JsonPProxy is useful when you need to load data from a domain other than the one your application is running\non. If your application is running on http://domainA.com it cannot use Ajax to load its\ndata from http://domainB.com because cross-domain ajax requests are prohibited by the browser.
\n\n\n\n\nWe can get around this using a JsonPProxy. JsonPProxy injects a <script> tag into the DOM whenever\nan AJAX request would usually be made. Let's say we want to load data from http://domainB.com/users - the script tag\nthat would be injected might look like this:
\n\n\n\n\n<script src=\"http://domainB.com/users?callback=someCallback\"></script>\nWhen we inject the tag above, the browser makes a request to that url and includes the response as if it was any\nother type of JavaScript include. By passing a callback in the url above, we're telling domainB's server that we\nwant to be notified when the result comes in and that it should call our callback function with the data it sends\nback. So long as the server formats the response to look like this, everything will work:
\n\n\n\n\nsomeCallback({\n users: [\n {\n id: 1,\n name: \"Ed Spencer\",\n email: \"ed@sencha.com\"\n }\n ]\n});\nAs soon as the script finishes loading, the 'someCallback' function that we passed in the url is called with the\nJSON object that the server returned.
\n\n\n\n\nJsonPProxy takes care of all of this automatically. It formats the url you pass, adding the callback\nparameter automatically. It even creates a temporary callback function, waits for it to be called and then puts\nthe data into the Proxy making it look just like you loaded it through a normal AjaxProxy.\nHere's how we might set that up:
\n\n\n\n\nExt.define('User', {\n extend: 'Ext.data.Model',\n fields: ['id', 'name', 'email']\n});\n\nvar store = new Ext.data.Store({\n model: 'User',\n proxy: {\n type: 'jsonp',\n url : 'http://domainB.com/users'\n }\n});\n\nstore.load();\nThat's all we need to do - JsonPProxy takes care of the rest. In this case the Proxy will have injected a\nscript tag like this:\n\n
<script src=\"http://domainB.com/users?callback=stcCallback001\" id=\"stcScript001\"></script>\nCustomization
\n\nMost parts of this script tag can be customized using the callbackParam, callbackPrefix and\nscriptIdPrefix configurations. For example:\n\n
var store = new Ext.data.Store({\n model: 'User',\n proxy: {\n type: 'jsonp',\n url : 'http://domainB.com/users',\n callbackParam: 'theCallbackFunction',\n callbackPrefix: 'ABC',\n scriptIdPrefix: 'injectedScript'\n }\n});\n\nstore.load();\nWould inject a script tag like this:
\n\n<script src=\"http://domainB.com/users?theCallbackFunction=ABC001\" id=\"injectedScript001\"></script>\nImplementing on the server side
\n\nThe remote server side needs to be configured to return data in this format. Here are suggestions for how you\nmight achieve this using Java, PHP and ASP.net:
\n\nJava:
\n\nboolean jsonP = false;\nString cb = request.getParameter(\"callback\");\nif (cb != null) {\n jsonP = true;\n response.setContentType(\"text/javascript\");\n} else {\n response.setContentType(\"application/x-json\");\n}\nWriter out = response.getWriter();\nif (jsonP) {\n out.write(cb + \"(\");\n}\nout.print(dataBlock.toJsonString());\nif (jsonP) {\n out.write(\");\");\n}\nPHP:
\n\n$callback = $_REQUEST['callback'];\n\n// Create the output object.\n$output = array('a' => 'Apple', 'b' => 'Banana');\n\n//start output\nif ($callback) {\n header('Content-Type: text/javascript');\n echo $callback . '(' . json_encode($output) . ');';\n} else {\n header('Content-Type: application/x-json');\n echo json_encode($output);\n}\nASP.net:
\n\nString jsonString = \"{success: true}\";\nString cb = Request.Params.Get(\"callback\");\nString responseString = \"\";\nif (!String.IsNullOrEmpty(cb)) {\n responseString = cb + \"(\" + jsonString + \")\";\n} else {\n responseString = jsonString;\n}\nResponse.Write(responseString);\nSpecific urls to call on CRUD action methods \"read\", \"create\", \"update\" and \"destroy\".\nDefaults to:
\n\napi: {\n read : undefined,\n create : undefined,\n update : undefined,\n destroy : undefined\n}\nThe url is built based upon the action being executed [load|create|save|destroy]\nusing the commensurate api property, or if undefined default to the\nconfigured Ext.data.Store.url.
\n\n\nFor example:
\n\n\napi: {\n load : '/controller/load',\n create : '/controller/new',\n save : '/controller/update',\n destroy : '/controller/destroy_action'\n}\nIf the specific URL for a given CRUD action is undefined, the CRUD action request\nwill be directed to the configured url.

