Only one character allowed was created by Vinicos

Hello

I have created a multiple short text question with 3 subquestions. I want the first and the third subquestion to allow only one-character answers. I have already used a subquestion validation equation, but I actually want that the field accepts only one character (just like when we set a maximum of character in a numeric question). Is this possible?

Thanks

Place this script in the question source:

Code:

<script type="text/javascript" charset="utf-8">  
 
  $(document).on('ready pjax:scriptcomplete',function(){
 
    // First input
    $('#question{QID} input:text:eq(0)').attr('maxlength', 1);
    // Third input
    $('#question{QID} input:text:eq(2)').attr('maxlength', 1);
    });
</script>

Thanks a lot.
It works well.
Is it also possible to allow participants only to use letters (not as a question validation equation)?

This will also remove all non-alpha characters:

Code:

<script type="text/javascript" charset="utf-8">  
 
  $(document).on('ready pjax:scriptcomplete',function(){
 
    // First input
    $('#question{QID} input:text:eq(0)').attr('maxlength', 1);
    // Third input
    $('#question{QID} input:text:eq(2)').attr('maxlength', 1);
 
    // Listener on inputs
    $('#question{QID} input:text:eq(0), #question{QID} input:text:eq(2)').on('keyup', function(e) {
      var thisValue = $.trim($(this).val());
 
      // Strip out non-alpha characters
      newValue = thisValue.replace(/\W/g,'').replace(/\d/g,'');
      $(this).val(newValue).trigger('change');
    });
    });
</script>

Sorry to bother again.
But, in this case, I would like the three subquestions to allow only letters. The first and the third only one character, but the second as much as the participants want (but only letters). Would the syntax be different then?

Change:

Code:

$('#question{QID} input:text:eq(0), #question{QID} input:text:eq(2)').on('keyup', function(e) {

To:

Code:

$('#question{QID} input:text').on('keyup', function(e) {
