Overview
\n\n\n\n\nExt.Direct aims to streamline communication between the client and server\nby providing a single interface that reduces the amount of common code\ntypically required to validate data and handle returned data packets\n(reading data, error conditions, etc).
\n\n\n\n\nThe Ext.direct namespace includes several classes for a closer integration\nwith the server-side. The Ext.data namespace also includes classes for working\nwith Ext.data.Stores which are backed by data from an Ext.Direct method.
\n\n\n\n\nSpecification
\n\n\n\n\nFor additional information consult the\nExt.Direct Specification.
\n\n\n\n\nProviders
\n\n\n\n\nExt.Direct uses a provider architecture, where one or more providers are\nused to transport data to and from the server. There are several providers\nthat exist in the core at the moment:
\n\n\nA provider does not need to be invoked directly, providers are added via\nExt.direct.Manager.add.
\n\n\n\n\nRouter
\n\n\n\n\nExt.Direct utilizes a \"router\" on the server to direct requests from the client\nto the appropriate server-side method. Because the Ext.Direct API is completely\nplatform-agnostic, you could completely swap out a Java based server solution\nand replace it with one that uses C# without changing the client side JavaScript\nat all.
\n\n\n\n\nServer side events
\n\n\n\n\nCustom events from the server may be handled by the client by adding\nlisteners, for example:
\n\n\n{\"type\":\"event\",\"name\":\"message\",\"data\":\"Successfully polled at: 11:19:30 am\"}\n\n// add a handler for a 'message' event sent by the server\nExt.direct.Manager.on('message', function(e){\n out.append(String.format('<p><i>{0}</i></p>', e.data));\n out.el.scrollTo('t', 100000, true);\n});\n(optional)
A config object containing one or more event handlers to be added to this\nobject during initialization. This should be a valid listeners config object as specified in the\naddListener example for attaching multiple handlers at once.
\n\nDOM events from ExtJs Components
\n\n\nWhile some ExtJs Component classes export selected DOM events (e.g. \"click\", \"mouseover\" etc), this\n\n\n
is usually only done when extra value can be added. For example the DataView's\nclick event passing the node clicked on. To access DOM\nevents directly from a child element of a Component, we need to specify the element option to\nidentify the Component property to add a DOM listener to:
new Ext.panel.Panel({\n width: 400,\n height: 200,\n dockedItems: [{\n xtype: 'toolbar'\n }],\n listeners: {\n click: {\n element: 'el', //bind to the underlying el property on the panel\n fn: function(){ console.log('click el'); }\n },\n dblclick: {\n element: 'body', //bind to the underlying body property on the panel\n fn: function(){ console.log('dblclick body'); }\n }\n }\n});\nAdds the specified events to the list of events which this Observable may fire.
\n", + "params": [ + { + "type": "Object/String", + "name": "o", + "doc": "Either an object with event names as properties with a value of true\nor the first event name string if multiple event names are being passed as separate parameters.
[additional] Optional additional event names if multiple event names are being passed as separate parameters.\nUsage:

this reference) in which the handler function is executed.\nIf omitted, defaults to the object which fired the event.This option is useful during Component construction to add DOM event listeners to elements of Components which\nwill exist only after the Component is rendered. For example, to add a click listener to a Panel's body:\n
new Ext.panel.Panel({\n title: 'The title',\n listeners: {\n click: this.handlePanelClick,\n element: 'body'\n }\n});\nWhen added in this way, the options available are the options applicable to Ext.core.Element.addListener
\n\n\n\nCombining Options
\nUsing the options argument, it is possible to combine different types of listeners:
\n
\nA delayed, one-time listener.\n
myPanel.on('hide', this.handleClick, this, {\nsingle: true,\ndelay: 100\n});\nAttaching multiple handlers in 1 call
\nThe method also allows for a single argument to be passed which is a config object containing properties\nwhich specify multiple events. For example:\n
myGridPanel.on({\n cellClick: this.onCellClick,\n mouseover: this.onMouseOver,\n mouseout: this.onMouseOut,\n scope: this // Important. Ensure \"this\" is correct during handler execution\n});\n\n\n", + "optional": true + } + ], + "return": { + "type": "void", + "doc": "\n" + }, + "private": false, + "static": false, + "filename": "/Users/nick/Projects/sencha/SDK/platform/src/util/Observable.js", + "linenr": 271, + "html_filename": "Observable.html", + "href": "Observable.html#Ext-util-Observable-method-addListener", + "shortDoc": "
