调用函数时出错属性 AS3

Question

C:...\HandleXML.as, Line 28 1120: Access of undefined property processXML.

为什么？...这不是我的文档 class，但其中没有调用此 class 的内容。当我把它放在我的文档 class 中时它起作用了，但我试图将文档 class 分成多个 classes。无论我读什么，拥有多个 classes 对我来说仍然很奇怪。

package  {

    import flash.events.Event;
    import flash.events.MouseEvent;
    import flash.events.KeyboardEvent;
    import flash.xml.*;

            saveXML = new XML(xmlOutput);
        }

        {
            var tempArray:Array = new Array();
            var tempStr:String = mapXML.ROW.toString();

            tempStr = tempStr.replace(/<ROW>/g, "");
            tempStr = tempStr.replace(/<\/ROW>/g, "");

            tempArray.push(tempStr.split(","));

            for(var i:int = 0; i < mapXML.MapHeight; i++)
            {
                Engine.mapArray[i] = [];

                for(var j:int = 0; j < mapXML.MapWidth; j++)
                {
                    Engine.mapArray[i].push(tempArray[0].shift());
                }
            }
        }
    }
}

正如您所指出的，UseGeneric 函数在不应该声明为静态时被声明为：

public function UseGeneric()
{
    var myLoader:URLLoader = new URLLoader();
    myLoader.load(new URLRequest("Maps/TestMap.xml"));
    myLoader.addEventListener(Event.COMPLETE, processXML);
}
