使用google api从位置提取省份 [英] extract province from location using google api

问题描述

我正在尝试使用google map api从某个位置提取一些额外信息。我看看它是可能的，但我不明白我在哪里放置bounds参数。这是我的要求：

I'm trying to extract some extra information from a location using google map api. I take a look and it's possible but I don't understand well where I've to put the bounds parameter. This is my request:

var address = document.getElementById("address").value;
    geocoder.geocode( { 'address': address}, function(results, status) {
    if (status == google.maps.GeocoderStatus.OK) {
        alert(results[0].formatted_address);    
    } else {
        alert("Geocode was not successful for the following reason: " + status);
    }
});

我想在地址之后添加绑定：地址但不清楚如何。我试过了，但它不起作用：

I suppose to add the bound after 'address':address but not clear how. I tryied with that but it doesn't works:

geocoder.geocode( { 'address': address, "types":["sublocality","political"]}, function(results, status) {

我不喜欢知道是否熟悉意大利省但我需要这样的东西：

I don't know if have familiar with Italian province but I need something like that:

请求：Venezia

回应：VE或威尼斯

Request: Venezia
Response: VE or Venezia

请求：Murano

回复：VE或Venezia

Request: Murano
Response: VE or Venezia

----改进：

使用 http://maps.googleapis.com/maps/api/geocode/json?address=murano&sensor=false 我可以获得：

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "Murano",
               "short_name" : "Murano",
               "types" : [ "natural_feature" ]
            },
            {
               "long_name" : "Venezia",
               "short_name" : "Venezia",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Venezia",
               "short_name" : "VE",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "Veneto",
               "short_name" : "Veneto",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {
               "long_name" : "Italia",
               "short_name" : "IT",
               "types" : [ "country", "political" ]
            },
            {
               "long_name" : "30141",
               "short_name" : "30141",
               "types" : [ "postal_code" ]
            }
         ],

尝试使用alert打印（results [0] .address_components）;它没有给我任何东西，我怎么能提取这个：

Trying to print using alert(results[0].address_components); it doesn't show me anything, how can I extract this:

           "long_name" : "Venezia",
           "short_name" : "VE",
           "types" : [ "administrative_area_level_2", "political" ]

谢谢，
Andrea

推荐答案

除了<$ c $迭代，我没有看到任何其他解决方案c> address_components 并将第一个数据与 short_name 匹配，其中包含2个字母。

I do not see any other solution than iterate by address_components and match first data with short_name that contains 2 letters.

var len = results[0].address_components.length;
var data;
for ( var i = 0; i < len; i++ ) {
    if ( results[0].address_components[i].short_name.length == 2 ) {
        data = results[0].address_components[i];
        break;
    }
}
