如何检测Iframe视频已在reactjs中结束

import React, { Component } from 'react';

class VideoPlayer extends Component {
  constructor(props) {
    super(props);
    this.state = {
      isVideoEnded: false
    };
  }

  handleVideoLoad = () => {
    this.setState({ isVideoEnded: false });
  }

  handleVideoEnd = () => {
    this.setState({ isVideoEnded: true });
  }

  render() {
    const { isVideoEnded } = this.state;

    return (
      <div>
        <iframe
          src="https://www.example.com/video"
          onLoad={this.handleVideoLoad}
          onEnded={this.handleVideoEnd}
        />
        {isVideoEnded && <p>视频已结束</p>}
      </div>
    );
  }
}

export default VideoPlayer;
