<div id="cls-Ext.data.JsonStore"></div>/**
* @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, {
<div id="cfg-Ext.data.JsonStore-reader"></div>/**
* @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)
}));
}
});
Ext.reg('jsonstore', Ext.data.JsonStore);</pre>
