CentralDispatch

CentralDispatch is a totally awesome replacement for JSONP. It pushes the
callback matching work to the client, but allows for server side caching of JSON
data. This is a huge benefit if you’re aggressively caching your application.

Client Side Usage

CentralDispatch.requestData(url, callback, options)

Parameters

param	expected type	description
url	String	The url from which you’re fetching data
callback	Function or Hash	A function that will be called when the data is received, or a hash described below

Options Hash:
| key | expected type | description |
| onSuccess | Function | A function to be called when the data is received |
| onError | Function | A function to be called if there is an error fetching the data |

Example

var callback = function (data) {
    alert(data);
};
CentralDispatch.requestData('http://trottercashion.com/examples/cdData.js', callback)

var errorCallback = function (msg, url, line) {
    alert("error: " + msg);
}

Server Side Usage

On the server, all JSON data must be wrapped in CentralDispatch.receiveData,
which is described below.

CentralDispatch.receiveData(version, url, data)

Parameters

param	expected type	description
version	String	The version of CentralDispatch.receiveData you’re using, currently only v1
url	String	The url where the data resides, can be a path fragment
data	JSON	The JSON data

Examples

CentralDispatch.receiveData('v1', 'http://trottercashion.com/examples/cdData.js', {foo: bar});
CentralDispatch.receiveData('v1', 'examples/cdData.js', {foo: 'bar'});
