I would like to get the latitude and longitude of current location from gps enabled mobile device right from the web browser. May I know is this possible? how to do it? does it require geolocation api? Some coding example would be helpful. Thanks.

User must willfully provide this information. See the Google home page on mobile. – Hypochlorite 10/8, 2010 at 18:37

Which device? Which API? – Kabuki 10/8, 2010 at 19:16

@josh yes, of course it is assumed that user has approved to share location at the phone settings.. – Ratha 10/8, 2010 at 19:20

Use the HTML5 Geolocation API, here's the official spec and examples.

EDIT

I've updated my answer to include current browser support.

W3C Geolocation API support

Firefox 3.5+
Safari 5.0+
Chrome 5.0+
Opera
iPhone 3.0+
Android 2.0+

· ·
Other phones not listed above use Gears or their own, platform-specific APIs.

Ahh, will we ever have just one single API? :)

Many thanks to Mark Pilgrim for his awesome post.

is it means that html5 geolocation api can be used by all gps enabled devices? thanks.. – Ratha 11/8, 2010 at 7:34

Google Gears is long deprecated. – Chelyuskin 10/1, 2013 at 21:35

This does not work on mobile networks or Chrome (only https) or Safari. I use ipinfo.io which is ok for wifi connected devices but returns lat long of networks ISP. – Stifling 1/12, 2016 at 11:56

Here is an actual JavaScript code which uses HTML5 Geolocation API. The following works on both Android browser and iPhone Safari:

            function onPositionUpdate(position)
            {
                var lat = position.coords.latitude;
                var lng = position.coords.longitude;
                alert("Current position: " + lat + " " + lng);
            }

            if(navigator.geolocation)
                navigator.geolocation.getCurrentPosition(onPositionUpdate);
            else
                alert("navigator.geolocation is not available");

You don’t have to have the newest mobile phone to use GPS and Geolocation API. Almost every mobile browser (without proxy server) can be used to read position from buidin GPS. If You have Java and GPS in Your phone – You can use mobile-gps-web-gate – see at http://code.google.com/p/mobile-gps-web-gate/

<script>
var x = document.getElementById("demo");
function getLocation() {
    if (navigator.geolocation) {
        navigator.geolocation.getCurrentPosition(showPosition);
    } else { 
        x.innerHTML = "Geolocation is not supported by this browser.";
    }
}
function showPosition(position) {
 var a = position.coords.latitude + ',' + position.coords.longitude;

 alert(a);
}
