Hide column in array question was created by giovbod
Hi Everyone,
I have an array question (let's say 5 rows and 4 columns) and I want to hide one specific column according to the answer to the previous question.
Let's say:
Q1: (multiple coiches) Which column do you want to hide?
Possible answers: A1 = column A, A2 = column B, A3 = column C, A4=column D

I planned to put something like {if(Q1_A1=="Y"} as relevance equation, but I noticed there is no relevance equation for columns in arrays.
What should I do? I saw there is a plugin to hide a column if the label is empty, but it seems in my installation (limesurvey in docker) I cannot access via ssh and therefore I cannot install plugin (unless there is a way from the web interface ...).

Anyone can help me?

Than k you in advance

Assuming that the filter question is on a previous page...

1) In the array answers, insert hidden <span> elements to hold the values of the filter checkboxes:



2) Place this code in the source of the array:

Code:
<script type="text/javascript" data-author="Tony Partner">
  $(document).on('ready pjax:scriptcomplete',function(){
 
    // Identify this question
    var qID = {QID};
    var thisQuestion = $('#question'+qID);
    var thisTable = $('table.subquestion-list:eq(0)', thisQuestion)
 
    $($('.answer-text .filter', thisTable).get().reverse()).each(function(i) {
      var thisIndex = $(this).closest('th').index();
      var filter = $.trim($(this).text());
      if($('span[id^="LEMtailor"]', this).length > 0) {
        filter = $.trim($('span[id^="LEMtailor"]', this).text())
      }
      if(filter == 'Y') {
        hideColumn(thisIndex)
      }
    });
 
    function hideColumn(index) {
      $('col:nth-child('+(index+1)+'), thead .answer-text:nth-child('+(index+1)+'), tr.answers-list .answer-item:nth-child('+(index+1)+')', thisTable).hide();
      $('tr.answers-list .answer-item:nth-child('+(index+1)+') :radio:checked', thisTable).each(function(i) {
        $(this).prop('checked', false);
        checkconditions('', $(this).attr('name'), $(this).attr('type'));
      });
    }
  });
</script>

Thanks a lot for the code!
It works great, but only for normal arrays. Could the same be achieved for Numbers arrays?

Please have a look at the plugin "hideEmptyColumn".
[url] gitlab.com/SondagesPro/QuestionSettingsType/hideEmptyColumn [/url]
Demo survey is included.

For anyone that isn't allowed to install plugins on their limesurvey instance, this works for me on numbered array:
Code:
<script type="text/javascript">
    $(document).on('ready pjax:scriptcomplete',function(){
 
        // Identify this question
        var qID = {QID};
        var thisQuestion = $('#question'+qID);
        var thisTable = $('table.subquestion-list:eq(0)', thisQuestion)
 
        $($('.ls-heading .filter', thisTable).get().reverse()).each(function(i) {
            var lineRead = $($('.ls-heading .filter', thisTable).get().reverse());
            var thisIndex = $(this).closest('th').index();
            var filter = $.trim($(this).text());
            if($('span[id^="LEMtailor"]', this).length > 0) {
                filter = $.trim($('span[id^="LEMtailor"]', this).text())
            }
            if(filter == 'Y') {
                hideColumn(thisIndex)
            }
        });
 
        function hideColumn(index) {
            $('td.answer-item:nth-child('+(index+1)+')', thisTable).hide();
            $('th.answertext:nth-child('+(index+1)+')', thisTable).hide();
            $('tr.ls-heading th:nth-child('+(index+1)+')', thisTable).hide();
            $('col:nth-child('+(index+1)+')', thisTable).hide();
        }
    });
</script>

This is just a slight modification of the code previously posted here for normal arrays. So the procedure is the same.
My javascript skills are pretty awful, be sure to test thoroughly before deploying this.

The scripts for array questions from TPartner as well as the adapted one for array (numbers) from tenroc worked fine for version 5.3.26. As of yesterday with the update to 5.3.27 they are not working anymore. (With 3.25.9 all good too)

The same goes for Joffm's method in his array workaround tutorial (it's super helpful btw:https://forums.limesurvey.org/forum/german-forum/125239-joffms-tutorial-1-matrizen-stand-27-10-2021)
His method (chapter 14) was working fine, aso of yesterday with V 5.3.27 it's not.

Any ideas?

The problem is that for some reason the HTML structure of the array table was changed.

In the meantime while I lobby for reverting the "fix", this will work for arrays.

Code:
<script type="text/javascript" data-author="Tony Partner">
  $(document).on('ready pjax:scriptcomplete',function(){
 
    // Identify this question
    var qID = {QID};
    var thisQuestion = $('#question'+qID);
    var thisTable = $('table.subquestion-list:eq(0)', thisQuestion)
 
    $($('.answer-text .filter', thisTable).get().reverse()).each(function(i) {
      var thisIndex = $(this).closest('.answer-text').index();
      var filter = $.trim($(this).text());
      if($('span[id^="LEMtailor"]', this).length > 0) {
        filter = $.trim($('span[id^="LEMtailor"]', this).text())
      }
      if(filter == 'Y') {
        hideColumn(thisIndex)
      }
    });
 
    function hideColumn(index) {
      $('col:nth-child('+(index+1)+'), .ls-heading .answer-text:nth-child('+(index+1)+'), tr.answers-list .answer-item:nth-child('+(index+1)+')', thisTable).hide();
      $('tr.answers-list .answer-item:nth-child('+(index+1)+') :radio:checked', thisTable).each(function(i) {
        $(this).prop('checked', false);
        checkconditions('', $(this).attr('name'), $(this).attr('type'));
      });
    }
  });
 
</script>

Again big thank you tpartner for your efforts.
I should have noted the change in the table header elements (as of update to 5.3.27).

The adapted script works fine!
Let's see if I have to change back soon if the "fix" is reverted -> This is a reminder for everyone that the script in #230625 might be irrelevant again soon.

This will work if the "fix" is reverted.
