drpozitiff,
может так?

<input type="text" id="address"  value="Хмельницьке шосе, 13">

function geocodeAddress(geocoder, resultsMap) {
    var address = document.getElementById('address').value;
    var infowindow = new google.maps.InfoWindow({
            content: address
    });
    geocoder.geocode({'address': address}, function(results, status) {
    if (status === google.maps.GeocoderStatus.OK) {
        resultsMap.setCenter(results[0].geometry.location);
        marker = new google.maps.Marker({
            map: resultsMap,
            position: results[0].geometry.location,
            title: address,
            draggable: false
        });
       infowindow.open(resultsMap, marker);


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