Expressions without element? Is this a bug? was created by rcha88AA

Hi, I am trying to do some conditional formatting in text boxes.

In my css code, via the 'Source' tab, I have css that contains:

Code:

border: {if(3==2, '2px', '20px')} solid black;

This produces the expected result (good) in the final html on the webpage, which is:

Code:

border: 20px solid black;

But when I try to use an answer as a variable, instead of fixed numbers:

Code:

border: {if(AB05==2, '2px', '20px')} solid black;

The final output is wrapped in a spam element, which is not good for me:

Code:

border: <span id='LEMtailor_Q_0_4'>20px</span> solid black;

The output only gets wrapped in a span if a question/answer is used? What is the reasoning for this?
Is there any way to make the output of the expression 'raw', and not wrapped in a span?
Is it a bug that the output in my first example is not wrapped in a span?

I believe I can achieve what I want via javascript but I think it is neat and simple to use how I trying to.

Thank you for any input!

Because your question AB05 is inside the same page.

You must use questions in previous page only.

Thanks Denis.

I using values from previous pages. (Unless I misunderstand how LS functions)

My situation: My survey displays, I complete the answers, I click submit.
A new page is shown, with my End Message. (Found in 'Survey settings -> Text elements')
It is here in my end message that I want to use the values from questions/answers.
I can display the value as text OK, but it is always inside a element and this is a problem if I want to use the number in javascript or css.

Version 3.14.9
Windows Server 2016
sqlsrv

Thank you

If anyone has my same problem and wants a quick cheap fix, it is quite simple to extract the value from the span element via javascript, which then I can use the value how I want. (Use to hide elements, change styles etc)
AB05 is the code id of the question I want to get the value of the answer from.

Code:

<script type="text/javascript" charset="utf-8">
   $(document).on('ready pjax:complete',function() {
 
      function extractContent(s) {
        var span = document.createElement('span');
        span.innerHTML = s;
        return span.innerText;
      };
 
     var my_value = extractContent("{AB05}");
     alert(my_value);
 
   });
</script>

Due to this being javascript, it is run after the page is complete and is client side.
If I could do what I wanted (use the value in css itself, without LS generating a span element), the value would be created server side, which is nice.

Can you sedn a sample LSS file (with only 2 or 3 questions)

if AB05 is in a page before {AB05} must never shown a span.

Maybe it's fixed in last version.

Try disabling AJAX in the survey theme options.

Checked with 3.17.2, using test{QCODE} for Class : OK, no issue class didn't have span.
I check at end message : no span too.

Ajax mode on or off

Using 3.17.3, I had the same issue.

My sourcecode in a text display-question was:

Code:

<img src="http://localhost\jpgraph\generateimage.php?Param1={P1}&amp;amp;Param2={P2}" />

P1 and P2 are equation-questions.

I can confirm Denis' statement: the -element only appears when using a (equation-)question from the same page (group).
My workaround was adding another group before, which contained only the equation-questions P1 and P2. Both questions where set to "always hide", so the whole group was invisible.

Best regards, Felix.
