使用react更新<select>

import React, { useState } from 'react';

function SelectExample() {
  const [selectedOption, setSelectedOption] = useState('');

  const handleChange = (event) => {
    setSelectedOption(event.target.value);
  };

  return (
    <div>
      <select value={selectedOption} onChange={handleChange}>
        <option value="">请选择</option>
        <option value="option1">选项1</option>
        <option value="option2">选项2</option>
        <option value="option3">选项3</option>
      </select>
      <p>你选择了: {selectedOption}</p>
    </div>
  );
}

export default SelectExample;

<select value={selectedOption} onChange={handleChange}>
  {/* 选项 */}
</select>

<select value={selectedOption} onChange={handleChange}>
  {options.map((option) => (
    <option key={option.value} value={option.value}>
      {option.label}
    </option>
  ))}
</select>
