如何在React中用Hashtag替换文本中的word？

import React from 'react';

class HashtagReplace extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      text: '这是一个示例文本，包含要替换的单词。',
      word: '要替换的单词',
      hashtag: '#替换后的单词'
    };
  }

  render() {
    const { text, word, hashtag } = this.state;
    const replacedText = text.replace(new RegExp(word, 'g'), hashtag);

    return (
      <div>
        <p>原始文本：{text}</p>
        <p>替换后的文本：{replacedText}</p>
      </div>
    );
  }
}

export default HashtagReplace;

import React from 'react';
import HashtagReplace from './HashtagReplace';

class App extends React.Component {
  render() {
    return (
      <div>
        <h1>React中使用Hashtag替换文本中的单词</h1>
        <HashtagReplace />
      </div>
    );
  }
}

export default App;
