200分奉上,CSDN挂了半个月了还没解决,导航菜单问题,高手帮帮忙啊>>>>>>>>>>>>>>>>>>>>>

http://community.csdn.net/Expert/topic/5313/5313437.xml?temp=.4201166这里还有100分~~~A:link{
color:#215DC6;
text-decoration:none;

A:active:{
color:#428EFF;
text-decoration:none;
background-image:url("../images/over0001.bmp");
}
A:visited{
color:#215DC6;
text-decoration:none;
}
A:hover{
color:#428EFF;
}
以上是左侧导航菜单在CSS中的设置，（over0001.bmp为一突显颜色图片）点击后，over0001会显示上去，但是点击右面面板后，突显就没有了，
请问如何解决阿？
要用代码的话要怎么加呢?

A:active:{
background-image:url("../images/over0001.bmp");
}这是激活时，显示IMAGE，当然焦点离开后就没了。
用JS实现起来比较容易，用CSS在下就不知道了。（如果有CSS高手，也应该能解决）

搂主你要的for(i=0;i<document.all.tags('td').length;i++)
if (document.all.tags('td')[i].className.indexOf('headtd') == 0)
document.all.tags('td')[i].className = 'headtd1';
obj2.className = 'headtd2';
<style type='text/css'>
.headtd1 {  background: #799AE1; border: 2px outset; border-color: #00BBFF #0077FF #0077FF #00BBFF; cursor: hand; font-size: 9pt}
.headtd2 {  background: #20C1FF; border: 2px outset; border-color: #60D3FF #0077FF #0077FF #60D3FF; cursor: hand; font-size: 9pt}
.bodytd  {  background: #D6DFF7; border: 1px; border-color: #B0D8FF #0077FF #0077FF #B0D8FF; font-size: 9pt}
</style>主要是这几个地方。
在ASP.NET 2.0自带Menu上用纯CSS做不到的，一定要加JavaScript来确定当前点击的菜单项，并且找出它的所有祖先菜单项并改变className。然后还要修改当Menu关闭时的代码，也就是将这些className改回去。如果你自己的JavaScript功底过关，你可以自行研究Menu自带的那个Menu.js，然后看看如何改进。我建议不要用原本那个Menu的输出样式，因为它是<table />排版，而用ASP.NET CSS Friendly ControlAdapter（你用Google搜索一下就能找到这东西），经它修正后的Menu输出时<ul />，这样其JavaScript也就变得简单了。
