动态滚动文本到底时可以调用Flash（AS3）函数吗？

Question

想要在用户滚动到Flash AS3中动态文本框的底部之后执行动画。文本是动态加载的，如果有的话。

Answer 1

像这样的东西应该做的伎俩：

 myTextField.addEventListener(Event.SCROLL, scrollHandler); 

     function scrollHandler(e:Event):void { 
      if (myTextField.scrollV >= myTextField.maxScrollV) { 
       trace("You've Reached The End - It happens to us all eventually"); 
       //do your animation 
      } 
     }

我搜索，在我的项目最后部署。这是工作代码。非常感谢你为我提供大部分解决方案。
