// The search() method is defined in the server-side AS file

}
Reviewing the code
The following table describes the code and its function:
Capturing Flash Remoting service results
When you create a function that calls a server-side ActionScript function, also create a function to handle the data
returned by server-side ActionScript. Define the function with the same name as the function making the initial call,
but you append
_Result
to the name.
For example, if you create a function called
basicQuery
to return query data, you define a results function to handle
returned data; declare the results function as
basicQuery_Result
.
In the following example, the results function
search_Result
supplies the record set to the
dataView.setDataProvider
function:
function search_Result(resultset)
{
dataView.setDataProvider(resultset);
status.text = (0+resultset.getLength())+" names found.";
}
Reviewing the code
The following table describes the code and its function:
Code
Description
directoryService.search
(firstName.text, lastName.text);
Passes the contents of the firstName and lastName text boxes to server-side
ActionScript.
dataView.setDataProvider
(null);
Clears the
dataView
list box component.
status.text = "waiting...";
Displays a message in the status text box while the record set is being
retrieved from server-side ActionScript.
Code
Description
function search_Result
(resultset)
The
_Result
suffix tells the Flash Remoting service to return the results of
the search function to this function.
dataView.setDataProvider
(resultset);
Assigns the results returned by the Flash Remoting service to the
dataView
list box.
status.text = (0+resultset.
getLength())+" names found.";
Displays the number of records returned by the Flash Remoting service.
