Proxies are used by Stores to handle the loading and saving of Model data. Usually developers will not need to create or interact with proxies directly.

Types of Proxy

There are two main types of Proxy - Client and Server. The Client proxies save their data locally and include the following subclasses:

  • LocalStorageProxy - saves its data to localStorage if the browser supports it
  • MemoryProxy - holds data in memory only, any data is lost when the page is refreshed

The Server proxies save their data by sending requests to some remote server. These proxies include:

  • Ajax - sends requests to a server on the same domain
  • JsonP - uses JSON-P to send requests to a server on a different domain

Proxies operate on the principle that all operations performed are either Create, Read, Update or Delete. These four operations are mapped to the methods create, read, update and destroy respectively. Each Proxy subclass implements these functions.

The CRUD methods each expect an Operation object as the sole argument. The Operation encapsulates information about the action the Store wishes to perform, the model instances that are to be modified, etc. See the Operation documentation for more details. Each CRUD method also accepts a callback function to be called asynchronously on completion.

Proxies also support batching of Operations via a batch object, invoked by the batch method.

          Available since: 1.1.0

          This method has been deprecated since 2.0

          It's no longer needed to add events before firing.

          Parameters

          • eventNames : Object/String...

            Either an object with event names as properties with a value of true or the first event name string if multiple event names are being passed as separate parameters.

          Appends an event handler to this object. You can review the available handlers by looking at the 'events' section of the documentation for the component you are working with.

          Combining Options

          Using the options argument, it is possible to combine different types of listeners:

          A delayed, one-time listener:

          container.on('tap', this.handleTap, 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:

          container.on({
              tap  : this.onTap,
              swipe: this.onSwipe,
          
              scope: this // Important. Ensure "this" is correct during handler execution
          });
          

          One can also specify options for each event handler separately:

          container.on({
              tap  : { fn: this.onTap, scope: this, single: true },
              swipe: { fn: button.onSwipe, scope: button }
          });
          

          See the Events Guide for more.

          Available since: 1.1.0

          Parameters

          • eventName : String/String[]/Object

            The name of the event to listen for. May also be an object who's property names are event names.

          • fn : Function/String

            The method the event invokes. Will be called with arguments given to fireEvent plus the options parameter described below.

          • scope : Object (optional)

            The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

          • options : Object (optional)

            An object containing handler configuration.

            This object may contain any of the following properties:

            • scope : Object (optional)

              The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

            • delay : Number (optional)

              The number of milliseconds to delay the invocation of the handler after the event fires.

            • single : Boolean (optional)

              true to add a handler to handle just the next firing of the event, and then remove itself.

            • order : String (optional)

              The order of when the listener should be added into the listener queue.

              If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.

              Available options are before, current and after.

              Defaults to: current

            • buffer : Number (optional)

              Causes the handler to be delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

            • element : String (optional)

              Allows you to add a listener onto a element of this component using the elements reference.

              Ext.create('Ext.Component', {
                  listeners: {
                      element: 'element',
                      tap: function() {
                          alert('element tap!');
                      }
                  }
              });
              

              All components have the element reference, which is the outer most element of the component. Ext.Container also has the innerElement element which contains all children. In most cases element is adequate.

            • delegate : String (optional)

              Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.

              // Create a container with a two children; a button and a toolbar
              var container = Ext.create('Ext.Container', {
                  items: [
                      {
                          xtype: 'toolbar',
                          docked: 'top',
                          title: 'My Toolbar'
                      },
                      {
                         xtype: 'button',
                         text: 'My Button'
                      }
                  ]
              });
              
              container.on({
                  // Ext.Buttons have an xtype of 'button', so we use that are a selector for our delegate
                  delegate: 'button',
              
                  tap: function() {
                      alert('Button tapped!');
                  }
              });
              
          • order : String (optional)

            The order of when the listener should be added into the listener queue. Possible values are before, current and after.

            Defaults to: 'current'

                  Call the "parent" method of the current method. ...

                  Call the "parent" method of the current method. That is the method previously overridden by derivation or by an override (see Ext.define).

                   Ext.define('My.Base', {
                       constructor: function (x) {
                           this.x = x;
                       },
                  
                       statics: {
                           method: function (x) {
                               return x;
                           }
                       }
                   });
                  
                   Ext.define('My.Derived', {
                       extend: 'My.Base',
                  
                       constructor: function () {
                           this.callParent([21]);
                       }
                   });
                  
                   var obj = new My.Derived();
                  
                   alert(obj.x);  // alerts 21
                  

                  This can be used with an override as follows:

                   Ext.define('My.DerivedOverride', {
                       override: 'My.Derived',
                  
                       constructor: function (x) {
                           this.callParent([x*2]); // calls original My.Derived constructor
                       }
                   });
                  
                   var obj = new My.Derived();
                  
                   alert(obj.x);  // now alerts 42
                  

                  This also works with static methods.

