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(); };
當前播放的時間currentTime
音頻總時長duration
//回傳音頻的總長度 myAudio.addEventListener('canplay',function(){ durationNode.innerHTML = myAudio.duration; }); //更新當前播放的時間 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回圈
myAudio.loop = true;
音頻播放結束ended
myAudio.addEventListener('ended',function(){
console.log('音頻播放結束');
console.log(myAudio.ended)
});
重新加載
loadBtn.onclick = function(){ myAudio.load(); };
跳轉到新的播放位置seeked / seeking
myAudio.addEventListener('seeked',function(){
console.log('seeked');
});
myAudio.addEventListener('seeking',function(){
console.log('seeking');
sekingNum++;
seekingNum.innerHTML = sekingNum;
});
playbackRate設定當前播放速度
myAudio.playbackRate = '15';
console.log(myAudio.playbackRate)
全屏requestFullScreen
btnScreen.onclick = function(){ myAudio.webkitRequestFullScreen(); }
loop 回圈
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
myAudio.addEventListener('timeupdate',function(){
console.log('音頻正在播放中...')
})
