Question

我正在尝试通过在线教程创建手风琴菜单。我按照Original Tutorial的每一步（我认为），但根据我的大小改变了一些事情，并使实例名称以_mc或_txt结尾。但由于某种原因，它似乎没有起作用。

我收到了＃1010错误，并没有真正澄清任何内容：

TypeError：错误＃1010：术语是   未定义且没有属性。
    在   教程_的FLA :: MainTimeline / placeItemsOnStage（）
    在   教程_的FLA :: MainTimeline /的onComplete（）
    在   flash.events::EventDispatcher/dispatchEventFunction（）
    在   flash.events::EventDispatcher/dispatchEvent（）
    在flash.net::URLLoader/onComplete（）

我的第一个xml文件包含要插入的所有图像，而且根本没有更改的图像应该可以正常工作。

我知道这很长，但我希望无论如何都有人可以查看。我对此非常陌生，几乎不得不放弃整个项目。非常感谢！

我的代码：

//import tweenlite classes
import gs.TweenLite;
import gs.easing.*;

var MENU_ARRAY:Array; //used to save the items data
var OPENED_MENU:int; //to inform the menu that should be open at startup
var MOVE_ON_MOUSE_OVER:Boolean=false; //tha name says everything
var xmlLoader:URLLoader; //the xml loader

loadXML("menu2.xml"); //load the xml

function loadXML(Uri:String):void {
   xmlLoader = new URLLoader();
   xmlLoader.addEventListener(Event.COMPLETE, onComplete);
   xmlLoader.addEventListener(IOErrorEvent.IO_ERROR, onError);
   xmlLoader.load(new URLRequest(Uri));
}

function onError(evt:ErrorEvent):void {
   trace("cannot load xml file");
}

function onComplete(evt:Event):void {
   //read and load xml into array, by parsing it using prepareMenu
   MENU_ARRAY=prepareMenu(xmlLoader.data.toString());
   placeItemsOnStage(); //place all required items on stage.
}

}

//finish.
stop();

“term”是指标识符，“错误＃1010：术语未定义且没有属性”表示您正在使用无法计算的表达式。当您尝试通过其myobject["property"].method()中的字符串名称访问和使用未定义的对象属性时，通常会发生这种情况。你能提供引发例外的确切行吗？
