如何在react中过滤对象？

import React, { Component } from 'react';

class ObjectFilter extends Component {
  constructor(props) {
    super(props);
    this.state = {
      objects: [
        { id: 1, name: 'Object 1' },
        { id: 2, name: 'Object 2' },
        { id: 3, name: 'Object 3' },
      ],
      filter: '',
    };
  }

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

  render() {
    const { objects, filter } = this.state;
    const filteredObjects = objects.filter((obj) =>
      obj.name.toLowerCase().includes(filter.toLowerCase())
    );

    return (
      <div>
        <input
          type="text"
          value={filter}
          onChange={this.handleFilterChange}
          placeholder="Enter filter keyword"
        />
        <ul>
          {filteredObjects.map((obj) => (
            <li key={obj.id}>{obj.name}</li>
          ))}
        </ul>
      </div>
    );
  }
}

export default ObjectFilter;
