Get variables from iframe in Javascript

Hi! 

I created a custom variable "isStorylineCompleted" in Storyline that is set to "true" when the last slide is viewed. And in my parent window, I would like to show a button if the last slide is viewed.

My Storyline is embedded in an iframe and I would like to get the value of this variable "isStorylineCompleted" in the parent view in javascript.

I am a developper but I do not use the Storyline software myself.

Thank you so much for the help :-)

    if the LMS and the course in the iFrame are in the same domain*, it's easy

    javascript trigger in Storyline

    const player = GetPlayer();
    const completed = player.GetVar("isStorylineCompleted");

    if(parent && parent.setCourseState){
      parent.setCourseState( completed );
    }

    javascript in the outer html

    <script>
      function setCourseState( inState ){
        alert( "course state: " + inState );
      }
    </script>

    * if not use postMessage
