Mobile GPS

[needsomehelp]

I am trying to get a fix on mobile devices, of course if they agree to their location to be given out.

Just like some websites ask if my pc's location can be given out. But when I allow my pc's location it always shows a location in London, being my ISP, which must mean that the location is got using my IP address.

Can anyone suggest how I can go about getting the exact or near exact location of mobile devices that connect to my site. Would it be using PHP and HTML or Javascript ? I have no idea where to start.

javascript.
check out this doc: http://dev.w3.org/geo/api/spec-source.html
and here's nice demo with sources on github: http://html5demos.com/geo

location is accessed via javascript obviusly. and then you do whatever you want with it

basically it's

<script language="javascript">
function successCallback(data){
	document.writeln('accuracy: ' + data.coords.accuracy + '<br />');
	document.writeln('altitude: ' + data.coords.altitude + '<br />');
	document.writeln('altitude accuracy: ' + data.coords.altitudeAccuracy + '<br />');
	document.writeln('heading: ' + data.coords.heading + '<br />');
	document.writeln('latitude: ' + data.coords.latitude + '<br />');
	document.writeln('longitude: ' + data.coords.longitude + '<br />');
	document.writeln('speed: ' + data.coords.speed + '<br />');
	document.writeln('timestamp: ' + data.timestamp);
}

function errorCallback(data){
	document.writeln('error');
}

if(navigator.geolocation){
	navigator.geolocation.getCurrentPosition(successCallback, errorCallback);
}else{
	document.writeln('not supported');
}
</script>

yes it's that simple. paste it INSIDE document's body and open
