喜欢听音乐的小伙伴们的福利来了,今天呢!小编和大家讲讲有关于:“HTML5自定义mp3播放器案例分享!”这方面的相关内容,希望对于正在学习这方面内容的小伙伴们有所帮助!

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

  load=adBtn.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...')
        })
