Hi,
Is there a way to notify someone that he didn't answer a non-mandatory question?
I want to do this because some participants might skip a question unintentionally, and not necessarily because it was non-mandatory.

Thanks!
David

You can use JavaScript to do this.

What question type is it?

Array with 5 sub-questions.

So, you want to warn if they skip any row in the array or just if they skip the whole array?

I was thinking about warning them if they skipped any row in the array, but it would be great to have the code for skipping a whole question as well for future use (if they unintentionally skip a yes/no question, for example).

Thanks!

EDIT: i'd like the message to say something like: "You did not answer question {QUESTION-NUMBER}. Are you sure you don't want to answer that question?"

Or for a specific subquestion in an array: "You did not answer subquestion {SUBQUESTION_NUMBER} in question {QUESTION-NUMBER}. Are you sure you don't want to answer that subquestion?"

1) Set up your survey to use JavaScript .

2) Add the following script to the source of the array. Replace "QQ" with the array question ID .

The script interrupts the Next/Submit process and if an unanswered row is found in the array, the respondent is asked if they would like to continue. This script is for array questions but could be modified for radio questions.
<script type="text/javascript" charset="utf-8">
 
	$(document).ready(function() {
 
		checkArray(QQ, 'You did not answer the question. Do you really want to continue?')
 
		function checkArray(qID, msg) {
 
			// Interrupt next/submit function 
			$('#movenextbtn, #movesubmitbtn').click(function(){
 
				var failTest = '';
 
				$('#question'+qID+' tbody[id^="javatbd"]').each(function(i) {
					if($('input.radio:checked', this).length < 1) {
						failTest = 1;
						$('th, td', this).css({'background':'pink'});
					}
					else {
						$('th, td', this).css({'background':''});
					}
				});
				if(failTest == 1) {
					if(confirm(msg)) {
						return true;
					}
					else {
						return false;
					}
				}
			});
		}
 
	});
 
</script>

Thanks so much, worked like a charm!

I noticed it highlights the unanswered question in pink, but is it also possible to make the pop-up message say which question was left unanswered?

...but is it also possible to make the pop-up message say which question was left unanswered?

Yes, you can just modify the message in the function call:
checkArray(QQ, 'You did not answer question 4. Do you really want to continue?');

Oops, just noticed a possible bug in 1.92...use this instead:
<script type="text/javascript" charset="utf-8">
 
	$(document).ready(function() {
 
		checkArray(QQ, 'You did not answer the question. Do you really want to continue?');
 
		function checkArray(qID, msg) {
 
			// Interrupt next/submit function 
			$('#movenextbtn, #movesubmitbtn').click(function(){
 
				var failTest = '';
 
				$('#question'+qID+' tbody[id^="javatbd"]').each(function(i) {
					if($('input.radio:checked', this).length < 1) {
						failTest = 1;
						$('th, td', this).css({ 'background':'pink' });
					}
					else {
						$('th, td', this).css({ 'background':'' });
					}
				});
				if(failTest == 1) {
					if(confirm(msg)) {
						return true;
					}
					else {
						return false;
					}
				}
			});
		}
 
	});
 
</script>

I see, Thanks!

Is it possible to insert such a piece of code into the template instead of putting it in each question, so that the survey automatically checks for unanswered questions in each page and then notifies the participant about it?

Hello,

For pseudo non-mandatory question, i use a lot:
- Add a 'I don't want to answer' answer
- Set to mandatory

:)

Yes, you can put this in template.js but if you want to check every question in the survey, you will need different code for every question type and search for those types on every page.

I am trying to use this script with LS 2.54, but it isn't working. I am assuming it will need to be updated? Would someone be able to help with this?

This will work in 2.x versions:

<script type="text/javascript" charset="utf-8">
 
	$(document).on('ready pjax:scriptcomplete',function(){
 
		checkArray('{QID}', 'You did not answer the question. Do you really want to continue?');
 
		function checkArray(qID, msg) {
 
			// Interrupt next/submit function 
			$('#movenextbtn, #movesubmitbtn').on('click', function(){
 
				var failTest = '';
 
				$('#question'+qID+' tr[id^="javatbd"]').each(function(i) {
					if($('input:radio:checked', this).length < 1) {
						failTest = 1;
						$('>', this).css('background-color', '#E74C3C');
					}
					else {
						$('>', this).css('background-color', '');
					}
				});
				if(failTest == 1) {
					if(confirm(msg)) {
						return true;
					}
					else {
						return false;
					}
				}
			});
 
			$('#question'+qID+' input:radio').on('click', function(){
				$(this).closest('tr').find('th, td');.css('background-color', '');
			});
		}
 
    });
</script>

And, for the record, this will work in 3.x:

<script type="text/javascript" charset="utf-8">
 
	$(document).on('ready pjax:scriptcomplete',function(){
 
		checkArray('{QID}', 'You did not answer the question. Do you really want to continue?');
 
		function checkArray(qID, msg) {
 
			// Interrupt next/submit function 
			$('#ls-button-submit').on('click', function(){
 
				var failTest = '';
 
				$('#question'+qID+' tr[id^="javatbd"]').each(function(i) {
					if($('input:radio:checked', this).length < 1) {
						failTest = 1;
						$(this).addClass('has-error');
					}
					else {
						$(this).removeClass('has-error');
					}
				});
				if(failTest == 1) {
					if(confirm(msg)) {
						return true;
					}
					else {
						return false;
					}
				}
			});
 
			$('#question'+qID+' input:radio').on('click', function(){
				$(this).closest('tr').removeClass('has-error');
			});
		}
 
    });
