Add or Edit Folder-level JavaScript

Folder level JavaScripts are JavaScript files (.JS) that are run during application startup. These can be useful for loading reusable JavaScript functions into the application, or accessing methods/properties whose security restrictions only allow them to be run in the app/init event.

Simple examples include loading the user’s Windows login into a global JavaScript variable at startup, or loading a list of employee names from your company into a JS array at startup which can be used by the forms that are opened in Nitro PDF Pro.

To add or edit a folder level JavaScript

  1. Open Nitro PDF Pro
  2. On the Forms ribbon, in the Document Setup group, click on the arrow next to JavaScript and then select Folder LevelDocument setup
  3. Add JS files to the folder or edit existing ones
