Can't seem to get it to work.  Have tried posting to a .Net Mvc 4 action, 
and a Ruby/Rails action.  Have had no success at all. It attempts and then 
just throws an exception:

"SYNTAX_ERR: DOM Exception 12"
"Error: An invalid or illegal string was specified."

Problem is, that doesn't really help much. I've tried creating an object 
from form data manually. Tried using cloSure to create the needed form 
data. Tried serializing both. ect. Really new to clojurescript and cloSure, 
so I'm hoping it's something really simple. Just can't find any examples 
that work that don't involve a clojure based framework.


(defn get-form-action [formName]
  (let [form (dom/$ formName)]
  form/action))

(defn callback [reply] 
  (js/alert reply))

(defn ajax-json [formName]
  (let [action         (str (get-form-action formName) ".json")
        formData     (.toObject (.getFormDataMap goog.dom.forms (dom/$ 
formName)))
        serialized    (goog.json.serialize formData)]
        (.send goog.net.XhrIo action callback  'POST' serialized )))
