如何在react管理中过滤列表

import React, { Component } from 'react';

class FilteredList extends Component {
  constructor(props) {
    super(props);
    this.state = {
      listData: [...], // 列表数据
      filter: '', // 过滤条件
    };
  }

  handleFilterChange = (event) => {
    this.setState({ filter: event.target.value });
  }

  render() {
    const { listData, filter } = this.state;
    
    // 根据过滤条件进行过滤
    const filteredListData = listData.filter(item =>
      item.toLowerCase().includes(filter.toLowerCase())
    );

    return (
      <div>
        <input
          type="text"
          value={filter}
          onChange={this.handleFilterChange}
          placeholder="输入过滤条件"
        />
        
        <ul>
          {filteredListData.map(item => (
            <li key={item}>{item}</li>
          ))}
        </ul>
      </div>
    );
  }
}

export default FilteredList;
