喜歡聽音樂的小伙伴們的福利來了,今天呢!小編和大家講講有關(guān)于:“HTML5自定義mp3播放器案例分享!”這方面的相關(guān)內(nèi)容,希望對(duì)于正在學(xué)習(xí)這方面內(nèi)容的小伙伴們有所幫助!

audio對(duì)象

src兼容.ogg .wav .mp3:

<audio controls src='data/imooc.wav'></audio>

width autoplay loop muted靜音:

<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();
        };

暫停pause()

pauseNode.onclick = function(){
                myAudio.pause();
            };

當(dāng)前播放的時(shí)間currentTime

音頻總時(shí)長(zhǎng)duration;

 //返回音頻的總長(zhǎng)度
            myAudio.addEventListener('canplay',function(){
                durationNode.innerHTML = myAudio.duration;
            });
            //更新當(dāng)前播放的時(shí)間
            setInterval(function(){
                currentNode.innerHTML = myAudio.currentTime;
            },100);

音頻源currentSrc:

var myAudio = new Audio();
        myAudio.src = 'data/imooc.mp3';
        console.log(myAudio.currentSrc);

loop循環(huán)

myAudio.loop = true;

音頻播放結(jié)束ended

myAudio.addEventListener('ended',function(){
            console.log('音頻播放結(jié)束');
            console.log(myAudio.ended)
        });

重新加載

  load=adBtn.onclick = function(){
myAudio.load();        };

跳轉(zhuǎn)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設(shè)置當(dāng)前播放速度

           myAudio.playbackRate = '15';
 console.log(myAudio.playbackRate)

全屏requestFullScreen

 btnScreen.onclick = function(){
            myAudio.webkitRequestFullScreen();
        }

loop 循環(huán)

 myAudio.loop = true;

volumechange音量改變

 

            myAudio.addEventListener('volumechange',function(){   console.log('音頻的聲音改變了')        });

timeupdate音頻正在播放狀態(tài):

 myAudio.addEventListener('timeupdate',function(){
            console.log('音頻正在播放中...')
        })
