ExternalInterface could be your friend :

or

(I'm not sure the second link will work, though ... )

So from actionscript to javscript and vice versa, using ExternalInterface only. am i correct?

Yes, you can either call a function declared in JS from AS, or register an AS function so that it can be called by JS.

By the way, ExternalInterface communicates using XML-encoded objects, not JSON. The encoding/decoding is done behind the scenes, transparent to your use, but the calls could take a long time if it has to encode a complex object in XML.
You can call a function inside your Flash with the following Javascript:
<script>
function callToFlash(param)
{
var fl = document.getElementById('idOfFlashObject');
if(fl != null)
{
fl.functionInFlash(param);
}
}
</script>

You have to register the function (using ExternalInterface.addCallback) in Flash first before it can be called from JavaScript.
