Position

Contains Position coordinates that are created by the geolocation API.

Properties

  • coords: A set of geographic coordinates. (Coordinates)
  • timestamp: Creation timestamp for coords in milliseconds. (DOMTimeStamp)

Description

The Position object is created and populated by Cordova, and returned to the user through a callback function.

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iPhone
  • Windows Phone 7 ( Mango )

Quick Example

// onSuccess Callback
//
var onSuccess = function(position) {
    alert('Latitude: '          + position.coords.latitude          + '\n' +
          'Longitude: '         + position.coords.longitude         + '\n' +
          'Altitude: '          + position.coords.altitude          + '\n' +
          'Accuracy: '          + position.coords.accuracy          + '\n' +
          'Altitude Accuracy: ' + position.coords.altitudeAccuracy  + '\n' +
          'Heading: '           + position.coords.heading           + '\n' +
          'Speed: '             + position.coords.speed             + '\n' +
          'Timestamp: '         + new Date(position.timestamp)      + '\n');
};

// onError Callback receives a PositionError object
//
function onError(error) {
    alert('code: '    + error.code    + '\n' +
          'message: ' + error.message + '\n');
}

navigator.geolocation.getCurrentPosition(onSuccess, onError);

iPhone Quirks

  • timestamp: Uses seconds instead of milliseconds.

A workaround is to manually convert the timestamp to milliseconds (x 1000):

    var onSuccess = function(position) {
        alert('Latitude: '  + position.coords.latitude             + '\n' +
              'Longitude: ' + position.coords.longitude            + '\n' +
              'Timestamp: ' + new Date(position.timestamp * 1000)  + '\n');
    };
