动态改变frame里的src，显示不同的内容
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>

改一下10秒
HTML code
<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()", 10000)}</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"> </frameset>
