HTML5/JavaScript (WebObject) Communication with Captivate 9

Hello

Me and my company i work for, trying now for 2 days how that can work... I hope someone can help me or we can do it together

My goal is to have an imported-zipped HTML5 file, with an animation created in Adobe Flash, that can e.g. jump to a next slide. (To keep it simple for now )

What i did so far:

1. I created a HTML5 Canvas in Adobe Flash CC. There i created the animation i want and published it into a HTML5 folder/project.

2. I zipped it and imported it into Captivate, it works pretty fine.

3. I can click on it with a simple EventListener (which i added in Flash) via this.myMovieClip.addEventListener("click", fl_MouseClickHandler.bind(this)); in Captivate. It works nice!

4. Now i wanted to add the possibilty to Click on it and go to next slide through the JavaScript that is created when i publish the Flash file. Since HTML5 and ActionScript3 hasn't the same syntax i am wondering how its is possible...

In AS3 i was able to it through (to access the Captivate:

var myRoot:MovieClip = MovieClip(root);

var mainmov:MovieClip = MovieClip(myRoot.parent.root);

And thats pretty much the problem... I don't know how to let the JavaScript communicate with Captivate when i import the HTML5 Files...

I tried it through "window. ...",  "this.parent. ..." and some other ideas that didn't work.

I have a basic understand of JavaScript, but can't figure it out by myself...

Thx for help. (Or ideas i can try)!!!
