=head1 JSON Datasource

As mentioned before, the Grid expects the JSON datasource object to be of a predefined format.

  json = {

        {'fname': 

 then an Ajax request
will be sent to C</myapp/completion?search=ab>.

The server should return a JSON array, in the format explained below.

=item a callback function

That function will be called, w

 See also C<options.caseSensitive>.

=item an object (JSONP)

Useful when accessing data on a different domain via JSONP services.

  Ex :   { json_url: 'http://search.yahooapis.com/WebSearchService/V

&query=?1&output=json&callback=?2',
           json_list: 'ResultSet/Result' }

The object should hold details of the JSONP service to be called. 

C<json_url> : url to call with placeholders (?1, ?2)

type.getJSON

  Prototype.getJSON(url, callback)

based on: getJSON function by Juriy Zaytsev L<http://github.com/kangax/protolicious/tree/master/get_json.js>

A method to temporarily load JSON data (

ideally hosted on a different domain and accessible via JSONP service) and send it over to callback method when ready.
