Question

我对flash和as3相对较新。基本上我试图将一个动画片段加载到舞台上，然后单击该动画片段中的一个按钮，从舞台上再次移除该动画片段。我有以下movieclip：

var myResultBox:ResultBox = new ResultBox();
addChild(myResultBox);

我在movieclip中放了一个名为closeButton1的按钮。我试图点击关闭按钮，然后删除动画片段。

MovieClip中的代码是 - //我的结果框中的关闭按钮的事件监听器

closeButton1.addEventListener(MouseEvent.CLICK, closeBMI);

function closeBMI(evt:MouseEvent):void
{
    removeChild(myResultBox);
}

以下错误

代码：1120：访问未定义的属性closeButton1。

非常感谢任何帮助

Answer 1

按钮内？但是你不能以这种方式引用按钮。您应该将代码放在movieclip中，该按钮包含按钮，您可以在其中添加结果addChild(myResultBox);因此，您的事件处理程序将能够引用myResultBox

对于按钮内的代码：

this.addEventListener(MouseEvent.CLICK, closeBMI);

function closeBMI(evt:MouseEvent):void
{
    //removeChild(myResultBox);
    //Sadly, you don't have reference on myResultBox within a button...
}

Answer 2

下面是一个简单的程序，我认为它具有您要求的功能。据我了解，你在舞台上有按钮A.单击按钮A时，影片剪辑B将添加到舞台中。电影剪辑B中有按钮B.单击按钮B时，将删除影片剪辑B和按钮B.

import flash.display.MovieClip;
import flash.display.Sprite;
import flash.events.MouseEvent;


// This creates a movie clip that contains a button.
// This button will remove the movie clip that contains
// it when it is clicked.
var MovieClipB = new MovieClip();
MovieClipB.graphics.lineStyle(1,0);
MovieClipB.graphics.beginFill(0x0000FF,1);
MovieClipB.graphics.drawRect(0,0,50,50);

var ButtonB:MovieClip = new MovieClip();
ButtonB.buttonMode = true;

ButtonB.graphics.lineStyle(1,0);
ButtonB.graphics.beginFill(0xFFFFFF,1)
ButtonB.graphics.drawCircle(0,0,10);
ButtonB.x = ButtonB.y = 25;

MovieClipB.addChild(ButtonB);

ButtonB.addEventListener(MouseEvent.CLICK, removeButtonClickHandler, false, 0, true);
function removeButtonClickHandler(event:MouseEvent):void
{
    var button = MovieClip(event.currentTarget);    
    var container = button.parent;
    container.parent.removeChild(container);
}

// This creates a button that starts on the stage.
// When clicked, it adds the movie clip defined above to the stage

var ButtonA:MovieClip = new MovieClip();
ButtonA.buttonMode = true;

ButtonA.graphics.lineStyle(1,0);
ButtonA.graphics.beginFill(0xFF0000,1)
ButtonA.graphics.drawRect(0,0,50,50);

addChild(ButtonA);
ButtonA.x = ButtonA.y = 20;

ButtonA.addEventListener(MouseEvent.CLICK, addButtonClickHandler, false, 0, true);
function addButtonClickHandler(event:MouseEvent) : void
{
    addChild(MovieClipB);
    MovieClipB.x = 200;
    MovieClipB.y = 20;
}

Movieclip AS3中的按钮不起作用
