javascript - phonegap geocoder.geocode 从结果中获取门牌号

Question

我有这个地理编码器代码:

function codeLatLng(lat, lng) {
 geocoder = new google.maps.Geocoder();
    var latlng = new google.maps.LatLng(lat, lng);
    geocoder.geocode({'latLng': latlng}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
      console.log(results)
        if (results[1]) {
         //formatted address
         alert(results[0].formatted_address)//this is a string of all location 

        } else {
          alert("No results found");
        }
      } else {
        alert("Geocoder failed due to: " + status);
      }
    });
  }

我想将街道和门牌号保存在不同的变量中，我该怎么做？

根据the documentation ，您可以从地理编码 API 响应中获取 address_components，而不是获取 formatted_address，然后获取例如 street_number:

"address_components" : [
    {
       "long_name" : "1600",
       "short_name" : "1600",
       "types" : [ "street_number" ]
    },
    ...
]

您可以通过迭代 address_components 来获取所需的组件(在本例中我正在检索 street_number):

for (var i = 0; i < results[0].address_components.length; i++) {
    var address_components = results[0].address_components[i];
    if (address_components.types[0] == 'street_number') {
        console.log(address_components.long_name);
    }
}
