JEECMS 导航栏实现二级菜单功能

1.首先登录 

http://localhost:8080/jeeadmin/jeecms/index.do

JEECMS的管理后台

配置-->模板   修改 index目录下的index.html 与 include目录下的navi.html

原理:

为生成的ul 添加鼠标划入划出效果便可

index.html关键代码

<script type="text/javascript">
$(function() {
        //当鼠标指针穿过元素
        $(".sub").mouseenter(function(){
                //alert("...");
                varthis = $(this);
                //alert("varthis:"+varthis);
                //console.log("%o",varthis);
                varthis.find('ul').slideDown();
		//var tar = varthis.find('ul');
                //console.log("%o",tar);
        });
        //当鼠标指针离开元素时
        $(".sub").mouseleave(function(){
                //alert("...");
                varthis = $(this);
                //alert("varthis:"+varthis);
                //console.log("%o",varthis);
                varthis.find('ul').slideUp();
		//var tar = varthis.find('ul');
                //console.log("%o",tar);
        });
        //事件必须添加在该行以前
	Cms.siteFlow("${base}", location.href, document.referrer);
	$.cookie("_site_id_cookie","${site.id!}",{path: '${base}' });
});
</script>

navi.html代码

<div id="menu">
	<ul id="nav"> 
		[@cms_channel_list] 
		[#list tag_list as c]
		 [@cms_channel_list parentId=c.id]
