Did you have already Geolocation Support?

function FindLocaiton() {
geocoder = new google.maps.Geocoder();
InitializeMap();

    var address = document.getElementById("addressinput").value;
    geocoder.geocode({ 'address': address }, function (results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            map.setCenter(results[0].geometry.location);
            var marker = new google.maps.Marker({
                map: map,
                position: results[0].geometry.location
            });

        }
        else {
            alert("Geocode was not successful for the following reason: " + status);
        }
    });

}

Hi valentasm1, i did not mean the google api geolocation.
i mean read out the current location direct from the browser

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) {
x.innerHTML = "Latitude: " + position.coords.latitude +
"
Longitude: " + position.coords.longitude;
}

It is not related to library at all.
