在React.js中过滤

const data = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Bob' }
];

const filteredData = data.filter(item => item.name.startsWith('J'));

console.log(filteredData);
// 输出：[{ id: 1, name: 'John' }, { id: 2, name: 'Jane' }]

import React, { useState } from 'react';

const data = [
  { id: 1, name: 'John' },
  { id: 2, name: 'Jane' },
  { id: 3, name: 'Bob' }
];

const FilteredList = () => {
  const [filter, setFilter] = useState('');

  const filteredData = data.filter(item => item.name.includes(filter));

  return (
    <div>
      <input type="text" value={filter} onChange={e => setFilter(e.target.value)} />
      <ul>
        {filteredData.map(item => (
          <li key={item.id}>{item.name}</li>
        ))}
      </ul>
    </div>
  );
};

export default FilteredList;
