How do I make an infowindow automatically display as open with Google-Maps-for-Rails

Question

I want to display a map with the infowindow box automatically displayed for the single marker on the page, much like http://code.google.com/apis/maps/documentation/javascript/ex

Answer 1

The callback function that worked for me:

Gmaps.map.callback = function() {
      function openInfoWindow(){
        var m, marker;
        marker = Gmaps.map.markers[2];
        m = marker.serviceObject;
        marker.infowindow.open(Gmaps.map.map, m);
      }
      openInfoWindow();
}
