How to get the country code from Google Places API

To get the country code, get the short name of the address component with type country:

// for the country, get the country code (the "short name") also
if (addressType == "country") {
  document.getElementById("country_code").value = place.address_components[i].short_name;
}

code snippet:

// This example displays an address form, using the autocomplete feature
// of the Google Places API to help users fill in the information.

function fillInAddress() {
  // Get the place details from the autocomplete object.
  var place = autocomplete.getPlace();

  for (var component in componentForm) {
    document.getElementById(component).value = '';
  }

  // Get each component of the address from the place details
  // and fill the corresponding field on the form.
  for (var i = 0; i < place.address_components.length; i++) {
    var addressType = place.address_components[i].types[0];
    if (componentForm[addressType]) {
      var val = place.address_components[i][componentForm[addressType]];
      document.getElementById(addressType).value = val;
    }
    // for the country, get the country code (the "short name") also
    if (addressType == "country") {
      document.getElementById("country_code").value = place.address_components[i].short_name;
    }
  }
}

var placeSearch, autocomplete;
var componentForm = {
  locality: 'long_name',
  administrative_area_level_1: 'short_name',
  country: 'long_name',
};

function initAutocomplete() {
  // Create the autocomplete object, restricting the search to geographical
  // location types.
  autocomplete = new google.maps.places.Autocomplete(
    /** @type {!HTMLInputElement}     */
    (document.getElementById('autocomplete')), {
      types: ['(cities)']
    });

  // When the user selects an address from the dropdown, populate the address
  // fields in the form.
  // Get Latitude and longitude
  google.maps.event.addListener(autocomplete, 'place_changed', function() {
    var place = autocomplete.getPlace();
    document.getElementById('lat').value = place.geometry.location.lat();
    document.getElementById('lng').value = place.geometry.location.lng();
    fillInAddress();
  });
}
google.maps.event.addDomListener(window, 'load', initAutocomplete);

You will get postal code, country, state, city and other with using below function. 

export let placeAddresCompoponent = {
    ZIP_CODE: 'postal_code',
    COUNTRY: 'country',
    STATE: 'administrative_area_level_1',
    CITY: 'administrative_area_level_2',
    TOWN: 'sublocality_level_1',
    AREA: 'sublocality_level_2',
    NEAREST_ROAD: 'route'
}

Use the below function for getting data from the address component. You will get address_components from the result of Google Place Api.

export function getAddressComponent(address_components, key) {
    var value='';
    var postalCodeType = address_components.filter(aComp =>
        aComp.types.some(typesItem => typesItem === key))
    if (postalCodeType != null && postalCodeType.length > 0)
        value = postalCodeType[0].long_name
    return value;
}

You can get the specific address component using below.

addressComponent = Array of address_components from google place api result

var zipCode = getAddressComponent(addressComponent, placeAddresCompoponent.ZIP_CODE)
var country = getAddressComponent(addressComponent, placeAddresCompoponent.COUNTRY)
console.log('zipCode : ', zipCode)
console.log('country : ', country)
