本文實例講述了js實現仿阿里巴巴城市選擇框效果。分享給大家供大家參考。具體分析如下：

這并不是一個城市選擇插件，在這里介紹只是為了mark一下二級聯動的方法，此效果適用于有二級子菜單的效果，如導航欄、城市選擇、類別選擇等等。

樣式效果是基于阿里的樣式，懶得做其他調整，在area.css中僅僅是為了修改瀏覽器兼容性略做了一點調整。

城市數據是通過js構造，當然也可以通過后端取得數據，不過感覺沒必要。

<!doctype html> <html> <head> <meta charset="utf-8"> <script type="text/javascript" src="http://code.jquery.com/jquery-1.10.1.js"></script> <script type="text/javascript" src="area.js"></script> <link rel="stylesheet" href="area.css" type="text/css" /> <style type="text/css"> /*reset css*/ *{margin:0;padding:0;} a{text-decoration: none;} /*appearence css*/ .area{height: 32px;line-height: 32px;font-size: 12px;background-color: #f8f8f8;border: 1px solid #ccc;border-top: 2px solid #ff8033;} .area b{color: #333;margin: 0 13px 0 10px;float: left;} .def_box{display: block;float: left;background-color: #fff;padding: 0 18px 0 10px;border: 1px solid #ccc;height: 20px;margin-top: 5px;line-height: 20px;cursor: pointer;position: relative;z-index: 300;}</style> </head> <body>   <div class="area">     <b>地區：</b>     <span class="def_box">選擇地區</span>   </div> </body> </html>

area.css代碼如下：
