Hi!

I need to hide some cells of the array B based on the answer in the array A.

For example, if question Q001 of the array A is not answered, so the question Q001 of the array B must be hide.

Thanks in advance.

Hi, Alessandra,

you are not very clear.
You say you would like

to hide some cells of the array B


But here it seems you want to hide some subquestions

the question Q001 of the array B must be hide


Well, assuming you use a "normal" arrayA with subquestions "SQ001", "SQ002", ...
This array seems to be "not mandatory", because you say

if question Q001 of the array A is not answered

.

Now you already know the relevance equation of the subquestions of arrayB
!is_empty(arrayA_SQ001)
!is_empty(arrayA_SQ002)
...
meaning: the subquestions of arrayB are only displayed if this subquestion in arrayA is NOT empty.



Joffm

P.S. If the "not answered" means that the respondent clicked "not answered" it's a bit different:
arrayA_SQ001!=[code_no_answer]

Hi Joffm,
thanks for your prompt reply.
I've explained myself badly.
In attachment you can find my LimeSurvey example.

I need that subquestion D2_D2Y1xD2X1 on page2 to be hidden if subquestion D1_D1Y1xD1X1 is not answered.

In the attached images, I've circled in red the subquestion that must be hidden on page 2.

Thanks in advance.
Alessandra

As far as I know, the only way to do that would be with JavaScript.

Do you need it for all cells in the second array?

Hi tpartner,
thank you for the reply.

Yes, I need it for all cells in the second array.

I've found the following Java script in the web, but I don't be able to adapt it for my necessity.


<script type="text/javascript" charset="utf-8">

$(document).ready(function() {

$('input[name="69965X2X10SQ001_SQ001"]').attr('disabled', 'disabled');

});

</script>

I don't know if it is the correct java script...
Thanks for your help in advance.

1) Place something like this in the source of the second array. It will render a hidden array of all answered Q1 sub-question codes that we can access with JavaScript.

<div class="hidden equation">
	{implode(',', if(D1_D1Y1_D1X1 == '1', 'D1Y1_D1X1', ''), if(D1_D1Y1_D1X2 == '1', 'D1Y1_D1X2', ''), if(D1_D1Y1_D1X3 == '1', 'D1Y1_D1X3', ''), if(D1_D1Y2_D1X1 == '1', 'D1Y2_D1X1', ''), if(D1_D1Y2_D1X2 == '1', 'D1Y2_D1X2', ''), if(D1_D1Y2_D1X3 == '1', 'D1Y2_D1X3', ''), if(D1_D1Y3_D1X1 == '1', 'D1Y3_D1X1', ''), if(D1_D1Y3_D1X2 == '1', 'D1Y3_D1X2', ''), if(D1_D1Y3_D1X3 == '1', 'D1Y3_D1X3', ''), if(D1_D1Y4_D1X1 == '1', 'D1Y4_D1X1', ''), if(D1_D1Y4_D1X2 == '1', 'D1Y4_D1X2', ''), if(D1_D1Y4_D1X3 == '1', 'D1Y4_D1X3', ''))}
</div>


2) Add this script to the source of Q2. It will loop through that hidden array and disable Q2 sub-questions if the corresponding Q1 sub-question was not answered.

<script type="text/javascript" charset="utf-8">
	$(document).on('ready pjax:scriptcomplete',function(){
		var q1Code = 'D1';
		var q2Code = 'D2';
		var answeredQ1 = $.trim($('#question{QID} .hidden.equation:eq(0)').text()).split(',');
 
		// Loop through answers from Q1 and add classes to the corresponding Q2 inputs
		$.each(answeredQ1, function(i, val) {
			var re = new RegExp(q1Code, 'g');
			var q2CellCode = val.replace(re, q2Code);
			if(val != '') {
				$('#question{QID} input[type="text"][id$="'+q2CellCode+'"]').addClass('relevant');
			}
		});
 
		// Disable irrelevant items
		$('#question{QID} input[type="text"]:not(.relevant)').prop('disabled', true).val('');
 
 
	});
</script>





Here is your sample survey back with those modifications:
