如何获取react，js上选中的单选按钮的值？

import React, { useState } from 'react';

function MyComponent() {
  const [selectedValue, setSelectedValue] = useState('');

  // 其他组件代码...

  return (
    <div>
      <input
        type="radio"
        value="option1"
        checked={selectedValue === 'option1'}
        onChange={(e) => setSelectedValue(e.target.value)}
      />
      <label>Option 1</label>

      <input
        type="radio"
        value="option2"
        checked={selectedValue === 'option2'}
        onChange={(e) => setSelectedValue(e.target.value)}
      />
      <label>Option 2</label>
    </div>
  );
}

function MyComponent() {
  // ...

  const handleFormSubmit = (e) => {
    e.preventDefault();
    console.log('Selected value:', selectedValue);
  };

  return (
    <div>
      {/* 单选按钮代码... */}

      <form onSubmit={handleFormSubmit}>
        <button type="submit">Submit</button>
      </form>
    </div>
  );
}
