ReactJS:在不知道孩子状态的情况下统计父类中查看过的孩子(从孩子那里收到)

// 父组件
import React, { useState } from 'react';
import ChildComponent from './ChildComponent';

function ParentComponent() {
  const [childStatus, setChildStatus] = useState('');

  const handleChildStatus = (status) => {
    setChildStatus(status);
  };

  return (
    <div>
      <ChildComponent onStatusChange={handleChildStatus} />
      <p>孩子组件的状态：{childStatus}</p>
    </div>
  );
}

export default ParentComponent;

// 孩子组件
import React, { useState } from 'react';

function ChildComponent({ onStatusChange }) {
  const [status, setStatus] = useState('');

  const handleClick = () => {
    const newStatus = '已查看';
    setStatus(newStatus);
    onStatusChange(newStatus);
  };

  return (
    <div>
      <button onClick={handleClick}>点击查看</button>
      <p>孩子组件的状态：{status}</p>
    </div>
  );
}

export default ChildComponent;
