根据视口高度将内容动态添加到引用的React子对象

import React, { useEffect, useState } from 'react';

const DynamicContent = () => {
  const [content, setContent] = useState('');

  useEffect(() => {
    const handleResize = () => {
      const viewportHeight = window.innerHeight;
      if (viewportHeight > 600) {
        setContent('显示的内容1');
      } else {
        setContent('显示的内容2');
      }
    };

    window.addEventListener('resize', handleResize);
    handleResize(); // 初始化时执行一次

    return () => {
      window.removeEventListener('resize', handleResize);
    };
  }, []);

  return <div>{content}</div>;
};

export default DynamicContent;
