子电影中的 URLLoader 处理程序未被调用

您好，我正在编写一个 Flex 应用程序，它有一个 MainMovie，它根据用户在 MainMovie 中选择的内容加载 Flex 程序（ChildMovie）。下面是一些伪代码，希望可以帮助我描述我的问题。

class MainMovie{

  private var request:URLRequest = new URLRequest();

  public function callPHPfile(param:String, loader:URLLoader,   
             handlerFunction:Function):void {

    var parameter:URLVariables=new URLVariables();
    parameter.param = param;
    request.method = URLRequestMethod.POST;
    request.data = parameter;
    request.url = php file on server;
    loader.addEventListener(Event.COMPLETE, handlerFunction);
    loader.load(request);
  }

}

Class ChildMovie {

   private var loaderInChild:URLLoader = new URLLoader();

   public function handlerInChild(e:Event):void {
      process data....
      loaderInChild.removeEventListerner(Event.COMPLETE, handlerInChild);
   }  



   private function buttonClickHandler(e:Event):void{
      Application.application.callPHPfile(param, loaderInChild, handlerInChild)
   }
}

我可以看到 callPHPfile 函数正在执行并从 httpFox 中接收 xml 数据，问题是 handlerInChild 函数中的代码没有被执行。我在这里做错了什么？

Hi I am writing a flex application that has a MainMovie that loads flex programs (ChildMovie) depending on what the user selects in the MainMovie. below is some pseudocode to help me describe my problem hopefully.

class MainMovie{

  private var request:URLRequest = new URLRequest();

  public function callPHPfile(param:String, loader:URLLoader,   
             handlerFunction:Function):void {

    var parameter:URLVariables=new URLVariables();
    parameter.param = param;
    request.method = URLRequestMethod.POST;
    request.data = parameter;
    request.url = php file on server;
    loader.addEventListener(Event.COMPLETE, handlerFunction);
    loader.load(request);
  }

}

Class ChildMovie {

   private var loaderInChild:URLLoader = new URLLoader();

   public function handlerInChild(e:Event):void {
      process data....
      loaderInChild.removeEventListerner(Event.COMPLETE, handlerInChild);
   }  



   private function buttonClickHandler(e:Event):void{
      Application.application.callPHPfile(param, loaderInChild, handlerInChild)
   }
}

I can see that the callPHPfile function is being executed and received xml data from in httpFox, the problem is that the code in the handlerInChild function is not being executed. What am I doing wrong here?

这是一个运行时错误。我忘记了我在 Firefox 中卸载了 Flash Player 调试器，但它没有显示。一行

var data:XML = loader.data;

在 handlerInChild 函数中，应该有

var data:XML = XML(loader.data);

，代码将按预期运行。

It was a runtime error. I forgot that i uninstalled flash player debugger in firefox and it didn't show. in the handlerInChild function, there is a line
