Array filter with exclusive option was created by wireframemedia
I have a very complex survey which uses a lot of array filters to feed answers from other questions. I have one question which also requires an exclusive option to appear along with the filtered results. How can I accomplish this? The filtering seems to work fine but the exclusive option does not show up.

Thank you.

If I understand correctly, you want one option of the array to always show and all others to be filtered by a multi-opt question.

To do this you will need to build your own filter with JavaScript.

Hi Tony,

Yes that is exactly what I need to do. Can you provide a bit more direction and a sample of the code needed to accomplish this? I am new to LimeSurvey.

Thank you.

Okay, this should do the trick for an array that uses radio buttons (not array-multi-flexible-numbers or array-multi-flexible-text).

Set up your survey to use JavaScript and place the following script in the source of the multi-option question.

Replace "111" (line 6) with the multi-option question ID and "222" (line 7) with the array question ID.

Note that the answer codes of both questions MUST be identical EXCEPT for the answer code of the option that you want permanently displayed.
Code:
<script type="text/javascript" charset="utf-8">
 
    // Filter array by multi-opt but always show default option
    $(document).ready(function(){
 
        var q1ID = 111;                       
        var q2ID = 222;
 
        // Find the survey and group IDs
        if($( 'input#fieldnames' ).length != 0) {
            var fieldNames = $('input#fieldnames').attr('value');
            var tmp = fieldNames.split('X');
            var sID = tmp[0];
            var gID = tmp[1];
        }
 
        var optionCode = '';
 
        // Initially hide and clear all unwanted array rows
        $('#question'+q1ID+' input.checkbox').each(function(i) {
 
            inputID = $(this).attr('id');
            var tmp2 = inputID.split(q1ID);
            var optionCode = tmp2[1];
 
            if ($(this).attr('checked') == false) {
                $('#question'+q2ID+' table.question tbody#javatbd'+sID+'X'+gID+'X'+q2ID+optionCode+'').hide();
 
                $('#question'+q2ID+' table.question tbody#javatbd'+sID+'X'+gID+'X'+q2ID+optionCode+' input.radio').each(function(i) {
                    $(this).attr('checked', false);
                });
            }
        });
 
        // Listener on radio inputs
        $('#question'+q1ID+' td.answer, #question'+q1ID+' td.answer input.checkbox').click(function() {
 
            // Hide and clear all unwanted array rows
            $('#question'+q1ID+' input.checkbox').each(function(i) {
 
                inputID = $(this).attr('id');
                var tmp2 = inputID.split(q1ID);
                var optionCode = tmp2[1];
 
                if ($(this).attr('checked') == false) {
                    $('#question'+q2ID+' table.question tbody#javatbd'+sID+'X'+gID+'X'+q2ID+optionCode+'').hide();
 
                    $('#question'+q2ID+' table.question tbody#javatbd'+sID+'X'+gID+'X'+q2ID+optionCode+' input.radio').each(function(i) {
                        $(this).attr('checked', false);
                    });
                }
                else {
                    $('#question'+q2ID+' table.question tbody#javatbd'+sID+'X'+gID+'X'+q2ID+optionCode+'').show();
                }
            });
 
        });
 
    });
 
</script>

Just because of interest: What happens if there is an additional answer item in a following question that doesn't exist at the previous multiple choice question?
Will it not be listed at all when using array filter?

Yeah, if you enable the array filter in advanced settings, no options will be shown in the array unless they are checked in the multi-options question. This includes array options that don't exist in the multi-options question.

Tony,

Thank you so much, this is great!

I tried it but the exclusive option is still not showing up. I have to use checkboxes (not radio buttons) for multiple responses; could that be why it is not working?

Along with the exclusive option, I need the "other option" to also show up regardless of the answers/filter piping in from a previous question so those two will be constants.

Thanks.
Dawna

...the exclusive option is still not showing up...

Did you disable the array filter in the advance settings for the array question?

Along with the exclusive option, I need the "other option" to also show up regardless of the answers/filter piping in from a previous question so those two will be constants.

I'll have to look into that tonight.

I have to use checkboxes (not radio buttons) for multiple responses

The script is designed for a multi-options (checkbox) followed by an array (radio buttons) question.

Hi Tony,

Yes I did and when I did that, all original options showed up, none of the previously selected options appeared (no filtering) so I re-inserted it. I'll remove it again but then it does not filter at all. I did a JavaScript test and it is reading JS fine, just not doing what we want yet.

The survey requires a multi-option (checkbox) array followed by another multi-option (checkbox) array filtered and including the exclusive option and other option as well....very complicated but it's for a high-end client and it's what they want.

Thank you for your help. I appreciate it.

Note that question IDs change when setting up a new question so don't forget to adjust the IDs.

Hmm...now I'm a little confused. I thought you were filtering an array with a multiple options question (see my screenshot).

Can you activate a sample survey or provide a screenshot?
