Check out the link at the bottom of the article “Go on to Part 2″. There’s code that shows how to communicate with another SWF without any JavaScript. Part 1 was to explain the communication process.

The eval is a nice trick I’ve used before. It doesn’t make sense to use it here, since you can access the SWF directly and pass arguments, but it’s handy when you want to use Flash to manipulate the page it’s sitting on.

*correction* - it would have made more sense had I put oneLinerBridge where registeredCallback is… but you get the jist. No more javascript includes!

There is an even sweeter way to achieve this…

// in either swf
ExternalInterface.addCallback(”OneLinerBridge”, [target], oneLinerBridge);
ExternalInterface.call(”eval”, “document.getElementById(’swf_b’).registeredCallback(’var1′,’var2′)”);
