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

- * @cfg {Ext.data.DataReader} reader @hide

- constructor: function(config){
- Ext.data.JsonStore.superclass.constructor.call(this, Ext.apply(config, {
- reader: new Ext.data.JsonReader(config)
- }));
- }
- });
