如何跨多个HTML页面播放背景音频.

.audio-player {
  position: fixed;
  bottom: 0;
  left: 0;
  width: 100%;
  height: 50px;
  z-index: 9999;
}

// 创建音频播放器
var audioPlayer = document.createElement('audio');
audioPlayer.src = 'audio_file.mp3';
audioPlayer.loop = true;
audioPlayer.autoplay = true;
audioPlayer.controls = true;
audioPlayer.style.display = 'none';

// 将音频播放器添加到页面中
document.body.appendChild(audioPlayer);

const express = require('express');
const app = express();

app.use('/audio', express.static('path/to/audio_player.html'));

app.listen(3000, () => {
  console.log('Server started on port 3000');
});
