Controllers are the glue that binds an application together. All they really do is listen for events (usually from views) and take some action. Here's how we might create a Controller to manage Users:

 Ext.define('MyApp.controller.Users', {
     extend: 'Ext.app.Controller',

     init: function() {
         console.log('Initialized Users! This happens before ' +
                     'the Application launch() function is called');
     }
 });

The init function is a special method that is called when your application boots. It is called before the Application's launch function is executed so gives a hook point to run any code before your Viewport is created.

The init function is a great place to set up how your controller interacts with the view, and is usually used in conjunction with another Controller function - control. The control function makes it easy to listen to events on your view classes and take some action with a handler function. Let's update our Users controller to tell us when the panel is rendered:

 Ext.define('MyApp.controller.Users', {
     extend: 'Ext.app.Controller',

     init: function() {
         this.control({
             'viewport > panel': {
                 render: this.onPanelRendered
             }
         });
     },

     onPanelRendered: function() {
         console.log('The panel was rendered');
     }
 });

We've updated the init function to use control method to set up listeners on views in our application. The control method uses the ComponentQuery engine to quickly and easily get references to components on the page. If you are not familiar with ComponentQuery yet, be sure to check out the documentation. In brief though, it allows us to pass a CSS-like selector that will find every matching component on the page.

In our init function above we supplied 'viewport > panel', which translates to "find me every Panel that is a direct child of a Viewport". We then supplied an object that maps event names (just 'render' in this case) to handler functions. The overall effect is that whenever any component that matches our selector fires a 'render' event, our onPanelRendered function is called.

Event domains

In Ext JS 4.2, we introduced the concept of event domains. In terms of MVC, an event domain is one or more base classes that fire events to which a Controller wants to listen. Besides Component event domain that encompass Ext.Component-descended Views, Controllers now can listen to events from data Stores, Ext.Direct Providers, other Controllers, and Ext.globalEvents. This feature provides a way to communicate between parts of the whole application without the need to bind controllers together tightly, and allows to develop and test application parts in isolation.

See usage examples in listen method documentation.

Using refs

One of the most useful parts of Controllers is the ref system. These use the Ext.ComponentQuery to make it really easy to get references to Views on your page. Let's look at an example of this now:

 Ext.define('MyApp.controller.Users', {
     extend: 'Ext.app.Controller',

     refs: [{
         ref: 'list',
         selector: 'grid'
     }],

     init: function() {
         this.control({
             'button': {
                 click: this.refreshGrid
             }
         });
     },

     refreshGrid: function() {
         this.getList().store.load();
     }
 });

This example assumes the existence of a Grid on the page, which contains a single button to refresh the Grid when clicked. In our refs array, we set up a reference to the grid. There are two parts to this - the 'selector', which is a ComponentQuery selector which finds any grid on the page and assigns it to the reference 'list'.

By giving the reference a name, we get a number of things for free. The first is the getList function that we use in the refreshGrid method above. This is generated automatically by the Controller based on the name of our ref, which was capitalized and prepended with get to go from 'list' to 'getList'.

The way this works is that the first time getList is called by your code, the ComponentQuery selector is run and the first component that matches the selector ('grid' in this case) will be returned. All future calls to getList will use a cached reference to that grid. Usually it is advised to use a specific ComponentQuery selector that will only match a single View in your application (in the case above our selector will match any grid on the page).

Bringing it all together, our init function is called when the application boots, at which time we call this.control to listen to any click on a button and call our refreshGrid function (again, this will match any button on the page so we advise a more specific selector than just 'button', but have left it this way for simplicity). When the button is clicked we use out getList function to refresh the grid.

You can create any number of refs and control any number of components this way, simply adding more functions to your Controller as you go. For an example of real-world usage of Controllers see the Feed Viewer example in the examples/app/feed-viewer folder in the SDK download.

Generated getter methods

Refs aren't the only thing that generate convenient getter methods. Controllers often have to deal with Models and Stores so the framework offers a couple of easy ways to get access to those too. Let's look at another example:

 Ext.define('MyApp.controller.Users', {
     extend: 'Ext.app.Controller',

     models: ['User'],
     stores: ['AllUsers', 'AdminUsers'],

     init: function() {
         var User, allUsers, ed;

         User = this.getUserModel();
         allUsers = this.getAllUsersStore();

         ed = new User({ name: 'Ed' });
         allUsers.add(ed);
     }
 });

By specifying Models and Stores that the Controller cares about, it again dynamically loads them from the appropriate locations (app/model/User.js, app/store/AllUsers.js and app/store/AdminUsers.js in this case) and creates getter functions for them all. The example above will create a new User model instance and add it to the AllUsers Store. Of course, you could do anything in this function but in this case we just did something simple to demonstrate the functionality.

