Question

我正在使用Google Maps API指南进行自动填充：

https://developers.google.com/maps/documentation/javascript/examples/places-autocomplete-addressform

但似乎无法发现意大利各省。

例如：输入意大利语地址＆＃34; Caronno Pertusella，VA，Italia＆＃34;，我无法检测到＆＃34; VA＆＃34;。

我尝试添加和更改参数：https://developers.google.com/maps/documentation/javascript/geocoding

但我找不到省参数。

Answer 1

这本来可以更容易。我想你正在寻找administrative_area_level_2。因为这个级别因国家/地区而异，所以您需要测试，哪个级别符合您的需求。附上了administrative_area_level_2（＆＃39; short_name＆＃39;）的示例。你可以玩一点，Reinhard

Answer 2

如果您搜索：＆＃34; Caronno Pertusella VA，Italia＆＃34; =在VA之前没有逗号，你会得到它。还有＃34; Caronno Pertusella VA，它＆＃34;将工作。在城市逗号之后，自动完成等待国家或国家/地区代码。

顺便说一句，为什么你不只是选择其中一个自动完成提案？如果你输入＆＃34; Caronno＆＃34;你得到了建议：＆＃34; Caronno Pertusella Varese，Italia＆＃34;