The JsonP proxy is useful when you need to load data from a domain other than the one your application is running on. If\nyour application is running on http://domainA.com it cannot use Ajax to load its data\nfrom http://domainB.com because cross-domain ajax requests are prohibited by the browser.
\n\nWe can get around this using a JsonP proxy. JsonP proxy injects a <script> tag into the DOM whenever an AJAX request\nwould usually be made. Let's say we want to load data from http://domainB.com/users - the script tag that would be\ninjected might look like this:
<script src=\"http://domainB.com/users?callback=someCallback\"></script>\nWhen we inject the tag above, the browser makes a request to that url and includes the response as if it was any\nother type of JavaScript include. By passing a callback in the url above, we're telling domainB's server that we want\nto be notified when the result comes in and that it should call our callback function with the data it sends back. So\nlong as the server formats the response to look like this, everything will work:
\n\nsomeCallback({\n users: [\n {\n id: 1,\n name: \"Ed Spencer\",\n email: \"ed@sencha.com\"\n }\n ]\n});\nAs soon as the script finishes loading, the 'someCallback' function that we passed in the url is called with the JSON\nobject that the server returned.
\n\nJsonP proxy takes care of all of this automatically. It formats the url you pass, adding the callback parameter\nautomatically. It even creates a temporary callback function, waits for it to be called and then puts the data into\nthe Proxy making it look just like you loaded it through a normal AjaxProxy. Here's how\nwe might set that up:
\n\nExt.define('User', {\n extend: 'Ext.data.Model',\n fields: ['id', 'name', 'email']\n});\n\nvar store = Ext.create('Ext.data.Store', {\n model: 'User',\n proxy: {\n type: 'jsonp',\n url : 'http://domainB.com/users'\n }\n});\n\nstore.load();\nThat's all we need to do - JsonP proxy takes care of the rest. In this case the Proxy will have injected a script tag\nlike this:
\n\n<script src=\"http://domainB.com/users?callback=callback1\"></script>\nThis script tag can be customized using the callbackKey configuration. For example:
\n\nvar store = Ext.create('Ext.data.Store', {\n model: 'User',\n proxy: {\n type: 'jsonp',\n url : 'http://domainB.com/users',\n callbackKey: 'theCallbackFunction'\n }\n});\n\nstore.load();\nWould inject a script tag like this:
\n\n<script src=\"http://domainB.com/users?theCallbackFunction=callback1\"></script>\nThe remote server side needs to be configured to return data in this format. Here are suggestions for how you might\nachieve this using Java, PHP and ASP.net:
\n\nJava:
\n\nboolean jsonP = false;\nString cb = request.getParameter(\"callback\");\nif (cb != null) {\n jsonP = true;\n response.setContentType(\"text/javascript\");\n} else {\n response.setContentType(\"application/x-json\");\n}\nWriter out = response.getWriter();\nif (jsonP) {\n out.write(cb + \"(\");\n}\nout.print(dataBlock.toJsonString());\nif (jsonP) {\n out.write(\");\");\n}\nPHP:
\n\n$callback = $_REQUEST['callback'];\n\n// Create the output object.\n$output = array('a' => 'Apple', 'b' => 'Banana');\n\n//start output\nif ($callback) {\n header('Content-Type: text/javascript');\n echo $callback . '(' . json_encode($output) . ');';\n} else {\n header('Content-Type: application/x-json');\n echo json_encode($output);\n}\nASP.net:
\n\nString jsonString = \"{success: true}\";\nString cb = Request.Params.Get(\"callback\");\nString responseString = \"\";\nif (!String.IsNullOrEmpty(cb)) {\n responseString = cb + \"(\" + jsonString + \")\";\n} else {\n responseString = jsonString;\n}\nResponse.Write(responseString);\nSpecific urls to call on CRUD action methods \"create\", \"read\", \"update\" and \"destroy\". Defaults to:
\n\napi: {\n create : undefined,\n read : undefined,\n update : undefined,\n destroy : undefined\n}\nThe url is built based upon the action being executed [create|read|update|destroy] using the commensurate\napi property, or if undefined default to the configured\nExt.data.Store.url.
\n\nFor example:
\n\napi: {\n create : '/controller/new',\n read : '/controller/load',\n update : '/controller/update',\n destroy : '/controller/destroy_action'\n}\nIf the specific URL for a given CRUD action is undefined, the CRUD action request will be directed to the\nconfigured url.
\nTrue to automatically append the request's params to the generated url. Defaults to true
\nDefaults to: true
True to batch actions of a particular type when synchronizing the store. Defaults to true.
