Adobe E-Sign - Javascript to hide/show fields not working when sending out e-sign

Hi @brandon_9880,

Thank you for reaching out. 

• Acrobat e-sign converts the PDF into a web-based signing experience, which does not support PDF JavaScript.

• When a document is sent for signature through e-sign, it is uploaded, parsed, and re-rendered as a static web form, so all JavaScript logic is lost.

• Only basic field properties (like required, read-only, and default values) survive.

You can try:

1. Avoid JavaScript if sending via Acrobat Sign

• Instead, use conditional visibility via Acrobat Sign’s built-in rules (via the Adobe Sign Authoring tool, available on the web interface).

• You can pre-define visibility conditions using field templates or logic-based visibility rules in Adobe Sign.

2. Send via Regular Email (Not e-signature workflow)

• If you need the full JavaScript behavior, share the PDF directly via email or cloud, and let users open it in Adobe Acrobat Reader (desktop).

• In this case, the JavaScript will work as expected.

3. Use Adobe Acrobat JavaScript only for static forms

• Keep dynamic functionality for internal workflows where the file doesn’t go through Acrobat Sign.

Let us know if you have further questions.
