最好的做法是使用事件，以确保您的类是不是太紧密耦合。下面是做这件事，但当然有很多不同的方法可用....

Best practice is to use events so as to ensure that your Classes are not too tightly coupled. Here's one way to do it but there are of course many different approaches available....

   //In your main class
   private var dispatcher:EventDispatcher = new EventDispatcher();

   private var page1:A; 
   private var page2:B; 

   public function Main()
   {
      page1 = new A( dispatcher );
      page2 = new B( dispatcher );
   }


   //In Class A ( or Class B )
   private var dispatcher:EventDispatcher;

   public function A( dispatcher:EventDispatcher )
   {
        this.dispatcher = dispatcher;
        dispatcher.addEventListener( CustomEvent.EXAMPLE , customEventListener );
   }

   private function customEventListener( event:CustomEvent ):void
   {
       trace( event.type  , event.data );
   }

   private function anyMethod(data:Object):void
   {
       //using a CustomEvent with a data property
       //also passing a type can help in selecting between actions
       dispatcher.dispatchEvent( new CustomEvent( CustomEvent.EXAMPLE ,  data ) );
   }
