javascript - Get only countries to autocomplete from Google Maps API

Question

I'm using Google Maps API to get autocomplete list of cities and countries (without other details), and it works exellent.

var input = document.getElementById('newAddress');
    var options = {
        types: ['(cities)']
    };

    autocomplete = new google.maps.places.Autocomplete(input, options);

Now I want to do exactly the same but to get only countries names. Somthing like replacing types: ['(cities)'] with types: ['(countries)']...
(what I tried but didn't work)

What should I do in order to get only countries into my autocomplete?

I've been playing around with the Google Autocomplete API for a bit and here's the best solution I could find for limiting your results to only countries:

var autocomplete = new google.maps.places.Autocomplete(input, options);
var result = autocomplete.getPlace();
console.log(result); // take a look at this result object
console.log(result.address_components); // a result has multiple address components

for(var i = 0; i < result.address_components.length; i += 1) {
  var addressObj = result.address_components[i];
  for(var j = 0; j < addressObj.types.length; j += 1) {
    if (addressObj.types[j] === 'country') {
      console.log(addressObj.types[j]); // confirm that this is 'country'
      console.log(addressObj.long_name); // confirm that this is the country name
    }
  }
}

If you look at the result object that's returned, you'll see that there's an address_components array which will contain several objects representing different parts of an address. Within each of these objects, it will contain a 'types' array and within this 'types' array, you'll see the different labels associated with an address, including one for country.
