accessing a variable in a parent SWF

Hello!

I have an SWF file that loads another SWF file dynamically.

I've managed to make the parent SWF receive a variable from the php page that loads it, via javascript, it works well:

Code:

---

try {
    var keyStr:String;
    var valueStr:String;
    var paramObj:Object = LoaderInfo(this.root.loaderInfo).parameters;
    for (keyStr in paramObj) {
        valueStr = String(paramObj[keyStr]);
            }
} catch (error:Error) {
 }

---

But then I want the nested SWF to access this variable and then do some function.
in this case, the nested swf has a line

Code:

---

cmd:int = -1;

---

the nested swf should be able to receive a number, and pass to a function that would load its respective image from an array. otherwise (if it doesn't receive a number ) it won't do nothing (load no image).

that worked well too, as I tested by manually substituing the number -1 in the statement above with a positive number, inside the flash interface.

Now what should be the simplest part of it (at least in my imagination) is being a pain in the ***.

I've tried using the try/catch statement in the nested SWF like this:

Code:

---

var paramObj:Object = LoaderInfo(MovieClip(parent).loaderInfo).parameters;

---

or

Code:

---

var paramObj:Object = LoaderInfo(parent.loaderInfo).parameters;

---

or trying to access valueStr in the parent SWF file:

Code:

---

MovieClip(parent).valueStr;
and parent.valueStr;

---

but no success.

Please help!
Thanks in advance!

Why wouldn't you include the error messages you're getting?

I'll guess that you are loading the swf with a Loader and it's still a child of that loader. You could add it to the parent swf directly in a complete handler for that loader, or you could use parent.parent. But what you should really do is have a function in the loaded swf that takes the value you want as a parameter. Then call that function from the parent swf when you want to. Or you could have a function that saves a local variable with the value and call that in the complete handler.

Let's say you want to keep a value called "foo". You've retrieved this value in the parent somehow, it doesn't matter for this exercise.

loaded swf has code more or less like this:

Code:

---

var foo:String; //loaded swf's foo variable

function setFoo(f:String):void{
  foo = f;
}

---

and the loading swf has code something like this:

Code:

---


var loader:Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, handleComplete);
loader.load(new URLRequest("myChild.swf"));

function handleComplete(e:Event):void{
  var l:Loader = LoaderInfo(e.currentTarget);
  var clip:MovieClip = MovieClip(l.content);
  clip.setFoo(foo);
}
