Question

I have a swf hosted at domain A, and I have a html at domain B

My swf is able to be loaded from accessing the html at domain B.
However, the swf gets a

SecurityError: Error #2060: Security sandbox violation:
ExternalInterface caller http://domainA.com/TrialApp.swf cannot access
http://DomainB.com/.

The as3 is just the below:

ExternalInterface.call("javascript:_invite();");

I’ve also loaded the crossdomain policy file from Domain B during initialization.

Security.loadPolicyFile( "http://DomainB/crossdomain.xml" );

How do I go about solving this?

in my html, I have

allowscriptaccess='always'

Thanks in Advance

Jacob is right, you are not supposed to include the javascript protocol when using ExternalInterface.call().

I am far from certain that it will solve the security exception, but you could try to do:

ExternalInterface.call("_invite");

… instead of:

ExternalInterface.call("javascript:_invite();");

The documented way to use ExternalInterface.call() is ExternalInterface.call(functionName:String, … arguments). In practice, you can also send a string that is a piece of JavaScript (without “javascript:”), and it will be executed, so ExternalInterface.call(“_invite();”) could also work.
