动态改变frame里的src，显示不同的内容

Question

大家好，我有一个html页面，他是由2个frame组成的，他们组成一个大屏（2个显示器合并那么大）现在我需要实现的是，每隔10秒左边的frame的内容动态变化，也就是src里的htm页面动态变化，比如说我有popScreenLeft.htm，popScreenLeft1.htm，popScreenLeft3.htm  3个页面，让他们每轮流显示，每个显示10秒。请问能否实现。谢谢！<frameset rows="*" cols="1215,*" framespacing="0" frameborder="yes" border="0">
<frame src="popScreenLeft.htm" name="leftFrame" scrolling="NO" >
  <frame src="popScreenRight_new.htm" name="mainFrame"　scrolling="NO">
</frameset>

<frameset rows="*" cols="1215,*" framespacing="0" frameborder="yes" border="0"> 
<frame src="popScreenLeft.htm" name="leftFrame" scrolling="NO" > 
  <frame src="popScreenRight_new.htm" name="mainFrame"　scrolling="NO"> 
</frameset>
<script>
var locations=["popScreenLeft.htm"，"popScreenLeft1.htm"，"popScreenLeft3.htm"];
var index=0;
var TIMER;
function changeperten(){
   leftFrame.location.herf=locations[index++];
   TIMER=setTimeout(changeperten,10000);
}
window.onload=function(){
   TIMER=setTimeout(changeperten,10000);
}
</script>

 leftFrame.location.herf=locations[index++%3] 改一下

<script language="javascript">
var n = 0;
var urls = ['popScreenLeft.htm','popScreenLeft1.htm','popScreenLeft3.htm'];
function doit(){
  leftFrame.location.href = urls[n] + "?" + escape(new Date());
  n++;
  if(n==3) n=0;
}
window.onload=function(){
setInterval("doit()", 1000)
}
</script>
<frameset rows="*" cols="1215,*" framespacing="0" frameborder="yes" border="0"> 
<frame src="popScreenLeft.htm" name="leftFrame" scrolling="NO" > 
  <frame src="popScreenRight_new.htm" name="mainFrame"　scrolling="NO">
