如何在Typescript tsx中遍历React组件的子项？
以下是有效的jsx：
public render() {
return (
<div>
{React.Children.map(this.props.children,x => x.props.foo)}
</div>
);
}
但是,在Typescript中,x的类型是React.ReactElement< any>所以我无法获得道具.我需要做某种铸造吗？
However,in Typescript,the type of x is React.ReactElement so I have no access to props. Is there some kind of casting that I need to do?
是.也更喜欢断言一词.一个快速的：
React.Children.map(this.props.children,x => (x as any).props.foo)
