JsonStore.js

NOTE This is a private utility class for internal use by the framework. Don't rely on its existence.

Small helper class to make creating Ext.data.Stores from JSON data easier.\nA JsonStore will be automatically configured with a Ext.data.reader.Json.

\n\n\n\n\n

A store configuration would be something like:

\n\n\n\n\n
var store = new Ext.data.JsonStore({\n    // store configs\n    autoDestroy: true,\n    storeId: 'myStore',\n\n    proxy: {\n        type: 'ajax',\n        url: 'get-images.php',\n        reader: {\n            type: 'json',\n            root: 'images',\n            idProperty: 'name'\n        }\n    },\n\n    //alternatively, a Ext.data.Model name can be given (see Ext.data.Store for an example)\n    fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]\n});\n
\n\n\n\n\n

This store is configured to consume a returned object of the form:\n

{\n    images: [\n        {name: 'Image one', url:'/GetImage.php?id=1', size:46.5, lastmod: new Date(2007, 10, 29)},\n        {name: 'Image Two', url:'/GetImage.php?id=2', size:43.2, lastmod: new Date(2007, 10, 30)}\n    ]\n}\n
\n\n

An object literal of this form could also be used as the data config option.

This may be used in place of specifying a model configuration. The fields should be a\nset of Ext.data.Field configuration objects. The store will automatically create a Ext.data.Model\nwith these fields. In general this configuration option should be avoided, it exists for the purposes of\nbackwards compatibility. For anything more complicated, such as specifying a particular id property or\nassocations, a Ext.data.Model should be defined and specified for the model\nconfig.

DOM events from Ext JS Components

\n\n

While some Ext JS Component classes export selected DOM events (e.g. \"click\", \"mouseover\" etc), this is usually\nonly done when extra value can be added. For example the DataView's itemclick event passing the node clicked on. To access DOM events directly from a\nchild element of a Component, we need to specify the element option to identify the Component property to add a\nDOM listener to:

\n\n
new Ext.panel.Panel({\n    width: 400,\n    height: 200,\n    dockedItems: [{\n        xtype: 'toolbar'\n    }],\n    listeners: {\n        click: {\n            element: 'el', //bind to the underlying el property on the panel\n            fn: function(){ console.log('click el'); }\n        },\n        dblclick: {\n            element: 'body', //bind to the underlying body property on the panel\n            fn: function(){ console.log('dblclick body'); }\n        }\n    }\n});\n

view source
( String eventName, Function fn, [Object scope], [Object options] )
Appends an event handler to this object. ...

Appends an event handler to this object.

\n

Parameters

  • eventName : String

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

    \n\n
  • fn : Function

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

    \n\n
  • scope : Object (optional)

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

    \n\n
  • options : Object (optional)

    An object containing handler configuration.

    \n\n\n\n\n

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

    \n\n\n\n\n

    This object may contain any of the following properties:

    \n\n\n\n\n
      \n

    • scope : Object

      \n\n

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

      • \n

    • delay : Number

      \n\n

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

      • \n

    • single : Boolean

      \n\n

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

      • \n

    • buffer : Number

      \n\n

      Causes the handler to be scheduled to run in an Ext.util.DelayedTask delayed by the specified number of\nmilliseconds. If the event fires again within that time, the original handler is not invoked, but the new\nhandler is scheduled in its place.

      • \n

    • target : Observable

      \n\n

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

      • \n

    • element : String

      \n\n

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

      \n\n

      This option is useful during Component construction to add DOM event listeners to elements of\nComponents which will exist only after the Component is rendered.\nFor example, to add a click listener to a Panel's body:

      \n\n
      new Ext.panel.Panel({\n    title: 'The title',\n    listeners: {\n        click: this.handlePanelClick,\n        element: 'body'\n    }\n});\n
      • \n
    \n\n\n\n\n

    Combining Options

    \n\n\n\n\n

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

    \n\n\n\n\n

    A delayed, one-time listener.

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

    Attaching multiple handlers in 1 call

    \n\n\n\n\n

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

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

    One can also specify options for each event handler separately:

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

Enables events fired by this Observable to bubble up an owner hierarchy by calling this.getBubbleTarget() if\npresent. There is no implementation in the Observable base class.

\n\n

This is commonly used by Ext.Components to bubble events to owner Containers.\nSee Ext.Component.getBubbleTarget. The default implementation in Ext.Component returns the\nComponent's immediate owner. But if a known target is required, this can be overridden to access the\nrequired target more quickly.

\n\n

Example:

\n\n
Ext.override(Ext.form.field.Base, {\n    //  Add functionality to Field's initComponent to enable the change event to bubble\n    initComponent : Ext.Function.createSequence(Ext.form.field.Base.prototype.initComponent, function() {\n        this.enableBubble('change');\n    }),\n\n    //  We know that we want Field's events to bubble directly to the FormPanel.\n    getBubbleTarget : function() {\n        if (!this.formPanel) {\n            this.formPanel = this.findParentByType('form');\n        }\n        return this.formPanel;\n    }\n});\n\nvar myForm = new Ext.formPanel({\n    title: 'User Details',\n    items: [{\n        ...\n    }],\n    listeners: {\n        change: function() {\n            // Title goes red if form has been modified.\n            myForm.header.setStyle('color', 'red');\n        }\n    }\n});\n
\n

Parameters

  • events : String/String[]

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

Ext.data.Store
view source
( Object[]/Ext.util.Filter[]/String filters, [String 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.

\n\n

Filtering by single field:

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

Using multiple filters:

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

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

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

      This option is useful during Component construction to add DOM event listeners to elements of\nComponents which will exist only after the Component is rendered.\nFor example, to add a click listener to a Panel's body:

      \n\n
      new Ext.panel.Panel({\n    title: 'The title',\n    listeners: {\n        click: this.handlePanelClick,\n        element: 'body'\n    }\n});\n
      • \n
    \n\n\n\n\n

    Combining Options

    \n\n\n\n\n

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

    \n\n\n\n\n

    A delayed, one-time listener.

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

    Attaching multiple handlers in 1 call

    \n\n\n\n\n

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

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

    One can also specify options for each event handler separately:

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

Parameters

Returns

Ext.util.Sortable
view source
( String/Ext.util.Sorter[] sorters, String direction ) : Ext.util.Sorter[]
Sorts the data in the Store by one or more of its properties. ...

Sorts the data in the Store by one or more of its properties. Example usage:

\n\n
//sort by a single field\nmyStore.sort('myField', 'DESC');\n\n//sorting by multiple fields\nmyStore.sort([\n    {\n        property : 'age',\n        direction: 'ASC'\n    },\n    {\n        property : 'name',\n        direction: 'DESC'\n    }\n]);\n
\n\n

Internally, Store converts the passed arguments into an array of Ext.util.Sorter instances, and delegates\nthe actual sorting to its internal Ext.util.MixedCollection.

\n\n

When passing a single string argument to sort, Store maintains a ASC/DESC toggler per field, so this code:

\n\n
store.sort('myField');\nstore.sort('myField');\n
\n\n

Is equivalent to this code, because Store handles the toggling automatically:

\n\n
store.sort('myField', 'ASC');\nstore.sort('myField', 'DESC');\n
\n

Parameters

  • sorters : String/Ext.util.Sorter[]

    Either a string name of one of the fields in this Store's configured\nModel, or an array of sorter configurations.
