JavaScript lib for creating questionnaires?

Question

JavaScript

You need to make a questionnaire (well, there is age, gender, education, favorite color, car, etc., etc.) with scoring. It is clear that riveting on your own is quick, but there are many questions and each next block depends on the results of the previous one. Suddenly there is some suitable one, so as not to fence the bike.
Thanks in advance :)

Answer 1

what about JS?
if each subsequent block of question output depends on the previous one, then this is determined by the server side.
JS is needed if you only check for filling the results.
JQuery, prototype, ExtJs or Dojo,
choose the one we know best

Answer 2

And how serious a questionnaire do you need? How ornate will it be? Is it necessary to save data on the server or is the questionnaire needed only for the convenience of the user (which means that everything can be stored in the browser)?
