如何在HTML5中自定义一个mp3播放器？针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
audio对象
src兼容.ogg .wav .mp3
<audio controls src='data/imooc.wav'></audio>width autoplay loop muted静音
<audio controls src='data/imooc.wav' autoplay loop width='500' height='500' muted></audio>播放play()
var myAudio = new Audio(); myAudio.src = 'data/imooc.wav'; myAudio.play(); btn.onclick = function(){ myAudio.play(); };暂停pause()
pauseNode.onclick = function(){ myAudio.pause(); };当前播放的时间currentTime
音频总时长duration
//返回音频的总长度 myAudio.addEventListener('canplay',function(){ durationNode.innerHTML = myAudio.duration; }); //更新当前播放的时间 setInterval(function(){ currentNode.innerHTML = myAudio.currentTime; },100);音频源currentSrc
var myAudio = new Audio(); myAudio.src = 'data/imooc.mp3'; console.log(myAudio.currentSrc);loop循环
myAudio.loop = true;音频播放结束ended
myAudio.addEventListener('ended',function(){ console.log('音频播放结束'); console.log(myAudio.ended) });重新加载
loadBtn.onclick = function(){ myAudio.load(); };跳转到新的播放位置seeked / seeking
myAudio.addEventListener('seeked',function(){ console.log('seeked'); }); myAudio.addEventListener('seeking',function(){ console.log('seeking'); sekingNum++; seekingNum.innerHTML = sekingNum; });playbackRate设置当前播放速度
myAudio.playbackRate = '15'; console.log(myAudio.playbackRate)全屏requestFullScreen
btnScreen.onclick = function(){ myAudio.webkitRequestFullScreen(); }loop 循环
myAudio.loop = true;volumechange音量改变
myAudio.addEventListener('volumechange',function(){ console.log('音频的声音改变了') });timeupdate音频正在播放状态
myAudio.addEventListener('timeupdate',function(){ console.log('音频正在播放中...') })自定义mp3播放器
