function checkAudio(){
var myAudio = document.createElement('audio');
if (myAudio.canPlayType) {
if ( "" != myAudio.canPlayType('audio/mpeg')) {
document.write("您的浏览器支持mp3编码。<br>");
}
if ( "" != myAudio.canPlayType('audio/ogg; codecs="vorbis"')){
document.write("您的浏览器支持oog编码。<br>");
}
if ( "" != myAudio.canPlayType('audio/mp4; codecs="mp4a.40.5"')) { document.write("您的浏览器支持aac编码。");
}
}
else {
document.write("您的浏览器不支持要检测的音频格式。");
}
}
window.onload=function() {
checkAudio();
}
</script>
</head>
<body>
