The Store class encapsulates a client side cache of Model objects. Stores load data via a Proxy, and also provide functions for sorting, filtering and querying the model instances contained within it.

Creating a Store is easy - we just tell it the Model and the Proxy to use to load and save its data:

 // Set up a model to use in our Store
 Ext.define('User', {
     extend: 'Ext.data.Model',
     fields: [
         {name: 'firstName', type: 'string'},
         {name: 'lastName',  type: 'string'},
         {name: 'age',       type: 'int'},
         {name: 'eyeColor',  type: 'string'}
     ]
 });

 var myStore = Ext.create('Ext.data.Store', {
     model: 'User',
     proxy: {
         type: 'ajax',
         url: '/users.json',
         reader: {
             type: 'json',
             root: 'users'
         }
     },
     autoLoad: true
 });

In the example above we configured an AJAX proxy to load data from the url '/users.json'. We told our Proxy to use a JsonReader to parse the response from the server into Model object - see the docs on JsonReader for details.

Inline data

Stores can also load data inline. Internally, Store converts each of the objects we pass in as data into Model instances:

 Ext.create('Ext.data.Store', {
     model: 'User',
     data : [
         {firstName: 'Ed',    lastName: 'Spencer'},
         {firstName: 'Tommy', lastName: 'Maintz'},
         {firstName: 'Aaron', lastName: 'Conran'},
         {firstName: 'Jamie', lastName: 'Avins'}
     ]
 });

Loading inline data using the method above is great if the data is in the correct format already (e.g. it doesn't need to be processed by a reader). If your inline data requires processing to decode the data structure, use a MemoryProxy instead (see the MemoryProxy docs for an example).

Additional data can also be loaded locally using add.

Dynamic Loading

Stores can be dynamically updated by calling the load method:

store.load({
    params: {
        group: 3,
        type: 'user'
    },
    callback: function(records, operation, success) {
        // do something after the load finishes
    },
    scope: this
});

Here a bunch of arbitrary parameters is passed along with the load request and a callback function is set up to do something after the loading is over.

Loading Nested Data

Applications often need to load sets of associated data - for example a CRM system might load a User and her Orders. Instead of issuing an AJAX request for the User and a series of additional AJAX requests for each Order, we can load a nested dataset and allow the Reader to automatically populate the associated models. Below is a brief example, see the Ext.data.reader.Reader intro docs for a full explanation:

 var store = Ext.create('Ext.data.Store', {
     autoLoad: true,
     model: "User",
     proxy: {
         type: 'ajax',
         url: 'users.json',
         reader: {
             type: 'json',
             root: 'users'
         }
     }
 });

Which would consume a response like this:

 {
     "users": [{
         "id": 1,
         "name": "Ed",
         "orders": [{
             "id": 10,
             "total": 10.76,
             "status": "invoiced"
        },{
             "id": 11,
             "total": 13.45,
             "status": "shipped"
        }]
     }]
 }

See the Ext.data.reader.Reader intro docs for a full explanation.

Filtering and Sorting

Stores can be sorted and filtered - in both cases either remotely or locally. The sorters and filters are held inside MixedCollection instances to make them easy to manage. Usually it is sufficient to either just specify sorters and filters in the Store configuration or call sort or filter:

 var store = Ext.create('Ext.data.Store', {
     model: 'User',
     sorters: [{
         property: 'age',
         direction: 'DESC'
     }, {
         property: 'firstName',
         direction: 'ASC'
     }],

     filters: [{
         property: 'firstName',
         value: /Ed/
     }]
 });

The new Store will keep the configured sorters and filters in the MixedCollection instances mentioned above. By default, sorting and filtering are both performed locally by the Store - see remoteSort and remoteFilter to allow the server to perform these operations instead.

Filtering and sorting after the Store has been instantiated is also easy. Calling filter adds another filter to the Store and automatically filters the dataset (calling filter with no arguments simply re-applies all existing filters). Note that by default sortOnFilter is set to true, which means that your sorters are automatically reapplied if using local sorting.

store.filter('eyeColor', 'Brown');

Change the sorting at any time by calling sort:

store.sort('height', 'ASC');

Note that all existing sorters will be removed in favor of the new sorter data (if sort is called with no arguments, the existing sorters are just reapplied instead of being removed). To keep existing sorters and add new ones, just add them to the MixedCollection:

store.sorters.add(new Ext.util.Sorter({
    property : 'shoeSize',
    direction: 'ASC'
}));

store.sort();

Registering with StoreManager

Any Store that is instantiated with a storeId will automatically be registered with the StoreManager. This makes it easy to reuse the same store in multiple views:

//this store can be used several times
Ext.create('Ext.data.Store', {
    model: 'User',
    storeId: 'usersStore'
});

new Ext.List({
    store: 'usersStore',
    //other config goes here
});

new Ext.view.View({
    store: 'usersStore',
    //other config goes here
});

Allows the Store to prefetch and cache in a page cache, pages of Records, and to then satisfy loading requirements from this page cache.

