Using JQuery.serializeArray with MaskMoney Unmask

So, I'm making an AJAX call like so (this is Clojure but the problem was the same under pure JS):

(POST (str "/input/" spreadsheet "?")
                {:params        (.serializeArray (jquery (str "#" page)))
                 :format        :json
                 :handler       render-spreadsheet
                :error-handler error-handler})

The problem is that I have MaskMoney components on-screen, and they retu their formatting, so "$1,234.56" comes back as "$1,234.56" and not "1234.56".

MaskMoney has an "unmask" function that retus the raw value, but I think that requires me to re-do .serializeArray, which I'd prefer not to.

So:

1) How do I get .serializeArray and .unmask to play together?

2) If not, should I just find the .serializeArray code, and copy-and-paste it so that I can include the recalcitrant unmask call?
