问题描述
我知道如何在Javascript中检查HTML5音频播放是否可用.但是我该如何具体检查MP3音频播放是否可用，因为IE9和Chrome支持它，而Firefox和Opera没有.
I know how to check in Javascript if HTML5 audio playback is available. But how do I specifically check if MP3 audio playback is available, as IE9 and Chrome support it, while Firefox and Opera do not.
推荐答案
您可以检查User-Agent并查看正在使用的浏览器，也可以测试对Javascript的支持.
You could either check the User-Agent and see what browser is being used or you could test support with Javascript.
var a = document.createElement('audio');
return !!(a.canPlayType && a.canPlayType('audio/mpeg;').replace(/no/, ''));
我从此页面中获得了上述代码.
I got the above code from this page.
返回!!(a.canPlayType)更好，因为(某些最新版本的)Firefox不支持mp3，而a.canPlayType('audio/mpeg;')将为假
return !!(a.canPlayType) is better because (some recent versions of)Firefox not supports mp3 and a.canPlayType('audio/mpeg;') will be false
