Question

我的代码存在问题，因此我有一个衍生的垂直动画片段，其中有按钮实例，使其看起来像一个列表。

问题是我正在尝试重新创建iOS风格的拖动滚动。当我按住并拖动我的movieclip时，它工作正常，上下滚动。但是当我释放鼠标左键时，它会在我的一个按钮上注册一次。

我尝试删除按钮上的事件侦听器，但滚动只能工作一次，在我释放鼠标左键后，整个滚动操作第二次不起作用。

是否有可能像鼠标拖动（向上或向下）忽略按钮单击侦听器，但是当用户想要单击按钮时，滚动不会启动？

我的按钮＆＃39;类

public function PlaceOneButtons()
    {
            for (var a=0; a<buttons.length; a++)
            {
                stationsone1[a].addEventListener(clicked,StationSelectOne);
                stationsone2[a].addEventListener(clicked,StationSelectOne);
                stationsone3[a].addEventListener(clicked,StationSelectOne);
                stationsone4[a].addEventListener(clicked,StationSelectOne);
                stationsone5[a].addEventListener(clicked,StationSelectOne);
            }

    }

帮助将不胜感激！几天来一直坚持这个问题。

更新：添加了新的更新代码

大家好，我现在的问题是，在滚动动画片段之后，如果它的= 0，代码会侦听scrollDiff。

当scrollDiff为0时，动画片段的按钮是可点击的，但如果它多于或少于该按钮，则按钮不可点击。现在我的新问题是，在我释放左键后，代码不会将scrollDiff更新为0，因此用户必须双击才能选择按钮。救命啊！

Answer 1

当你移动集<container_mc>.mouseChildren = false时。当容器剪辑停止移动时，将mouseChildren属性设置为“true”。

Answer 2

添加到Craig的答案（我绝对建议实现，以使生活更轻松！），这里是您应该为此按计划工作的事件监听器列表。这是理论，所以你可能不得不玩一下。

container.addEventListener(MouseEvent.MOUSE_DOWN, response);：你想要提出一些鼠标停止的标志，并等待下一个鼠标事件，这决定了行动。

container.addEventListener(MouseEvent.MOUSE_MOVE, response);：如果鼠标已关闭，请禁用子项单击（Craig的答案）并开始拖动。你还想提出拖拽标志。

container.addEventListener(MouseEvent.MOUSE_UP, response);：如果引发拖动标记，请停止拖动并启用子项单击。如果它没有被提升，则什么也不做，所以该项目可以从那里接管。

item.addEventListener(MouseEvent.MOUSE_UP, itemResponse);：您的点击操作。

理论上，只要你使用MouseEvent.MOUSE_UP作为它们的监听器（如上所示），这应该适用于嵌套的MovieClip。使用MouseEvent.MOUSE_DOWN或MouseEvent.CLICK可能会弄乱您的计时。但是，我会进行一些实验来找到正确的组合，因为在最后一点我可能错了。
