Hi! I need to have a button inside an HTML5 animation (oam) or web object which makes the parent window (Captivate) navigate to the next slide. I've seen this working in Storyline with a button inside an HTML5 object which triggers this javascript function when clicked:

Function next(hypedocument, element, event) {

console.log("go to next");

var player  =  parent.GetPlayer(); /* player */

player.SetVar ("next",Math.floor((Math.random() * 100) + 1));

}

The user needs to navigate an interactive HTML5 animation in a slide before proceeding to the next one, so that's why I need the button inside the web object to tell Captivate to go to the next slide.

Many thanks in advance for your help.
