Reusing previous answer online

[Venustiano]

I would like to reuse the previous answer as in the screenshot below

However, when I try to access the variable I get NA. My code is as follows

Do you have an idea how can I use the value of the Toerbelsysvast variable?

Thanks in advance

[dfeistauer]

try a submit between both variables.

[Venustiano]

Adding a submit will move to the next page but I still need to be in the same page and update the note.

[Venustiano]

I also don't understand why I can use the variables in the showif column but not in the label.

[rubenarslan]

The label is generated with rmarkdown (requires a pageload), but the showif is evaluated both with JS (works on the same page). You can also generate the label with JS, but you'd have to write that code yourself.

I see,

Thank you for your reply. Could you point me to an example running javascript in a formr google/excel sheet?

Thanks again

I found a solution

Based on this answer, I implemented the following javascript function

window.onload = function () {
    const dnumber = document.querySelector('[name="Toerbelsysvast"]');
    
    display = document.querySelector('#test_display_number');
    
    dnumber.addEventListener("change", (event) => {
        gnumber = event.target.value
        display.textContent = gnumber;
    })
};

and in the label column

Test display number: <span id="test_display_number"> </span>

However, I still have a question. This code is working only for Runs buy not for Test survey.

Is it possible to include javascript code into Test surveys?

[rubenarslan]

Yes, you can include any Javascript in the survey label, so just make the label of Toerbelsysvaat contain the below:

<script>
window.onload = function () {
    const dnumber = document.querySelector('[name="Toerbelsysvast"]');
    
    display = document.querySelector('#test_display_number');
    
    dnumber.addEventListener("change", (event) => {
        gnumber = event.target.value
        display.textContent = gnumber;
    })
};
</script>
