Flash - create functions in loop

Hey guys,

I have the following code, which is not so pleasant to work with...
function ButtonOneOut(e:MouseEvent){
	btnOutFunction(e);
}
function ButtonTwoOut(e:MouseEvent) {
	btnOutFunction(e);
}
function ButtonThreeOut(e:MouseEvent) {
	btnOutFunction(e);
}
function ButtonFourOut(e:MouseEvent) {
	btnOutFunction(e);
}
function ButtonFiveOut(e:MouseEvent) {
	btnOutFunction(e);
}
function ButtonSixOut(e:MouseEvent) {
	btnOutFunction(e);
}

Open in new window


So to avoid this, how can I create multiple functions in a loop?
I've got this array already
var buttons:Array = ["ButtonOne","ButtonTwo","ButtonThree","ButtonFour","ButtonFive","ButtonSix"];

Open in new window

It would help me a lot :)

It looks like you have added event listener's to all 6 buttons, and for all handlers you want to call the same function.

I am assuming all these buttons are in one parent.
So here you go:
=====================
function addListeners():void
{
  var parent:DisplayObjectContainer = this as DisplayObjectContainer; //here you can replace "this" with the parent.

  // I am assuming all this buttons are sprite, or needed you can typecast it with whatever type you have
  var target:Sprite;
  for (var btnIdx:int = 0; btnIdx < buttons.length; btnIdx++)
  {
    target = parent.getChildByName(buttons[btnIdx]) as Sprite; // you can use other type as per need instead of sprite
    target.addEventListener(MouseEvent.MouseOut, mouseOutHandler);
  }
}

function mouseOutHandler(e:MouseEvent):void
{
  btnOutFunction(e);
}

Let me know your finding.
