Interacting with Server-Side ActionScript
Every
ColdFusion MX server comes with native support for server-side
ActionScript. Server-side ActionScript adds the basic functionality
of ColdFusion’s cfquery and
cfhttp tags to ActionScript. As a ColdFusion
developer, you may not have much use for server-side ActionScript;
you’ll most likely find yourself developing CFCs as
the back end for Flash Remoting applications. However, like
everything else, it’s worth understanding how
server-side ActionScript works, as you may find yourself in a
situation where it’s desirable to have a Flash
developer write the server-side code for a Flash Remoting application
as well. Having server-side ActionScript as an option makes it easier
for Flash developers to leverage the power of
cfquery and cfhttp without
having to learn ColdFusion.
Server-side ActionScript files are written just like any other
text-based file, and they can be stored anywhere on your ColdFusion
MX server under the web server’s root directory.
Server-side ActionScript files have a file extension of
.asr. In your client-side ActionScript, a
server-side ActionScript file is instantiated by referring to the
file in the gatewayConnection.getService( )
function call. Dot notation is used to point to the server-side
ActionScript file’s location. For example, to
instantiate a server-side ActionScript file called
test.asr located in
webroot/programmingcf/ch28, your client-side
ActionScript would look like this:
var myService = gatewayConnection.getService("programmingcf.ch28.test", ...Get Programming ColdFusion MX, 2nd Edition now with the O’Reilly learning platform.
