Answer 1

function OPTIONbtn(e:MouseEvent):void 
{
    ///...
    optionBOX.ok_btn.addEventListener(MouseEvent.CLICK, OKbtn);
}

function OKbtn(e:MouseEvent):void 
{
    trace("my ok button");
}

或者

function OPTIONbtn(e:MouseEvent):void 
{
    ///...
    optionBOX.ok_btn.addEventListener(MouseEvent.CLICK, function OKbtn(e:MouseEvent):void 
    {
        trace("my ok button");
    });
}
