<audio src= "Music/bg.mp3" AutoPlay loop controls> your browser is not yet supported Oh </audio>

        //音频，写法二

<audio controls= "Controls" >         <source src= "Music/bg.ogg" type= "Audio/ogg" ></source>        < SOURCE src= "Music/bg.mp3" type= "Audio/mpeg" ></source>        //Priority play Music Bg.ogg, not supported in play Bg.mp3</ Audio>

 //JS绑定自动播放（操作window时，播放音乐）

  function () {        music.play ();    })

 //下兼容处理

function () {        music.play ();     false);
