现在我能够实现当前页面的iframe内容的切换JS代码如下：
<script language="javascript" type="text/javascript">//页面跳转
function goURL(urla,urlb)
{
var urla
var urlb
main.location.href=urla;
side.location.href=urlb;
document.getElementById('main').width="671px";
document.getElementById("side").width='281px';
}
</script>导航按钮代码：
<a href="#" onClick="javascript:goURL('ind_left.html','ind_right.html');">我的主页</a>
<a href="#" onClick="javascript:goURL('nav_cwgl.html','right.html');">查询服务</a>iframe代码：
<iframe id="main" src="ind_left.html" frameborder="0" scrolling="No" onload="this.height=this.contentWindow.document.body.scrollHeight" width="671"></iframe>
<iframe id="side" src="ind_right.html" frameborder="0" scrolling="No" onload="this.height=this.contentWindow.document.body.scrollHeight" width="281"></iframe>现在客户要求，需要在左侧iframe被嵌入的页面中，在嵌入左右两个iframe；
也就是说父级页面有两个iframe,被嵌套页也有2个iframe。
这样如何才能使点击导航后，子页面的2个iframe也能够进行内容切换调用？

}

<iframe id="ind_right_2" src="ind_right_2.html" frameborder="0" scrolling="No" width="371"></iframe>
哎呀呀，貌似不行啊，是这样弄么？

左侧iframe页：<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

</tr>
</table>
</body>
</html>
document.getElementById("main").contentWindow.document.getElementById("left.html").contentWindow.document.location.href=urlc;改为
document.getElementById("main").contentWindow.document.getElementById("ind_left_1").contentWindow.document.location.href=urlc;
下面我想让id="ind_right_2"也要随之切换，将您的代码修改了下，如下：
<script language="javascript" type="text/javascript">//页面跳转
function goURL(urla,urlb,urlc,urld)
{
var urla
var urlb
side.location.href=urlb;
document.getElementById("side").width='200px';
alert(urlc,urld);
document.getElementById("main").contentWindow.document.getElementById("liframe").contentWindow.document.location.href=urlc;
document.getElementById("main").contentWindow.document.getElementById("riframe").contentWindow.document.location.href=urld;
}
</script>
为什么，当我点击“我的主页2"之后，ind_right_2对应的iframe会显示“此程序无法显示网页”呢？
