get learner's details from LMS

Hello,

I’m trying to get the learner’s details from the LMS, using java script.

I used the following code:

var player = GetPlayer();

function findLMSAPI(win) {

  if (win.hasOwnProperty("GetStudentID")) return win;

  else if (win.parent == win) return null;

  else return findLMSAPI(win.parent);

}

var lmsAPI = findLMSAPI(this);

// *** The following code is working ***

var myName = lmsAPI.GetStudentName();

var myID =  lmsAPI.GetStudentID();

 

// *** The following code is NOT working ***

var myChunk = lmsAPI.GetDataChunk();

var myLaunchData = lmsAPI.GetLaunchData();

var myLNG = lmsAPI.GetLanguagePreference();

The functions reference appears in the link below:

for some reason, the learner’s name and ID was passed successfully, but all 3 other functions did not.

Does anyone know how to solve this?

Thank you.
