ACTIONSCRIPT 3.0 DEVELOPER’S GUIDE
Programming HTML and JavaScript in AIR
Loading JavaScript files from outside the application installation directory
Adobe AIR 1.0 and later
Loading script files from outside the application sandbox is not permitted. No security error is generated. All script
files that run in the application sandbox must be installed in the application directory. To use external scripts in a page,
you must map the page to a different sandbox. See “Loading application content into a non-application sandbox” on
page 996.
document.write() and document.writeln()
Adobe AIR 1.0 and later
Calls to document.write() or document.writeln() are ignored after the page load event has been handled. No
security error is generated. As an alternative, you can load a new file, or replace the body of the document using DOM
manipulation techniques.
Synchronous XMLHttpRequests before the load event or during a load event
handler
Adobe AIR 1.0 and later
Synchronous XMLHttpRequests initiated before the page load event or during a load event handler do not return any
content. Asynchronous XMLHttpRequests can be initiated, but do not return until after the load event. After the load
event has been handled, synchronous XMLHttpRequests behave normally.
Dynamically created script elements
Adobe AIR 1.0 and later
Dynamically created script elements, such as when created with innerHTML or document.createElement()
method are ignored.
Accessing AIR API classes from JavaScript
Adobe AIR 1.0 and later
In addition to the standard and extended elements of Webkit, HTML and JavaScript code can access the host classes
provided by the runtime. These classes let you access the advanced features that AIR provides, including:
Access to the file system
Use of local SQL databases
Control of application and window menus
Access to sockets for networking
Use of user-defined classes and objects
Sound capabilities
