Ranking question - ranks are set even no changes we performed

[Ticket cloned from T8079: Set score for ranking type of questions]

Hi Andrew,

I discovered a very strange behavior of the survey from the last example you provided. Here is the updated example.

When ranking answers, if you move just 1mm up or down any of the answers and then release, just for them to have a position assigned (not changing their location among answers) at the end of the survey, the questions are repeated again although the answers are ranked.
I created a small video to show this.

Where could the issue be?

Thank you in advance.

Hello,

I believe it's a bug in the ranking question. We'll work on the fix and update this thread as soon as we'll have any results.

Thanks, Serge

Hello,

this behavior is by design feature, not a bug. But maybe we could change it. For now, when you drag ranking item a little bit it changes the indeterminate state of question to determinate. So the question becomes answered with the default items order. And then your areValuesEquals returns true and the quiz restarted.

Could you please describe your scenario in greater detail? Why do you need to restart the quiz when areValuesEquals function returns true?

as a workaround you could use custom validator for example:

JavaScript
survey.onValidateQuestion.add(function(sender, options) {
  const q = options.question;
  const name = q.name;
  const value = q.value;
  const choices = q.visibleChoices;

  if (["Q1", "Q2", "Q3", "Q4"].indexOf(name) === -1) return;

  if(areValuesEquals(choices, value)) {
    options.error = "Please rank the items not in default order";
  }
});

but I am not sure that it is what you are trying to achieve

Thank you,

Hi Dmitry,

Thank you for your reply.
The following functions were created with help from Andrew and their scope is to check if there are any left unanswered questions (user clicked next without ranking any answers) and to repeat those unanswered questions once at the end of the survey.

JavaScript
function areValuesEquals(choices, value) {
    if (!Array.isArray(value)) return false;
 //   debugger;
    for (var i = 0; i < choices.length; i++) {
        if (choices[i].value !== value[i]) return false;
    }
    return true;
}

var surveyRunCount = 0;

function rotate() {
    surveyRunCount++;
    if (surveyRunCount <= 1) {
        const questions = survey.getAllQuestions();
        let hasQuestionsToShow = false;
        for (let i = 0; i < questions.length; i++) {
            const q = questions[i];
            if (survey.firstPageIsStarted && q.page === survey.pages[0]) continue;
            //isEmpty() - was not touched
            if (!q.isEmpty() && !areValuesEquals(q.visibleChoices, q.value)) {
                q.visible = false;
            } else {
                hasQuestionsToShow = true;
            }
        }
        if (hasQuestionsToShow) {
            survey.clear(false, true);
            survey.start();
            return true;
        }
    }
    return false;
}

You're provided workaround is not suitable for my scenario, because:

There might be cases where the user needs to rank the answers in the same default order that was presented to him. With the workaround, the default position of answers can't be used, as the user has to rank differently than default.
The timer keeps running even if the maxTimeToFinishPage was reached. The timer keeps running until the default order is changed.

Please let me know if you need more info regarding this.

Thank you in advance,
Alex.

Hey,

If I understand correctly, you might don't need to run the areValuesEquals function at all. Checking !q.isEmpty () may be sufficient.

If the user just skips the response, q.isEmpty will return true. But if the user drags the element a little without changing the order, the ranking question will set the state and q.isEmpty will return true.

In our opinion, this makes sense. In this case, we assume that the user is happy with the default order of items.
