==================

I have a script that a few contributors here helped me with, that creates a button that stores date events in a list that is then stored as a multiple short text answer. This works as a way for the user to point to relevant moments during an experiment. The number of short texts is not defined as priori, and is created as the user taps on the button. What I get as answer is a list of dates separated by ",". Now I want to create a following question where the user will describe what was relevant in the moments he/she decided to mark as relevant. For this, I wanted the question to read "You marked X moments as relevant, can you describe why?" How can I refer to this X as the number of multiple texts dynamically created in the previous question?

Here is the code I have been using:

</script>

<div id="buttonplacement"><button id="tapbutton" type="button">Marcar</button></div>
<script type="text/javascript" data-author="Tony Partner">
    
    $(document).on('ready pjax:scriptcomplete',function(){
        
        // Identify this question
        var thisQuestion = $('#question{QID}');
        var thisTextarea = $('textarea.form-control:eq(0)', thisQuestion);
        
        var timestamps = ;
        if($.trim($(thisTextarea).val()) != '') {
            timestamps = $.trim($(thisTextarea).val()),split(',');
        }        
        
        // Listener on the button
        $('#tapbutton').on('click', function(e) {
            var newTimeStamp = Date.now();
            
            timestamps.push(newTimeStamp);
            
            $(thisTextarea).val(timestamps).trigger('keyup');
        });
    });
</script>

Thank you all for the help.

Hi,
it's always better to provide e lss export of these relevant question.

Then you avoid the typo here
 var timestamps = ;
instead of
 var timestamps = ;

Now, what can you do?
My idea is to use a question of type"multiple short text" with two subquestions.
1. The timestamps
2. The count of timestamps

Then you may use this - slightly adapted - script.



And some styling


You will get this

Thank you Joffm.

This worked really nice. I was thinking I had to make Q2 go through Q1 and parse it in the ','. But this is much easier, counting Q1 length after each button press and storing this still in Q1 as SQ002. Then just referring to Q1SQ002 in Q2. Just learned there is a button for this referring to previous answers, which I thought would also be a problem...

Thank you a lot!
