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.

Answer 1

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.

Answer 2

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" />

Answer 3

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.

Answer 4

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.
