Set score for ranking type of questions

Hi Serge,

Thank you for your reply. I have seen this example and I don't think it will work for me. The example sets a specific score for all the answers in a question.
After reviewing it, I realized that a more suitable solution for me would be to use "weights" for my questions, to give specific "weights" to answers.
What I need is that when answers are ranked, the order they are in, will give each one a value or "weight". The first position gives the highest “weight” - 5 and it goes down in value until the last position, which gives the lowest “weight” - 1. In a question with 5 choices, when an item is ranked number one, it gets a value of 5, second position gets a value of 4, the fifth position gets the lowest score of 1.
Also these "weights" have to be shown at the and of the survey with the rest of the normal JSON output.

I think that I should use something like this:

Java
Survey.Serializer.addProperty("question", {name: "!weight:number", default: 0});

Can you please provide an example for something like this?

Thank you in advance.

Hello,

As far as I understand you need to implement custom scoring function.

The sample I've provided earlier contains the score calculation fragment:

JavaScript
survey
    .onComplete
    .add(function (survey) {
       var totalScore = 0;
       var data = survey.data;

       Object.keys(data).forEach(function(qName) {
          var question = survey.getQuestionByName(qName);
          var qValue = data[qName];

          if (question.choices) {
            question.choices.forEach(function(choice) {
              if (choice.value === qValue) {
                totalScore += choice.score;
              }
              if (question.getType() !== "ranking" && Array.isArray(qValue) && qValue.indexOf(choice.value) !== -1) {
                totalScore += choice.score;
              }
              if (question.getType() === "ranking" && Array.isArray(qValue) && qValue.indexOf(choice.value) !== -1) {
                // Or implement your own algorithm for ranking question scoring
                totalScore += choice.score;
              }
            });
          } else {
            totalScore += question.score;
          }

        });

        document
            .querySelector('#surveyResult')
            .innerHTML = "total score: " + JSON.stringify(totalScore);
    });

You can modify it according your requirements. It's an ordinary task for a JavaScript programmer.
Unfortunately we don't provide custom programming services.

Hello Alex,
I am not sure that I understood your task correctly. Here is the example that works as I understand the task.

Hi Andrew,

Unfortunately, the example you sent is not the survey behavior I'm looking for. :(

What I'm looking to achieve is that, in a ranking question, when answers are ranked, the order they are ranked in, will give each answer a value or "weight". The first ranked position gives the highest “weight” - 5 and it goes down in value until the last position, which gives the lowest “weight” - 1.
I'm looking to add a value to the ranked positions.
In a question with 5 choices, when an item is ranked number one, it gets a value of 5, second position gets a value of 4 ans so on, third position gets a value of 3, and so on until the fifth position gets the lowest score of 1.

Also these "weights" have to be shown at the and of the survey with the rest of the normal JSON output, something like this:
Result JSON: { "q1": [ "item5", "weight: 5", "item1", "weight: 4", "item2", "weight: 3", "item3", "weight: 2", "item4", "weight: 1"], "q2": [ item3", "weight: 5", "item1", "weight: 4", "item2", "weight: 3", "item5", "weight: 2", "item4", "weight: 1"], "q3": [ "item4", "weight: 5", "item1", "weight: 4", "item2", "weight: 3", "item3", "weight: 2", "item5", "weight: 1"] }

I hope this is more understandable now.

Thank you very much.

In this case, you don't need any new property at all.
Here is the example.

Hi Andrew,

Thank you very much for your help. It works like a charm.

Now, I combined your example with the previous entire script and when I rank all questions and complete the survey I get the end survey JSON result perfectly.
If I skip one question (leave it unranked), the result JSON is displayed incomplete during the survey run and complete at the end.

Here is an example.

What am I doing wrong?

Thank you.

Hello Alex,
You have to do it in one event handler, otherwise your return from function in the first onComplete event doesn't work, since the second function for complete event is executed. Here is the updated example.
