Loop through EM variables

Loop through EM variables was created by rhg
I have a multiple response question with the qcode "Q1". The subquestions are coded "SQ001", "SQ002", etc. I want to loop through responses in a later question (let's call it "Q2") based on the responses selected in "Q1".

Currently, I have to write a couple lines of code for each subquestion within my loop, like this:
Code:
for(var i =1;i<=9;i++){ $("#javatbd{SGQ}" + i).hide(); if('{Q1_SQ001.NAOK}' == 'Y' ) { $("#javatbd{SGQ}" + 1).show(); } if('{Q1_SQ002.NAOK}' == 'Y' ) { $("#javatbd{SGQ}" + 2).show(); } if('{Q1_SQ003.NAOK}' == 'Y' ) { $("#javatbd{SGQ}" + 3).show(); } if('{Q1_SQ004.NAOK}' == 'Y' ) { $("#javatbd{SGQ}" + 4).show(); } if('{Q1_SQ005.NAOK}' == 'Y' ) { $("#javatbd{SGQ}" + 5).show(); } if('{Q1_SQ006.NAOK}' == 'Y' ) { $("#javatbd{SGQ}" + 6).show(); } if('{Q1_SQ007.NAOK}' == 'Y' ) { $("#javatbd{SGQ}" + 7).show(); } if('{Q1_SQ008.NAOK}' == 'Y' ) { $("#javatbd{SGQ}" + 8).show(); } if('{Q1_SQ009.NAOK}' == 'Y' ) { $("#javatbd{SGQ}" + 9).show(); } }

I'd like to replace '{Q1_SQ001.NAOK}' with something like '{Q1_SQ00' + i + '.NAOK}' but it doesn't work. Is there a way to do this where I don't have to repeat my code for each subquestion?

Why are you doing this with Javascript instead of with sub-question relevance?

(I also don't understand why you have 9 IF statements in every iteration of the loop)

There is no sub-question relevance option for radio button, it is available for checkbox. I have 9 if statement so that I can replace VAR in {Q1_SQ00<VAR>.NAOK} by number

If it's a list-radio, you can use array filter - www.limesurvey.org/manual/Question_type_...r_.28array_filter.29

I am not sure I understand. See below example:

Which are your favorite cities? (checkbox question)
a. London
b. NY (selected)
c. LA
d. Miami (selected)

Say, the next question is which is your most favorite? (radio button) (it should show the options selected in above question)
a. NY
b. Miami

I have used JS to solve this but I am not sure how I should use array filter to use it.

Did you look at the manual ? Put the code of checkbox question in the array filter of the radio list.
