AS3：访问外部加载的 swf 文件的函数时出错

Question

I get the following error:

Error #1069: Property externalFun not found on LoadedFile and there is no default value.

My main project file:

        questionLoader = new Loader();
        var questionRequest:URLRequest = new URLRequest(xmlName);
        questionLoader.load(questionRequest);
        questionLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, swfLoaded);

 public function swfLoaded(e:Event) {

        var target: MovieClip = e.currentTarget.content;
        trace(target);

        addChild(target);
        target.externalFun();
    }

Loaded swf:

   public function LoadedFile() {
        // constructor code

        this.addEventListener(Event.ADDED_TO_STAGE,init);

    }

    public function externalFun():void {

    trace("IT WORKS");

    }

Any ideas?

Answer 1

Listen to Event.INIT rather than Event.COMPLETE . Event.COMPLETE happens immediately after all bytes are loaded and does not indicate that loaded content is actually available already. If you care to put one trace before calling externalFun and the other into the LoadedFile constructor, the latter one will fire later than the former. However, Event.INIT occurs after the loaded content is initialized thus the problem probably will go away. If no, proceed with trace diagnostics described above and probably wait 1 frame after Event.INIT fires before calling the function you want.
