推荐答案

有一个名为GeoNames的组，它提供可下载的数据库和免费的Web服务来获取此类数据.例如，搜索

There's a group called GeoNames that offers both downloadable databases and free webservices to obtain this type of data. For example, the search

http://ws.geonames.org/searchJSON?name_startsWith=Chic&country=US

将返回一堆包含IL，Chicago的JSON(JSON属性包括"name":"Chicago"和"adminCode1":"IL").

will return a bunch of JSON that includes Chicago, IL (JSON properties include, among others, "name":"Chicago" and "adminCode1":"IL").

碰巧的是，jQuery UI伙计们将此数据源用于自动完成演示. (感谢NickT的链接).
