从Class函数中停止主时间轴-StopthemaintimelinefromwithinaClassfunction

You can access the main timeline from any display object (that is on the display list) by using the root keyword:

您可以使用root关键字从任何显示对象(位于显示列表中)访问主时间轴:

MovieClip(root).stop();

If your class is not on the display list (as appears to be your case), then you'll need to pass in a reference to something that is. I see you are passing in a stage reference, so you could use that:

如果您的班级不在显示列表中(看起来像您的情况),那么您需要传入对某些内容的引用。我看到你正在传递一个阶段参考,所以你可以使用它:

MovieClip(stage.getChildAt(0)).stop();

The main timeline (unless you've manually added something else to the stage at position 0) will be the first child of the stage.

主时间轴(除非你手动将其他东西添加到位置0的舞台上)将是舞台的第一个孩子。

So you code would then look like this:

所以你的代码看起来像这样:

public function myApplication(stageRoot:Stage) {
   MovieClip(stageRoot.getChildAt(0)).stop();
}

OR, if based off your comments you just pass root timeline in:

或者,如果基于您的评论,您只需传递根时间轴:

public function myApplication(timelineRoot:MovieClip){
    timelineRoot.stop();

    //stage can be had by doing:  timelineRoot.stage
}
