当你打开该 HTML 文件时，会自动触发 window.onload 事件，并调用 playRandomSong 函数播放随机歌曲。播放器会自动选择一个歌曲进行播放，在播放完一首歌曲后自动随机选择另一首歌曲继续播放

window.onload = function() {
var audio = document.getElementById("audioPlayer");
audio.addEventListener('ended', playRandomSong);
playRandomSong();
};
function playRandomSong() {
var songs = [
//这里填写音乐文件的URL,多个URL用换行符分割
];
var randomIndex = Math.floor(Math.random() * songs.length);
var audio = document.getElementById("audioPlayer");
audio.src = songs[randomIndex];
audio.play();
var currentSongUrl = document.getElementById("currentSongUrl");
currentSongUrl.textContent = "正在播放：" + songs[randomIndex];
}
