i make buttons and i give them a unique name , but i can't make function for every one

can any one help ?

here is the code

/////////////////////////////

var xmlLoader:URLLoader = new URLLoader();
var my_Arr:Array= new Array();
var arr_posX:Array =new Array();//= ["350","350","350","350"]
var arr_posY:Array=new Array();//= ["80","120","160","200"]
xmlLoader.addEventListener(Event.COMPLETE, showXML);
xmlLoader.load(new URLRequest("Models.xml"));
function showXML(e:Event):void {
    XML.ignoreWhitespace = true;
    var songs:XML = new XML(e.target.data);
    //trace(songs.track.length());
    var i:Number;
    for (i=0; i < songs.track.length(); i++) {
        var mcArray:Array = new Array();
        var movieClip:MovieClip = new MovieClip();
        addChild(movieClip);
        mcArray = movieClip;
        var dd:String =movieClip.name="my_btn" +i
        my_Arr.push(songs.track.model.text());
        arr_posX.push(songs.track.posX.text());
        arr_posY.push(songs.track.posY.text());
        var outside:MovieClip = new MovieClip();
        movieClip.graphics.beginFill(0xFF0000);
        movieClip.graphics.drawRect(0, 0, 80, 20);
        movieClip.graphics.endFill();
        movieClip.x = arr_posX;
        movieClip.y = arr_posY;
        addChild(movieClip);
        trace(movieClip.name)
        movieClip.buttonMode=true;
                var outputText:TextField = new TextField();
        outputText.x = 5;
        outputText.y = 5;
        //outputText.background = true;
        outputText.autoSize = TextFieldAutoSize.LEFT;
        outputText.text = my_Arr;
        outputText.selectable=false;
        //this.addChild();
        movieClip.addChild(outputText);
        movieClip.addEventListener(MouseEvent.CLICK,go_path);
        function go_path(event:MouseEvent):void {
            trace("aaa");
        }

    }
}

What's this function need to do? Are you referring to 'go_path'?

I would suggest you take this out of your loop and put it at the same level as show_XML. Only have one function to deal with all of the buttons. Once you're inside the function you can deal specifically with whichever button called the function by examining the contents of your MouseEvent object. This contains a property called target, which represents the button that dispatched the CLICK event. From here you can work directly on this property, or if different buttons need to be dealt with differently you can use if/else or switch/case statements to achieve this.

nope. haven't got you.

why can't you give the button a name to identify it?
