Function: extractAdditionalActions()

function extractAdditionalActions(
   aaDict, 
   doc, 
   context?): JavaScriptActionMap;

Defined in: src/api/PDFJavaScriptAction.ts:155

Extract JavaScript actions from an Additional Actions (AA) dictionary.

The context argument disambiguates the shared C key: pass 'field' when reading a form field's AA dictionary (so C maps to calculate) and 'page' when reading a page's AA dictionary (so C maps to pageClose). When omitted, field semantics are used together with the unambiguous page O (pageOpen) key, preserving backwards-compatible behaviour without ever mapping a single C entry to two different actions.

Parameters

Parameter	Type	Description
aaDict	PDFDict	The AA dictionary
doc	PDFDocument	The document
context?	AdditionalActionsContext	Whether the dictionary belongs to a field or a page

Returns

JavaScriptActionMap

A map of JavaScript actions
