Looks like the react version isn't working atm. I'm currently evaluating libraries to use for a quiz build, this work is exciting!

[andrewtelnov]

@tizzo I have fixed the issue. It is working now.

Thank you,
Andrew

I'm currently working on a quiz system based on surveyjs. I'm implementing Right answers like this for the simple cases:

 {
   type: 'radiogroup',
   name: 'SurveyJS is a lot of fun',
   choices: [
     {
       value: 'true',
       text: 'True',
       correct: true,
     },
     {
       value: 'false',
       text: 'False',
     },
   ],
 },

And I'm implementing a simple answer cost and score calculation system. I'm supporting most of the question types provided by surveyJs so there's handling for different question types but in essence I'm doing similar to the following (but with a bunch of different plugin classes that wrap corresponding survyejs question objects).

let correctAnswers = 0;
let totalAnswers = 0;
for (let question of survey.getAllQuestions()) {
  for (let choice of question.activeChoices) {
    if (choice.correct === true) {
      totalAnswers++;
      if (question.value === choice.value) {
        correctAnswers++;
      }
    }
  }
}

I wonder whether you could share more about your roadmap and the architecture for question correctness, grading, providing feedback, etc. Thanks and again I love your work!

Hello @tizzo,
We are working on release v1.0 right now. We are pretty close.
We have the question cost and right answers in our TODO list to finish with Quiz completely, but we have decided to postponed it.
I can't tell your the precise time frame. We may work on it in January, but I can't garantee this.
Anyway, if you have any difficulty of implementing what you want, just let us know and we will help.

Thank you,
Andrew

Thanks @andrewtelnov! Yeah, we need to have something working this week. Would love to find a way to contribute my own answer to this problem but I think it's probably not totally a generalizable solution as I'm building something around SurveyJS rather than into it for this specific use case.

Added:
question.correctAnswer, survey.getCorrectedAnswers(), survey.getInCorrectedAnswers() and the following completedHtml is possible:
"You have answered correctly {correctedAnswers} on {questionCount} questions. {inCorrectedAnswers} answers are incorrect."

Hi,

The ability to do quizzes looks really useful :)

I was looking through the changes and noticed a couple of typos or grammar issues:

• getCorrectedAnswers() should probably be getCorrectAnswers() or perhaps, even better, getCorrectAnswerCount() as the function returns the count and not the actual answers.
• Similarly, getIncorrectedAnswers() should probably be getIncorrectAnswers() or perhaps, even better, getIncorrectAnswerCount().

Hope you don't mind me making these suggestions and that they're helpful. I also noticed a couple of functions on the Page object that looked like they could be tweaked:

• Page.hasShown() to Page.hasBeenShown() or Page.wasShown().
• Page.isQuestionsRandomized() to Page.areQuestionsRandomized()

Cheers,
Simon
