Hi, I want to set all of the subquestions' default answer to be "0%" in an array question with dropdown lists.I've tried to use the following javascript, but only the first subquestion's default answer has changed to "0%", all the others has remained "please choose".  Can someone help me please? Many thanks! I have attached my question below. 
Code:
</script><script type="text/javascript" charset="utf-8">       $(document).ready(function(){           $('#question{QID}').each(function(i) {             if($(this).val() == '') {                 $('option[value!=""]:first', this).attr('selected', 'selected');             }         });     });   </script>

Hi,
the easy way:
use an equation before your question to set the default values.
Like
{Q03_SQ001='A1'}
{Q03_SQ002='A1'}
{Q03_SQ003='A11'}  // Here you said, the default value is 100%
{Q03_SQ004='A1'}

 

And in my opinion it is better to code the answer options according the persentages.
Not
"A1" = 0%
"A2" = 10%
...
"A11" = 100%
Very difficult to calculate something.

But
0 = 0%
10 = 10%
...
100 = 100%

Hi Joffm, thank you for your prompt reply. I saw you are an active member and have already helped many people on the forum. Great to learn from you.

I am still very new to LimeSurvey, so I don't know how to set an equation before the question. Do you mind attaching your modified question/survey in the post. I will try to study your setting on my end.

Another question is - If I want to make sure the sum of the percentage must equal 100%, how can I set up the validation?

Many thanks for your help in advance!!

Joffm, do you not need an IF() statement to check if the question is already answered?

Regarding the JavaScript, this will set all dropdowns except the third to the first value and set the third dropdown to 100. Note that the answer codes are changed to numerics as Joffm suggests.  
 
 
Code:
<script type="text/javascript" data-author="Tony Partner"> $(document).on('ready pjax:scriptcomplete',function(){ // Default 0 for all but SQ003 $('#question{QID} select.form-control').not('[id$=SQ003]').each(function(i) { if($(this).val() == '') { $(this).val($('option[value!=""]:first', this).attr('value')).trigger('change'); } }); // SQ003 defaults to 100% if($('#question{QID} select.form-control[id$=SQ003]').val() == '') { $('#question{QID} select.form-control[id$=SQ003]').val('100').trigger('change'); } }); </script>

Regarding the question validation, try this (after the answer codes are changed to numerics):  

Code:
sum(self) == 100

@tpartner, Yes I need one.
In my example it is included.

With validation (the same Tony showed)

Joffm

By the way:
Why don't you use a question of type "multiple numerical input"? Only to have some drop-downs?
Here all your requirements are built-in.
There are "default answers",
 
there isthe validation
 

 

If you want to remove the "Remaining" and "Total" display, I did it with this css in the question text.
Code:
<style> .ls-group-remaining, .ls-group-total {   display:none; } </style>
