Sets default values for jQuery’s Ajax options. Passes the same kind of options object you would pass to jQuery.ajax(). The values you specify will be used by any subsequent Ajax request that does not specify the value itself. This function has no return value.

jQuery.getJSON(url, [data], [f(object,status)]):XHR

Asynchronously requests the specified url, adding any data that is specified. When the response is received, parses it as JSON, and passes the resulting object to the callback ...
