Document JavaScripts are variable and function definitions that are generally useful to a given document, but are not applicable outside the document.
- Variable definitions: Define variables at the document level to make them visible to any executing script.
- Function definitions: Define functions at the document level that support the user interaction with the document. These functions may be utility functions for handling common tasks for string or number manipulation, or functions that execute lengthy scripts called by actions initiated by a user interacting with form fields, bookmarks, page changes, etc.
To create or access document level scripts in Foxit PDF Editor, select Form > JavaScript > Document JavaScript.
