在没有JQuery的React组件中显示N个列表项

import React, { Component } from 'react';

class List extends Component {
  constructor(props) {
    super(props);
    this.state = {
      items: []
    };
  }

  componentDidMount() {
    // 异步请求或其他方式获取列表项的数据
    // 示例：假设通过API获取数据
    fetch('https://api.example.com/items')
      .then(response => response.json())
      .then(data => {
        this.setState({ items: data });
      })
      .catch(error => {
        console.error('Error:', error);
      });
  }

  render() {
    return (
      <div>
        {this.state.items.map(item => (
          <div key={item.id}>{item.name}</div>
        ))}
      </div>
    );
  }
}

export default List;

import React, { Component } from 'react';
import List from './List';

class App extends Component {
  render() {
    const numberOfItems = 10; // 需要显示的列表项数量
    const items = Array.from({ length: numberOfItems }, (_, index) => ({
      id: index,
      name: `Item ${index + 1}`
    }));

    return (
      <div>
        <List items={items} />
      </div>
    );
  }
}

export default App;
