无法在reactJS Typescript中获取输入值

import React, { useState } from 'react';

const MyComponent: React.FC = () => {
  const [inputValue, setInputValue] = useState('');

  const handleChange = (event: React.ChangeEvent<HTMLInputElement>) => {
    setInputValue(event.target.value);
  };

  return (
    <div>
      <input type="text" value={inputValue} onChange={handleChange} />
      <p>输入的值是：{inputValue}</p>
    </div>
  );
};

export default MyComponent;

import React, { useRef } from 'react';

const MyComponent: React.FC = () => {
  const inputRef = useRef<HTMLInputElement>(null);

  const handleClick = () => {
    if (inputRef.current) {
      const inputValue = inputRef.current.value;
      console.log('输入的值是：', inputValue);
    }
  };

  return (
    <div>
      <input type="text" ref={inputRef} />
      <button onClick={handleClick}>获取输入值</button>
    </div>
  );
};

export default MyComponent;