DOM events from Ext JS Components

While some Ext JS 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 itemclick 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

         selector: 'grid'
     }],
 });

This will add method getList to the controller which will internally use Ext.ComponentQuery to reference the grid component on page.

The following fields can be used in ref definition:

  • ref - name of the reference.
  • selector - Ext.ComponentQuery selector to access the component.
  • autoCreate - True to create the component automatically if not found on page.
  • forceCreate - Forces the creation of the component every time reference is accessed (when get<REFNAME> is called).
  • xtype - Used to create component by its xtype with autoCreate or forceCreate. If you don't provide xtype, an Ext.Component instance will be created.

This object holds a key for any event that has a listener. ...

This object holds a key for any event that has a listener. The listener may be set directly on the instance, or on its class or a super class (via observe) or on the MVC EventBus. The values of this object are truthy (a non-zero number) and falsy (0 or undefined). They do not represent an exact count of listeners. The value for an event is truthy if the event must be fired and is falsy if there is no need to fire the event.

The intended use of this property is to avoid the expense of fireEvent calls when there are no listeners. This can be particularly helpful when one would otherwise have to call fireEvent hundreds or thousands of times. It is used like this:

 if (this.hasListeners.foo) {
     this.fireEvent('foo', this, arg1);

    Adds the specified events to the list of events which this Observable may fire.

    Available since: 1.1.0

    Parameters

    • eventNames : Object/String...

      Either an object with event names as properties with a value of true. For example:

      this.addEvents({
          storeloaded: true,
          storecleared: true
      });
      

      Or any number of event names as separate parameters. For example:

      this.addEvents('storeloaded', 'storecleared');
      
    ( eventName, [fn], [scope], [options] ) : Object
    Appends an event handler to this object. ...

    Appends an event handler to this object. For example:

    myGridPanel.on("mouseover", this.onMouseOver, this);
    

    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
    });
    

    One can also specify options for each event handler separately:

    myGridPanel.on({
        cellClick: {fn: this.onCellClick, scope: this, single: true},
        mouseover: {fn: panel.onMouseOver, scope: panel}
    });
    

    Names of methods in a specified scope may also be used. Note that scope MUST be specified to use this option:

    myGridPanel.on({
        cellClick: {fn: 'onCellClick', scope: this, single: true},
        mouseover: {fn: 'onMouseOver', scope: panel}
    });
    

    Available since: 1.1.0

    Parameters

    • eventName : String/Object

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

    • fn : Function (optional)

      The method the event invokes, or if scope is specified, the name* of the method within the specified scope. 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.

      Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

      This object may contain any of the following properties:

      • scope : Object

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

      • delay : Number

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

      • single : Boolean

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

      • buffer : Number

        Causes the handler to be scheduled to run in an Ext.util.DelayedTask 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.

      • target : Ext.util.Observable

        Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

      • element : String

        This option is only valid for listeners bound to Components. The name of a Component property which references an element to add a listener to.

        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'
              }
          });
        
      • destroyable : Boolean (optional)

        When specified as true, the function returns A Destroyable object. An object which implements the destroy method which removes all listeners added in this call.

        Defaults to: false

      • priority : Number (optional)

        An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code.

        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
        });
        

    Returns

    • Object

      Only when the destroyable option is specified.

      A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

      this.btnListeners =  = myButton.on({
          destroyable: true
          mouseover:   function() { console.log('mouseover'); },
          mouseout:    function() { console.log('mouseout'); },
          click:       function() { console.log('click'); }
      });
      

      And when those listeners need to be removed:

      Ext.destroy(this.btnListeners);
      

      or

      this.btnListeners.destroy();

                   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: 4.0.0

          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".

                Adds listeners to components selected via Ext.ComponentQuery. Accepts an object containing component paths mapped to a hash of listener functions.

                In the following example the updateUser function is mapped to to the click event on a button component, which is a child of the useredit component.

