在移动浏览器中拖放播放音频

Play Audio on Drag and Drop in Mobile Browsers

我有一个可以拖放的网站,适用于计算机、平板电脑和手机。它使用 jQuery、jQuery UI 和 jQuery UI Touch Punch。拖动会导致播放一个简短的音频剪辑,就像放下一样。 This fiddle 有例子。

遗憾的是,音频在当前版本的 iOS Safari 和 Android Chrome 中无法正常工作。有办法解决这个问题吗?

此图解释了各种浏览器版本中的行为:

图片说明:

iOS Safari: 在iOS 8.4 及以下版本中,拖放音频同时播放。在iOS 9.0及以上版本中,拖放音频均不播放。

Android Chrome: 在51.0.2704.81版本中,拖放音频同时播放。在52.0.2743.98和55.0.2883.91版本中,拖放音频均不播放。 56.0.2924.87和63.0.3239.111版本,拖拽不播放,拖放播放。

这是代码,如果 fiddle 永远消失:

出于多种原因,为了改善用户体验,避免烦人的广告,现在在移动设备上播放音频受到很大限制。您可以详细阅读here.

现在您需要通过有效的用户手势事件来播放音频元素。这就是为什么您的放置事件有效但拖动事件无效的原因。

在这种情况下,点击事件是最可靠的。您所要做的就是先通过点击事件播放音频,这将激活音频,然后您可以在之后的任何事件中播放它。

在这种情况下,最佳做法是让用户在执行任何操作之前单击一个按钮并静默播放音频,或者只播放通常无声的最后一毫秒的音频。然后音频元素就可以正常工作了。

$("#ibutton").click(function(){
    enable_audio($('#audio-drag'));
    enable_audio($('#audio-drop'));
});

启用功能只播放最后一毫秒。

function enable_audio(el){
    var myaudio=el[0];
    if(el.data('audio_enabled'))return;
    myaudio.currentTime=myaudio.duration-1;
    myaudio.play().then(function(){myaudio.pause();myaudio.load();});
    el.data('audio_enabled',true);
}
