bump in the road was figuring out what type to use for thechildrenprop. That’s because there are several different types React provides for this. It didn’t help that I saw multiple projects using different types interchangeably. ...
children: React.ReactNode; }; type ButtonState = { isOn: boolean; }; class Button extends React.Component<ButtonProps, ButtonState>{ static defaultProps = { label: "Hello World!" }; state = { isOn: false }; toggle = () => this.setState({ isOn: !this.state.isOn }); ...
在此 <Button /> 组件中，我们为 Props 使用 type。每个 Props 上方都有简短的说明，以为其他开发人员提供更多背景信息。? 表示 Props 是可选的。children props 是一个 React.ReactNode 表示它还是一个 React 组件。通常，在 React 和 TypeScript 项目中编写 Props 时，请记住以下几点：始终使用 TSDoc 标记为...