\nDefaults to: true
Comma-separated ordering 'create', 'update' and 'destroy' actions when batching. Override this to set a different\norder for the batched CRUD actions to be executed in. Defaults to 'create,update,destroy'.
\nDefaults to: "create,update,destroy"
The name of the cache param added to the url when using noCache. Defaults to \"_dc\".
\nDefaults to: "_dc"
See Ext.data.JsonP.callbackKey.
\nDefaults to: "callback"
The name of the direction parameter to send in a request. This is only used when simpleSortMode is set to\ntrue. Defaults to 'dir'.
\nDefaults to: "dir"
Extra parameters that will be included on every request. Individual requests with params of the same name\nwill override these params when they are in conflict.
\nThe name of the 'filter' parameter to send in a request. Defaults to 'filter'. Set this to undefined if you don't\nwant to send a filter parameter.
\nDefaults to: "filter"
The name of the 'group' parameter to send in a request. Defaults to 'group'. Set this to undefined if you don't\nwant to send a group parameter.
\nDefaults to: "group"
The name of the 'limit' parameter to send in a request. Defaults to 'limit'. Set this to undefined if you don't\nwant to send a limit parameter.
\nDefaults to: "limit"
A config object containing one or more event handlers to be added to this object during initialization. This\nshould be a valid listeners config object as specified in the addListener example for attaching multiple\nhandlers at once.
\n\nDOM events from Ext JS Components
\n\nWhile some Ext JS Component classes export selected DOM events (e.g. \"click\", \"mouseover\" etc), this is usually\nonly done when extra value can be added. For example the DataView's itemclick event passing the node clicked on. To access DOM events directly from a\nchild element of a Component, we need to specify the element option to identify the Component property to add a\nDOM 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});\nThe name of the Model to tie to this Proxy. Can be either the string name of the Model, or a reference to the\nModel constructor. Required.
\nDisable caching by adding a unique parameter name to the request. Set to false to allow caching. Defaults to true.
\nDefaults to: true
The name of the 'page' parameter to send in a request. Defaults to 'page'. Set this to undefined if you don't\nwant to send a page parameter.
\nDefaults to: "page"
The Ext.data.reader.Reader to use to decode the server's response or data read from client. This can either be a\nReader instance, a config object or just a valid Reader type name (e.g. 'json', 'xml').
\nThe param name to use when passing records to the server (e.g. 'records=someEncodedRecordString'). Defaults to\n'records'
\nDefaults to: "records"
Enabling simpleSortMode in conjunction with remoteSort will only send one sort property and a direction when a\nremote sort is requested. The directionParam and sortParam will be sent with the property name and either 'ASC'\nor 'DESC'.
\nDefaults to: false
The name of the 'sort' parameter to send in a request. Defaults to 'sort'. Set this to undefined if you don't\nwant to send a sort parameter.
\nDefaults to: "sort"
The name of the 'start' parameter to send in a request. Defaults to 'start'. Set this to undefined if you don't\nwant to send a start parameter.
\nDefaults to: "start"
The number of milliseconds to wait for a response. Defaults to 30000 milliseconds (30 seconds).
\nDefaults to: 30000
The Ext.data.writer.Writer to use to encode any request sent to the server or saved to client. This can either be\na Writer instance, a config object or just a valid Writer type name (e.g. 'json', 'xml').
\nGet the reference to the current class from which this object was instantiated. Unlike statics,\nthis.self is scope-dependent and it's meant to be used for dynamic inheritance. See statics\nfor a detailed comparison
Ext.define('My.Cat', {\n statics: {\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n alert(this.self.speciesName); / dependent on 'this'\n\n return this;\n },\n\n clone: function() {\n return new this.self();\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat'\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\nAborts the current server request if one is currently running
\nAdds the specified events to the list of events which this Observable may fire.
\nEither an object with event names as properties with a value of true or the first\nevent name string if multiple event names are being passed as separate parameters. Usage:
this.addEvents({\n storeloaded: true,\n storecleared: true\n});\nAdditional event names if multiple event names are being passed as separate\nparameters. Usage:
\n\nthis.addEvents('storeloaded', 'storecleared');\nAppends an event handler to this object.
\nThe name of the event to listen for. May also be an object who's property names are\nevent names.
\n\nThe method the event invokes. Will be called with arguments given to\nfireEvent plus the options parameter described below.
The scope (this reference) in which the handler function is executed. If\nomitted, defaults to the object which fired the event.
An object containing handler configuration.
\n\n\n\n\nNote: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.
