I have tried to write a script for such a case, although the Submit button is simply disabled, not hidden.
I would appreciate if you guys can check it out because I am not sure it is bugless.
The code is placed into a radio list type of question with 'yes' and 'no' answer choices, coded as A1 and A2.

Code:

<script type="text/javascript" charset="utf-8">    
  $(document).ready(function() {
 
    // Identify this question
    var thisQuestion = $('#question{QID}');
 
    // Initially disable the Next/Submit button
    $('#ls-button-submit').prop('disabled', 'true').addClass('ui-state-disabled');
 
    // Listeners on Yes/No radios to toggle the Next/Submit button
    $('input:radio[value="A1"]', thisQuestion).click(function(){
      $('#ls-button-submit').prop('disabled', '').removeClass('ui-state-disabled');
    });
    $('input:radio[value="A2"]', thisQuestion).click(function(){
      $('#ls-button-submit').prop('disabled', 'true').addClass('ui-state-disabled');
    });
    });
</script>

Thanks in advance! A survey sample attached.

PS. Does anyone know why we no longer can select in which language the code is displayed on the forum? It is only gray now.

I'm using the latest LS 3.22 hosted on LS servers, not installed locally.

The script looks good.

You can still manually add a language to the code block - I have edited your post accordingly.

Many thanks for checking it out! It is just I have had some strange behavior of conditioned questions not being displayed properly after adding this code. When the survey is active the conditions work, but when it is inactive, then they don't work in the preview.

What should be added to the block, for example, for JS?

There are no submit button in preview, then the script broke when you try to update an attribute

Add this

Code:

if(!$('#ls-button-submit').length != 1) {
return;
}

just before // Identify this question

I don't understand why Expression Manager broke if there are error here … Maybe limesurvey core can do somthing here : EM javascript work with (some) broken JS in question text.

Perhaps I didn't add it in the right place, but it brakes the script.

Code:

<script type="text/javascript" charset="utf-8">    
  $(document).ready(function() {
 
if(!$('#ls-button-submit').length != 1) {
return;
}
    // Identify this question
    var thisQuestion = $('#question{QID}');
 
    // Initially disable the Next/Submit button
    $('#ls-button-submit').prop('disabled', 'true').addClass('ui-state-disabled');
 
    // Listeners on Yes/No radios to toggle the Next/Submit button
    $('input:radio[value="A1"]', thisQuestion).click(function(){
      $('#ls-button-submit').prop('disabled', '').removeClass('ui-state-disabled');
    });
    $('input:radio[value="A2"]', thisQuestion).click(function(){
      $('#ls-button-submit').prop('disabled', 'true').addClass('ui-state-disabled');
    });
    });

Try wrapping the whole thing in an if() statement that looks for the submit button:

Code:

<script type="text/javascript" charset="utf-8">    
  $(document).ready(function() {
 
    if($('#ls-button-submit').length > 0) {
      // Identify this question
      var thisQuestion = $('#question{QID}');
 
      // Initially disable the Next/Submit button
      $('#ls-button-submit').prop('disabled', 'true').addClass('ui-state-disabled');
 
      // Listeners on Yes/No radios to toggle the Next/Submit button
      $('input:radio[value="A1"]', thisQuestion).click(function(){
        $('#ls-button-submit').prop('disabled', '').removeClass('ui-state-disabled');
      });
      $('input:radio[value="A2"]', thisQuestion).click(function(){
        $('#ls-button-submit').prop('disabled', 'true').addClass('ui-state-disabled');
      });
    }
    });
</script>

Personnaly i prefer to quit when not needed than wrap inside a big if when needed. I think it's more clear

Yeah but I think that's a matter of personal preference.

There is very little difference in execution resources between the two methods, although mine should be marginally quicker as the code inside the IF() statement is not executed.
