There are a couple different places the script can be stored:
1) In an XFA form, the script is all in the XFA. You'll have to parse some XML
to get it.
2) In an AcroForm, the scripts will be in/referenced-from that field's /AA
dictionary (additional actions).
3) Additional Actions scripts can call functions stored at the document level
/Names dictionary. Within the /Names dict there can be a /Javascript entry
which will be a "Name Tree". Name tree's are arrays that act like dictionaries
but maintain a particular order to their entries. The /Names dictionary and
its kids might be indirect objects, might not. PdfDictionary & PdfArray have a
group of getAs* functions will look up indirect objects automatically for you,
returning null if the object is missing or the wrong type.

Subject: [iText-questions] Accessing Text field custom validation script
viaItext
I am trying to access a "custom validation script" created for a text field in
a PDF. I am attempting to use PDFreader to do this, but I am not having any
luck finding the script. It does not appear to be stored with the rest of the
field specific data.
Thanks,
Tim