\n\n\n\n\nThis object may contain any of the following properties:
\n\n\n\n\nscope : Object
\n\nThe scope (this reference) in which the handler function is executed. If omitted, defaults to the object\nwhich fired the event.
delay : Number
\n\nThe number of milliseconds to delay the invocation of the handler after the event fires.

\n\nTrue to add a handler to handle just the next firing of the event, and then remove itself.
buffer : Number
\n\nCauses the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of\nmilliseconds. If the event fires again within that time, the original handler is not invoked, but the new\nhandler is scheduled in its place.
target : Observable
\n\nOnly call the handler if the event was fired on the target Observable, not if the event was bubbled up from a\nchild Observable.
element : String
\n\nThis option is only valid for listeners bound to Components. The name of a Component\nproperty which references an element to add a listener to.
\n\nThis option is useful during Component construction to add DOM event listeners to elements of\nComponents which will exist only after the Component is rendered.\nFor example, to add a click listener to a Panel's body:
\n\nnew Ext.panel.Panel({\n title: 'The title',\n listeners: {\n click: this.handlePanelClick,\n element: 'body'\n }\n});\nCombining Options
\n\n\n\n\nUsing the options argument, it is possible to combine different types of listeners:
\n\n\n\n\nA delayed, one-time listener.
\n\n\n\n\nmyPanel.on('hide', this.handleClick, this, {\n single: true,\n delay: 100\n});\nAttaching multiple handlers in 1 call
\n\n\n\n\nThe method also allows for a single argument to be passed which is a config object containing properties which\nspecify multiple events. For example:
\n\n\n\n\nmyGridPanel.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});\nOne can also specify options for each event handler separately:
\n\n\n\n\nmyGridPanel.on({\n cellClick: {fn: this.onCellClick, scope: this, single: true},\n mouseover: {fn: panel.onMouseOver, scope: panel}\n});\nAdds listeners to any Observable object (or Ext.Element) which are automatically removed when this Component is\ndestroyed.
\nThe item to which to add a listener/listeners.
\n\nThe event name, or an object containing event name properties.
\n\nIf the ename parameter was an event name, this is the handler function.

If the ename parameter was an event name, this is the\naddListener options.
Optional callback function which can be used to clean up after a request has been completed.
\nThe Request object
\nTrue if the request was successful
\nPerforms a batch of Operations, in the order specified by batchOrder. Used\ninternally by Ext.data.Store's sync method. Example usage:
\n\nmyProxy.batch({\n create : [myModel1, myModel2],\n update : [myModel3],\n destroy: [myModel4, myModel5]\n});\nWhere the myModel* above are Model instances - in this case 1 and 2 are new instances and\nhave not been saved before, 3 has been saved previously but needs to be updated, and 4 and 5 have already been\nsaved but should now be destroyed.
\nObject containing the Model instances to act upon, keyed by action name
\nlisteners object passed straight through to the Batch -\nsee Ext.data.Batch
\nThe newly created Ext.data.Batch object
\nCreates and returns an Ext.data.Request object based on the options passed by the Store\nthat this Proxy is attached to.
\nThe Operation object to execute
\nThe request object
\nGenerates a url based on a given Ext.data.Request object. Adds the params and callback function name to the url
\nThe request object
\nThe url
\nCall the original method that was previously overridden with override
\n\nExt.define('My.Cat', {\n constructor: function() {\n alert(\"I'm a cat!\");\n\n return this;\n }\n});\n\nMy.Cat.override({\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n var instance = this.callOverridden();\n\n alert(\"Meeeeoooowwww\");\n\n return instance;\n }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n // alerts \"I'm a cat!\"\n // alerts \"Meeeeoooowwww\"\nThe arguments, either an array or the arguments object
Returns the result after calling the overridden method
\nCall the parent's overridden method. For example:
\n\nExt.define('My.own.A', {\n constructor: function(test) {\n alert(test);\n }\n});\n\nExt.define('My.own.B', {\n extend: 'My.own.A',\n\n constructor: function(test) {\n alert(test);\n\n this.callParent([test + 1]);\n }\n});\n\nExt.define('My.own.C', {\n extend: 'My.own.B',\n\n constructor: function() {\n alert(\"Going to call parent's overriden constructor...\");\n\n this.callParent(arguments);\n }\n});\n\nvar a = new My.own.A(1); // alerts '1'\nvar b = new My.own.B(1); // alerts '1', then alerts '2'\nvar c = new My.own.C(2); // alerts \"Going to call parent's overriden constructor...\"\n // alerts '2', then alerts '3'\nThe arguments, either an array or the arguments object\nfrom the current method, for example: this.callParent(arguments)
Returns the result from the superclass' method
\nRemoves all listeners for this object including the managed listeners
\nPerforms the given create operation.

