I am fairly new to acrobat
I have designed a form that uses a JavaScript that looks at individual fields to verify if the information is good. I also require two signatures along with these correctly entered fields before I consider the form "good to go"
(If the form is missing something, my form validation JavaScript will population the value of a text box with the list of which fields are bad. The warning goes away when everything is good)
I can’t find the correct property in JavaScript that reference if the digital signature field is signed or not, so I put in the signed event JavaScript that locks the field when signed.
In my form validation script, I check to see if that digital signature field is locked- if so- then they must have signed it.
Here is where I am running into trouble:
After rights are extended to reader (my users will use reader to fill out this pdf)
It’s possible for the user to sign it, (locking the field) and then clear the digital signature (but the locked field tells my validation script its “okay”)
Locking the field does not stop someone from clearing it, which is not good.
Also, someone using reader can add a digital signature on top of where I want them to sign it- and my validation script doesn’t know about this, so it won’t remove the warning if they add their own signature.
How do I:
((Find the javascript property to know if a particular digital signature field is signed.)
OR
(Find a way to not allow the user to clear their signed signature))
AND
(Stop the user from adding their own digital signature field to the form?)
Thank you.
