Hi all,

I am asking a question of type matrix of numbers and using the checkboxes.

I tell you that I need to exclude the last two options from each column

That is, if SQ005_A and SQ006_A
are checked, exclude all others SQ001_A SQ002_A SQ003_A SQ004_A

The same happens with column B, C, D

I found something very useful in the forum, but it only works to make the last row exclusive, and I'm looking to make the last two exclusive.

I appreciate your help too much

Err...what did you find?

Hi @tpartner

Thanks for answering,

I found this script:

<script type="text/javascript" charset="utf-8">
$(document).on('ready pjax:scriptcomplete',function(){
 
// Identify this question
var qID = '{QID}';
var thisQuestion = $('#question'+qID);
 
// Assign column-specific attributes and classnames
$('tr.subquestion-list', thisQuestion).each(function(i) {
$('> *', this).each(function(i) {
$(this).attr('data-column', i);
});
});
$('tr.subquestion-list:last td.answer-item', thisQuestion).addClass('exclusive-item');
 
// A function to un-check boxes
function resetCheckbox(thisItem) {
$(':hidden', thisItem).val('');
$(':checkbox', thisItem).prop('checked', false).trigger('change');
}
 
// Listener on the checkboxes
$(':checkbox', thisQuestion).on('change', function(e) {
if($(this).is(':checked')) {
var thisItem = $(this).closest('.answer-item');
var thisColumn = $(thisItem).attr('data-column');
var items = $('td.answer-item[data-column="'+thisColumn+'"].exclusive-item', thisQuestion);
if($(thisItem).hasClass('exclusive-item')) {
items = $('td.answer-item[data-column="'+thisColumn+'"]:not(.exclusive-item)', thisQuestion);
}
$.each(items, function(i, el) {
resetCheckbox(el);
});
}
});
});
</script>

In this post:

As I mentioned before, it works very well excluding the last row of options, but I wish it was like this for the last two.

Thanks again.

What LimeSurvey version do you use?

Can you attach a small sample survey (.lss file) containing only that question and your JavaScript?

Thanks Tony,

I am attaching the lss survey with the question and the script.

I tell you that I am using 3.25 and 2.50. I ran it in both versions and with the script it works for both versions.

This script will render the last two rows of an array-numbers-checkboxes question as exclusive.
