Question

C：... \ HandleXML.as，第28行1120：访问未定义的属性processXML。

为什么？...这不是我的Document类，但是在这个类中没有任何调用。它在我的文档课中有用，但是我试图将文档类分成多个类。无论我读什么，有多个课程对我来说仍然很奇怪。

正如您所指出的那样，UseGeneric函数在不应该被声明为静态时为：

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

错误是将函数调用为属性AS3
