我们先来看下最终的实现效果：

（学习视频分享：html5视频教程）

1、HTML代码

<div id="music">
    <div id="container">
        <h3 id="musicName">一月，银装轻舞-紫竹笛韵</h3>
        <img src="image/一月，银装轻舞-紫竹笛韵.jpg" id="musicImg">
        <audio src="./music/一月，银装轻舞-紫竹笛韵.mp3" controls id="audio"></audio>
        <div class="btn">
            <button id="play">play</button>
            <button id="pause">pause</button>
            <button id="prev">prev</button>
            <button id="next">next</button>
        </div>
    </div>
</div>

2、播放暂停切换效果实现

// 播放
play.onclick = function(){
    if(audio.paused){
        audio.play();
    }
}
  
// 暂停
pause.onclick = function(){
    if(audio.played){
        audio.pause();
    }
}

自动切换下一首

audio.addEventListener('ended',function(){
    next.onclick();
},false);

3、歌曲切换时歌曲图片与当前背景也随着改变

// 上一首
prev.onclick = function(){
    num = (num + len - 1) % len;
    audio.src = './music/' + music[num] + '.mp3';
    musicName.innerHTML = music[num];
    bgImage.style.backgroundImage = 'url(./image/' + music[num] + '.jpg)';
    musicImg.src = './image/' + music[num] + '.jpg';
    audio.play();
}
  
// 下一首
next.onclick = function(){
    num = (num + 1) % len;
    audio.src = './music/' + music[num] + '.mp3';
    musicName.innerHTML = music[num];
    bgImage.style.backgroundImage = 'url(./image/' + music[num] + '.jpg)';
    musicImg.src = './image/' + music[num] + '.jpg';
    audio.play();
}

4、实现背景图片透明，内容不透明效果

#music {
    width: 500px;
    height: 500px;
    border-radius: 10px;
    margin: 20px auto;
    position: relative;
    background: url(./image/一月，银装轻舞-紫竹笛韵.jpg) no-repeat;
    background-size: cover;
    text-align: center;
}
#container {
    position: absolute;
    left: 0;
    right: 0;
    top: 0;
    bottom: 0;
    width: 500px;
    height: 500px;
    text-align: center;
    background:rgba(255,255,255,0.6);
}
