这是JS
[javascript]
<script src="Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
<script type="text/javascript">
window.onload=function()
{
     setMenuBackground();
}

</script>
<script type="text/javascript">

function setMenuBackground()
{
     var url = document.URL;//取得当前页的URL

     if(/index/.test(url.toLowerCase()))   //正则查找在url地址中是否有当前页
     {
         $("#a_menu").addClass("dh_nav_y");
    }else if(/header/.test(url.toLowerCase()))
    {
         $("#b_menu").addClass("dh_nav_y");
    }else if(/music/.test(url.toLowerCase()))
    {
         $("#c_menu").addClass("dh_nav_y");
    }else if(/keji/.test(url.toLowerCase()))
    {
         $("#d_menu").addClass("dh_nav_y");
    }else if(/guonei/.test(url.toLowerCase()))
    {
         $("#e_menu").addClass("dh_nav_y");
    }else if(/yule/.test(url.toLowerCase()))
    {
         $("#f_menu").addClass("dh_nav_y");
    }
}
</script>
这是HTML
[html]
<div class="dh_nav_l">
        <ul>
            <li id="a_menu" ><a href="index.html">首页</a></li>
            <li id="b_menu" ><a href="header.html">儿童</a></li>
            <li id="c_menu" ><a href="music.html">音乐MV</a></li>
            <li id="d_menu" ><a href="keji.html">国内</a></li>
            <li id="e_menu" ><a href="guonei.html">娱乐</a></li>
            <li id="f_menu" ><a href="yule.html">科技</a></li>
        </ul>
    </div>
