GoogleMaps v3 API Create only 1 marker on click

by 
var marker;

function placeMarker(location) {
  if ( marker ) {
    marker.setPosition(location);
  } else {
    marker = new google.maps.Marker({
      position: location,
      map: map
    });
  }
}

google.maps.event.addListener(map, 'click', function(event) {
  placeMarker(event.latLng);
});

You have to work on the same marker all the time – do not create new ones.
Here you have a global variable marker and in placeMarker function you assign marker to this variable first time. Next time it checks that marker exists already and then just changes its position.
