The Flash Document Object Model

The Flash Document Object Model (DOM) for the Flash JavaScript API consists of a set of top-level functions (see

“Top-Level Functions and Methods” on page 14) and two top-level objects—the FLfile object and the flash object (fl).

Each object is guaranteed to be available to a script because it always exists when the Flash authoring environment is

open. For more information, see

FLfile object and flash object (fl).

When referring to the flash object, you can use flash or fl. For example, to close all open FLA files, you can use either

of the following statements:

flash.closeAll();

fl.closeAll();

The flash object contains the following child objects:

The Document object

An important property of the top-level flash object is the fl.documents property. This property contains an array of

Document objects, each of which represents one of the FLA files currently open in the authoring environment. The

properties of each Document object represent most of the elements that a FLA file can contain. Therefore, a large

portion of the DOM is composed of child objects and properties of the Document object. For more information, see

Document object.

To refer to the first open document, for example, use the statement flash.documents[0] or fl.documents[0]. The

first document is the first Flash document that was opened during the current session in the authoring environment.

When the first opened document is closed, the indexes of the other open documents are decremented.

To find a particular document’s index, use flash.findDocumentIndex(nameOfDocument) or

fl.findDocumentIndex(nameOfDocument). See fl.findDocumentIndex().

Object How to access

actionsPanel object Use fl.actionsPanel to access the actionsPanel object. This object corresponds to the Actions

panel in the Flash authoring environment.

compilerErrors object Use fl.compilerErrors to access the compilerErrors object. This object corresponds to the

Compiler Errors panel in the Flash authoring environment.

componentsPanel object Use fl.componentsPanel to access the componentsPanel object. This object corresponds to the

Components panel in the Flash authoring environment.

Document object Use fl.documents to retrieve an array of all the open documents; use fl.documents[index] to

access a particular document; use

fl.getDocumentDOM() to access the current document (the one

with focus).

drawingLayer object Use fl.drawingLayer to access the drawingLayer object.

Math object Use fl.Math to access the Math object.

outputPanel object Use fl.outputPanel to access the outputPanel object. This object corresponds to the Output panel

in the Flash authoring environment.

presetPanel object Use fl.presetPanel to access the presetPanel object. This object corresponds to the Motion Presets

panel (Window

> Motion Presets).

swfPanel object Use fl.swfPanels to access an array of swfPanel objects. These objects correspond to Window SWF

panels.

Tools object Use fl.tools to access an array of Tools objects.

XMLUI object Use fl.xmlui to access an XML User Interface (XMLUI) object. The XMLUI object provides the ability

to get and set properties of an XMLUI dialog box.
