How can I make restricted Acrobat JavaScript methods available to
users?
Many of the methods in Acrobat JavaScript are restricted for security reasons, and their
execution is only allowed during batch, console or menu events. The Acrobat JavaScript
Scripting Reference identifies these methods by a padlock symbol in the quick bar. This
restriction is a limitation when enterprise customers try to develop solutions that require
these methods and know that their environment is secure.
Three requirements must be met to make restricted Acrobat JavaScript methods available
to users.
You must obtain a digital ID.
You must sign the PDF document containing the restricted JavaScript methods using
the digital ID.
For details on where you can obtain digital IDs and the procedures for using them to
sign documents, see "Creating a certifying signature" in Adobe Acrobat 6.0 Help.
The recipient should trust the signer for certified documents and JavaScript.
For details, see "Managing digital ID certificates" in Adobe Acrobat 6.0 Help.
All trusted certificates can be accessed by selecting Certificates from Advanced > Manage
Digital IDs > Trusted Identities in Acrobat's main menu. Click Edit open and view a
certificate. To enable JavaScript execution, check the "Trusted for JavaScript" check box in
the certificate.
How can I lock a document after a signature field has been signed?
Signature fields allow the user to digitally sign a document. Once a signature is applied to
the document any subsequent changes to the document will cause the signature to
indicate that the "Document has been changed after signing".
A signature field's value is read-only. An unsigned signature has a null value. Once the field
has been signed its value is non-null. When crafting a custom script for when the signature
field is signed, remember to allow for resetting the form (i.e. the field's value is set to null).
