如何在ReactJS中将数据从子功能元件发送到父功能元件？

// 父功能组件
import React, { useState } from 'react';
import ChildComponent from './ChildComponent';

const ParentComponent = () => {
  const [data, setData] = useState('');

  // 定义回调函数，用于接收子功能组件发送的数据
  const handleDataFromChild = (childData) => {
    setData(childData);
  };

  return (
    <div>
      <h1>Data from Child: {data}</h1>
      <ChildComponent sendDataToParent={handleDataFromChild} />
    </div>
  );
};

export default ParentComponent;

// 子功能组件
import React from 'react';

const ChildComponent = ({ sendDataToParent }) => {
  const sendData = () => {
    const data = 'Hello from Child';
    // 调用父功能组件传递的回调函数，并传递数据作为参数
    sendDataToParent(data);
  };

  return (
    <div>
      <button onClick={sendData}>Send Data to Parent</button>
    </div>
  );
};

export default ChildComponent;
