I ask your help with combination of Java Script with Qualtrics. I want to know if such a combination is possible and if the answer is positive, I want to know how to implement this combination.
Are you asking if you can add JavaScript to Qualtrics? The answer is yes. See instructions
here.
Also, below page (Qualtrics JavaScript Question API Class) will be helpful as well:
