Geolocation

Description

The Geolocation interface represents an object able to programmatically obtain the position of the device. It gives Web content access to the location of the device. This allows a Web site or app to offer customized results based on the user's location. Notice that 'geolocation' permission is required for packaged app to use Geolocation API. (i.e. The developer must add the permisson to the manifest.webapp)

An object with this interface is obtained using the navigator.geolocation property implemented by the Navigator object.

void getCurrentPosition(PositionCallback successCallback,

optional PositionErrorCallback? errorCallback = null,
