使用useState()修改对象数组

import React, { useState } from 'react';

const App = () => {
  const [data, setData] = useState([
    { id: 1, name: 'John' },
    { id: 2, name: 'Jane' },
    { id: 3, name: 'Mike' }
  ]);

  const updateName = (id, newName) => {
    // 使用map()函数创建一个新的对象数组，根据id匹配对应的元素进行修改
    const updatedData = data.map(item => {
      if (item.id === id) {
        return { ...item, name: newName };
      }
      return item;
    });

    setData(updatedData); // 更新数据
  };

  return (
    <div>
      {data.map(item => (
        <div key={item.id}>
          <span>{item.name}</span>
          <button onClick={() => updateName(item.id, 'New Name')}>Update Name</button>
        </div>
      ))}
    </div>
  );
};

export default App;
