javascript - 在自动完成选择时解析谷歌地图中的 address_components

Question

我有以下代码来解析 country 选择“自动完成”列表时:

$('#spot_address').autocomplete({
  // This bit uses the geocoder to fetch address values
  source: function(request, response) {
    geocoder.geocode( {'address': request.term }, function(results, status) {
      // Get address_components
      for (var i = 0; i < results[0].address_components.length; i++)
      {
        var addr = results[0].address_components[i];
        var getCountry;
        if (addr.types[0] == 'country') 
          getCountry = addr.long_name;
      }
      response($.map(results, function(item) {
        return {
          label: item.formatted_address,
          value: item.formatted_address,
          latitude: item.geometry.location.lat(),
          longitude: item.geometry.location.lng(),
          country: getCountry
        }
      }));
    })
  },

  // This bit is executed upon selection of an address
  select: function(event, ui) {
    // Get values
    $('#spot_country').val(ui.item.country);
    $('#spot_lat').val(ui.item.latitude);
    $('#spot_lng').val(ui.item.longitude);
    var location = new google.maps.LatLng(ui.item.latitude, ui.item.longitude);
    marker.setPosition(location);
    map.setCenter(location);
  },

  // Changes the current marker when autocomplete dropdown list is focused
  focus: function(event, ui) {
    var location = new google.maps.LatLng(ui.item.latitude, ui.item.longitude);
    marker.setPosition(location);
    map.setCenter(location);
  }
});

但是，上面的代码不起作用，在解析国家时，无论如何只解析自动完成的第一个结果，这对数组results[0]有意义因为它只获取第一个结果。

我试图将它移动到select函数中，但是select中的ui只包含formatted_address，longitude 和 latitude，但不是 address_components。

选择“自动完成列表”项目时，我必须怎么做？

非常感谢。

一般解决方案:

var address_components = results[0].address_components;
var components={}; 
jQuery.each(address_components, function(k,v1) {jQuery.each(v1.types, function(k2, v2){components[v2]=v1.long_name});});

现在你的组件看起来像这样:

street_number: "1100", 
route: "E Hector St", 
locality: "Conshohocken", 
political: "United States", 
administrative_area_level_3: "Whitemarsh"…
administrative_area_level_1: "Pennsylvania"
administrative_area_level_2: "Montgomery"
administrative_area_level_3: "Whitemarsh"
country: "United States"
locality: "Conshohocken"
political: "United States"
postal_code: "19428"
route: "E Hector St"
street_number: "1100"

你可以这样查询:

components.country
