如何也同时切换背景音乐？
<script>
var a=new Array("images/04.jpg","images/05.jpg","images/06.jpg");
var b=new Array("music/01.mp3","music/02.mp3","music/03.mp3");
var i=0;
var h=0;
var n=0;
var timer;
function f()
{ i++;
if(i>2){
i=0;
}
document.getElementById("imageId").src = a[i];
n=0;
time();
}
function music(){
h++;
if(h>2)
b=0;
document.getElementById("musicId").src=b[h];
}
function time(){
imageId.style.opacity=n;
n=n+0.1;
timer=setTimeout("time()",500);
if(n>=1)
clearTimeout(timer);
}
</script>
<style>
.s1{ font-family:STCaiyun;font-size:60px;background:linear-gradient(30deg,#ff00ff,#00ff00);width:100%;
height:14.5%;font-weight:bold;text-align:center; }
#s2{ margin-top:0.5%; }
</style>
<div class="s1">
<br>Music Wall
</div>
<div id="s2" >
<img src="images/04.jpg" width="1889" height="727" onclick="f()" onload="time()" onclick="music()" id="imageId" >
<embed src="music/01.mp3" autostart=true loop=false hidden=true id="musicId" >
</div>
