Get Current Location

Question

Hi,

I am trying to show the current location on the map. I tried following code:

// Initialize the location provider

vargeoLocationProvider = newMicrosoft.Maps.GeoLocationProvider(map);

// Get the user's current location

geoLocationProvider.getCurrentPosition({ successCallback: displayCenter, showAccuracyCircle:

false});

functiondisplayCenter(args) {

       

// Display the user location when the geo location request returns   

varloc = args.center;

        map.setView({ zoom: 12, center:

newMicrosoft.Maps.Location(loc.latitude, loc.longitude) });

    }

But it works when I run the web application in IE. But if I try to access the application in iPhone/iPad Safari it is not moving to the current location.

Is this the currect approach or is there any other way to get current location?

Also, I tried following way. The second alert is not working in Safari. Any idea?

if (navigator.geolocation) {                        

                        alert(navigator.geolocation.getCurrentPosition);   // works in IE & Safari

                        navigator.geolocation.getCurrentPosition(
                              function (pos) {
                                  alert(navigator.geolocation.getCurrentPosition);  / not works in Safari
                                  var lat = pos.coords.latitude;
                                  var long = pos.coords.longitude;

                                  map.setView({ zoom: 12, center: new Microsoft.Maps.Location(lat, long) });

                              },
                              function () {
                                  alert("Error');
                              }
                            );
                    }

Answer 2

It works fine now. I changed the Location Services to 'ON' for Safari in my iPad

Also you can add errorback in getCurrentPosition method as below: 

geoLocationProvider.getCurrentPosition({ errorCallback: function(object) { alert('Error callback invoked, error code '  + object.errorCode); } });

The error code returned is documented here http://msdn.microsoft.com/en-us/library/hh125839.aspx
