Example of adding google map API to typeahead jquery plugin to display address autocomplete suggestions.
npm install typeahead-addresspickerIt'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.

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
``html`
2) Add an input text
`html`
3) Instanciate an AddressPicker and a typeahead
`js
var addressPicker = new AddressPicker();
$('#address').typeahead(null, {
displayKey: 'description',
source: addressPicker.ttAdapter()
});
`
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
`html`
3) Instantiate an AddressPicker with the google map div element or ID and connect typeahead events.
`js
// 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);
`
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:
js `
{
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:
js `
{
draggable: true,
visible: false,
position: MAP_CENTER
}
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:
`js `
{
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 the getDetails portion to speed up the query (default: false).
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:
`js
// 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'));
});

The code is tested as much as possible. If you want to add features, please add spec in your pull request.
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.
* 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.
