刚刚做了一个菜单导航变亮的效果，共享一下吧！

ASXC代码：

<script>

    $(function() {

    //菜单变亮

        $(".menubanner>ul>li").find("a[href$='" + location.href.split(window.location.host)[1] + "']")

                              .closest("li").addClass("current");

if (location.href.split(window.location.host)[1] == ""

|| location.href.split(window.location.host)[1] == "/")

            $(".menubanner>ul").find("li:first").addClass("current");

    });

</script>

<div class="menubannerLeft">

</div>

<div class="menubanner">

    <%

        Entity.Commons.VPredication vp = new Entity.Commons.VPredication();

        Service.IMenusService iMenusService = new Service.MenusService();

        List<Entity.OA.Menu> menu = iMenusService.GetShareMenuList();

    %>

    <ul>

        <%foreach (var i in menu)

          {

        %>

        <li><a href="<%=i.URL %>">

            <%=i.MenuName%></a></li>

        <%}

        %>

    </ul>

</div>

<div class="menubannerRight">

</div>

<div style="clear: both">

</div>

CSS代码：
