This library was modified by jcdelgado to update locations automatically at marker drag.

To convert an input into an autocomplete field, simply call the Geocomplete plugin:
$("input").geocomplete(); // Option 1: Call on element.
$.fn.geocomplete("input"); // Option 2: Pass element as argument.Here is a list of basic uses:
- Simple - Single input with an event logger.
- Map - Adding a map.
- Location - Adding a default location.
- Form - Populate form fields.
- Attribute - Using custom attributes to populate data.
- Multiple results - Handling multiple results from the geocoder.
- Draggable - A draggable marker to redefine the position.
Make sure you include the Google Maps API with the Places Library before loading this plugin as described here.
<script src="http://maps.googleapis.com/maps/api/js?sensor=false&libraries=places"></script>
<script src="jquery.geocomplete.js"></script>
```
If you use the plugin without showing a map you must display the "[powered by Google](https://developers.google.com/maps/documentation/javascript/places#autocomplete_no_map)" logo under the text field.
## Trigger Request
To trigger a geocoding request from outside (eg. when hitting the "find" button), simply trigger the "geocode" event on the element.
````javascript
$("input").geocomplete();
// Trigger geocoding request.
$("button.find").click(function(){
$("input").trigger("geocode");
});
```
## Adding a Map Preview
To link the geocode results with an interactive map, you can pass `map` as an option to the plugin.
```javascript
$("#my_input").geocomplete({
map: "#my_map"
});
```
The `map` option might be a selector, a jQuery object or a DOM element.
## Populate Form Data
You can pass `details` as an option to specify a cointainer that will be populated when a geocoding request was successfull.
By default the plugin analyses the `name` attribute of the containers child nodes and replaces the content. You can override the `detailsAttribute` to use another attribute such as `data-geo`.
If the element is an input, the value will be replaced otherwise the plugin overrides the current text.
**Note**: Some address compontents such as "country" return an additional `short_name`. You can access them by simply adding `_short` at the end of the type.
Simple Example:
```html
<form>
Latitude: <input name="lat" type="text" value="">
Longitude: <input name="lng" type="text" value="">
Address: <input name="formatted_address" type="text" value="">
</form>
```
```javascript
$("input").geocomplete({ details: "form" });
```
Advanced Example:
```html
<div class="details">
Latitude: <span data-geo="lat" />
Longitude: <span data-geo="lng" />
Address: <span data-geo="formatted_address" />
Country Code: <span data-geo="country_short" />
</div>
```
```javascript
$("input").geocomplete({
details: ".details",
detailsAttribute: "data-geo"
});
```
## List of Options
The following options might be passed to the plugin call. If you omit them, they fall back to the default.
Example:
```javascript
$("#my_input").geocomplete({
map: "#my_map",
mapOptions: {
zoom: 10
},
markerOptions: {
draggable: true
},
details: "#my_form"
});
```
* `map` - Might be a selector, a jQuery object or a DOM element. Default is `false` which shows no map.
* `details` - The container that should be populated with data. Defaults to `false` which ignores the setting.
* `location` - Location to initialize the map on. Might be an address `string` or an `array` with [latitude, longitude] or a `google.maps.LatLng`object. Default is `false` which shows a blank map.
* `bounds` - Whether to snap geocode search to map bounds. Default: `true` if false search globally. Alternatively pass a custom LatLngBounds object
* `detailsAttribute` - The attribute's name to use as an indicator. Default: `"name"`
* `mapOptions` - Options to pass to the `google.maps.Map` constructor. See the full list [here](http://code.google.com/apis/maps/documentation/javascript/reference.html#MapOptions).
* `mapOptions.zoom` - The inital zoom level. Default: `14`
* `mapOptions.scrollwheel` - Whether to enable the scrollwheel to zoom the map. Default: `false`
* `mapOptions.mapTypeId` - The map type. Default: `"roadmap"`
* `markerOptions` - The options to pass to the `google.maps.Marker` constructor. See the full list [here](http://code.google.com/apis/maps/documentation/javascript/reference.html#MarkerOptions).
* `markerOptions.draggable` - If the marker is draggable. Default: `false`. Set to true to enable dragging.
* `markerOptions.disabled` - Do not show marker. Default: `false`. Set to true to disable marker.
* `maxZoom` - The maximum zoom level to zoom in after a geocoding response. Default: `16`
* `componentRestrictions` - Option for Google Places Autocomplete to restrict results by country. See the [docs](https://developers.google.com/maps/documentation/javascript/places#places_autocomplete)
* `types` - An array containing one or more of the supported types for the places request. Default: `['geocode']` See the full list [here](http://code.google.com/apis/maps/documentation/javascript/places.html#place_search_requests).
* `blur` - Defaults to `false`. When enabled it will trigger the geocoding request whenever the geofield is blured. (See jQuery `.blur()`)
## Events
You can subscribe to events of the geocode plugin by using the default jQuery syntax:
````javascript
$("input")
.geocomplete()
.bind("geocode:result", function(event, result){
console.log(result);
});
```
The following events are supported:
* `"geocode:result"` - Geocode was successful. Passes the original result as described [here](http://code.google.com/apis/maps/documentation/javascript/geocoding.html#GeocodingResults).
* `"geocode:error"` - Fired when the geocode returns an error. Passes the current status as listed [here](http://code.google.com/apis/maps/documentation/javascript/geocoding.html#GeocodingStatusCodes).
* `"geocode:multiple"` - Fired immediately after the "result" event if multiple results were found. Passes an array of all results.
* `"geocode:dragged"` - Fired when the marker's position was modified manually. Passes the updated location.
* `"geocode:click"` - Fired when 'click' event occurs on the map. Passes the location where the click had place.
## Methods and Properties
You can access all properties and methods of the plugin from outside. Simply add a string as the first argument to the `.geocomplete` method after you initialized the plugin.
Example:
````javascript
// Initialize the plugin.
$("input").geocomplete({ map: ".map_canvas" });
// Call the find method with the paramenter "NYC".
$("input").geocomplete("find", "NYC");
// Get the map and set a new zoom level.
var map = $("input").geocomplete("map");
map.setZoom(3);
```
## Address and Places Specific Component Types
The following types are supported by the geocoder and will be passed to the provided form or container:
`street_address`, `route`, `intersection`, `political`, `country`, `administrative_area_level_1`, `administrative_area_level_2`, `administrative_area_level_3`, `colloquial_area`, `locality`, `sublocality`, `neighborhood`, `premise`, `subpremise`, `postal_code`, `natural_feature`, `airport`, `park`, `point_of_interest`, `post_box`, `street_number`, `floor`, `room`, `lat`, `lng`, `viewport`, `location`, `formatted_address`, `location_type`, `bounds`
For more information about address components visit http://code.google.com/apis/maps/documentation/geocoding/#Types
Additionally the following details are passed when the Places API was requested:
`id`, `url`, `website`, `vicinity`, `reference`, `rating`, `international_phone_number`, `icon`, `formatted_phone_number`
