html5结合javascript实现简易音乐播放器
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" alt="html5结合javascript实现简易音乐播放器" > <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);}
