Remove Field Action

PDF forms often contain JavaScript actions that execute when users interact with form elements such as buttons or input fields. In some cases, these scripts must be removed to simplify form behavior, improve security, or update the form logic. Remove a JavaScript action from a form field in a PDF document using Aspose.PDF for Python. The code opens an existing PDF form, locates a specific field, removes its associated JavaScript action, and saves the updated document as a new PDF file.

Using the FormEditor class from the aspose.pdf.facades, you can remove JavaScript actions from specific fields in an existing PDF form:

1. Open an existing PDF form.
2. Locate a form field named ‘Script_Demo_Button’.
3. Remove the JavaScript action associated with that field.
4. Check whether the removal was successful.
5. Save the updated PDF document.

import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades
import sys
from os import path

sys.path.append(path.join(path.dirname(__file__), ".."))

from config import set_license, initialize_data_dir


def remove_field_script(input_file_name, output_file_name):
    # Create FormEditor object
    form_editor = pdf_facades.FormEditor()

    # Open input PDF file
    form_editor.bind_pdf(input_file_name)

    # Remove JavaScript action from the field
    if not form_editor.remove_field_action("Script_Demo_Button"):
        raise Exception("Failed to remove field script")

    # Save output PDF file
    form_editor.save(output_file_name)
