在React中过滤用户列表

import React, { Component } from 'react';

class UserList extends Component {
  constructor(props) {
    super(props);
    this.state = {
      users: [
        { id: 1, name: 'Alice' },
        { id: 2, name: 'Bob' },
        { id: 3, name: 'Charlie' },
      ],
      filterText: '',
    };
  }

  handleFilterTextChange = (event) => {
    this.setState({ filterText: event.target.value });
  }

  render() {
    const { users, filterText } = this.state;
    const filteredUsers = users.filter(user =>
      user.name.toLowerCase().includes(filterText.toLowerCase())
    );

    return (
      <div>
        <input
          type="text"
          value={filterText}
          onChange={this.handleFilterTextChange}
          placeholder="Filter users"
        />
        <ul>
          {filteredUsers.map(user => (
            <li key={user.id}>{user.name}</li>
          ))}
        </ul>
      </div>
    );
  }
}

export default UserList;
