Selecting questions based on a custom set of rules was created by Moathh
Please help us help you and fill where relevant:
Your LimeSurvey version: [Version 3.27.6+210629]
Own server or LimeSurvey hosting:
Survey theme/template:
==================I want to create a survey of 192 questions, where each question falls under 3 different categories (i.e. has 3 different attributes). There are 2 classes under the first category, 8 classes in the second category and 20 classes under the third category.I created a js code that draws 20 questions from the 192 according to the following rules:1-Split the questions into two groups based on the first category, Group A and Group B (note: each question in Group A is paired with a question in group B). Now, steps 2-6 applies to questions that belong to Group A2-Randomly select 1 question from each of the 8 classes of the second category (8 questions drawn)3-Determine the third category class for the 8 selected questions in step 2 and exclude all the questions that belong to these 8 classes (out of the 20) from the next draw4-Draw 1 question randomly from the updated set of questions 5-Determine the second category class of the question drawn in 4 and exclude all the questions that belong to this class from the next draw6-Draw 1 question randomly from the updated set of questions. Now we will have a total of 10 questions from Group A7-For each of the 10 questions drawn from Group A, find its matched pair from group B. Now we have a final total of 20 questions8-Schuffle the list of 20 questions and display them
 The code I created does work as intended, however, I am not able to make it work in LimeSurvey so I am not sure what I did wrong and I will appreciate your help. I created a question of type "short text" ("Q0") with the javascript snippet in the question text (source code mode) under Group 0, I put the 192 questions in another group (Group 1) and gave every question of the 192 questions a unique code in the relevance equation (Q1: strpos(Q0,"001")>0, Q2: strpos(Q0,"002")>0, etc.) and gave all questions the same randomization group name.
I attached the test file with the code for your reference.
 Thanks,

Bitte strukturiere den Text ein bisschen besser.

My apologies, the text did not look like this when I posted it. Trying again (hope it works):

I want to create a survey of 192 questions, where each question falls under 3 different categories (i.e. has 3 different attributes). There are 2 classes under the first category, 8 classes in the second category and 20 classes under the third category.I created a js code that draws 20 questions from the 192 according to the following rules:

1-Split the questions into two groups based on the first category, Group A and Group B (note: each question in Group A is paired with a question in group B). Now, steps 2-6 applies to questions that belong to Group A

2-Randomly select 1 question from each of the 8 classes of the second category (8 questions drawn)

3-Determine the third category class for the 8 selected questions in step 2 and exclude all the questions that belong to these 8 classes (out of the 20) from the next draw

4-Draw 1 question randomly from the updated set of questions

5-Determine the second category class of the question drawn in 4 and exclude all the questions that belong to this class from the next draw

6-Draw 1 question randomly from the updated set of questions. Now we will have a total of 10 questions from Group A

7-For each of the 10 questions drawn from Group A, find its matched pair from group B. Now we have a final total of 20 questions

8-Schuffle the list of 20 questions and display them


The code I created does work as intended, however, I am not able to make it work in LimeSurvey so I am not sure what I did wrong and I will appreciate your help.

I created a question of type "short text" ("Q0") with the javascript snippet in the question text (source code mode) under Group 0, I put the 192 questions in another group (Group 1) and gave every question of the 192 questions a unique code in the relevance equation (Q1: strpos(Q0,"001")>0, Q2: strpos(Q0,"002")>0, etc.) and gave all questions the same randomization group name.

As far as I understand, you only want to:
Select 8 questions (1  of each of the 8 classes "ttt")
Select 1 question (the 9.) out of all classes "xn" that does not exist already 
Select 1 question (the 10.) with a "ttt" value different from the 9. question.

Or did I misunderstand completely?

That is exactly what I want to do! In addition, the 192 belong to two different groups, A (96 questions) and B (96 questions). And at the same time, the questions in these two groups are paired (each question in A has a pair in B as indicated by "relID" where a pair have the same "relID").

So, I want to select 10 questions from one of the groups (say Group A) as well as its pair in the other group (Group B), which results in 20 questions.

Finally, I want this set of 20 questions to be displayed randomly, such that the pairs are not displayed in sequence.

Many thanks!!

The question is not being loaded by the JavaScript.

Always check the console.

To start with, you have JavaScript errors because LimeSurvey requires a space after all opening curly braces and before all closing curly braces so they are not parsed by ExpressionScript.

Fix those and retest for other errors.

In the meantime I am working on a a much shorter solution.

The first time I develop javascript by myself.

Let's see.

This would be my JavaScript approach:

1) Shuffle the A array
2) Loop through the 8 "ttt" values in the shuffled array and add the first object found to a new array "questionObjects"
3) Remove those objects from the shuffled array
4) Remove all of the previously selected "xn" values from the shuffled array
5) Find the first object in this newly filtered array and add it to "questionObjects"
6) Remove all objects with the same "ttt" value as above from the shuffled array
7) Again, find the first object in this newly filtered array and add it to "questionObjects"
8) Load the question input with the "id" values from "questionObjects" and with the "id" values from the corresponding (from "relID") objects in the B array
 
 
Code:
<script type="text/javascript" data-author="Tony Partner">  
  $(document).on('ready pjax:scriptcomplete',function(){ 
 
    var questionsArrayA = [
      { "id":"001","ttt":"7","xn":"F4","relID":"1" },
      { "id":"002","ttt":"7","xn":"F4","relID":"2" },
