    var lng = position.coords.longitude;

    var markerPoint = new google.maps.LatLng(lat, lng);

    var marker = new google.maps.Marker({
        position: markerPoint,
        map: map,
        title: 'Your Location'
    });
}

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

Some security measures might cause that the client won’t share location informations automatically.