                   Ext.define('My.Derived2', {
                       extend: 'My.Base',
                  
                       statics: {
                           method: function (x) {
                               return this.callParent([x*2]); // calls My.Base.method
                           }
                       }
                   });
                  
                   alert(My.Base.method(10));     // alerts 10
                   alert(My.Derived2.method(10)); // alerts 20
                  

                  Lastly, it also works with overridden static methods.

                   Ext.define('My.Derived2Override', {
                       override: 'My.Derived2',
                  
                       statics: {
                           method: function (x) {
                               return this.callParent([x*2]); // calls My.Derived2.method
                           }
                       }
                   });
                  
                   alert(My.Derived2.method(10)); // now alerts 40
                  

                  To override a method and replace it and also call the superclass method, use callSuper. This is often done to patch a method to fix a bug.

                  Available since: 2.0.0

                  Parameters

                  • args : Array/Arguments

                    The arguments, either an array or the arguments object from the current method, for example: this.callParent(arguments)

                  Returns

                  • Object

                    Returns the result of calling the parent method

                  This method is used by an override to call the superclass method but bypass any overridden method. ...

                  This method is used by an override to call the superclass method but bypass any overridden method. This is often done to "patch" a method that contains a bug but for whatever reason cannot be fixed directly.

                  Consider:

                   Ext.define('Ext.some.Class', {
                       method: function () {
                           console.log('Good');
                       }
                   });
                  
                   Ext.define('Ext.some.DerivedClass', {
                       method: function () {
                           console.log('Bad');
                  
                           // ... logic but with a bug ...
                  
                           this.callParent();
                       }
                   });
                  

                  To patch the bug in DerivedClass.method, the typical solution is to create an override:

                   Ext.define('App.paches.DerivedClass', {
                       override: 'Ext.some.DerivedClass',
                  
                       method: function () {
                           console.log('Fixed');
                  
                           // ... logic but with bug fixed ...
                  
                           this.callSuper();
                       }
                   });
                  

                  The patch method cannot use callParent to call the superclass method since that would call the overridden method containing the bug. In other words, the above patch would only produce "Fixed" then "Good" in the console log, whereas, using callParent would produce "Fixed" then "Bad" then "Good".

                                    Fires the specified event with the passed parameters (minus the event name, plus the options object passed to addListener).

                                    The first argument is the name of the event. Every other argument passed will be available when you listen for the event.

                                    Example

                                    Firstly, we set up a listener for our new event.

                                    this.on('myevent', function(arg1, arg2, arg3, arg4, options, e) {
                                        console.log(arg1); // true
                                        console.log(arg2); // 2
                                        console.log(arg3); // { test: 'foo' }
                                        console.log(arg4); // 14
                                        console.log(options); // the options added when adding the listener
                                        console.log(e); // the event object with information about the event
                                    });
                                    

                                    And then we can fire off the event.

                                    this.fireEvent('myevent', true, 2, { test: 'foo' }, 14);
                                    

                                    An event may be set to bubble up an Observable parent hierarchy by calling enableBubble.

                                                  • options : Object (optional)

                                                    An object containing handler configuration.

                                                    This object may contain any of the following properties:

                                                    • scope : Object (optional)

                                                      The scope (this reference) in which the handler function is executed. If omitted, defaults to the object which fired the event.

                                                    • delay : Number (optional)

                                                      The number of milliseconds to delay the invocation of the handler after the event fires.

                                                    • single : Boolean (optional)

                                                      true to add a handler to handle just the next firing of the event, and then remove itself.

                                                    • order : String (optional)

                                                      The order of when the listener should be added into the listener queue.

                                                      If you set an order of before and the event you are listening to is preventable, you can return false and it will stop the event.

                                                      Available options are before, current and after.

                                                      Defaults to: current

                                                    • buffer : Number (optional)

                                                      Causes the handler to be delayed by the specified number of milliseconds. If the event fires again within that time, the original handler is not invoked, but the new handler is scheduled in its place.

                                                    • element : String (optional)

                                                      Allows you to add a listener onto a element of this component using the elements reference.

                                                      Ext.create('Ext.Component', {
                                                          listeners: {
                                                              element: 'element',
                                                              tap: function() {
                                                                  alert('element tap!');
                                                              }
                                                          }
                                                      });
                                                      

                                                      All components have the element reference, which is the outer most element of the component. Ext.Container also has the innerElement element which contains all children. In most cases element is adequate.

                                                    • delegate : String (optional)

                                                      Uses Ext.ComponentQuery to delegate events to a specified query selector within this item.

                                                      // Create a container with a two children; a button and a toolbar
                                                      var container = Ext.create('Ext.Container', {

                                                                  xtype: 'toolbar',
