Hello everybody, 
I need to understand how I can integrate/activate a JS library into a template; more precisely what I need is that, after making the library work, I can save the data obtained from the library for each question separately.
For example, if I am using a library that saves eye-tracking data and I have 10 questions in the survey, what I'd like to do is save for each question the data telling me where the person that took the survey looked during that question and be able to look at it afterwards. I am struggling because I don't know how to do that... I don't know if I explained good enough (english is not my native language, sorry).
I think that only editing the survey theme and putting the library as a script in the source isn't enough, I may have to edit the question theme separately but right now Lime Survey doesn't allow you to edit the question themes, so what could I do? Download LS from the website and edit the question theme, but then how can I make it possible that someone else could use the integration I made?
I am a bit lost, I don't know how to proceed in general. Thanks in advance to everyone that will answer. 
 

It's not a JS library here : you need a way to save data.

Then : it's a complete plugin system in my opinion.

I didn't understand what you said.
Btw yes, I have to make a plug-in but I don't know how to proceed.

Most JS libraries have events when data is collected. You should be able record the data in the LS inputs when those events are triggered. Details would depend on the API of the library.

Yes : but then : need to create a input on each group to fill the json. Seems complex except if it's a one shot.

I am sorry but I'm really not understanding what you're telling me, could you explain it again?

Again, I'm having troubles understanding what you're telling me. Could you explain to me what you're saying?

Then I don't think you'll be able to implement the solution by yourself anyway, you will need to find someone who understands these explanations.

What Tpartner suggests is have the javascript library to write the collected data from your eye-tracking into a hidden limesurvey question (e.g. a text question that you hide via CSS - NOT via the GUI option "always hide this question").

Oh, I just saw that the user is blocked. What happened?

Sorry, it was me. I realized I explained my problem really bad and I couldn't find a way to delete the post (so that I could re-write it) so I just.. deleted the account(?)
But the post is still there for some reason :<
Anyway you already answered me on the other post I made about this ( forums.limesurvey.org/forum/development/...ed-from-a-js-library ) so thank you here too.
