The JavaScript environment has its own Document and Window objects. JavaScript code can interact with the AIR run-time environment
through the runtime, nativeWindow, and htmlLoader properties. ActionScript code can interact with the JavaScript environment through the
window property of an HTMLLoader object, which is a reference to the JavaScript Window object. In addition, both ActionScript and JavaScript
objects can listen for events dispatched by both AIR and JavaScript objects.
The runtime property provides access to AIR API classes, allowing you to create new AIR objects as well as access class
(also called static) members. To access an AIR API, you add the name of the class, with package, to the runtime
property. For example, to create a File object, you would use the statement:
var file = new window.runtime.filesystem.File();
Note: The AIR SDK provides a JavaScript file, AIRAliases.js, that defines more convenient aliases for the most
commonly used AIR classes. When you import this file, you can use the shorter form air.Class instead of
window.runtime.package.Class. For example, you could create the File object with new air.File().
The NativeWindow object provides properties for controlling the desktop window. From within an HTML page, you
can access the containing NativeWindow object with the window.nativeWindow property.
The HTMLLoader object provides properties, methods, and events for controlling how content is loaded and
rendered. From within an HTML page, you can access the parent HTMLLoader object with the window.htmlLoader
property.
