Hi.

When you say "global" I understand you want a variable that is available for all these UI elements, right?

If so, you can write something like this:

HTML5 Canvas:

var result = 0;
function setResult(e)
{
    this.outputText.text = String(++result);
}
this.buttonA.on("click", setResult, this);
this.buttonB.on("click", setResult, this);

AS3:

import flash.events.MouseEvent;
var result:uint = 0;
function setResult(e:MouseEvent):void
{
    outputText.text = String(++result);
}
buttonA.addEventListener(MouseEvent.CLICK, setResult);
buttonB.addEventListener(MouseEvent.CLICK, setResult);

I hope this helps.

Regards,

JC