To use buffered Stores, initiate the process by loading the first page. The number of rows rendered are determined automatically, and the range of pages needed to keep the cache primed for scrolling is requested and cached. Example:

myStore.loadPage(1); // Load page 1

A PagingScroller is instantiated which will monitor the scrolling in the grid, and refresh the view's rows from the page cache as needed. It will also pull new data into the page cache when scrolling of the view draws upon data near either end of the prefetched data.

The margins which trigger view refreshing from the prefetched data are Ext.grid.PagingScroller.numFromEdge, Ext.grid.PagingScroller.leadingBufferZone and Ext.grid.PagingScroller.trailingBufferZone.

The margins which trigger loading more data into the page cache are, leadingBufferZone and trailingBufferZone.

By default, only 5 pages of data are cached in the page cache, with pages "scrolling" out of the buffer as the view moves down through the dataset. Setting this value to zero means that no pages are ever scrolled out of the page cache, and that eventually the whole dataset may become present in the page cache. This is sometimes desirable as long as datasets do not reach astronomical proportions.

Selection state may be maintained across page boundaries by configuring the SelectionModel not to discard records from its collection when those Records cycle out of the Store's primary collection. This is done by configuring the SelectionModel like this:

selModel: {
    pruneRemoved: false
}

Defaults to: false

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
            fn: function(){ console.log('dblclick body'); }
        }

: Number
The number of records considered to form a 'page'. ...

The number of records considered to form a 'page'. This is used to power the built-in paging using the nextPage and previousPage functions when the grid is paged using a PagingScroller Defaults to 25.

If this Store is buffered, pages are loaded into a page cache before the Store's data is updated from the cache. The pageSize is the number of rows loaded into the cache in one request. This will not affect the rendering of a buffered grid, but a larger page size will mean fewer loads.

In a buffered grid, scrolling is monitored, and the page cache is kept primed with data ahead of the direction of scroll to provide rapid access to data when scrolling causes it to be required. Several pages in advance may be requested depending on various parameters.

It is recommended to tune the pageSize, trailingBufferZone and leadingBufferZone configurations based upon the conditions pertaining in your deployed application.

The provided SDK example examples/grid/infinite-scroll-grid-tuner.html can be used to experiment with different settings including simulating Ajax latency.

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:

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:

( 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.

      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
      });
      

      Defaults to: false

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();

          Available since: 4.0.0

          This method has been deprecated

          as of 4.1. Use callParent instead.

          Parameters

          • args : Array/Arguments

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

          Returns

          • Object

            Returns the result of calling the overridden method

          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: 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

          ( args ) : Objectprotected
          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".

                        Parameters

                        • fn : Function

                          The function to call. The Record is passed as the first parameter. Returning false aborts and exits the iteration.

                        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');
                                }
                            }
                        });
                        

                        Available since: 3.4.0

                        Parameters

                        • eventNames : String/String[]

                          The event name to bubble, or an Array of event names.

                        Ext.data.Store
                        view source
                        ( filters, [value] )
                        Filters the loaded set of records by a given set of filters. ...

                        Filters the loaded set of records by a given set of filters.

                        By default, the passed filter(s) are added to the collection of filters being used to filter this Store.

                        To remove existing filters before applying a new set of filters use

                        // Clear the filter collection without updating the UI
                        store.clearFilter(true);
                        

                        see clearFilter.

                        Alternatively, if filters are configured with an id, then existing filters store may be replaced by new filters having the same id.

                        Filtering by single field:

                        store.filter("email", /\.com$/);
                        

                        Using multiple filters:

                        store.filter([
                            {property: "email", value: /\.com$/},
                            {filterFn: function(item) { return item.get("age") > 10; }}
                        ]);
                        

                        Using Ext.util.Filter instances instead of config objects (note that we need to specify the root config option in this case):

                        store.filter([
                            Ext.create('Ext.util.Filter', {property: "email", value: /\.com$/, root: 'data'}),
                            Ext.create('Ext.util.Filter', {filterFn: function(item) { return item.get("age") > 10; }, root: 'data'})
                        ]);
                        

                        When store is filtered, most of the methods for accessing store data will be working only within the set of filtered records. Two notable exceptions are queryBy and getById.

                        Parameters

                        • filters : Object[]/Ext.util.Filter[]/String

                          The set of filters to apply to the data. These are stored internally on the store, but the filtering itself is done on the Store's MixedCollection. See MixedCollection's filter method for filter syntax. Alternatively, pass in a property string

                        • value : String (optional)

                          value to filter by (only if using a property string as the first argument)

                                      This is used recursively to gather the records into the configured Groupers. The data MUST have been sorted for this to work properly (see getGroupData and getGroupsForGrouper) Most of the work is done by getGroupsForGrouper - this function largely just handles the recursion.

                                                        callback: function(records, operation, success) {
                                                            // the operation object
                                                            // contains all of the details of the load operation
                                                            console.log(records);
                                                        }
                                                    });
                                                    

                                                    If the callback scope does not need to be set, a function can simply be passed:

                                                          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)

                                                        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.

                                                            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
                                                            });
                                                            

                                                            Defaults to: false

                                                        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();
                                                          
                                                        Attached as the 'complete' event listener to a proxy's Batch object. ...

                                                            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.

                                                              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'.

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