Class Ext.Direct

Package:Ext
Defined In:Direct.js
Class:Direct
Extends:Observable

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 -Ext.Direct.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);
-});


This class is a singleton and cannot be created directly.
