推荐答案

从 AS3文档：

每当鼠标进入显示对象容器的任何子对象的区域时，即使鼠标已经在显示对象容器的另一个子对象上，mouseOver事件也会被调度。这是与rollOver事件的目的不同的行为，这是为了简化具有子代的显示对象容器的卷展行为的编码。当鼠标从不是其子项之一的对象进入显示对象的区域或其任何子项的区域时，显示对象将调度rollOver事件。 rollOver事件将连续地从对象的父链中分派出来，从最高的父级开始，该父对象既不是相关对象的根目录也不是祖先，并以对象结尾。

The mouseOver event is dispatched each time the mouse enters the area of any child object of the display object container, even if the mouse was already over another child object of the display object container. This is different behavior than the purpose of the rollOver event, which is to simplify the coding of rollout behaviors for display object containers with children. When the mouse enters the area of a display object or the area of any of its children from an object that is not one of its children, the display object dispatches the rollOver event. The rollOver events are dispatched consecutively down the parent chain of the object, starting with the highest parent that is neither the root nor an ancestor of the relatedObject and ending with the object.
