Actionscript 3 当动态滚动文本到达底部时，是否可以调用Flash（AS3）功能？

希望在用户在Flash AS3中滚动到动态文本框底部后执行动画。文本是动态加载的，如果这很重要的话。

像这样的东西应该可以做到：

        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
            }
        }
