Hi I have this code on my javascript file that add a marker to a google map and i want an info window to appear when positioning the marker. Any one can help me accomplish this.

Thanks


var marker;   
     
function addMarker(location) {
  if ( marker ) {
    marker.setPosition(location);
  } else {
    marker = new google.maps.Marker({
     position: location,
     map: map,
     icon: imageBlue,
     draggable: true
    });
  }
  markersArray.push(marker);
}
  
google.maps.event.addListener(map, 'click', function(event) {
    addMarker(event.latLng);
  });
  
 google.maps.event.addListener(marker, 'click', function() {
   dragInfoWindow.open(map,marker);
});
dragInfoWindow.open(map,marker);
