LocalConnection.allowDomain

Availability

• Flash Player 6.

• Flash Communication Server MX (not required).

Usage

receivingLC.allowDomain = function([sendingDomain]) {

// Your code here returns true or false

}

Parameters

sendingDomain An optional parameter specifying the subdomain of the movie containing the

sending LocalConnection object.

Returns

Nothing.

Description

Event handler; invoked whenever receivingLC receives a request to invoke a method from a

sending LocalConnection object. Flash expects the code you implement in this handler to return

a Boolean value of

true or false. If the handler doesn’t return true, the request from the

sending object is ignored, and the method is not invoked.

Use this command to explicitly permit LocalConnection objects from specified domains, or from

any domain, to execute methods of the receiving LocalConnection object. If you don’t pass a

value for

sendingDomain, you probably want to accept commands from any domain, and the

code in your handler would simply be

return true. If you do pass a value for sendingDomain,

you probably want to compare the value of

sendingDomain with domains from which you want

to accept commands. Both of these implementations are illustrated in the following examples.

Example

The following example shows how a LocalConnection object in a receiving movie can permit

movies from any domain to invoke its methods. Compare this to the example in

LocalConnection.connect, in which only movies from the same domain can invoke the Trace

method in the receiving movie. For a discussion of the use of the underscore (_) in the connection

name, see

LocalConnection.send.

var aLocalConnection = new LocalConnection();

aLocalConnection.Trace = function(aString)

{

aTextField = aTextField + aString + newline;

}

aLocalConnection.allowDomain = function() {

// any domain can invoke methods on this LocalConnection object

return true;

}

aLocalConnection.connect("_trace");
