Server-Side Communication ActionScript 33

Example

The following example checks the agent property against the string "WIN" and executes different

code depending on whether they match. This code is written inside an

onConnect function.

function onConnect(newClient, name){

if (newClient.agent.indexOf("WIN") > -1){

trace ("Window user");

} else {

trace ("non Window user.agent is" + newClient.agent);

}

Client.call

Availability

Flash Communication Server MX.

Usage

Client.call(methodName, [resultObj, [p1, ..., pN]])

Parameters

methodName A method specified in the form [objectPath/]method. For example, the

command someObj/doSomething tells the client to invoke the

NetConnection.someObj.doSomething method on the client.

resultObj An optional parameter that is required when the sender expects a return value from

the client. If parameters are passed but no return value is desired, pass the value

null. The result

object can be any object you define and, in order to be useful, should have two methods that are

invoked when the result arrives:

onResult and onStatus. The resultObj.onResult event is

triggered if the invocation of the remote method is successful; otherwise, the

resultObj.onStatus event is triggered.

p1, ..., pN Optional parameters that can be of any ActionScript type, including a reference

to another ActionScript object. These parameters are passed to the

methodName parameter when

the method executes on the Flash client. If you use these optional parameters, you must pass in

some value for

resultObject; if you do not want a return value, pass null.

Returns

A Boolean value of true if a call to methodName was successful on the client; otherwise, false.

Description

Method; executes a method on the originating Flash client or on another server. The remote

method may optionally return data, which is returned as a result to the

resultObj parameter, if it

is provided. The remote object is typically a Flash client connected to the server, but it can also be

another server. Whether the remote agent is a Flash client or another server, the method is called

on the remote agent’s NetConnection object.

Example

The following example shows a client-side script that defines a function called random, which

generates a random number:

nc = new NetConnection();

nc.connect ("rtmp://someserver/someApp/someInst");

nc.random = function(){

return (Math.random());

};
