Javascript error: TypeError: Cannot read property 'contentDocument'

Question

Within the Captivate courses I have a "Web Object" for a JotForms form that the end-user needs to complete before proceeding.

Within Advanced Actions I have:

Conditional Statement - If "cpInfoCurrentFrame" is greater than "30"

Action: Pause

Additionally:

Action: Execute Javascript (Parent)

Javascript&colon;

var iframe = document.getElementById("myFrame_Web_2c");
var innerDoc = iframe.contentDocument || iframe.contentWindow;
var btn = innerDoc.getElementsByClassName("form-submit-button");
btn.addEventListener("click",playCourse);
function playCourse() {
cp.movie.play(cp.ReasonForPlay.PLAYBAR_ACTION);
}

I have received TypeError: Cannot read property 'contentDocument'

when I add a Timeout function I receive var "X" undefined.

Any assistance is greatly appreciated.

Are you trying to test this locally?Without examining your code...Browsers are real finicky about allowing communication through an embedded iFrame as it is considered a security risk.If you publish to a bonafide webserver - the browser should detect that both project and iFrame are a part of the same domain and allow the communication to proceed.
