现在网络上绝大部分地址选择器都是3级地址选择而且很成熟，4级、5级地址选择基本都是PC端的demo比较多，另外就是绝大部分都是本地地址库，把所有层级地址塞到一起然后来用，使用限制比较大！我理想的地址选择器是什么样呢？
- 首先是要用于移动端网页选择，而且不想做成每个层级选择单独点选
- 考虑到扩展性及数据交互，最好能支持从接口动态获取每个层级的内容
- 支持部分层级结束，也就是说某些选择路径可能到第N个层级就没有下级了（此时还没选到最大层级）
- 最好实现不要太复杂，js实现或可便捷引用实现。
抱着上面的需求，零零散散花费了我6天的时间，可以说是翻遍的百度、bing、掘金、github，最终找到了一个看起来符合需求的项目：https://github.com/huangjieqiu/ajax-picker 最终下载下来后发现距离我想要的效果还有一定差距，后面也没找到其他更贴近的地址选择器源码了，就打算对其进行修改优化（因为项目本身没有什么注释，我又不是专门做前端的，消化了不少时间）。
过程不多说下面直接贴源码就3个文件（后面有时间我再传github一份：https://github.com/joolan/ajax-picker-html）：
