Hi,

You can do like this please rfer this code

$("#updateMap").click(function(){

    var lat = parseFloat(document.getElementById('markerLat').value);
    var lng = parseFloat(document.getElementById('markerLng').value);
    var newLatLng = new google.maps.LatLng(lat, lng);

    if (marker != undefined)
        marker.setPosition(newLatLng);
    else
        marker = new google.maps.Marker({
            position: newLatLng,
            map: map,
            draggable: true
        });
    });
