I use Prototype.js and submit an ajax request from javascript. I covert the javascript to JSON using mydata.toJSON() in the POST parameter of the AJAX request.
Back in CI i grab the _POST and json_decode() it. Go munch on the data, restructure it for the javascript and then echo json_encode() it back to the browser. The javascript will then grab the response which you can validate.
