本着服务为人民的远大理想，最近写了个jquery模拟select效果的小东东，挺好用，分享下。
可以直接在我上传的资源里下载压缩包，下载地址：jquery模拟实现仿select效果。
首先，上html页面代码
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>js模拟select</title>
<link rel="stylesheet" type="text/css" href="style.css" target="_blank" rel="external nofollow" >
</head>
<body>
<div class="container">
<div class="select-box select-city">
<div class="select-header"> 省份 </div>
<ul class="select-content">
<li>北京</li>
<li>河北省</li>
<li>山东省</li>
</ul>
</div>
<div class="select-box select-city">
<div class="select-header"> 城市 </div>
<ul class="select-content">
<li>北京</li>
</ul>
</div>
<div class="select-box select-city">
<div class="select-header"> 区/县 </div>
<ul class="select-content">
<li>海淀区</li>
<li>朝阳区</li>
<li>东城区</li>
</ul>
</div>
</div>
</body>
<script src="js/jquery.min.js"></script>
<script src="js/select.js"></script>
</html>
然后，上css代码
@charset "utf-8";
body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,form,fieldset,input,textarea,p,blockquote,th,td,p{margin:0;padding:0; font-family:"微软雅黑", Microsoft Yahei, Arial, Helvetica, sans-serif;}
ol,ul{list-style:none;}
.container{ padding-top:100px; margin-left:100px;}
/**
* 模拟select
**/
.select-box { position: relative; float: left; margin-right: 8px; }
.select-city .select-header { width: 88px; height: 36px; border: 1px solid #c1c1c1; padding-right: 26px; background: url(img/arrow.png) no-repeat #f9f9f9; background-position: 95px 15px; line-height: 36px; text-indent: 14px; font-size: 16px; color: #a9a9a9; cursor: pointer; overflow: hidden; }
.select-city .select-arrow { background-position: 95px -9px; }
.select-city .select-content { border-left: 1px solid #c1c1c1; border-right: 1px solid #c1c1c1; position: absolute; top: 38px; left: 0; z-index: 99; display: none; background-color: #f9f9f9; }
.select-city .select-content li { width: 114px; height: 36px; margin: 0; border-bottom: 1px solid #c1c1c1; line-height: 36px; text-indent: 14px; background-color: #f9f9f9; font-size: 16px; color: #a9a9a9; cursor: pointer; }
.select-bank .select-header { width: 272px; height: 36px; border: 1px solid #c1c1c1; padding-right: 26px; background: url(img/arrow.png) no-repeat #f9f9f9; background-position: 279px 15px; line-height: 36px; text-indent: 14px; font-size: 16px; color: #a9a9a9; cursor: pointer; overflow: hidden; }
.select-bank .select-arrow { background-position: 279px -9px; }
.select-bank .select-content { border-left: 1px solid #c1c1c1; border-right: 1px solid #c1c1c1; position: absolute; top: 38px; left: 0; z-index: 99; display: none; background-color: #f9f9f9; }
.select-bank .select-content li { width: 298px; height: 36px; margin: 0; border-bottom: 1px solid #c1c1c1; line-height: 36px; text-indent: 14px; background-color: #f9f9f9; font-size: 16px; color: #a9a9a9; cursor: pointer; }
最后，上js代码：
$(function(){
/**
* 模拟select
**/
$(".select-header").click(function(){
$(this).parent().siblings(".select-box").find(".select-content").slideUp("fast");
if($(this).siblings(".select-content").is(":hidden")){
$(this).addClass("select-arrow");
$(this).siblings(".select-content").slideDown("fast");
var evt = new Object;
if ( typeof(window.event) == "undefined" ){//如果是火狐浏览器
evt = arguments.callee.caller.arguments[0];
}else{
evt = event || window.event;
}
evt.cancelBubble = true;
}else{
$(this).removeClass("select-arrow");
$(this).siblings(".select-content").slideUp("fast");
//去除事件冒泡
var evt = new Object;
if ( typeof(window.event) == "undefined" ){//如果是火狐浏览器
evt = arguments.callee.caller.arguments[0];
}else{
evt = event || window.event;
}
evt.cancelBubble = true;
}
});
$(document).click(function(){
$(".select-header").removeClass("select-arrow");
$(".select-content").slideUp("fast");
});
$(".select-content li").on("click",function(){
$(this).parent().siblings(".select-header").removeClass("select-arrow");
$(this).parent().siblings(".select-header").text($(this).text()).end().slideUp("fast");
});
$(".select-content li").hover(function(){
$(this).css("background-color","#cfcfcf");
},function(){
$(this).css("background-color","#fff");
});
});
效果如下：
