帝国CMS导航条js高亮当前列，用JS方法修改

<script type="text/javascript" language="javascript">
var nav = document.getElementById("navi3");
var links = nav.getElementsByTagName("li");
var lilen = nav.getElementsByTagName("a"); //判断地址
var currenturl = document.location.href;
var last = 0;
for (var i=0;i<links.length;i++)
{
   var linkurl =  lilen[i].getAttribute("href");
     if(currenturl.indexOf(linkurl)!=-1)
        {
         last = i;
        }
}
         links[last].className = "current-menu-item";  //高亮代码样式
</script>
