Call javascript trigger to commit or setValue in Scorm 1.2

Hi guys,

I tried to set a javascript trigger to set a value and commit it afterwards (my scorm API does not send after each setValue).

I added a javascript trigger to a next button and wanted to trigger each time it is pressed. This works but when excecuting my method it fails because the referenced objects or methods are not defined (I can see this in the browsers debug console). The Project is exported as html5.

I tried

LMSSetValue("screen", "Screen 1");

and

LMSCommit("");

 

And also

API.LMSSetValue("screen", "Screen 1");

API.LMSCommit(""); -> where API is my global custom LMS interface

 

What is the correct way to call the LMS methods from javascript triggers?

My goal is to send the slide number on button press to a custom LMS which is based on scorm 1.2, but does not support the complete scorm 1.2 standard.

Is the slide number saved in a player variable which I'm able to query?

Any ideas? Thanks for your help, best Astrid
