HTML5 audio start over
提问by ?mega
Having
拥有
var audio = new Audio("click.ogg")
I play the click sound when needed by
我在需要时播放点击声音
audio.play()
However, sometimes user is so fast that a browser does not play the audio at all (probably when still playing a previous playrequest). Is this issue related to preload?
但是，有时用户速度太快以至于浏览器根本不播放音频（可能还在播放之前的play请求时）。这个问题与预加载有关吗？
How can I force a browser to stop playing and start over? There is no stop, just pausein HTML5 audio component, correct? What workaround can be used here?
如何强制浏览器停止播放并重新开始？没有stop，只是pause在 HTML5 音频组件中，对吗？这里可以使用什么解决方法？
Update- Additional note:
更新- 附加说明：
I have multiple checkbox-like divelements with a touchendevent. When such event is triggered, the elements visually change, a sound is played and an internal variable is set accordingly. If user tap on these elements slowly, everything works nicely. If tap fast, the sound is often completely skipped...
我有多个类似复选框的div元素和一个touchend事件。当此类事件被触发时，元素在视觉上发生变化，播放声音并相应地设置内部变量。如果用户慢慢点击这些元素，一切都很好。如果快速点击，声音通常会完全跳过......

You can try this code:
你可以试试这个代码：
audio.currentTime = 0;
audio.play();
It looks like this is the simplest solution.
看起来这是最简单的解决方案。

This is the code I've been using and it's working for me:
这是我一直在使用的代码，它对我有用：
if(audioSupport.duration > 0 && !audioSupport.paused){
//already playing
audioSupport.pause();
audioSupport.currentTime = 0;
audioSupport.play();
}else{
//not playing
audioSupport.play();
}

I noticed that on Firefox, playing a sound again and again really fast (like a short ticking sound) will skip beats often. The best solution I got was to simply call cloneNodeand play each sound that way. Its not perfect (compared to Chrome where it sounds flawless):
我注意到在 Firefox 上，一次又一次地播放声音非常快（如短促的滴答声）会经常跳过节拍。我得到的最佳解决方案是简单地以cloneNode这种方式调用和播放每个声音。它并不完美（与听起来完美无瑕的 Chrome 相比）：
var audio = document.getElementById('myaudio');
setInterval(function() {
audio.cloneNode().play();
}, 100);

The only way i found how to play a short sound very quickly (so quick that the 2nd sound starts before the first ends) is to actually load 5 or 10 and if you have to play again but are already playing, just go to the next, which is not playing:
我发现如何非常快速地播放短声音（如此之快以至于第二个声音在第一个结束之前开始）的唯一方法是实际加载 5 或 10，如果您必须再次播放但已经在播放，只需转到下一个，没有播放：
var soundEls = [];//load 10 audios instead of 1
for(var i=0;i<10;i++){
var soundEl = document.createElement('audio');
soundEl.src = url;
soundEl.preload = 'auto';
$(this._soundEl).append(soundEl);
soundEls.push(soundEl);
}
var soundElIndex = 0;
return {play:function(){
var soundEl = soundEls[soundElIndex];
if(soundEl.duration > 0 && !soundEl.paused){
//already playing, switch to next soundEl
soundElIndex++;
if(!soundEls[soundElIndex]) soundElIndex=0;
soundEls[soundElIndex].play();
}else{
//not playing
soundEl.play();
}
}};
Result of this is you can actually play the same sound over itself.
这样做的结果是您实际上可以在其自身上播放相同的声音。
Probably not the right way to do it though.
虽然可能不是正确的方法。
