Selecting a marker by default using Google-Maps-for-Rails

I have a map with markers, and I need to select one marker by dafault, like shown below. Is this possible using gmaps4rails?

enter image description here

Ok here is what worked for me:

      Gmaps.map.callback = function() {
        if (Gmaps.map.markers.length == 1) {
         //only one marker, choose the zoom level you expect
         setTimeout(function() { Gmaps.map.serviceObject.setZoom(15);}, 50);
        }
        else{
         //more than one marker, let's auto_zoom
         Gmaps.map.map_options.auto_zoom = true;
         Gmaps.map.adjustMapToBounds();
        }
        // focus on first marker
        marker = Gmaps.map.markers[0]
        setTimeout(function() { google.maps.event.trigger(marker.serviceObject, 'click') }, 250);  
      }
Solution

  • 1.5.6 is not that convenient, but:

    First get your marker (should live in Gmaps.map.markers)

    Then:

     google.maps.event.trigger(marker.serviceObject, 'click')