                 Ext.define('AM.controller.Users', {
                     init: function() {
                         this.control({
                             'useredit button[action=save]': {
                                 click: this.updateUser
                             }
                         });
                     },
                
                     updateUser: function(button) {
                         console.log('clicked the Save button');
                     }
                 });
                

                Or alternatively one call control with two arguments:

                 this.control('useredit button[action=save]', {
                     click: this.updateUser
                 });

                  Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if present. ...

                  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.define('Ext.overrides.form.field.Base', {
                      override: 'Ext.form.field.Base',
                  
                      //  Add functionality to Field's initComponent to enable the change event to bubble
                      initComponent: function () {
                          this.callParent();
                          this.enableBubble('change');
                      }
                  });
                  
                  var myForm = Ext.create('Ext.form.Panel', {
                      title: 'User Details',
                      items: [{
                          ...
                      }],
                      listeners: {
                          change: function() {
                              // Title goes red if form has been modified.
                              myForm.header.setStyle('color', 'red');
                          }

                        Initialize configuration for this class. ...

                        Initialize configuration for this class. a typical example:

                        Ext.define('My.awesome.Class', {
                            // The default config

                        Parameters

                        Returns

                        Ext.app.Controller
                        view source
                        ( to )
                        Adds listeners to different event sources (also called "event domains"). ...

                        Adds listeners to different event sources (also called "event domains"). The primary event domain is that of components, but there are also other event domains: Global domain that intercepts events fired from Ext.globalEvents Observable instance, Controller domain can be used to listen to events fired by other Controllers, Store domain gives access to Store events, and Direct domain can be used with Ext.Direct Providers to listen to their events.

                        To listen to "bar" events fired by a controller with id="foo":

                         Ext.define('AM.controller.Users', {
                             init: function() {
                                 this.listen({
                                     controller: {
                                         '#foo': {
                                            bar: this.onFooBar
                                         }
                                     }
                                 });
                             },
                             ...
                         });
                        

                        To listen to "bar" events fired by any controller, and "baz" events fired by Store with storeId="baz":

                         Ext.define('AM.controller.Users', {
                             init: function() {
                                 this.listen({
                                     controller: {
                                         '*': {
                                            bar: this.onAnyControllerBar
                                         }
                                     },
                                     store: {
                                         '#baz': {
                                             baz: this.onStoreBaz
                                         }
                                     }
                                 });
                             },
                             ...
                         });
                        

                        To listen to "idle" events fired by Ext.globalEvents when other event processing is complete and Ext JS is about to return control to the browser:

                         Ext.define('AM.controller.Users', {
                             init: function() {
                                 this.listen({
                                     global: {               // Global events are always fired
                                         idle: this.onIdle   // from the same object, so there
                                     }                       // are no selectors
                                 });
                             }
                         });
                        

                        As this relates to components, the following example:

                         Ext.define('AM.controller.Users', {
                             init: function() {
                                 this.listen({
                                     component: {
                                         'useredit button[action=save]': {
                                            click: this.updateUser
                                         }
                                     }
                                 });
                             },
                             ...
                         });
                        

                        Is equivalent to:

                         Ext.define('AM.controller.Users', {
                             init: function() {
                                 this.control({
                                     'useredit button[action=save]': {
                                        click: this.updateUser
                                     }
                                 });
                             },
                             ...
                         });
                        

                        Of course, these can all be combined in a single call and used instead of control, like so:

                         Ext.define('AM.controller.Users', {
                             init: function() {
                                 this.listen({
                                     global: {
                                         idle: this.onIdle
                                     },
                                     controller: {
                                         '*': {
                                            foobar: this.onAnyFooBar
                                         },
                                         '#foo': {
                                            bar: this.onFooBar
                                         }
                                     },
                                     component: {
                                         'useredit button[action=save]': {
                                            click: this.updateUser
                                         }
                                     },
                                     store: {
                                         '#qux': {
                                             load: this.onQuxLoad
                                         }
                                     }
                                 });
                             },
                             ...
                         });

                        Parameters

                        • item : Ext.util.Observable/Ext.Element

                          The item to which to add a listener/listeners.

                        • ename : Object/String

                          The event name, or an object containing event name properties.

                        • fn : Function (optional)

                          If the ename parameter was an event name, this is the handler function.

                        • scope : Object (optional)

                          If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

                        • options : Object (optional)

                          If the ename parameter was an event name, this is the addListener options.

                        Returns

                        • Object

                          Only when the destroyable option is specified.

