AS3: load external swf's in loop with eventListeners with parametrs

I try to make an app which connect amfphp with as3 animation. i recieve from amfphp an array which i sort by some variable in 'if' statement. after that i've got 2 arrays with arrays inside each other:

var Array1:Array = [["http://url.to.swf", "http://url.to.link"], ["",""]...];
var Array2:Array = [["http://url.to.swf", "http://url.to.link"], ... ];

after that i run a function that read that arrays and load every swf to the stage:

ladujBajkiGorne(Array1);

function ladujBajkiGorne(polkaGorna:Array):void {
    for(var i=0; i<polkaGorna.length; i++) {
        Aktual = polkaGorna[i];
        var mLoader:Loader = new Loader();
        var mRequest:URLRequest = new URLRequest(String(Aktual[0]));
        mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, myfunction = function(e:Event):void { onLoadGorna( e, String(Aktual[1]) ); } );
        mLoader.load(mRequest);
    }
}

then 

function onLoadGorna(e, arg1):void {
   userSwf = e.currentTarget.content;
   userSwf.buttonMode = true;
   userSwf.addEventListener(MouseEvent.CLICK, function(e:MouseEvent) { afterClick(e, arg1 ); });
   booksMC.addChild(userSwf);

   var childName:String = booksMC.getChildAt(childs).name;
   booksMC.getChildByName(childName).x = posX;
   booksMC.getChildByName(childName).y = 0;

   posX += 218;
   childs++;
}

and at the end

function afterClick(e, arg3) {
   var url:URLRequest = new URLRequest(arg3);
   navigateToURL(url, "_self");
}

the problem is that all swf that has been loaded has the same url in the link. it doesn't change in the ladujBajkiGorne function in addEventListener statement. I try many options to change that and nothing works. Any chance to help me with that? Many thanks in advance

The problem is in asynchronous execution of loader complete handler. It would very good to pass appropriate parameter to loader and read it on handler. I propose a simple solution, correcting your code:

function ladujBajkiGorne(polkaGorna:Array):void {
    for(var i=0; i<polkaGorna.length; i++) {
        Aktual = polkaGorna[i];
        var mLoader:Loader = new Loader();
        var mRequest:URLRequest = new URLRequest(Aktual[0]+"?link="+Aktual[1]);
        mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, myfunction = function(e:Event):void { onLoadGorna( e ); } );
        mLoader.load(mRequest);
    }
}

function onLoadGorna(e):void {
   var link:String = e.currentTarget.parameters.link;
   userSwf = e.currentTarget.content;
   userSwf.buttonMode = true;
   userSwf.addEventListener(MouseEvent.CLICK, function(e:MouseEvent) { afterClick(e, link ); });
   booksMC.addChild(userSwf);

   var childName:String = booksMC.getChildAt(childs).name;
   booksMC.getChildByName(childName).x = posX;
   booksMC.getChildByName(childName).y = 0;

   posX += 218;
   childs++;
}

After that every loader knows about its link.

The problem is in the event handler for the complete event. call a function that returns a new function as event handler.

First, Create a function like this:

function getCompleteHandler(url:String):Function {
    return function (e:Event) {
        onLoadGorna(e, url);
    }
}

Then replace this:

mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, myfunction = function(e:Event):void { onLoadGorna( e, String(Aktual[1]) ); } );

By this:

mLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, getCompleteHandler(Aktual[1]) );

That should work now!!
