Windows Phone 7 IE - Get GPS Coordinates From Mobisite

I use the following code to get the GPS coordinates on a Android/iOS device from a mobisite but it doesn't work on WP7.

How can I get a user's GPS coordinates in IE on a WP7 device? (I am testing on a Samsung Omnia 7).

<script language="javascript">
    navigator.geolocation.getCurrentPosition(findLocation, noLocation);

    function findLocation(position)
    {
        var lat = position.coords.latitude;
        var lng = position.coords.longitude;
        document.getElementB开发者_JAVA技巧yId("result").innerHTML = "Lat: " + lat + ", Long: " + lng;
    }

    function noLocation()
    {
        document.getElementById("result").innerHTML = "Unable to get location";
    }
</script>

What happens when you run this on a WP7 device?

When are you running this? Be sure to do it after the document has loaded.

If you're running this inside a WebBrowser control then be sure to set IsGeolocationEnabled to true.

ALso check that location is enabled on the device and in IE.

The error callback should contain a positionError parameter which may give you more information about any error.
