看到51job的地区选择控件，一直都想自己做一个，一开始使用ajax.net提供的控件搭建了一个可以无限分级的地区选择控件，而且是动态从数据库中获取上级地址信息再读取地址列表，但是发现速度实在太慢，最近发现网上有人用纯js写了个，便贴上来以供参考，希望以后抽时间把它改成动态获取地址信息且无限分级选择的控件！点此查看效果

添加城市方法：
添加组：找到id 是 "selectSub"中select标签下，添加option标签 value属性递增，找到 id 是 "selectSub",按照原有格式添加div,其id属性递增
添加二级傅选矿选项
复制 id 是 "selectSub" 下任意input标签，粘贴在需要添加的位置。
