Hi, Ben.
I had the same challenge, and after some experimentation, I came up
with a very easy and extensible solution which involves extending the
Marker class.
First of all, you can use the event.target to determine which Marker
was the source of the event. Next, you need a way to attach some user
data to each Marker. That's where the magic lies! See below for an
example. You can follow this pattern to add whatever data you want to
a Marker, and then you can access it in the event handler using
something like:
dataForSelectedMarker : Object = DataBoundMarker(event.target).data
See below for the mechanism for a sample of the extended Marker class.
HTH,
Rick

package mystuff
{
import com.google.maps.overlays.Marker;
import com.google.maps.overlays.MarkerOptions;
import com.google.maps.LatLng;
public class DataBoundMarker extends Marker
{
[Bindable]
public var data : Object;
public function DataBoundMarker(arg0:LatLng,
arg1:MarkerOptions=null, dataRow:Object=null)
{
super(arg0, arg1);
this.data = dataRow;
}
}
}
