React 中 使用 ts

import React from ‘react‘;
const Icon = ({ name, ...restProps}) => {
    return (
        <svg {...restProps}>
            <use xlinkHref={`#${name}`}/>
        </svg>
    );
};
export default Icon;

import * as React from ‘react‘;
import ReactDom from ‘react-dom‘;
import Icon from ‘./icon/icon‘;

const fn =  (e) => {
  console.log((e))
};

ReactDom.render(
  <Icon name=‘wechat‘/>, 
  document.getElementById(‘root‘)
);

import React from ‘react‘;

interface IconProps{
   name: string;
}

 const Icon: React.FunctionComponent<IconProps>  // React.FunctionComponent为对icon组件的类型测试，后面是传入的值的类型
=({ name, ...restProps})=> {
    return (
        <svg {...restProps}>
            <use xlinkHref={`#${name}`}/>
        </svg>
    );
};

export default Icon;

interface IconProps extends React.SVGAttributes<SVGElement> {
    name: string;
    onClick: React.MouseEventHandler<SVGElement>
}

const fn: React.MouseEventHandler<SVGAElement | SVGUseElement> = (e) => {
  console.log((e.target as HTMLDivElement))
};
