Ext.data.proxy.ProxyExt.data.proxy.ServerExt.data.proxy.DirectMixins
This class is used to send requests to the server using Ext.direct. When a request is made, +the transport mechanism is handed off to the appropriate Provider +to complete the call.
+ +This proxy expects a Direct remoting method to be passed in order to be able to complete requests. +This can be done by specifying the directFn configuration. This will use the same direct +method for all requests. Alternatively, you can provide an api configuration. This +allows you to specify a different remoting method for each CRUD action.
+ +This proxy provides options to help configure which parameters will be sent to the server. +By specifying the paramsAsHash option, it will send an object literal containing each +of the passed parameters. The paramOrder option can be used to specify the order in which +the remoting method parameters are passed.
+ +Ext.define('User', {
+ extend: 'Ext.data.Model',
+ fields: ['firstName', 'lastName'],
+ proxy: {
+ type: 'direct',
+ directFn: MyApp.getUsers,
+ paramOrder: 'id' // Tells the proxy to pass the id as the first parameter to the remoting method.
+ }
+});
+User.load(1);
+The same as Ext.data.proxy.Server.api, however instead of providing urls, you should provide a direct +function call.

+True to batch actions of a particular type when synchronizing the store. +Defaults to true.
+True to batch actions of a particular type when synchronizing the store. +Defaults to true.
+Comma-separated ordering 'create', 'update' and 'destroy' actions when batching. Override this +to set a different order for the batched CRUD actions to be executed in. Defaults to 'create,update,destroy'
+The name of the cache param added to the url when using noCache (defaults to "_dc")
+The name of the cache param added to the url when using noCache (defaults to "_dc")
+Function to call when executing a request. directFn is a simple alternative to defining the api configuration-parameter +for Store's which will not implement a full CRUD api.
+The name of the direction parameter to send in a request. This is only used when simpleSortMode is set to true. +Defaults to 'dir'.
+Extra parameters that will be included on every read request. Individual requests with params +of the same name will override these params when they are in conflict.
+The name of the 'filter' parameter to send in a request. Defaults to 'filter'. Set +this to undefined if you don't want to send a filter parameter
+The name of the 'group' parameter to send in a request. Defaults to 'group'. Set this +to undefined if you don't want to send a group parameter
+The name of the 'limit' parameter to send in a request. Defaults to 'limit'. Set this +to undefined if you don't want to send a limit parameter
+(optional)
A config object containing one or more event handlers to be added to this +object during initialization. This should be a valid listeners config object as specified in the +addListener example for attaching multiple handlers at once.
+ +DOM events from ExtJs Components
+ + +While some ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this + + +
is usually only done when extra value can be added. For example the DataView's
+click event passing the node clicked on. To access DOM
+events directly from a child element of a Component, we need to specify the element option to
+identify the Component property to add a DOM listener to:
new Ext.panel.Panel({
+ width: 400,
+ height: 200,
+ dockedItems: [{
+ xtype: 'toolbar'
+ }],
+ listeners: {
+ click: {
+ element: 'el', //bind to the underlying el property on the panel
+ fn: function(){ console.log('click el'); }
+ },
+ dblclick: {
+ element: 'body', //bind to the underlying body property on the panel
+ fn: function(){ console.log('dblclick body'); }
+ }
+ }
+});
+The name of the Model to tie to this Proxy. Can be either the string name of +the Model, or a reference to the Model constructor. Required.
+(optional) Defaults to true. Disable caching by adding a unique parameter +name to the request.
+(optional) Defaults to true. Disable caching by adding a unique parameter +name to the request.
+The name of the 'page' parameter to send in a request. Defaults to 'page'. Set this to +undefined if you don't want to send a page parameter
+Defaults to undefined. A list of params to be executed +server side. Specify the params in the order in which they must be executed on the server-side +as either (1) an Array of String values, or (2) a String of params delimited by either whitespace, +comma, or pipe. For example, +any of the following would be acceptable:
+ +paramOrder: ['param1','param2','param3']
+paramOrder: 'param1 param2 param3'
+paramOrder: 'param1,param2,param3'
+paramOrder: 'param1|param2|param'
+ Send parameters as a collection of named arguments (defaults to true). Providing a +paramOrder nullifies this configuration.
+The Ext.data.reader.Reader to use to decode the server's response. This can +either be a Reader instance, a config object or just a valid Reader type name (e.g. 'json', 'xml').
+Enabling simpleSortMode in conjunction with remoteSort will only send one sort property and a direction when a remote sort is requested. +The directionParam and sortParam will be sent with the property name and either 'ASC' or 'DESC'
+The name of the 'sort' parameter to send in a request. Defaults to 'sort'. Set this +to undefined if you don't want to send a sort parameter
+The name of the 'start' parameter to send in a request. Defaults to 'start'. Set this +to undefined if you don't want to send a start parameter
+(optional) The number of milliseconds to wait for a response. Defaults to 30 seconds.
+(optional) The number of milliseconds to wait for a response. Defaults to 30 seconds.
+The Ext.data.writer.Writer to use to encode any request sent to the server. +This can either be a Writer instance, a config object or just a valid Writer type name (e.g. 'json', 'xml').

