HTML5 and geolocation

Question

I want to get my position each timeinterval using navigator.geolocation.watchPosition Later on I want to store these coordinates in a xml file.

The problem is the watchPosition function does not call the getLocation function.

  function trackCoords ()
  {
      if (navigator.geolocation)
      {

          var options = { frequency: 3000 };
            watchID = navigator.geolocation.watchPosition(getLocation, locationFail, options);
      }


  }



  function getLocation(position) { 
        alert();
        var latitude = position.coords.latitude;
        var longitude = position.coords.longitude;
        alert('latitude: ' + latitude + ' longitude: ' + longitude);
        }

    function locationFail() {
    document.write('We did not get your location');
            }

Thanks in advance

I think you're not calling trackCoords. Does the browser ask you for permission to be geolocalized? If I add trackCoords() at the end of your script it seems to work for me:
