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.

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 registed 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
});

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'); }

Parameters

Returns

( eventName, fn, [scope], [options] )
Appends an event handler to this object. ...

Appends an event handler to this object.

Available since: 1.1.0

Parameters

  • eventName : String

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

  • fn : Function

    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.

    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 : 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'
          }
      });
      

    Combining Options

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

    A delayed, one-time listener.

    myPanel.on('hide', this.handleClick, this, {
        single: true,
        delay: 100
    });
    

    Attaching multiple handlers in 1 call

    The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

    myGridPanel.on({
        cellClick: this.onCellClick,
        mouseover: this.onMouseOver,
        mouseout: this.onMouseOut,
        scope: this // Important. Ensure "this" is correct during handler execution
    });
    

    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}
    });

                      Parameters

                      • fn : Function

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

                      • scope : Object (optional)

                        The scope (this reference) in which the function is executed. Defaults to the current Record in 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.override(Ext.form.field.Base, {
                          //  Add functionality to Field's initComponent to enable the change event to bubble
                          initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {
                              this.enableBubble('change');
                          }),
                      
                          //  We know that we want Field's events to bubble directly to the FormPanel.
                          getBubbleTarget : function() {
                              if (!this.formPanel) {
                                  this.formPanel = this.findParentByType('form');
                              }
                              return this.formPanel;
                          }
                      });

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

                      Filtering by single field:

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

                                Returns the string to group on for a given model instance. The default implementation of this method returns the model's groupField, but this can be overridden to group by an arbitrary string. For example, to group by the first letter of a model's 'name' field, use the following code:

                                Ext.create('Ext.data.Store', {
                                    groupDir: 'ASC',

                                  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.

                                              Loads data into the Store via the configured proxy. This uses the Proxy to make an asynchronous call to whatever storage backend the Proxy uses, automatically adding the retrieved instances into the Store and calling an optional callback if required. Example usage:

                                              store.load({
                                                  scope   : this,
                                                  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:

                                              store.load(function(records, operation, success) {
                                                  console.log('loaded records');
                                              });

                                                Using this method 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 data requires processing to decode the data structure, use a MemoryProxy instead.

                                                          • eventName : String

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

                                                          • fn : Function

                                                            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.

                                                            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 : 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'
                                                                  }
                                                              });
                                                              

                                                            Combining Options

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

                                                            A delayed, one-time listener.

                                                            myPanel.on('hide', this.handleClick, this, {
                                                                single: true,
                                                                delay: 100
                                                            });
                                                            

                                                            Attaching multiple handlers in 1 call

                                                            The method also allows for a single argument to be passed which is a config object containing properties which specify multiple events. For example:

                                                            myGridPanel.on({
                                                                cellClick: this.onCellClick,
                                                                mouseover: this.onMouseOver,
                                                                mouseout: this.onMouseOut,
                                                                scope: this // Important. Ensure "this" is correct during handler execution
                                                            });
                                                            

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

                                                          Attached as the 'complete' event listener to a proxy's Batch object. Iterates over the batch operations and updates the Store's internal data MixedCollection.
