遍历子组件中的父数据(通过Ajax设置)

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

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

  useEffect(() => {
    fetchData();
  }, []);

  const fetchData = async () => {
    try {
      const response = await fetch('https://example.com/api/data');
      const jsonData = await response.json();
      setData(jsonData);
    } catch (error) {
      console.error('Error fetching data:', error);
    }
  };

  return (
    <div>
      <h1>Parent Component</h1>
      <ChildComponent data={data} />
    </div>
  );
};

export default ParentComponent;

import React from 'react';

const ChildComponent = ({ data }) => {
  return (
    <div>
      <h2>Child Component</h2>
      <ul>
        {data.map((item, index) => (
          <li key={index}>{item}</li>
        ))}
      </ul>
    </div>
  );
};

export default ChildComponent;
