10 * @class Ext.data.JsonStore
\r
11 * @extends Ext.data.Store
\r
12 * Small helper class to make creating Stores for remotely-loaded JSON data easier. JsonStore is pre-configured
\r
13 * with a built-in {@link Ext.data.HttpProxy} and {@link Ext.data.JsonReader}. If you require some other proxy/reader
\r
14 * combination then you'll have to create a basic {@link Ext.data.Store} configured as needed.<br/>
\r
16 var store = new Ext.data.JsonStore({
\r
17 url: 'get-images.php',
\r
19 fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
\r
22 * This would consume a returned object of the form:
\r
26 {name: 'Image one', url:'/GetImage.php?id=1', size:46.5, lastmod: new Date(2007, 10, 29)},
\r
27 {name: 'Image Two', url:'/GetImage.php?id=2', size:43.2, lastmod: new Date(2007, 10, 30)}
\r
31 * An object literal of this form could also be used as the {@link #data} config option.
\r
32 * <b>Note: Although they are not listed, this class inherits all of the config options of Store,
\r
34 * @cfg {String} url The URL from which to load data through an HttpProxy. Either this
\r
35 * option, or the {@link #data} option must be specified.
\r
36 * @cfg {Object} data A data object readable by this object's JsonReader. Either this
\r
37 * option, or the {@link #url} option must be specified.
\r
38 * @cfg {Array} fields Either an Array of field definition objects as passed to
\r
39 * {@link Ext.data.Record#create}, or a {@link Ext.data.Record Record} constructor created using {@link Ext.data.Record#create}.<br>
\r
40 * <p>This config is used to create the <tt>recordType</tt> parameter to the {@link Ext.data.JsonReader#JsonReader JsonReader}
\r
41 * constructor that is implicitly called, and creates the {@link Ext.data.Record Record definition} used by the Store.
\r
43 * @param {Object} config
\r
45 Ext.data.JsonStore = function(c){
\r
47 * @cfg {Ext.data.DataReader} reader @hide
\r
50 * @cfg {Ext.data.DataProxy} proxy @hide
\r
52 Ext.data.JsonStore.superclass.constructor.call(this, Ext.apply(c, {
\r
53 proxy: c.proxy || (!c.data ? new Ext.data.HttpProxy({url: c.url}) : undefined),
