在AS3中最容易实现onReleaseOutside？-EasiestimplementationofonReleaseOutsideinAS3?

Simple and foolproof:

简单而万无一失:

button.addEventListener( MouseEvent.MOUSE_DOWN, mouseDownHandler );
button.addEventListener( MouseEvent.MOUSE_UP, buttonMouseUpHandler ); // *

function mouseDownHandler( event : MouseEvent ) : void {
    trace( "onPress" );
    // this will catch the event anywhere
    event.target.stage.addEventListener( MouseEvent.MOUSE_UP, mouseUpHandler );
}

function buttonMouseUpHandler( event : MouseEvent ) : void {
    trace( "onRelease" );
    // don't bubble up, which would trigger the mouse up on the stage
    event.stopImmediatePropagation( );
}

function mouseUpHandler( event : MouseEvent ) : void {
    trace( "onReleaseOutside" );
    event.target.removeEventListener( MouseEvent.MOUSE_UP, mouseUpHandler );
}

If you don't care about the difference between onRelease and onReleaseOutside (for example with draggable items) you an skip the mouse up listener on the button itself (commented here with an asterisk).

如果您不关心onRelease和onReleaseOutside之间的区别(例如,使用可拖动的项目),您可以跳过按钮本身的鼠标向上监听器(此处用星号表示)。

root.addEventListener(MouseEvent.UP, onMouseReleaseOutside);

You define onMouseReleaseOutside of course. Basically any MouseEvent.UP (a mouse release) that happens outside of your button (or mc) will hit the stage instead of your button. This is the way i usually catch it.

你定义onMouseReleaseOutside当然。基本上任何在按钮(或mc)之外发生的MouseEvent.UP(鼠标释放)都会触发舞台而不是按钮。这是我通常捕捉它的方式。

Have you looked at this event:

你看过这个事件了吗:

flash.events.Event.MOUSE_LEAVE

From the documentation:

从文档:

Dispatched by the Stage object when the mouse pointer moves out of the stage area. The Event.MOUSE_LEAVE constant defines the value of the type property of a mouseLeave event object.

当鼠标指针移出舞台区域时由Stage对象调度。 Event.MOUSE_LEAVE常量定义mouseLeave事件对象的type属性的值。

It will solve your problem if you are only interested whether the user's mouse if off the stage instead of just outside that particular MovieClip.

如果您只关心用户的鼠标是否离开舞台而不是仅仅在特定的MovieClip之外,它将解决您的问题。
