Prefill array (radio) was created by lwolters
Hi,

I have an array that's used as an example-question. Therefore I need to prefill the answers.
SID: 855275
GID: 6068
QID: 50438

I have two subquestions (SQ001 and SQ002) and four answer-options (coded 0,1,2,3,4).
The answer on SQ001 needs to be the option coded 1, and the answer on SQ002 the option coded 2.

I tried this:
Code:
<script type="text/javascript" charset="utf-8">
$(document).ready(function() {
$('#answer855275X6068X50438SQ001_1').attr('checked',true);
 $('#answer855275X6068X50438SQ002_2').attr('checked',true);
</script>

That doesn't work.
Can anyone help me with this?
Thnx!

Liselot

I missed a closing accolade in the code above, but that's not the solution.

Hi, Liselot,

why the Javascript?
It's easily done by an equation.
Before your question (e.g. with code Q1) insert an equation.
In the question text insert:
{Q1_SQ001=1}
{Q1_SQ002=2}

That's it.

Best regards
Joffm

It seems to me that both of those approaches will reset the question to the default values when returning to the group.

I would do this with JavaScript:

Code:
<script type="text/javascript" charset="utf-8">  
  $(document).ready(function() {    
 
    // Default answer for Row "SQ001"
    if($('#question{QID} .answers-list[id$="SQ001"] input.radio:checked').length == 0) {
      $('#question{QID} input.radio[id$="SQ001-1"]').trigger('click');
    }  
 
    // Default answer for Row "SQ002"
    if($('#question{QID} .answers-list[id$="SQ002"] input.radio:checked').length == 0) {
      $('#question{QID} input.radio[id$="SQ002-2"]').trigger('click');
    }
    });
</script>
Cheers,

Both thank you very much for your reply. In this case Joffm's solution will do, because the question is only used as an example en the data is not used.

Sorry for reopening this thread - but I was wondering how I could prefill the rows based on previous answers rather than fixed values (as used here)? To be more specific: I have the same questionnaire embedded twice as an array (in different question groups) and want to transfer the answers of the array to the second one so that participants can see their previous answers and adapt them if necessary. I guess I can use a code similar to the one posted here, but I was not able to find out which parameter to change.

I'd really appreciate your help! Thanks a lot!

    }

    if($('#question{QID} .answers-list[id$="SQ002"] input.radio:checked').length == 0) {
      $('#question{QID} input.radio[id$="SQ002-2"]').trigger('click');
    }
    });
</script>

Hi,
though I am sre that Tony will provide a javascript solution, here something to do it with EM
Question of type equation after the first array:

{Q2_SQ001=if(is_empty(Q2_SQ001),Q1_SQ001,Q2_SQ001)}
{Q2_SQ002=if(is_empty(Q2_SQ002),Q1_SQ002,Q2_SQ002)}
{Q2_SQ003=if(is_empty(Q2_SQ003),Q1_SQ003,Q2_SQ003)}
...

But: What do you want to happen, if the respondent adapts the second array, then goes back to the first, changes something, and then proceeds again to the second array.
My code avoids that changes are reflected.
