Just for documentation: I have found a way to achieve what I was looking for in the first post. Since I have almost no experience with java script, it was pretty exhausting to tinker around with the two classes in javascript. This is the code where only some of the multiple choice answers are mutually exclusive:
Code:
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
// Identify this question
var thisQuestion = $('#question{QID}');
// Add some classes
var sqCount = $('.question-item', thisQuestion).length;
$('.question-item:eq('+(sqCount-22)+')', thisQuestion).addClass('non-exclusive-item'); // first item
$('.question-item:eq('+(sqCount-21)+')', thisQuestion).addClass('non-exclusive-item'); // 2nd item
$('.question-item:eq('+(sqCount-20)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-18)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-17)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-16)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-14)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-13)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-12)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-10)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-9)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-8)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-6)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-5)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-3)+')', thisQuestion).addClass('non-exclusive-item');
$('.question-item:eq('+(sqCount-2)+')', thisQuestion).addClass('non-exclusive-item'); // // 2nd last item
$('.question-item:eq('+(sqCount-1)+')', thisQuestion).addClass('non-exclusive-item'); // Last item
// Handle exclusive items
$('input[type="checkbox"]', thisQuestion).on('change', function(e) {
if($(this).is(':checked') ) {
var thisItem = $(this).closest('.question-item');
var actionItems = $('.question-item', thisQuestion).not($(thisItem));
if($(thisItem).hasClass('non-exclusive-item')) {
actionItems = $('.exclusive-item', thisQuestion);
}
actionItems.each(function(i) {
$('input[type="checkbox"]', this).prop('checked', false).trigger('change');
$('input:hidden', this).attr('value', '');
$('input[type="text"]', this).val('').trigger('keyup');
});
}
});
$('input[type="text"]', thisQuestion).on('keyup change', function(e) {
var thisInput = $(this);
setTimeout(function() {
$(thisInput).closest('.question-item').find('input[type="checkbox"]').trigger('change');
}, 200);
});
});
</script>
I took the javascript from here and modified it my needs:
www.limesurvey.org/forum/can-i-do-this-w...oxes?start=15#171315
Therefore, there are some parts "junk code" left (in genetics they would be called introns
), however, the javascript works.
An example, which combines secondary answer options (
www.limesurvey.org/manual/Workarounds:_M..._options.22_question
) together with choosing only one primary answer and one secondary answer is attached (theme needs to be imported for secondary answer options). For me this workaround was very helpful.
