Overview

- * - *

Ext.Direct aims to streamline communication between the client and server - * by providing a single interface that reduces the amount of common code - * typically required to validate data and handle returned data packets - * (reading data, error conditions, etc).

- * - *

The Ext.direct namespace includes several classes for a closer integration - * with the server-side. The Ext.data namespace also includes classes for working - * with Ext.data.Stores which are backed by data from an Ext.Direct method.

- * - *

Specification

- * - *

For additional information consult the - * Ext.Direct Specification.

- * - *

Providers

- * - *

Ext.Direct uses a provider architecture, where one or more providers are - * used to transport data to and from the server. There are several providers - * that exist in the core at the moment:

- * - *

A provider does not need to be invoked directly, providers are added via - * {@link Ext.Direct}.{@link Ext.Direct#add add}.

- * - *

Router

- * - *

Ext.Direct utilizes a "router" on the server to direct requests from the client - * to the appropriate server-side method. Because the Ext.Direct API is completely - * platform-agnostic, you could completely swap out a Java based server solution - * and replace it with one that uses C# without changing the client side JavaScript - * at all.

- * - *

Server side events

- * - *

Custom events from the server may be handled by the client by adding - * listeners, for example:

- *

-{"type":"event","name":"message","data":"Successfully polled at: 11:19:30 am"}
-
-// add a handler for a 'message' event sent by the server 
-Ext.Direct.on('message', function(e){
-    out.append(String.format('<p><i>{0}</i></p>', e.data));
-            out.el.scrollTo('t', 100000, true);
-});
- *
