我已阅读此帖:How can I return a class from a TypeScript function?
在上面链接的帖子中,此工作代码显示为答案:
export class Foo {} // Foo is exported
export let factory = () : Foo => { // it could be return type of export function
return Foo
};
我目前的代码是这样的:
export class SimpleElement extends React.Component<any, any> {}
export let test = (): SimpleElement => {
return SimpleElement;
};
它给出了错误:
[ts]
Type 'typeof SimpleElement' is not assignable to type 'SimpleElement'.
Property 'setState' is missing in type 'typeof SimpleElement'.
我在这里查看了setState错误(Reactj, typescript Property 'setState' is missing in type),但答案似乎并没有特别有用。
答案 0 :(得分:0)
想出来。使用typeof。
export class SimpleElement extends React.Component<any, any> {}
export let test = (): typeof SimpleElement => {
return SimpleElement;
};
