Question

我一直在尝试动态添加按钮，然后为它们分配事件侦听器。我的代码是，

    var i=0;
    var step=50;
    for each (var child:XML in courseXML.footer.tray.elements())
    {           
        var thumbClip:thumb = new thumb();
        //set name 
        thumbClip.name = "mc_thumb" + (i + 1);
        trace("thumbClipname:: "+thumbClip.name);
        //set the x and y values
        thumbClip.x = 620 + (i * step);
        thumbClip.y = 560;

        //attach the newly created instance to the container
        addChild(thumbClip);
        trace("thumbClip:: "+thumbClip);

        //attach icon image from xml path
        thumbClip.thumbLoader.source = child.icon;
        trace("thumbClip.thumbLoader.source: "+thumbClip.thumbLoader.source);

        //add listeners
        trace("Node name "+ child.localName());
        if(child.localName().toLowerCase() == "feedback");
        {   trace("gotoFeedback..");
            thumbClip.addEventListener(MouseEvent.CLICK, gotoFeedback);
        }
        if(child.localName().toLowerCase() == "resources");
        {   trace("gotoResources..");
            thumbClip.addEventListener(MouseEvent.CLICK, gotoResources);
        }
        if(child.localName().toLowerCase() == "glossary");
        {   trace("gotoGlossary..");
            thumbClip.addEventListener(MouseEvent.CLICK, gotoGlossary);
        }
        if(child.localName().toLowerCase() == "discussion");
        {   trace("gotoDiscussion..");
            thumbClip.addEventListener(MouseEvent.CLICK, gotoDiscussion);
        }

        thumbClip.buttonMode = true;
        i++;
    }

所以，最后在舞台上显示了4个按钮，当我点击任何按钮时，所有四个函数gotofeedback, gotoResources, gotoGlossary, gotoDiscussion都会被调用。如何在按钮点击时调用相应的功能？谢谢！

The four functions are:
function gotoFeedback(e: MouseEvent):void
{
    trace("gotofeedback fn called..");
}
function gotoResources(e: MouseEvent):void
{
    trace("gotoResources fn called..");
}
function gotoGlossary(e: MouseEvent):void
{
    trace("gotoGlossary fn called..");
}
function gotoDiscussion(e: MouseEvent):void
{
    trace("gotoDiscussion fn called..");
}

您需要将事件侦听器添加到子按钮，而不是添加到thumbClip。你现在拥有代码的方式，只要在thumbClip内的任何地方点击鼠标，就会调用所有的监听器（这就是你所看到的）。

动作脚本：单击按钮调用相应的功能
