如何从谷歌地图的自动完成API获取邮政编码

Question

所以我的问题是结果随即吐出:

1980 Mission Street,旧金山,加利福尼亚州,美国

...但我需要它给我邮政编码,因为当我把它放回谷歌的地理编码器时,由于某种原因它没有注册位置.

//这是我只有自动完成输入字段的代码

var input = document.getElementById('id_address');
var options = {
  types: ['address'],
  componentRestrictions: {country:'us'}
};
autocomplete = new google.maps.places.Autocomplete(input, options);

//这就是我使用地理编码器的方式

window.onload = function initMap() {
            console.log("{{ task.address }}");
            console.log("{{ location }}");
            var address = "{{ location }}";

            geocoder = new google.maps.Geocoder();

            geocoder.geocode({ 'address': address }, function(results, status) {
                <!-- console.log(address); -->
              if (status == google.maps.GeocoderStatus.OK) {
                var map = new google.maps.Map(document.getElementById('map'), {
                    center: results[0].geometry.location,
                    zoom: 12,
                  });
                var marker = new google.maps.Marker({
                    map: map,
                    position: results[0].geometry.location,
                  });
              }


            });

        }

我有一个有效的解决方案,但用户必须分别输入每个地址.我正在尝试更改它,以便他们可以只填写一个输入字段然后我可以将该地址吐入gecoder.geocode().

任何建议都非常感谢.谢谢.

包含一个数组返回的结果,其中一个条目的类型为'postal_code',对于您的样本地址("1980 Mission Street,San Francisco,CA,United States"),包含94103.autocompleteaddress_components

注意:一个城市,县或州通常有一个以上的邮政编码,获得一个唯一的邮政编码的唯一方法是反转地理编码返回的坐标,这是否足够取决于使用.

function initialize() {
  var input = document.getElementById('id_address');
  var options = {
    types: ['address'],
    componentRestrictions: {
      country: 'us'
    }
  };
  autocomplete = new google.maps.places.Autocomplete(input, options);
  google.maps.event.addListener(autocomplete, 'place_changed', function() {
    var place = autocomplete.getPlace();
    for (var i = 0; i < place.address_components.length; i++) {
      for (var j = 0; j < place.address_components[i].types.length; j++) {
        if (place.address_components[i].types[j] == "postal_code") {
          document.getElementById('postal_code').innerHTML = place.address_components[i].long_name;

        }
      }
    }
  })
}
google.maps.event.addDomListener(window, "load", initialize);
