Nice article here:

if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition( 

    function (position) {  

    // Did we get the position correctly?
    // alert (position.coords.latitude);

    // To see everything available in the position.coords array:
    // for (key in position.coords) {alert(key)}

    alert(position.coords.latitude + ',' + position.coords.longitude);

    }, 
    // next function is the error callback
    function (error)
    {
        switch(error.code) 
        {
            case error.TIMEOUT:
                alert ('Timeout');
                break;
            case error.POSITION_UNAVAILABLE:
                alert ('Position unavailable');
                break;
            case error.PERMISSION_DENIED:
                alert ('Permission denied');
                break;
            case error.UNKNOWN_ERROR:
                alert ('Unknown error');
                break;
        }
    }
    );
}

}
