问题描述

我想创建一个卷轴...的videoSlider是我的滚动条，我想将它拖到所以我secondMC将移动....一切工作正常，在我的code，但如果我按下鼠标在我的videoSlider最多在它之外....拖动状态仍然适用，这不是我想要....任何想法？谢谢...

  videoSlider.addEventListener（的MouseEvent.MOUSE_DOWN，scrollMC）;
        videoSlider.addEventListener（侦听MouseEvent.MOUSE_UP，stopScrollMC）;



VAR的eventTarget：对象; //允许拖动的对象更多的全球访问

    功能scrollMC（事件：MouseEvent）方法：无效{
          的eventTarget =对象（event.currentTarget）;
          eventTarget.startDrag（假，新的Rectangle（0,0,500,0））;
          stage.addEventListener（的MouseEvent.MOUSE_MOVE，adjust2ndX）;
    }

    功能stopScrollMC（事件：MouseEvent）方法：无效{
          eventTarget.stopDrag（）;
          stage.removeEventListener（的MouseEvent.MOUSE_MOVE，adjust2ndX）;
    }

    功能adjust2ndX（EVT：MouseEvent）方法：无效{
          secondMC.x = eventTarget.x;
    }
 

解决方案

监听的MouseUp在舞台上。你的目标是不会，如果鼠标松开发生在其他地方获得一个MouseUp事件。

I am trying to create a scroller...The videoSlider is my scrollBar and I want to drag it so my secondMC will move....everything works fine in my code but if I mouse down in my videoSlider and up outside of it....The drag state still apply and it's not what I desire....any ideas?? Thanks...

      videoSlider.addEventListener(MouseEvent.MOUSE_DOWN, scrollMC);
        videoSlider.addEventListener(MouseEvent.MOUSE_UP, stopScrollMC);



var eventTarget:Object; // to allow more global access to the dragged object

    function scrollMC(event:MouseEvent):void{
          eventTarget = Object(event.currentTarget);
          eventTarget.startDrag(false,new Rectangle(0,0,500,0));
          stage.addEventListener(MouseEvent.MOUSE_MOVE, adjust2ndX);
    }

    function stopScrollMC(event:MouseEvent):void{
          eventTarget.stopDrag();
          stage.removeEventListener(MouseEvent.MOUSE_MOVE, adjust2ndX);
    }

    function adjust2ndX(evt:MouseEvent):void {
          secondMC.x = eventTarget.x; 
    }

解决方案

Listen for MouseUp on the stage. Your object isn't going to get a MouseUp event if the mouseup occurs somewhere else.
