Ability to provide secure question hints about survey-library HOT 2 CLOSED

Hi,

I understand what you are trying to implement here.

If you would not worry about showing survey json, then you would have something like that:
Question N: Question title and a radio group: (hard) – (easy).
Question N (hard): visible by default. It may not have a title and it has question.indent > 0
Question N (easy): invisible by default and it has question.indent > 0

Using “setValue” trigger (http://surveyjs.org/examples/trigger-setvalue.html) , you may set an invisible question value that a student actually look at the easy question. Another way is to hide Question N and Question N (hard) completely on choosing (“easy”) and make the easy question visible, so a student will not be able to return to the hard question and use a tip(s) to answer it.

So, now the question to you :-). If you would get the full json from the server, then surveyjs will built the survey based on the json metadata and json will be disappeared. Do you concern that your student may intercept the json when it passed from the server?

About “Quiz” – I am thinking to add this functionality directly into surveyjs and dxsurvey.com.
For example, currently I have an idea to pass encrypted corrected answers to a client. However, a client (surveyjs lib) will not able to decrypt the answer, there will be the ability to check, if the answer correct or not, by encrypting the given answer and compare the result with the encrypted correct answer.
If you have any requirements, I would be happy to learn them.

Thank you,

@andrewtelnov what's to stop someone form running the compare code from the console on each of the choices?

I think this is something that has to be done server side.

P.S. "Quiz" is not a requirement for me.
