React.ComponentClass<Props, State, Context>, 继承React.Component或者React.PureComponent,示例: const C: React.ComponentClass = xxxxx; const jsx = <C />; 元素泛型 对应的是React.ElementType<P>,等价的React.ReactType已被标记为“不
一如上面的讨论,因为 TypeScript 可根据传入的实际值解析泛型类型,所以<Foo<string> content={"hello"}></Foo>中string是可选的,这里只为展示,让你看到其实 React 组件还可以这么玩。 为了进一步理解泛型组件,再看下非泛型情况下上面的组件是长怎样的。 interfaceProps { content:string; } function Foo(props:P...
除此之外,函数类型还可以使用React.FunctionComponent<P={}>来定义,也可以使用其简写React.FC<P={}>,两者效果是一样的。它是一个泛型接口,可以接收一个参数,参数表示props的类型,这个参数不是必须的。它们就相当于这样: type React.FC<P = {}> = React.FunctionComponent<P> 最终的定义形式如下: interface ...
However, this class interface is generic, so we can pass an interface to it that contains the types of our propsComponent<TitleProps>. Type-safe state in class components We can also make our state type-safe by creating an interface for it and passing it as a parameter toComponent: import...

Generic table component props We are going to implement a generic table component. Here’s our generic props type: type Props<DataItem> = { data: DataItem[]; onRowClick: (item: DataItem) => void; }; We’ve chosen to name the type parameter DataItem which is the type of each item in...
React-Bootstrap replaced Bootstrap Javascriptwhile ditching resource-heavy dependencies like JQuery to build a comprehensive but simplistic React component library.

Note thatReact.ElementTypecan pass a generic for the type of attribute expected by the element. In this example, we have to pass it an object with anameproperty of type String, because that's theheadingadf37a630bc83a33cb7d32b9f386e40d--- property that the component receives. ...
