Parents and Children

Hi Folks,

Now that AS3 is dead, I'm trying to convert all my animations but I was never a good coder to begin with, so here goes.

Many of my animations were a single frame with multiple movies on the frame.  So I might have a button in one movie call (?) another movie to perform some function.  Bad description, but here's what I mean:

nextButton1.addEventListener(MouseEvent.CLICK, toNext1);

function toNext1(event:MouseEvent):void
{
Object(this.parent).overviewText.alpha=0;
Object(this.parent).GovernerLine.gotoAndPlay("On");
Object(this.parent).Filter.gotoAndPlay("Purge");
}

Is there a way to do similar calls in Javascript?

Do I need to rebuild with every single object in the frame and make a very large timeline?

Something in between?

I'm sure I have a steep learning curve ahead.  Suggestions for flattening the curve anyone? 

Thanks!
