给你的网页添加一个随机的BGM

大晚上的，突然想到，我这么喜欢听歌的人，博客里怎么能少了BGM呢，说干就干。

首先，给博客侧边栏加一个空div：<div id="music"></div>

然后就是js了，下面奉上js代码：

//500英里
var m1="http://win.web.rh03.sycdn.kuwo.cn/a350d16bcc9f510464e06e582c7a3a3e/5ab141af/resource/a1/20/25/1132448623.aac";
//我爱你

//see you again

var x=Math.round(Math.random()*9);
console.log(x);
if (x==0) x=m1
else if (x==1) x=m2
else if (x==2) x=m3
else if (x==3) x=m4
else if (x==4) x=m5
else if (x==5) x=m6
else if (x==6) x=m7
else if (x==7) x=m8
else if (x==8) x=m9
else  x=m10
var obj = document.getElementById("music");
obj.innerHTML='<audio src='+'"'+x+'"'+' '+'height="0"'+'autoplay="true"'+'loop="true"'+'>'+'</audio>';

如此，就实现了每次刷新页面的时候，随机播放上面10首歌里面的任意一首。

So easy!
