AutocompleteService: componentRestrictions doesn't seem to be functional

[gotofritz]

Hi. A simple AutocompleteService request.

Loading this API:

https://maps.googleapis.com/maps/api/js?v=3.21&libraries=places&callback= onAPILoaded

And running this script (sorry, tried to do a JSBin http://jsbin.com/sujatuzaro/edit?html,js,output  but it won't load the API)

function runQuery(country) {

  var request = {

    input: 'london',

    componentRestrictions: {country: country},

  };

  var callback = function(predictions, status) {

    if (status != google.maps.places.PlacesServiceStatus.OK) {

      alert(status);

      return;

    }

    var resultsString = predictions.reduce(function (prev, current) {

      return prev + "\n" + current.description;

    }, "RESULTS FOR " + country + "\n--------------\n");

    console.log(resultsString);

  };

  var service = new window.google.maps.places.AutocompleteService();

  service.getQueryPredictions(request, callback);

}

function onAPILoaded() {

  runQuery('uk');

  runQuery('ca');

}

I get the following output:

RESULTS FOR uk

--------------

London, United Kingdom

London, ON, Canada

London Borough of Hillingdon, United Kingdom

London Eye, London, United Kingdom

London Bridge, London, United Kingdom

RESULTS FOR ca

--------------

London, United Kingdom

London, ON, Canada

London Borough of Hillingdon, United Kingdom

London Eye, London, United Kingdom

London Bridge, London, United Kingdom

RESULTS FOR uk

--------------

London, United Kingdom

London, ON, Canada

London Borough of Hillingdon, United Kingdom

London Eye, London, United Kingdom

London Bridge, London, United Kingdom

....

The problem is not that they are repeated a few times (although that is odd) but the fact the componentRestrictions doesn't seem to have any effect.

Any idea? Thanks in advance.

Heya :)

This group is used primarily for announcements now; for questions like this I recommend Stack Overflow instead. There's a maps-api-v3 and places-api tag which will bring this to the attention of the best people.

In the meantime, try using getPlacePredictions rather than getQueryPredictions. This appears to apply the restriction correctly. 

Cheers,

James
