我想显示HTML5音频元素的当前时间和持续时间。我已经在互联网上搜索了很久，但找不到一个可行的脚本，可以让我显示音频文件的长度以及当前的时间，例如1:35 / 3:20。
有任何想法吗？:)
HTML5显示音频当前时间

1尝试使用audio.currentTime，看看有没有反应？我不确定它是否有效。 - c2h2
我该如何添加它？ - Lenny Magico
我该怎么添加呢？<script type="text/javascript">audio.currentTime</script>？ - Lenny Magico

这是一个例子：
<audio id="track" src="http://upload.wikimedia.org/wikipedia/commons/a/a9/Tromboon-sample.ogg"
ontimeupdate="document.getElementById('tracktime').innerHTML = Math.floor(this.currentTime) + ' / ' + Math.floor(this.duration);">
<p>Your browser does not support the audio element</p>
</audio>
<span id="tracktime">0 / 0</span>
<button onclick="document.getElementById('track').play();">Play</button>
这应该可以在Firefox和Chrome中工作，对于其他浏览器，您可能需要添加备用编码。

我无法在我的JS中绑定
ontimeupdate，我该怎么做？ - ArturoAtharva Johri，只需在ontimeupdate函数中使用一个函数并在该函数中处理您的内容。 - yourkishore
有没有办法让这段代码适用于Blob URL以播放MP3？ - user1788736

这是一个简单的用法。请记住，HTML5元素仍在开发中，因此任何内容都可能改变：
audio = document.getElementsByTagName("audio")[0];
//functions
audio.load();
audio.play();
audio.pause();
//properties
audio.currentSrc
audio.currentTime
audio.duration
这里有一个参考资料：HTML5音频
当音频播放时，要想获取当前时间，你必须附加timeupdate事件，并在回调函数中更新当前时间。

1你不觉得很有趣吗？除非你写出了提问者想要的代码，否则你的答案就不正确。好答案。 - clamchoda
我不想去碰 HTML5 直到它正式发布。太多需要调试的浏览器，哈哈 =D 谢了伙计。 - KJYe.Name
1我并不是说他的答案是错的，只是我不太懂JS和HTML 5音频对我来说是新的，所以我不太明白该怎么做 :) - Lenny Magico
需要一段时间才能轻松地将所有这些不同的组件放在一起。我知道当我刚开始时，仅仅展示这个并不能帮助我理解代码如何编写。 - Jared Dunham

除了 math.floor() 得到的秒数没有转换为适当的时间值之外，robertc 的版本可以正常工作。
以下是我的函数，当 ontimeupdate 被调用时它会被执行：
<audio id='audioTrack' ontimeupdate='updateTrackTime(this);'>
Audio tag not supported in this browser</audio>
<script>
function updateTrackTime(track){
var currTimeDiv = document.getElementById('currentTime');
var durationDiv = document.getElementById('duration');
var currTime = Math.floor(track.currentTime).toString();
var duration = Math.floor(track.duration).toString();
currTimeDiv.innerHTML = formatSecondsAsTime(currTime);
if (isNaN(duration)){
durationDiv.innerHTML = '00:00';
}
else{
durationDiv.innerHTML = formatSecondsAsTime(duration);
}
}
</script>
我修改了formatSecondsAsTime()函数，原本是从这里找来的：
function formatSecondsAsTime(secs, format) {
var hr = Math.floor(secs / 3600);
var min = Math.floor((secs - (hr * 3600))/60);
var sec = Math.floor(secs - (hr * 3600) - (min * 60));
if (min < 10){
min = "0" + min;
}
if (sec < 10){
sec = "0" + sec;
}
return min + ':' + sec;
}

ES6
const audio = new Audio();
audio.src = document.querySelector('#audio').src;
audio.play();
audio.addEventListener('timeupdate', (event) => {
const currentTime = Math.floor(audio.currentTime);
const duration = Math.floor(audio.duration);
}, false);

当您使用audio.duration()时，它会以秒为单位给出结果。您只需要将其转换为分钟和秒。这里有代码演示，希望能对您有所帮助。
song.addEventListener('timeupdate',function (){
var duration = song.duration; //song is object of audio. song= new Audio();
var sec= new Number();
var min= new Number();
sec = Math.floor( duration );
min = Math.floor( sec / 60 );
min = min >= 10 ? min : '0' + min;
sec = Math.floor( sec % 60 );
sec = sec >= 10 ? sec : '0' + sec;
$("#total_duration").html(min + ":"+ sec); //Id where i have to print the total duration of song.
});
这段代码适用于总时长。要获取当前时间，只需使用song.currentTime;代替song.duration;即可，整个代码保持不变。

是的！非常感谢。这是唯一对我有效的答案 :) - Andri

对于那些想在jQuery中实现timeupdate的人。
<audio id="myAudio">
<source src='test.mp3' type="audio/mp3" />
</audio>
$("audio#myAudio").get(0).addEventListener("timeupdate",function(){
// do your stuff here
});

this.player = new Audio(item.url)
this.player.play()
this.player.addEventListener('timeupdate', (event) => {
const currentTime = Math.floor(this.player.currentTime);
const duration = Math.floor(this.player.duration);
this.barWidth = (currentTime*100)/duration
}, false);

这个问题已经有多个答案和一个被接受的答案了。您能否通过编辑您的答案解释一下它与其他答案的不同之处呢？同时也要知道，仅有代码的答案在长期内是没有用处的。 - 7uc1f3r
我正在寻找一个仅使用JS且不利用DOM的答案。感谢您发布这个！ - TK421

或者您可以使用控件
用户可以使用控件来控制音频播放，包括音量、快进、暂停/恢复播放等。

关于 TypeScript：
formatTime(seconds: number): string {
let minutes: any = Math.floor(seconds / 60);
let secs: any = Math.floor(seconds % 60);
if (minutes < 10) {
minutes = '0' + minutes;
}
if (secs < 10) {
secs = '0' + secs;
}
return minutes + ':' + secs;
}
记得用常量替换魔数。这是一个例子。
