急问，求这样的效果代码:二级联动菜单并点击自动跳出页面。

静态的话你需要有街道地图和下属村的资料，用 javascript 的全局变量：数组或对象存起来。

然后再select绑定一个onchange事件，调用一个function去改变后面一个select的内容，同时读取相应的图片

例子：

var list = [

{ name:'街道1', list: [ ‘下属村1|图片路径’, ‘下属村2|图片路径’, ‘下属村3|图片路径’ ] },

{ name:'街道2', list: [ ‘下属村1|图片路径’, ‘下属村2|图片路径’, ‘下属村3|图片路径’ ] },

]

css二级菜单样式如何设置

代码粘贴的太复杂；

先给你分析一下原理：二级菜单没有在没有hover属性的情况下是隐藏的所以需要display：none，当鼠标hover的时候二级菜单才会列出来，这是纯css可以实现的；

知道上面的原理之后，下面比较容易实现具体看例子：

HTML代码：

ul

lia href=""一级菜单/a/li

lia href=""一级菜单/a

ul class="drop-ul"

li a href=""二级菜单/a/li

/ul

/li

/ul

CSS代码：

ul li ul.drop-ul{ display: none;position:relative }/*正常情况下隐藏*/

ul li:hover ul.drop-ul li{display: block;} /*当鼠标放上去二级菜单li 显示出来*/

/*这个时候你会发现二级菜单显示的位置可能不对可以使用position属性*/

ul li:hover ul.drop-ul li{position:absolute;}

/*通过top right left 调整位置，根据实际情况调整背景颜色，字体颜色等，细节东西*/

此时可能会发现会二级菜单出现有那么一点点的生硬；没关系配合jquery实现缓慢展现效果

$(document).ready(function() {

if($(window).width()  768) {

$('ul li').hover(

function() {

$('ul', this).stop().slideDown(200);

  },

function() {

     $('ul', this).stop().slideUp(200);

   }

);

}

});

注意不知道jquery的新手使用记住先加载Jquery.min.js文件，放在此段js前面；

如何用css制作横排二级下拉菜单

css制作横排二级下拉菜单，代码如下：

body

ul id="FM"

lia href="#"一级栏目/a

ul

lia href="#"二级菜单/a/li

lia href="#"二级菜单/a/li

lia href="#"二级菜单/a/li

/ul

/li

lia href="#"一级栏目/a

ul

lia href="#"二级菜单/a/li

lia href="#"二级菜单/a/li

lia href="#"二级菜单/a/li

/ul

/li

lia href="#"一级栏目/a

ul

lia href="#"二级菜单/a/li

lia href="#"二级菜单/a/li

lia href="#"二级菜单/a/li

/ul

/li

/ul

/body

CSS样式设置代码，如下；

style type="text/css"

ul#FM li {

float:left;

width:160px;

list-style:none;

}

ul#FM li ul {

display:none;

margin:0;

padding:0;

}

ul#FM li:hover ul{

display:block;

}

ul#FM li a{

display:block;

border:1px solid red;

text-decoration:none;

color:#000;

}

ul#FM li li a {

display:block;

font-size:12px;

border:1px solid green;

padding:3px;

text-decoration:none;

width:152px;

color:#CC3399;

}

ul#FMli li a {

width:auto;

}

/style

所做出来的效果，鼠标放上去时，如图；

zblog php版怎么制作下拉菜单归档功能

纯css实现的，所以任性的不需要js部分了，但是要详细说明下，上面的html代码中的“{module:catalog}”调用出来的是网站分类，当某个分类下有子分类（二级分类）时自动出现下拉导航，很方便。

可是这样做有个缺陷，就是网站的单页面如留言本、关于我们啊这些就不能出现在导航栏上面了，因为调用的是网站分类而不是导航栏，所以对这个有需求的同学可以把html代码部分改成这样：
