sgruhierTypeahead Address Picker 
It's not an extension of typeahead plugin itself, but a new data source for twitter typeahead (version > 0.10.0)
The AddressPicker is a subclass of a Bloodhound class. It connects suggestions to Google Map AutocompleteService.
But it's much more than a simple suggestion engine because it can be linked to a google map to display/edit location.
How to use
Without a Google Map
The simplest usage is to use it as suggestion engine, without displaying results on google map.
1) Include typeahead and google map with places activated
<script src="http://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js"></script>
<script src="../dist/typeahead.js"></script>
<script src="../dist/typeahead-addresspicker.js"></script>2) Add an input text
<input id="address" type="text" placeholder="Enter an address">3) Instanciate an AddressPicker and a typeahead
var addressPicker = new AddressPicker();
$('#address').typeahead(null, {
displayKey: 'description',
source: addressPicker.ttAdapter()
});With a Google Map
For a better user experience, you can connect it to a google map to display results.
You just need to add a div as for a google map place holder and connect it to the AddressPicker
1) As before
2) Add a div
<input id="address" type="text" placeholder="Enter an address">
<div id="map"></div>3) Instantiate an AddressPicker with the google map div element or ID and connect typeahead events.
// instantiate the addressPicker suggestion engine (based on bloodhound)
var addressPicker = new AddressPicker({
map: {
id: '#map'
}
});
// instantiate the typeahead UI
$('#address').typeahead(null, {
displayKey: 'description',
source: addressPicker.ttAdapter()
});
// Bind some event to update map on autocomplete selection
$('#address').bind('typeahead:selected', addressPicker.updateMap);
$('#address').bind('typeahead:cursorchanged', addressPicker.updateMap);Options
When you instantiate a new AddressPicker you can pass a list of options new AddressPicker(options)
Available Options:
map(Hash): Map id and options to link typeahead to a goggle map (default: none).id(String/Element) DOM map element or CSS selector- all google.maps.Map constructor options. Default values are:
{ zoom: 3, center: new google.maps.LatLng(0, 0), mapTypeId: google.maps.MapTypeId.ROADMAP }
marker(Hash): Marker options display on the map.- All google.maps.Marker constructor options.
Default values are:
{ draggable: true, visible: false, position: MAP_CENTER }
- All google.maps.Marker constructor options.
Default values are:
autocompleteService(Hash) : options passed to google.maps.places.AutocompleteService#getPlacePredictions (default:{types: ['geocode']}) For more details read Google documentation. You can add a lot of options, like get only address for a country, or get only cities.Example To get only cities in United States:
{ autocompleteService: { types: ['(cities)'], componentRestrictions: { country: 'US' } } }zoomForLocation(Number): Zoom value when an accurate address is selected (default: 16).reverseGeocoding(Boolean): Reverse geocoding when marker is dragged on map (default: false).placeDetails(Boolean): If not using with a map, you can skip thegetDetailsportion to speed up the query (default: false).
Events
Only one event is trigger by AddressPicker object: addresspicker:selected.
The event is fired when an address is selected or when the marker is dragged. If reverseGeocoding is activated, a full response is trigger, otherwise only lat/lng.
To simplify google response parsing, we fire an object of type AddressPickerResult with some accessors:
lat()lng()addressTypes()addressComponents()nameForType: (type, shortName = false)
Listen that event to get values you need and store them in your form. Here is an example:
// Proxy inputs typeahead events to addressPicker
addressPicker.bindDefaultTypeaheadEvent($('#address'))
// Listen for selected places result
$(addressPicker).on('addresspicker:selected', function (event, result) {
$('#your_lat_input').val(result.lat());
$('#your_lng_input').val(result.lng());
$('#your_city_input').val(result.nameForType('locality'));
});Tests
The code is tested as much as possible. If you want to add features, please add spec in your pull request.
Demo
A demo is included in the github repository, and is available here: http://sgruhier.github.io/typeahead-addresspicker
Quick example to show how to use twitter typeahead autocomplete and google map API to make an address picker.
This example is just a first try and could be enhanced to fully replace my previous address picker: http://xilinus.com/jquery-addresspicker/demos/
Any suggestions (using issues) or pull requests are welcome.
Todo
- Connect HTML5 geolocalisation API to display user position
- Anything else that could make sense to be added :). You can open an issue with a label "feature" to open a discussion on a feature/API you'd like to add.
