Doc

This object provides the interface between a PDF document open in the viewer and the JavaScript interpreter. It provides methods and properties for accessing the PDF document.

You can access the Doc object from JavaScript in a variety of ways:

•	The this object usually points to the Doc object of the underlying document.

•	Some properties and methods, such as extractPages, app.activeDocs, and app. openDoc, return the Doc object.

•	The Doc object can often be accessed through event objects, which are created for each event by which a JavaScript is executed:

•	For mouse, focus, blur, calculate, validate, and format events, event.target returns the Field object that initiated the event. You can then access the Doc object through the Doc method of the Field object.

•	For all other events, event.target points to the Doc.

Example 1: Access through this object

Use this to get the number of pages in this document:

	var nPages = this.numPages;

	// Get the crop box for "this" document:

	var aCrop = this.getPageBox();

Example 2: Access through return values

Return values from one document to open, modify, save and close another.

	// Path relative to "this" doc:

	var myDoc = app.openDoc("myNovel.pdf", this); 

	myDoc.info.Title = "My Great Novel"; 

	myDoc.saveAs(myDoc.path);

	myDoc.closeDoc(true);

Example 3: Access through the event object.

For mouse, calculate, validate, format, focus, and blur events:

	var myDoc = event.target.doc;

For all other events (for example, batch or console events):

	var myDoc = event.target;
