package {
    import flash.display.MovieClip;
    import DemoClass;
    
    
    public class Main extends MovieClip  {
        
        protected var demo:DemoClass = new DemoClass();    
        
        public function Main() {
           demo.setData(result);    
        }        
        
        public function  result():void {
             trace("我就是回调函数！")
        }
        
    }
}

下来是我们的另一个文件:DemoClass.as

package {    
    
    import flash.display.MovieClip
    
    public class DemoClass extends MovieClip {
        
        protected var m_onFun:Function;
        
        public function DemoClass() {
            
        }
        
        public function setData(onFun:Function):void {
            onFun();
        }
        
        public function onClick():void {
            
        }
    }
}
