Required fields in Mechanical Turk

Question

Is there any way to make fields required in an Amazon Mechanical Turk HIT? I get some blank responses to the textboxes or radiobuttons in my HTML form and the Amazon's documentation doesn't seem to provide any mechanism for validation.

The easiest way would probably be to use Amazon's API call 'createHIT' to create your HIT: http://docs.amazonwebservices.com/AWSMechTurk/latest/AWSMturkAPI/index.html?ApiReference_CreateHITOperation.html

Then, you can specify your HIT questions using a 'questionForm' data structure, which allows defining any field as 'required', and enforces it when the form is submitted.

Thanks. I have used the API before and I think I'm limited when I used the questionsForm and my HTML form is more complex. I was hoping that there is some kind of validation mechanism when the users are submitting the HIT. – msha Nov 24 '10 at 16:33
yep, I've actually bumped into your question while looking a solution for the same issue :) – etov Nov 30 '10 at 15:05

I think adding the required attribute to your element works fine.

<input class="form-control" id="url" name="url" placeholder="Enter URL here" required="" type="url" />

I would suggest you create your HIT on an external server, used javascript for form validation and then display the questionnaire on Mechanical Turk using an iFrame.

If you don't mind creating an external web app to host your question form, you can create an external HIT and do your validation there.
