Question

I want to set an object to null when it’s being clicked and I’m trying to implement this code:

        public function onClick(evt:MouseEvent):void{
        var thisPatient = evt.target;
        thisPatient = null;
    }

However, the element is still on the stage.

Answer 1

public function onClick(evt:MouseEvent):void{
    var thisPatient = evt.target;
    (thisPatient as DisplayObject).parent.removeChild(thisPatient);
    //or if thisPatient is this
    parent.removeChild(this);
}

But it’s bad practive to allow children to remove itself. More right solution is dispathing event because parent must decide remove or not remove child.

public function onClick(evt:MouseEvent):void{
    dispatchEvent(new Event("removeMe", true));
}

//parent's code...
child.addEventListener("removeMe", removeHandler);
