How To Execute Google Maps Event "bounds_changed" Only Once

How do I tell the google map event 'bounds_change' to only work when the map is initially loaded, and not after user change?

Solution 1:

from the documentation

addListenerOnce(instance:Object, eventName:string, handler:function(?)) Return Value: MapsEventListener Like addListener, but the handler removes itself after handling the first event.

google.maps.event.addListenerOnce(map,'bounds_changed', function() {});
