LimeSurvey version?

I'm not in a position to debug this weekend but can you give us a link to a live test survey?

Cheers,
Tony Partner

I ask again, what LimeSurvey version?

That appears to be a link to the LimeSurvey admin section, not the survey.

Hi, Rita,
looking at your survey I see something like the default template of LS version 2.05/2.06.
But you say you work with version 2.50.

You know that the "old" templates don't work correctly in 2.50.
On the other side I fear that the example which was created and tested with version 1.87 will not work in newer versions, especially 2.50

Please, provide a sample survey with just this question (*.lss).

Best regards
Joffm

If using version 2.50, follow these steps to create a MaxDiff question type:

1) Set up your survey to use JavaScript .

2) Create an Array (flexible labels) by column question with 2 "answers" - these will be the left and right columns.

3) Create a copy the default template.

4) Add the following to the end of template.js in your new template:
Code:
function maxDiff(qID, randomize) {
 
  // Identify some elements
  var thisQuestion = $('#question'+qID);
  var thisTable = $('table.subquestion-list:eq(0)', thisQuestion);
 
  // Assign a new question class
  $(thisQuestion).addClass('max-diff-array');
 
  // Move the columns
  $('thead tr:eq(0) th:eq(1)', thisTable).prependTo('thead tr:eq(0)', thisTable);
  $('tr.answers-list', thisTable).each(function(i){
    $('td.answer-item:eq(0)', this).prependTo(this);
  });
 
  // Random rows
  if(randomize) {
    var rowsArr = [];
    $('tr.answers-list', thisTable).each(function(i){
      $(this).attr('data-index', i);
      rowsArr.push(i);
    });
    shuffleArray(rowsArr);
    $(rowsArr).each(function(i){
      $('tbody', thisTable).append($('tr[data-index="'+this+'"]', thisTable));
    });
  }
 
  // Prevent clicking twice in the same row
  $('input.radio', thisQuestion).on('click', function () {
 
    $('input.radio', thisQuestion).prop('disabled', false);
    $('input.radio:checked', thisQuestion).each(function(i) {
      var thisRow = $(this).closest('tr.answers-list');
      $('input.radio', thisRow).not(this).prop('disabled', true);
    });
  });  
 
  // Fix up the row classes
  var rowClass = 1;
  $('tr.answers-list', thisTable).each(function(i) {
    $(this).addClass('array'+(2-(i%2)));
  });
}
 
function shuffleArray(array) {
  for (var i = array.length - 1; i > 0; i--) {
    var j = Math.floor(Math.random() * (i + 1));
    var temp = array[i];
    array[i] = array[j];
    array[j] = temp;
  }
  return array;
}

5) Add something like the following to the end of template.css in your new template:
Code:
.max-diff-array th.answertext { 
  text-align: center;
  border-right: 3px solid #FFFFFF;
  border-left: 3px solid #FFFFFF;
}
 
/* Override the responsive "no-more-tables" stuff */
@media only screen and (max-width: 801px) {
 
  .max-diff-array .no-more-tables table {
    display: table;
    border-collapse: inherit;
  }  
 
  .max-diff-array .no-more-tables thead, 
  .max-diff-array .no-more-tables tbody {
    display: table-row-group;
  }
 
  .max-diff-array .no-more-tables tr {
    left: auto;
    position: relative;
    top: auto;
    display: table-row;
    border: 0 none;
  }  
 
  .max-diff-array .no-more-tables th, 
  .max-diff-array .no-more-tables td {
    display: table-cell;
    text-align: center !important;
    color: #2c3e50;
    font-size: 15px;
  }
 
  .max-diff-array th.answertext { 
    border-right: 3px solid #FFFFFF;
    border-left: 3px solid #FFFFFF;
  }
 
  .max-diff-array .answer-item label span {
    display: none !important;
  }  
}

6) Add a script like this to the question source of the Array (flexible labels) question:
Code:
<script type="text/javascript" charset="utf-8">     
  $(document).ready(function(){
    // Call the maxDiff() function
    // Set the second parameter to true for randomized rows
    maxDiff({QID}, true);
  });
</script>

thanks for helping.

I have another question about design.
I want to use the Implicit Association Test (IAT)
manual.limesurvey.org/Workarounds:_Manip...ation_Test_.28IAT.29
But the template seems that cannot implement on the version 2.5
it will show "undefined", not association terms and the other text elements for the interface into the Question Help section.
my survey:http://www.pushknock.com/projects/limesurvey/index.php/survey/index/sid/412754/newtest/Y/lang/en

thank you

I have updated the workaround page with a new survey and template for the "Implicit Association Test (IAT)" in LimeSurvey version 2.5 - manual.limesurvey.org/Workarounds:_Manip...ascript#Version_2.50
