get city from geocoder results?

Question

Having problems getting the different arrays content from geocoder results.

item.formatted_address works but not item.address_components.locality?

Answer 1

I think it is a real pain that google doesn't provide some sort of functionality to get these. Anyhow I think the best way of finding the right object is:

geocoder.geocode({'address': request.term }, function(results, status){

   response($.map(results, function(item){

      var city = $.grep(item.address_components, function(x){
         return $.inArray('locality', x.types) != -1;
      })[0].short_name;

      alert(city);
   }            
}); 

Answer 2

This worked for me:

const localityObject = body.results[0].address_components.filter((obj) => {
  return obj.types.includes('locality');
})[0];
const city = localityObject.long_name;

or in one go:

const city = body.results[0].address_components.filter((obj) => {
  return obj.types.includes('locality');
)[0].long_name;

I'm doing this in Node, so this is okay. If you need to support IE you need to use a polyfill for Array.prototype.includes or find another way of doing it.

I am assuming you want to get the city and the state / province:

var map_center = map.getCenter();
reverseGeocode(map_center);


function reverseGeocode(latlng){
  geocoder.geocode({'latLng': latlng}, function(results, status) {
      if (status == google.maps.GeocoderStatus.OK) {
            var level_1;
            var level_2;
            for (var x = 0, length_1 = results.length; x < length_1; x++){
              for (var y = 0, length_2 = results[x].address_components.length; y < length_2; y++){
                  var type = results[x].address_components[y].types[0];
                    if ( type === "administrative_area_level_1") {
                      level_1 = results[x].address_components[y].long_name;
                      if (level_2) break;
                    } else if (type === "locality"){
                      level_2 = results[x].address_components[y].long_name;
                      if (level_1) break;
                    }
                }
            }
            updateAddress(level_2, level_1);
       } 
  });
}

function updateAddress(city, prov){
   // do what you want with the address here
}

Don't try to return the results as you will find that they are undefined - a result of an asynchronous service. You must call a function, such as updateAddress();

Answer 5

Got this working in the end using:

var arrAddress = item.address_components;
var itemRoute='';
var itemLocality='';
var itemCountry='';
var itemPc='';
var itemSnumber='';

// iterate through address_component array
$.each(arrAddress, function (i, address_component) {
    console.log('address_component:'+i);

    if (address_component.types[0] == "route"){
        console.log(i+": route:"+address_component.long_name);
        itemRoute = address_component.long_name;
    }

    if (address_component.types[0] == "locality"){
        console.log("town:"+address_component.long_name);
        itemLocality = address_component.long_name;
    }

    if (address_component.types[0] == "country"){ 
        console.log("country:"+address_component.long_name); 
        itemCountry = address_component.long_name;
    }

    if (address_component.types[0] == "postal_code_prefix"){ 
        console.log("pc:"+address_component.long_name);  
        itemPc = address_component.long_name;
    }

    if (address_component.types[0] == "street_number"){ 
        console.log("street_number:"+address_component.long_name);  
        itemSnumber = address_component.long_name;
    }
    //return false; // break the loop   
});

Here's some code you can use with the lodash js library: (just replace the $scope.x with your own variable name to store the value)

    _.findKey(vObj.address_components, function(component) {

            if (component.types[0] == 'street_number') {
                $scope.eventDetail.location.address = component.short_name
            }

            if (component.types[0] == 'route') {
                $scope.eventDetail.location.address = $scope.eventDetail.location.address + " " + component.short_name;
            }

            if (component.types[0] == 'locality') {
                $scope.eventDetail.location.city = component.long_name;
            }

            if (component.types[0] == 'neighborhood') {
                $scope.eventDetail.location.neighborhood = component.long_name;
            }

        });
