使用javascript/react在网站上创建可格式化的文本框

import React, { useState } from 'react';

const FormattedTextBox = () => {
  const [text, setText] = useState('');

  const handleInputChange = (event) => {
    // 格式化逻辑
    const formattedText = event.target.value.toUpperCase();
    setText(formattedText);
  };

  return (
    <input type="text" value={text} onChange={handleInputChange} />
  );
};

export default FormattedTextBox;

import React from 'react';
import ReactDOM from 'react-dom';
import FormattedTextBox from './FormattedTextBox';

ReactDOM.render(<FormattedTextBox />, document.getElementById('root'));
