I got strange behavior when I tried to test my
“navigator.geolocation.getCurrentPosition” web page. Here is my
testing result and code:

my code:

function detectLocation() 
{
  if (navigator.geolocation) 
  {
    navigator.geolocation.getCurrentPosition(geocodePosition, onError, { timeout: 30000 });
    navigator.geolocation.watchPosition(watchGeocodePosition);
  } 
  else 
  {
    onError();
  }
}

this function was run when “body” onload event was called. I had tried to change the timeout to 10000 and 20000, but I still got same result. I also allowed crome and firefox to get my location.

result:

  1. Using chrome (v 17.0.963.79 m), result always went to onError
    function when navigator.geolocation.getCurrentPosition was called.
  2. Using Firefox (v 10.0.2), result always went to onError function
    when navigator.geolocation.getCurrentPosition was called.
  3. Using IE (v 9), result was fantastic, I got my current location.

can anyone help me in this strange situation? I really didn’t have any idea to solve this problem and I was in hurry on my project deadline. Thanks before.

EDIT :
For this couple days I got some progress, the error code code is 2 with a message “Network location provider at ‘https://maps.googleapis.com/maps/api/browserlocation/json?browser=chromium&sensor=true’ : Response was malformed”. Still unsolved, does anyone know how to solve this?

    I simulated this problem and found that the success callback functions were only called when the html page was hosted on a web server and not when opened from a filesystem.

    To test I opened the file directly from my C: drive and it the callbacks didn’t work and then hosted the file on Internet Information Services (IIS) and the callbacks did work.

    <html>
<body onload="detectLocation()">
<!-- This html must be hosted on a server for navigator.geolocation callbacks to work -->

<div id="status"></div>

<script type="text/javascript">
function detectLocation()
{
  log("detectLocation() starting");
  if (navigator.geolocation)
  {
    log("navigator.geolocation is supported");
    navigator.geolocation.getCurrentPosition(geocodePosition, onError, { timeout: 30000 });
    navigator.geolocation.watchPosition(watchGeocodePosition);
  }
  else
  {
    log("navigator.geolocation not supported");
  }
}
function geocodePosition(){
    log("geocodePosition() starting");
}

function watchGeocodePosition(){
    log("watchGeocodePosition() starting");
}

function onError(error){
    log("error " + error.code);
}
function log(msg){
    document.getElementById("status").innerHTML = new Date() + " :: " + msg + "<br/>" + document.getElementById("status").innerHTML;
}
</script>
</body>
</html>
