It is a little wonder to me how flash player communicates with JavaScript. Calls are fully synchronous, it works as those (fp and js) were fully integrated into each other. To simulate this lets test some simple flow:
Have you ever tought about accessing DOM from ActionScript? In fact, you can do it and even far more. You can create and call JavaScript methods and objects, access cookies, change styles… All you need is correct AllowScriptAccess parameter within your flash object. No framework needed here, no hacks, ExternalInterface takes care.
If your facebook iframe applications need extra permissions granted, you can use Facebook JavaScript Api to generate modal window over your content to request permissions from users. For this purpose I created a simple FB_test_perm() function. It takes 4 arguments:
You can not have a web browser inside your web flash applications right? Well, you can! This solution uses html iframe to generate fake build in browser. So the behaviour of the browser in flash is the same as the one you are previewing this flash in (it is the same one). The best part of it is, you can manipulate with the position and size of this browser directly from flash. sk.yoz.html.IFrame solution was inspired by Alistair Rutherford, www.netthreads.co.uk.
