This can also usually be accomplished using function closures.
If you use a separate function to create a marker that takes as
parameter(s) the unique data about the marker, and use an anonymous
function for the click event handler defined within the create
function, you will still have access to the parameters that you passed
in.
For example:
private function createMarker(latlng:LatLng, uniqueID:String):Marker {
var marker:Marker = new Marker(latlng, new MarkerOptions({....}));
marker.addEventListener(MapMouseEvent.CLICK, function
(e:MapMouseEvent):void {
trace ("You clicked marker " + uniqueID);
});
return marker;
}
As far as I know you can't explicitly remove an event listener that
uses an anonymous function however, so if you need to remove them at
some point, ie marker is no longer clickable, you probably shouldn't
use this technique. Another thing to remember is that within the
anonymous function the "this" object does not refer to the current
instance of the class that the method belongs to, although the
properties and methods of the instance are still available.
Hope this helps.