\nScope to execute the callback function in
\nIn ServerProxy subclasses, the create, read, update and destroy methods all\npass 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\neach of the methods that delegate to it.
\nThe Ext.data.Operation object
\nThe callback function to call when the Operation has completed
\nThe scope in which to execute the callback
\nEnables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if\npresent. There is no implementation in the Observable base class.
This is commonly used by Ext.Components to bubble events to owner Containers.\nSee Ext.Component.getBubbleTarget. The default implementation in Ext.Component returns the\nComponent's immediate owner. But if a known target is required, this can be overridden to access the\nrequired target more quickly.
\n\nExample:
\n\nExt.override(Ext.form.field.Base, {\n // Add functionality to Field's initComponent to enable the change event to bubble\n initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {\n this.enableBubble('change');\n }),\n\n // We know that we want Field's events to bubble directly to the FormPanel.\n getBubbleTarget : function() {\n if (!this.formPanel) {\n this.formPanel = this.findParentByType('form');\n }\n return this.formPanel;\n }\n});\n\nvar myForm = new Ext.formPanel({\n title: 'User Details',\n items: [{\n ...\n }],\n listeners: {\n change: function() {\n // Title goes red if form has been modified.\n myForm.header.setStyle('color', 'red');\n }\n }\n});\nEncodes the array of Ext.util.Filter objects into a string to be sent in the request url. By default,\nthis simply JSON-encodes the filter data
\nThe array of Filter objects
\nThe encoded filters
\nEncodes an array of records into a string suitable to be appended to the script src url. This is broken out into\nits own function so that it can be easily overridden.
\nThe records array
\nThe encoded records string
\nEncodes the array of Ext.util.Sorter objects into a string to be sent in the request url. By default,\nthis simply JSON-encodes the sorter data
\nThe array of Sorter objects
\nThe encoded sorters
\nFires the specified event with the passed parameters (minus the event name, plus the options object passed\nto addListener).
An event may be set to bubble up an Observable parent hierarchy (See Ext.Component.getBubbleTarget) by\ncalling enableBubble.
\nThe name of the event to fire.
\nVariable number of parameters are passed to handlers.
\nreturns false if any of the handlers return false otherwise it returns true.
\nReturns the reader currently attached to this proxy instance
\nThe Reader instance
\nReturns the writer currently attached to this proxy instance
\nThe Writer instance
\nInitialize configuration for this class. a typical example:
\n\nExt.define('My.awesome.Class', {\n // The default config\n config: {\n name: 'Awesome',\n isAwesome: true\n },\n\n constructor: function(config) {\n this.initConfig(config);\n\n return this;\n }\n});\n\nvar awesome = new My.awesome.Class({\n name: 'Super Awesome'\n});\n\nalert(awesome.getName()); // 'Super Awesome'\nmixins The mixin prototypes as key - value pairs

(see resumeEvents)
\nPass as true to queue up suspended events to be fired\nafter the resumeEvents call instead of discarding all suspended events.
\nShorthand for removeListener.
\n\nRemoves an event handler.
\nThe type of event the handler was associated with.
\n\nThe handler to remove. This must be a reference to the function passed into the\naddListener call.
\n\nThe scope originally specified for the handler. It must be the same as the\nscope argument specified in the original call to addListener or the listener will not be removed.
\n\nPerforms the given update operation.
\nThe Operation to perform
\nCallback function to be called when the Operation has completed (whether successful or not)
\nScope to execute the callback function in
\nAdd / override static properties of this class.

\nCreate a new instance of this Class.
\n\nExt.define('My.cool.Class', {\n ...\n});\n\nMy.cool.Class.create({\n someConfig: true\n});\nAll parameters are passed to the constructor of the class.
\nthe created instance.
\nCreate aliases for existing prototype methods. Example:
\n\nExt.define('My.cool.Class', {\n method1: function() { ... },\n method2: function() { ... }\n});\n\nvar test = new My.cool.Class();\n\nMy.cool.Class.createAlias({\n method3: 'method1',\n method4: 'method2'\n});\n\ntest.method3(); // test.method1()\n\nMy.cool.Class.createAlias('method5', 'method3');\n\ntest.method5(); // test.method3() -> test.method1()\nThe new method name, or an object to set multiple aliases. See\nflexSetter
\nThe original method name
\nGet the current class' name in string format.
\n\nExt.define('My.cool.Class', {\n constructor: function() {\n alert(this.self.getName()); // alerts 'My.cool.Class'\n }\n});\n\nMy.cool.Class.getName(); // 'My.cool.Class'\nclassName
