Hello everyone,

I'm working on a survey where the objective is to record user mouse and gaze patterns.
To do this i'm using some custom js code and webgazer .

To start the recording of mouse and webcam data i put some js code in the question.twig file in a custom theme.

This works but obviously starts one time for every question loaded, so if i have two questions on screen my recording script starts twice and i have data duplication.

Is there someplace else where i could put this code? Maybe with the ability to start it only on certain questions? Can i put js code on specific questions without having to put code in template files?

Yes, why not simply place the code in the source of a question.

Or, if using frequently, place the code in a function in your custom.js file and call that function from within the source of questions.

How do i put code in the source of a question?

When i set "Filter HTML for XSS" to "Off" and then save, the "Filter HTML for XSS" option returns to "On"

Nevermind i did it like 10 times in a row until it took

What LimeSurvey version are you using?

If you are logged in as super-admin, the filter is bypassed anyway.

Version 4.1.7+200224

I got most of my script working but for some reason it seems like the function JSON.stringify does not work when i put in in the source of a question.

Any ideas why? It worked when it was in a twig file and the code is correct, i checked it.

This is the error:

Uncaught SyntaxError: Unexpected token '<'

When using curly braces in question source, you need to insert a space or line-break after the opening brace and before the closing brace to prevent Expression Manager from parsing it.
