Google Maps Loader is a JSONP wrapper for loading the Google Maps Javascript API. It provides a simple interface for loading extra libraries, localization, and versioning.

This module has recently been updated with API changes. Y.GoogleMapsLoader is now a regular class extending Base instead of a singleton instance.

Y.GoogleMapsLoader has two public attributes.
source: the location of the Google Maps Javascript API. Defaults to 'http://maps.google.com/maps/api/js'
timeout: the timeout used by JSONP. Defaults to 30 seconds.

Y.GoogleMapsLoader has three public events.
failure: fired when JSONP fails to load the Google Maps Javascript API.
success: fireOnce: fired when the Google Maps Javascript API is loaded.
timeout: fired when JSONP times out.

Y.GoogleMapsLoader has two public methods.
isLoaded: returns boolean.
load: loads the Google Maps Javascript API. (Does nothing if already loaded.)

The load method accepts an optional parameters object. The parameters object may include any of these optional members.

client: This is your client id when using Google Maps API for Business
key: This is your Google Maps v3 API key.
language: the language code to override the browser's default language.
libraries: an array or comma separated list of library names.
region: a Unicode region subtag identifier to override the default region.
sensor: set this to true if your application determines the user's location via a sensor .
source: location of the Google Maps Javascript API to override the attribute.
timeout: timeout in milliseconds to override the attribute.
version: the version of the Google Maps Javascript API to load.
