markerclusterer info windows

Question

Let me say I am still fairly new to google maps and javascript. i\'ve been mixing together the google store locator tutorial with some other stuff. So far, I am using mark

Answer 1

infoWindow.Open has two overloads

 infoWindow.Open(map, marker)
 infoWindow.Open(map)

Since you wanto to add it to a cluster (not a marker) you should use the second one

You must set the position getting the center of the cluster

google.maps.event.addListener(markerCluster, "mouseover", function (mCluster) {    
    infowindow.content += "
Something<\/div>";
    infowindow.setPosition(mCluster.getCenter());
    infowindow.open(map);
});

I know it works because I just did it