                          A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

                          this.btnListeners =  = myButton.mon({
                              destroyable: true
                              mouseover:   function() { console.log('mouseover'); },
                              mouseout:    function() { console.log('mouseout'); },
                              click:       function() { console.log('click'); }
                          });
                          

                          And when those listeners need to be removed:

                          Ext.destroy(this.btnListeners);
                          

                          or

                          this.btnListeners.destroy();
                          
                        ( item, ename, [fn], [scope] )
                        Shorthand for removeManagedListener. ...

                        • item : Ext.util.Observable/Ext.Element

                          The item from which to remove a listener/listeners.

                        • ename : Object/String

                          The event name, or an object containing event name properties.

                        • fn : Function (optional)

                          If the ename parameter was an event name, this is the handler function.

                        • scope : Object (optional)

                          If the ename parameter was an event name, this is the scope (this reference) in which the handler function is executed.

                        ( eventName, [fn], [scope], [options] ) : Object
                        Shorthand for addListener. ...

                        Shorthand for addListener.

                        Available since: 1.1.0

                        Parameters

                        • eventName : String/Object

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

                        • fn : Function (optional)

                          The method the event invokes, or if scope is specified, the name* of the method within the specified scope. 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.

                          Note: Unlike in ExtJS 3.x, the options object will also be passed as the last argument to every event handler.

                          This object may contain any of the following properties:

                          • scope : Object

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

                          • delay : Number

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

                          • single : Boolean

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

                          • buffer : Number

                            Causes the handler to be scheduled to run in an Ext.util.DelayedTask 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.

                          • target : Ext.util.Observable

                            Only call the handler if the event was fired on the target Observable, not if the event was bubbled up from a child Observable.

                          • element : String

                            This option is only valid for listeners bound to Components. The name of a Component property which references an element to add a listener to.

                            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({

                                      click: this.handlePanelClick,
                                      element: 'body'
                                  }

                          • destroyable : Boolean (optional)

                            When specified as true, the function returns A Destroyable object. An object which implements the destroy method which removes all listeners added in this call.

                            Defaults to: false

                          • priority : Number (optional)

                            An optional numeric priority that determines the order in which event handlers are run. Event handlers with no priority will be run as if they had a priority of 0. Handlers with a higher priority will be prioritized to run sooner than those with a lower priority. Negative numbers can be used to set a priority lower than the default. Internally, the framework uses a range of 1000 or greater, and -1000 or lesser for handers that are intended to run before or after all others, so it is recommended to stay within the range of -999 to 999 when setting the priority of event handlers in application-level code.

                            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
                            });
                            

                        Returns

                        • Object

                          Only when the destroyable option is specified.

                          A Destroyable object. An object which implements the destroy method which removes all listeners added in this call. For example:

                          this.btnListeners =  = myButton.on({
                              destroyable: true
                              mouseover:   function() { console.log('mouseover'); },
                              mouseout:    function() { console.log('mouseout'); },
                              click:       function() { console.log('click'); }
                          });
                          

                          And when those listeners need to be removed:

                          Ext.destroy(this.btnListeners);
                          

                          or

                        Parameters

                        • T : Function

                          The class constructor to prepare.

                        Ext.app.Controller

                        Relays selected events from the specified Observable as if the events were fired by this.

                        For example if you are extending Grid, you might decide to forward some events from store. So you can do this inside your initComponent:

                        this.relayEvents(this.getStore(), ['load']);
                        

                        The grid instance will then have an observable 'load' event which will be passed the parameters of the store's load event and any function fired with the grid's load event would have access to the grid using the this keyword.

                        Available since: 2.3.0

                        Parameters

                        • origin : Object

                          The Observable whose events this object is to relay.

                        • events : String[]

                          Array of event names to relay.

                        • prefix : String (optional)

                          A common prefix to prepend to the event names. For example:

                          this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
                          

                          Now the grid will forward 'load' and 'clear' events of store as 'storeload' and 'storeclear'.

                        Returns

                        • Object

                          A Destroyable object. An object which implements the destroy method which, when destroyed, removes all relayers. For example:

                          this.storeRelayers = this.relayEvents(this.getStore(), ['load', 'clear'], 'store');
                          

                          Can be undone by calling

                                The type of event the handler was associated with.

                              • fn : Function

                                The handler to remove. This must be a reference to the function passed into the addListener call.

                                  }
                              });
                              

                              The above accomplishes the same result but can be managed by the Ext.Loader which can properly order the override and its target class and the build process can determine whether the override is needed based on the required state of the target class (My.Cat).
