Googe places autocomplete implementation using Twitter bootstrap typeahead and google's autocomplete and geocoding services

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

$(field).typeahead({
  source: function(query, process) {
    service.getPlacePredictions({ input: query }, function(predictions, status) {
      if (status == google.maps.places.PlacesServiceStatus.OK) {
        process($.map(predictions, function(prediction) {
          return prediction.description;
        }));
      }
    });
  },
  updater: function (item) {
    geocoder.geocode({ address: item }, function(results, status) {
      if (status != google.maps.GeocoderStatus.OK) {
        alert('Cannot find address');
        return;
      }
      map.setCenter(results[0].geometry.location);
      map.setZoom(12); 
    });
    return item;
  }
});

@badsyntax is there a repo for your jquery.places-search ?

Thanks for this, @badsyntax. For anyone else dealing with missing results using this example, I found a small issue where valid results whose names do not contain the query are not displayed. For example, try searching for "mcdonald's nyc" in the demo and you will notice no results are returned, while the same search returns five results on Google's autocomplete example.

To fix this, override Typehead's default matcher function, which hides results whose names do not contain the query, by adding a matcher function to the $.typeahead's call like so:

matcher: function (item) {
    return true;
}

@ScotterC I have not created a repo for this code. If you would like to do so, feel free to use my code.

To everyone else, I wanted to create a bootstrap 3 version, but I'm quite disappointed that Bootstrap 3 dropped the typeahead plugin.

I'm really grumpy about this, because the new "fancy" typeahead.js plugin is just another typical bloated jquery plugin and is NOT a drop-in replacement for bootstrap 2.3.0 typeahead.

Seriously, there's no API methods to build up the list of suggestions manually. The plugin expects a data source, and it expects to do all the filtering within a large data set. Whereas with the Google Places API, the API itself does all the filtering and just returns the suggestions. I can't combine the two. I can't manually add the list of suggestions. Such a fancy plugin, so very useless.

If you want to use the typeahead with google's autocomplete with Bootstrap 3, you will have to use Bootstrap 2.3.0 typeahead.

I willl update this gist if/when typeahead.js provides a simple API method for building the list of suggestions manually.

I completely agree...I've been trying to migrate my old bootstrap code using autocomplete and typeahead to 3.0 but it has been a nightmare! Has anyone else had any luck in doing so?

Found a hack fpr the new typeahead so that suggestions can be provided using a callback method again.
It goes something like this:

(t = $("field")).typeahead({ local: [] });
t.data("ttView").datasets[0].getSuggestions = function(query, callback) {
  var suggestions = ... gather your suggestions here ...
  var data = [];
  for (suggestion in suggestions) { data.push(this._transformDatum(suggestion)); }
  callback(data)
}

Guess this should allow you to use autocomplete again easily.

this is great. many thanks!

I am however wrecking my brain trying to port your example to the latest twitter typeahead.js instead of the bootstrap 2 version. help?

@ficshelf read the comments in this thread, it's not possible without hacks.

@svub Where do i need to put your code so that autocomplete would work again ? Can't find place where to put it.

Just in case anyone get to this page in the future, as it's like second when googling typeahead with gmaps.

It's totally possible to make typeahead works with google maps easily without hacks :

var geocoder = new google.maps.Geocoder();

$('.typeahead').typeahead({
    autoselect: true,
    sections: [{
        name: 'google',
        minLength: 4,
        templates: {
            header: '<h5 class="typeahead-header">Google Results</h5>'
        },
        source: function (q, value) {
            geocoder.geocode({ address: q }, function (results, status) {

                value($.map(results, function (result) {
                    retval = [];
                    retval.push({ value: result.formatted_address });
                    return retval;
                }));
            });
        }
  }]
});

Couldn't get that to work @Azaret .. No errors, typeahead is initialized, but no dropdown with results.

thx for sharing! :)

@badsyntax You created a project for it on google developer console and assigned the demo an API key.... then you deleted the project. Probably best just not to have given it an API key in the first place

I think it will be a little late to answer @ronnyandre :) But this would be better. And moreover if any map on page it would be fit bounds to selected suggestions geometry

var geocoder = new google.maps.Geocoder();
$('.typeahead').typeahead({
                                            autoselect: true,
                                                minLength: 4,
                                              },{
                                                name: 'google',
                                                displayKey: 'address',
                                                templates: {
                                                    header: '<h5 class="typeahead-header">Google Results</h5>'
                                                },
                                                source: function (q, sync, async){
                                                    geocoder.geocode({ address: q }, function (results, status) {
                                                      for (var i = results.length - 1; i >= 0; i--) {
                                                        async([{address:results[i].formatted_address, geometry:results[i].geometry}]);
                                                      }
                                                    });
                                                }
                                          }
                                        ).on('typeahead:selected', function (obj, datum) {
                                            if(datum)
                                            {
                                              var geometry = datum.geometry;
                                               map.fitBounds(geometry.bounds? geometry.bounds : geometry.viewport);
                                            }
                                        });
