React.js从句子或段落中获取Youtube链接并将其转换为链接

import React from 'react';

class YoutubeLinkConverter extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      inputText: '',
      youtubeLinks: [],
    };
  }

  handleChange = (event) => {
    this.setState({ inputText: event.target.value });
  }

  convertLinks = () => {
    const { inputText } = this.state;
    const youtubeRegex = /(?:https?:\/\/)?(?:www\.)?youtu(?:be\.com\/watch\?v=|\.be\/)([\w\-\_]*)(&(amp;)?‌​[\w\?‌​=]*)?/g;
    const matches = inputText.match(youtubeRegex);
    if (matches) {
      this.setState({ youtubeLinks: matches });
    }
  }

  render() {
    const { inputText, youtubeLinks } = this.state;

    return (
      <div>
        <textarea value={inputText} onChange={this.handleChange} />
        <button onClick={this.convertLinks}>Convert</button>
        <ul>
          {youtubeLinks.map((link, index) => (
            <li key={index}>
              <a href={link} target="_blank" rel="noopener noreferrer">{link}</a>
            </li>
          ))}
        </ul>
      </div>
    );
  }
}

export default YoutubeLinkConverter;
