如何使用扩展运算符在循环中使用setState()

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      items: [
        { id: 1, name: 'Item 1', checked: false },
        { id: 2, name: 'Item 2', checked: false },
        { id: 3, name: 'Item 3', checked: false }
      ]
    };
  }

  handleCheckboxChange = (itemId) => {
    this.setState(prevState => {
      const updatedItems = prevState.items.map(item => {
        if (item.id === itemId) {
          return { ...item, checked: !item.checked }; // 使用扩展运算符更新checked属性
        }
        return item;
      });

      return { items: updatedItems };
    });
  }

  render() {
    return (
      <div>
        {this.state.items.map(item => (
          <div key={item.id}>
            <input
              type="checkbox"
              checked={item.checked}
              onChange={() => this.handleCheckboxChange(item.id)}
            />
            <span>{item.name}</span>
          </div>
        ))}
      </div>
    );
  }
}
