9 | * @extends Ext.data.Store |
---|
10 | * <p>Small helper class to make creating {@link Ext.data.Store}s from JSON data easier. |
---|
11 | * A JsonStore will be automatically configured with a {@link Ext.data.JsonReader}.</p> |
---|
12 | * <p>A store configuration would be something like:<pre><code> |
---|
13 | var store = new Ext.data.JsonStore({ |
---|
14 | // store configs |
---|
15 | autoDestroy: true, |
---|
16 | url: 'get-images.php', |
---|
17 | storeId: 'myStore', |
---|
18 | // reader configs |
---|
19 | root: 'images', |
---|
20 | idProperty: 'name', |
---|
21 | fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}] |
---|
22 | }); |
---|
23 | * </code></pre></p> |
---|
24 | * <p>This store is configured to consume a returned object of the form:<pre><code> |
---|
25 | { |
---|
26 | images: [ |
---|
27 | {name: 'Image one', url:'/GetImage.php?id=1', size:46.5, lastmod: new Date(2007, 10, 29)}, |
---|
28 | {name: 'Image Two', url:'/GetImage.php?id=2', size:43.2, lastmod: new Date(2007, 10, 30)} |
---|
29 | ] |
---|
30 | } |
---|
31 | * </code></pre> |
---|
32 | * An object literal of this form could also be used as the {@link #data} config option.</p> |
---|
33 | * <p><b>*Note:</b> Although not listed here, this class accepts all of the configuration options of |
---|
34 | * <b>{@link Ext.data.JsonReader JsonReader}</b>.</p> |
---|
35 | * @constructor |
---|
36 | * @param {Object} config |
---|
37 | * @xtype jsonstore |
