父组件中定义

子组件中触发回调传值

import { useState } from "react";
function Son(params) {const [count, setCount] = useState(0);function handleClick() {console.log(params, 'paramsparamsparamsparamsparamsparams');params.onClick(111)setCount(count + 1);}// console.log(params, 'paramsparams');return (<div>{params.count}<button onClick={handleClick}>Clicked {count} Son times</button></div>)
}
export default Son;