this reference) in which the handler function is executed.
+If 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 +will exist only after the Component is rendered. For example, to add a click listener to a Panel's body: +
new Ext.panel.Panel({
+ title: 'The title',
+ listeners: {
+ click: this.handlePanelClick,
+ element: 'body'
+ }
+});
+When added in this way, the options available are the options applicable to Ext.core.Element.addListener
+ + +
+Combining Options
+Using the options argument, it is possible to combine different types of listeners:
+
+A delayed, one-time listener.
+
myPanel.on('hide', this.handleClick, this, {
+single: true,
+delay: 100
+});
+Attaching multiple handlers in 1 call
+The method also allows for a single argument to be passed which is a config object containing properties
+which specify multiple events. For example:
+
myGridPanel.on({
+ cellClick: this.onCellClick,
+ mouseover: this.onMouseOver,
+ mouseout: this.onMouseOut,
+ scope: this // Important. Ensure "this" is correct during handler execution
+});

Performs a batch of Operations, in the order specified by batchOrder. Used internally by +Ext.data.Store's sync method. Example usage:
+ +myProxy.batch({
+ create : [myModel1, myModel2],
+ update : [myModel3],
+ destroy: [myModel4, myModel5]
+});
+Where the myModel* above are Model instances - in this case 1 and 2 are new instances and have not been +saved before, 3 has been saved previously but needs to be updated, and 4 and 5 have already been saved but should now be destroyed.
+Object containing the Model instances to act upon, keyed by action name
+Optional listeners object passed straight through to the Batch - see Ext.data.Batch
+The newly created Ext.data.Batch object
+Creates and returns an Ext.data.Request object based on the options passed by the Store +that this Proxy is attached to.

+In ServerProxy subclasses, the create, read, update and destroy methods all pass +through to doRequest. Each ServerProxy subclass must implement the doRequest method - see Ext.data.proxy.JsonP +and Ext.data.proxy.Ajax for examples. This method carries the same signature as each of the methods that delegate to it.
+The Ext.data.Operation object
+The callback function to call when the Operation has completed
+The scope in which to execute the callback
+Enables events fired by this Observable to bubble up an owner hierarchy by calling
+this.getBubbleTarget() if present. There is no implementation in the Observable base class.
This is commonly used by Ext.Components to bubble events to owner Containers. See Ext.Component.getBubbleTarget. The default +implementation in Ext.Component returns the Component's immediate owner. But if a known target is required, this can be overridden to +access the required target more quickly.
+ + +Example:
+ + +Ext.override(Ext.form.field.Base, {
+// Add functionality to Field's initComponent to enable the change event to bubble
+initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
+ this.enableBubble('change');
+}),
+
+// We know that we want Field's events to bubble directly to the FormPanel.
+getBubbleTarget : function() {
+ if (!this.formPanel) {
+ this.formPanel = this.findParentByType('form');
+ }
+ return this.formPanel;
+}
+});
+
+var myForm = new Ext.formPanel({
+title: 'User Details',
+items: [{
+ ...
+}],
+listeners: {
+ change: function() {
+ // Title goes red if form has been modified.
+ myForm.header.setStyle('color', 'red');
+ }
+}
+});
