Hi,

I need to timestamp each individual answer to determine how long it takes participant to answer each question. This is especially important after reading some text or website information. If they take longer then we can determine how well they may have read this previous information.

How would this be possible? I understand that surveys are submitted at the end. Is it possible to timestamp each answer and/or block?

I've enabled time stamp option for this survey but this isn't enough information i.e. only survey creation.
Also when does this time stamp happen? i.e. when the submit button is clicked?

Thanks
Dart

The timestamp is recorded when the busson is clicked.

Only solution I can think of is to use a javascript timer which runs in the background and create a text field or numerical input field after each question and then somehow write the time recorded by javascript into this field. This implies that you use a question-by-question survey.

Take a look at manual -> wokrarounds to find out more about prefilling a form and javascript timer. Searching the forum might bring up additional information, too.

Thanks for that.

I found some JavaScript code for the timer

www.javascript-page.com/timer.html

I tried to paste the timer demo in the workarounds section into the question text but it didn't work. Is this how you enable scripts?
Also I get the following error when I enable the survey now "Survey does not pass consistency check".

I couldn't find any procedure on how to add a javascript code other than it says to add in the question text but it doesn't work for me.

What I need to do is:
1. Start timer when question is displayed.
2. Record this timer value (same timer) when the Next button is clicked.

So will I need to have two seperately activated scripts. The first script is a boiler point question and I'll make sure it doesn't show with conditions. How do I make the next script happen when the next button click?

Its a pitty there isn't a "script" type question but prehaps I'm missing something.

HELP!!

Thanks

There is a filter for security reasons which filters javascript input to prevent XSS attacs. Check config-defaults.php for a setting like "xssfilter", copy this setting to config.php and disable the filter.

To put the recorded time into a textfields I recommend to show the textfield to the user and use javascript to directly place the time of the counter into the text field. This should be possible by addressing the form element directly (DOM).

Please keep in mind that I haven't done something like this before myself. I can only point you to how this should work.
You can try to contact other users who have successfully implemented a timer.

Hi Mazi,

Sounds like hard work given I only have say a day to get it running.
I might miss it and get up to speed with Java scripts in questions
for the next job

Thanks though.

P.S. Prehaps somebody could write something in the manual on a step by step on using Java with LimeSurvey?? Even step by step procedure for the
Java stuff in the workarounds section.

If you are missing some information in the manual feel free to improve it yourself. Our manual is a wiki, everyone can edit it and you can't do much wrong.
So if you miss anything in the manual and you found out how to do it please add this information. Thanks!

Looks like I have no choice now but to implement this feature as the research now requires it.

When I finish this I'll write it up

The following would be a nice feature for the future.
1. A script question type (No need to paste in question).
2. Have extra options to allow admin to insert data fields and capture certain event including key presses.
3. Only administrators can have access to edit/add scripts.
4. Some write a good manual on how to expand Limesurvey through JavaScipting

I need a little help on how to capture the "Next" button event so i can write the data to a researve field and continue with next buttons normal operation. Also how do I write this timer value to my spare field?? I'm guessing I need to know question ID but have no idea

Also is it possible to know when a URL link is clicked and start a timer then?
thanks!!

You can add this as a feature request to the bugtracker. Please describe your problem/solution as detailed as possible.

Regarding the programming questions I recommend to join the developer IRC.

I can't help you with this in detail because I'm not a developer.

Hi,

I have a problem....

When my special question is hidden it won't write value to database.
A good way to test this is to:
1. Create special question and its conditional on another question. So you can hide/unhide it within the same page.
2. Set a value in this special question
3. Hide it
4. Click next or submit.
5. Check responses, hay no entry!!

The value doesn't get cleared either when you hide and unhide question
so it has to do with the submit form part to LimeSurvey.

I also tried forcing it to display just before the submit form is run but that didn't work either.

i.e. document.getElementById('question302'.style.display='';
document.getElementById('display302'.value='on';


I've attached as a txt file and pasted it.

Here's my code :

Question 01
<div id="LS_Timer" style="padding-right: 3px; padding-left: 3px; left: 25px; padding-bottom: 3px; padding-top: 3px; position: absolute; top: -25px; background-color: lime">&nbsp;</div>
<script type="text/javascript">
