660 Chapter 30: Using Server-Side ActionScript
These functions are available for every RecordSet object returned by the
CF.query
function to the
Flash MX client. You invoke these functions as follows:
objectName.functionName();
For example, in the result function that you create to handle record set data returned by the
CF.query
function, you can reference the database column names returned in the record set using
the
getColumnNames
RecordSet function:
function selectData_Result ( result )
{
//result holds the query data; employeesView is a Flash list box
stringOutput.text = result.getColumnNames();
_root.employeesView.setDataProvider(result);
}
Building a simple application
The following procedure describes how to build a simple server-side ActionScript application.
The example application, a corporate personnel directory, uses the NetServices object to connect
to the
personneldirectory
server-side ActionScript. The
personneldirectory
server-side
ActionScript retrieves data from a ColdFusion MX data source and returns the results to the Flash
movie as a RecordSet object.
Note: The server-side ActionScript application that you create provides the back-end services in an
application.
This example requires the following:
•
A server-side ActionScript file named personneldirectory.asr that includes functions that
interact with a ColdFusion MX data source.
•
A client-side Flash MX movie in which the NetServices object is created.
To create the application:
1
Write server-side ActionScript that performs the database query and returns data to the client
through the Flash Remoting service.
2
Create the Flash movie interface. See “Creating the Flash movie interface” on page 661 .
3
Define a search function that sends user data to the Flash Remoting service. See “Submitting
user data to the Flash Remoting service” on page 662 .
4
Define a result function that captures the results returned from the Flash Remoting service. See
“” on page 662 .
5
Ensure that the Flash movie has established a connection to the Flash Remoting service. See
“Checking for a Flash Remoting service connection” on page 663 .
