Compulsory answers and blocking keys

ianpgrant

Hi
I am creating an experiment and would like to stop the participants proceeding to the next item until they have answered all questions. I am using the form_base item. Does anybody know how I can do this. Additionally, I would like to block all other keys other that the enter key (and of course the esc key) when using likert scales. Is there anyway of doing this. Would be very grateful for your help.

Hi Ian,

If you search this forum for terms like 'form validation' you will find a few related discussion, such as this one:

• http://forum.cogsci.nl/index.php?p=/discussion/1121/solved-questionnaire-issues

Essentially, you'll need to use a bit of inline_script to accomplish this, and the details depend on what your form looks like, and what kind of input validation you want to implement.

Additionally, I would like to block all other keys other that the enter key (and of course the esc key) when using likert scales.

What do you mean exactly? The rating_scale widget (which I assume is what you mean?) accepts only mouse clicks to begin with.

Cheers!
