当一个国家被悬停时，会发送一个自定义事件，我希望菜单按钮监听该事件，如果传递的参数与其名称相同，则会突出显示该事件。Country类是我的countries movieclips的基类，我在舞台上的嘴唇，MenuButton是menu按钮的基类

这件事似乎永远也办不完

提前感谢

您必须进行两项修改：

首先，将event
bubbles
属性设置为
true
，这样当
Country
剪辑发送事件时，它将上升到顶级

然后，您的
菜单按钮
应该听
阶段
，而不是自己。因此，当一个
国家
发送一个事件时，它会进入
阶段
，并且可以被按钮捕获。如果你想听舞台，你必须对你的代码稍加修改：

public function MenuButton() {

    this.buttonMode = true;
    this.addEventListener(MouseEvent.MOUSE_OVER,onMouseOver);
    this.addEventListener(MouseEvent.MOUSE_OUT, onMouseOut);
    this.addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
}

private function onAddedToStage(e:Event):void 
{
    removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
    stage.addEventListener(CountryEvent.COUNTRY_HOVERED,onCountryOver); 
}
解决此问题的最佳且简单的方法是将stage引用作为类级参数传递，并将事件添加到stage引用，将dispatch事件添加到stage引用

您好，您的不同元素（国家、菜单按钮）是如何添加到舞台上的？他们有相同的父母吗？您可能还想从示例中删除tweens，因为它们独立于您的问题，并降低了问题的可读性。它们不是通过代码添加的，而是世界电影剪辑的一部分。世界，德国，世界，西班牙等等。我会清除代码中不相关的东西。谢谢你！有一个问题，为什么我必须等待添加到舞台的事件？因为如果你不等待，
stage
还不存在。我明白了。。。所以我想对stage进行初始化。Thanx这有助于澄清我头脑中的一些事情，只是为了做一个小小的更正。它的阶段没有初始化。当菜单按钮被添加到舞台上时。在将任何内容添加到其显示列表之前，阶段应该早就初始化了。通过等待添加的_到_阶段触发，我们实际上是在等待许多进程完成。将_添加到_STAGE只是为了确保STAGE是可访问的。
