| ## Parametri |
| |
| * **geolocationSuccess**: il callback passato alla posizione corrente. |
| |
| * **geolocationError**: *(facoltativo)* il callback che viene eseguito se si verifica un errore. |
| |
| * **geolocationOptions**: *(opzionale)* le opzioni di geolocalizzazione. |
| |
| ## Descrizione |
| |
| `geolocation.getCurrentPosition`è una funzione asincrona. Restituisce la posizione corrente del dispositivo per la `geolocationSuccess` callback con un `Position` oggetto come parametro. Se c'è un errore, il `geolocationError` callback viene passata una `PositionError` oggetto. |
| |

| |
| * Android |
| * BlackBerry WebWorks (OS 5.0 e superiori) |
| * iOS |
| * Tizen |
| * Windows Phone 7 e 8 |

| ## Esempio rapido |
| |
| // onSuccess Callback |
| // This method accepts a Position object, which contains the |
| // current GPS coordinates |
| // |
| 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: ' + 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); |
