Set Field Values on Form Submission

In this section "hidden (not visible)" means an input where type="hidden" or any field that is not visible at the time of submit (e.g., display:none).

Set a Hidden (not visible) Field to the Value of Another Field

Apply class "setonsubmit-ifhidden-FIELD_ID" where FIELD_ID is the ID (not the name) of the field you want to take the value from.

Clear the Value of a Hidden (not visible) Field

To clear the value on a field-by-field basis, apply the "setonsubmit-ifhidden_clear" class to each field.  To apply it to all hidden fields in a given form use the "setonsubmit-clearhidden" field.

Disable a Hidden (not visible) Field

To disable a hidden field on submission, use the "setonsubmit-ifhidden_disable" class.  There isn't much difference between this and clearing the value.  Clearing the value will still submit the field as the key with no value.  Disabling the field will not transmit it whatsoever.

Clear the Value of Any Field on a "Return" Action

Sometimes you may want to clear the value of a field when the form is being returned (e.g., the date and signature of an approval section).  To do this on a field-by-field basis, apply the "setonsubmit-ifreturn_clear" class to each field.  To clear all fields in a given section, apply "setonsubmit-ifreturn_clear" to the <form> itself.
