The scope of this

1

Hi
I am just trying to understand the scope of [COLOR=“Blue”]this[/COLOR] in AS3 for example in AS2

basicM_btn.onRelease = function() {
this._visible = false;
}

Would hvae made the button invisible

In AS3 I was expecting to write the same thing as this

function clickHandler(event:MouseEvent):void {

this.visible = false;

}

menuA_btn.addEventListener(MouseEvent.CLICK, clickHandler);

However this sets all of the content on the stage to visible = false

Is there a difference in the way that [COLOR=“blue”]this [/COLOR]works in AS3

Thanks for your help
