Client-Side Communication ActionScript 37

Parameters

connectionName A string that corresponds to the connection name specified in the

LocalConnection.connect command that wants to communicate with sendingLC.

method A string specifying the name of the method to be invoked in the receiving

LocalConnection object. The following method names cause the command to fail:

send,

connect, close, domain, onStatus, and allowDomain.

p1,...pN Optional parameters to be passed to the specified method.

Returns

A Boolean value of true if Flash can carry out the request, false otherwise.

Note: A return value of true does not necessarily mean that Flash successfully connected to a receiving

LocalConnection object, only that the command is syntactically correct. To determine whether the connection

succeeded, see LocalConnection.onStatus.

Description

Method; invokes the method named method on a connection opened with the

LocalConnection.connect(connectionName) command (called the receiving LocalConnection

object). The object used with this command is called the sending LocalConnection object.

The movies that contain the sending and receiving objects must be running on the same

client machine.

There is a limit to the amount of data you can pass as parameters to this command. If the

command returns

false but your syntax is correct, try breaking up the LocalConnection.send

requests into multiple commands.

As discussed in

LocalConnection.connect, Flash adds the current subdomain to

connectionName by default. If you are implementing communication between different

domains, you need to define

connectionName in both the sending and receiving

LocalConnection objects in such a way that Flash does not add the current subdomain to

connectionName. There are two ways you can do so:

• Use an underscore (_) at the beginning of connectionName in both the sending and

receiving LocalConnection objects. In the movie containing the receiving object, use

LocalConnection.allowDomain to specify that connections from any domain will be

accepted. This implementation lets you store your sending and receiving movies in

any domain.

• Include the subdomain in connectionName in the sending LocalConnection object—for

example,

myDomain.com:myConnectionName. In the receiving object, use

LocalConnection.allowDomain to specify that connections from the specified subdomain

will be accepted (in this case, myDomain.com), or that connections from any domain will

be accepted.

Note: You cannot specify a subdomain in connectionName in the receiving LocalConnection object, only in the

sending LocalConnection object.

Example

For an example of communicating between LocalConnection objects located in the same domain,

see

LocalConnection.connect. For an example of communicating between LocalConnection

objects located in any domain, see

LocalConnection.allowDomain. For an example of

communicating between LocalConnection objects located in specified domains, see

LocalConnection.allowDomain and LocalConnection.domain.
