Hello!
I am using LS since 2012 and it is working fine for my purposes!
I need to save some paradata about the respondent's device (cookies enabled, browser name, engine) in the answers file.
To do this I created a question (Q10, type: equation):



I added the following code to the question:

<p id="device">
</p>
<script>
document.getElementById("device").innerHTML =
"Cookies Enabled is: " + navigator.cookieEnabled
+ "; Browser name is: " + navigator.appName
+ "; Browser code name is: " + navigator.appCodeName
+ "; Engine: " + navigator.product
</script>

In the preview I can see the data I am requesting:

My problem is that the data should be stored in the answers, but it doesn't work.
(I also need to hide the question, but this is the second step of my problem).
What is wrong in my text? Maybe something in the code (I am not expert of Javascript !)?
I am using LS Version 2.05+ Build 141229.
Any suggestion would be appreciated!!!!
Thanks

Place the following script into a short-text question. It will hide that question and load your data.
Or better, this in the source of a multiple-short-text with 3 sub-questions:

Wow!!!!
It works perfectly!
Thank you Tony for your precious help!!!!

Hi Tony,

This does not work in the latest version any more. Do the scripts need some updating? Thanks!!!

Try this:

Still doesn't seem to work. The fields are returning blanks on the view responses page.

For browser name an version : gitlab.com/SondagesPro/QuestionSettingsType/findUserAgentInfo

Unsure it still work on 3.0 but can be tested

Is your survey set up to use Javascript?

Still doesn't seem to work. The fields are returning blanks on the view responses page.

It works for me. Can you activate a test survey and give a link here?

Sorry guys! Yes the new script works! I wasn't sure why it didn't at first but after replacing the entire script it worked! I had initially only replaced the 'ready pjax:scriptcomplete' portion. Thanks everyone!

Hi guys, I followed your steps but data is not being saved. What am I missing?

Here's what I did:
1)added new multiple short text question named device
2)pasted the following code in Source
<script type="text/javascript" charset="utf-8">
$(document).on('ready pjax:scriptcomplete',function(){

// Identify this question
var thisQuestion = $('#question{QID}');

// Hide this question
thisQuestion.hide();

// Load the text input
$('input:text:eq(0)', thisQuestion).val(navigator.cookieEnabled);
$('input:text:eq(1)', thisQuestion).val(navigator.appName);
$('input:text:eq(2)', thisQuestion).val(navigator.product);
});
</script>
3) saved the question


Here's a screenshot

Dear bedendo,
to answer we should know which version you are using.
However, on the latest release (3.2x) I found useful this solution:

Best,

Thanks, Enzo. I'll follow your suggestion.
I'm using Version 3.19.3+191023
Should I update or am fine with this version?
Many thanks,
Andre
