推荐答案

您的问题是音频对象不支持'负荷'事件。

Your problem is that Audio objects don't support the 'load' event.

相反，有一个名为canplaythrough，这并不意味着它是满载的事件，但也足够它被加载，在目前的下载速率，这将是由轨道有足够的时间，通过发挥的时间内完成。

Instead, there's an event called 'canplaythrough' that doesn't mean it's fully loaded, but enough of it is loaded that at the current download rate, it will finish by the time the track has had enough time to play through.

所以不是

audio.onload = isAppLoaded;

尝试

audio.oncanplaythrough = isAppLoaded;

或者更好的..;）

Or better yet.. ;)

audio.addEventListener('canplaythrough', isAppLoaded, false);
