如何在Reactjs中获取select选项值的索引

import React, { useState } from 'react';

function MyComponent() {
  const [selectedIndex, setSelectedIndex] = useState(0);

  const handleSelectChange = (event) => {
    setSelectedIndex(event.target.selectedIndex);
  };

  return (
    <select onChange={handleSelectChange}>
      <option value="option1">Option 1</option>
      <option value="option2">Option 2</option>
      <option value="option3">Option 3</option>
    </select>
  );
}

export default MyComponent;
