根据子组件中更改的父组件状态在父组件上执行代码

import React, { useState } from 'react';

const ParentComponent = () => {
  const [parentState, setParentState] = useState('');

  const handleStateChange = (newState) => {
    setParentState(newState);
    // 在这里执行需要在父组件中执行的代码
  };

  return (
    <div>
      <ChildComponent onStateChange={handleStateChange} />
    </div>
  );
};

import React from 'react';

const ChildComponent = ({ onStateChange }) => {
  const handleClick = () => {
    // 在这里执行子组件中更改父组件状态的代码
    const newState = 'New State';
    onStateChange(newState);
  };

  return (
    <button onClick={handleClick}>Change Parent State</button>
  );
};
