I'm certainly relatively effectively conscious that checkboxes and radio buttons are grouped by the "name" attribute, and so are my readers.

This instance will cover the submit button till "Yes" is chosen in a checkbox field. The reply is that even when you employ javascript to replace the worth of a field, FormAssembly won't recognise the sector has been modified till there's an specific consumer interaction. Without that '.click()' in your code, you'll see the worth of the checkbox change however the conditional rule won't fire.

When the shape first loads, the login_attempts hidden factor has an empty string as its value. When the onClick occasion of the form's button is triggered for the primary time, the perform above units the worth of the hidden factor to 1.
