Articulate Storyline: SCORM Reporting from WebObject to LMS

The sample zip file posted here in articulate community contains an example of WebObject sending SCORM variable to LMS. Published output has two javascript files. WebObject uses these two files.

1. story_content/custom.js: This file acts as bridge between Storyline variables and WebObject. WebObject uses custom.js file to communicate with LMS and also to update the Storyline variables on slide for display.
2. webobject/scripts/main.js: WebObject uses main.js for all its internal logics.

var findAPITries = 0;

var lmsAPI;

var gameScore = 0;

function findAPI(win){

while ((win.objLMS == null) && (win.parent != null) && (win.parent != win))

{

findAPITries++;

// Note: 7 is an arbitrary number, but should be more than sufficient

if (findAPITries > 7) 

{

alert("Error finding API -- too deeply nested.");

return null;

}

win = win.parent;

}

return win.objLMS;
