Get and load Suspend Data

If your LMS doesn't support SCORM, then there is no way you are going to be able to use the suspend_data, and if you could it would be difficult to parse it's format.

Depending on what information you want to track, you can get custom variables in the cp.ReportingVariables object.

I would also set up a progress array using the slide enter event listener. You can create a "myProgress" variable and store that array in that. Use 1's and 0's to designate visited slides.

You could store that information in your custom LMS or use localStorage. Here is an example I use for the progress in localStorage (HTML5 only):

var nc = document.location.toString();

var netConnected = nc.indexOf( 'http' );

//function to keep track of user's progress. Builds an array 0 = not completed, 1 = completed.
function initProgress()
{
var lessonStorage = cp.model.data.project.pN + '.progressData';  

if ( typeof( Storage ) !== 'undefined' && netConnected != -1 )
{
  if ( localStorage.getItem( lessonStorage ) !== null )
  {  
   var getResults = localStorage.getItem( lessonStorage );           
    myProgress = JSON.parse( getResults );
  }
}
else
{
  for ( var i = 0; i < window.cpInfoSlideCount; i++ )
  {
   myProgress[ i ] = 0;
  }
}
}

function setStorage()
{
var lessonStorage = cp.model.data.project.pN + '.progressData';

if ( typeof( Storage ) !== 'undefined' && netConnected != -1 )
{
  localStorage.setItem( lessonStorage, JSON.stringify( myProgress ) );
}
}
