10 * @class Ext.data.JsonStore
11 * @extends Ext.data.Store
12 * Small helper class to make creating Stores for remotely-loaded JSON data easier. JsonStore is pre-configured
13 * with a built-in {@link Ext.data.HttpProxy} and {@link Ext.data.JsonReader}.  If you require some other proxy/reader
14 * combination then you'll have to create a basic {@link Ext.data.Store} configured as needed.<br/>
15<pre><code>
16var store = new Ext.data.JsonStore({
17    url: 'get-images.php',
18    root: 'images',
19    fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
20});
21</code></pre>
22 * This would consume a returned object of the form:
23<pre><code>
24{
25    images: [
26        {name: 'Image one', url:'/GetImage.php?id=1', size:46.5, lastmod: new Date(2007, 10, 29)},
27        {name: 'Image Two', url:'/GetImage.php?id=2', size:43.2, lastmod: new Date(2007, 10, 30)}
28    ]
29}
30</code></pre>
31 * An object literal of this form could also be used as the {@link #data} config option.
32 * <b>Note: Although they are not listed, this class inherits all of the config options of Store,
33 * JsonReader.</b>
34 * @cfg {String} url  The URL from which to load data through an HttpProxy. Either this
35 * option, or the {@link #data} option must be specified.
36 * @cfg {Object} data  A data object readable by this object's JsonReader. Either this
37 * option, or the {@link #url} option must be specified.
38 * @cfg {Array} fields  Either an Array of field definition objects as passed to
39 * {@link Ext.data.Record#create}, or a {@link Ext.data.Record Record} constructor created using {@link Ext.data.Record#create}.<br>
40 * <p>This config is used to create the <tt>recordType</tt> parameter to the {@link Ext.data.JsonReader#JsonReader JsonReader}
41 * constructor that is implicitly called, and creates the {@link Ext.data.Record Record definition} used by the Store.
42 * @constructor
43 * @param {Object} config
