</span> * @class Ext.data.JsonPStore
 * @extends Ext.data.Store
 * &lt;p&gt;Small helper class to make creating {@link Ext.data.Store}s from different domain JSON data easier.
 * A JsonPStore will be automatically configured with a {@link Ext.data.reader.Json} and a {@link Ext.data.proxy.JsonP JsonPProxy}.&lt;/p&gt;
 * &lt;p&gt;A store configuration would be something like:&lt;pre&gt;&lt;code&gt;
var store = new Ext.data.JsonPStore({
    // store configs
    storeId: 'myStore',

    // proxy configs
    url: 'get-images.php',

    // reader configs
    root: 'images',
    idProperty: 'name',
    fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
});
 * &lt;/code&gt;&lt;/pre&gt;&lt;/p&gt;
 * &lt;p&gt;This store is configured to consume a returned object of the form:&lt;pre&gt;&lt;code&gt;
stcCallback({
    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)}
    ]
})
 * &lt;/code&gt;&lt;/pre&gt;
 * &lt;p&gt;Where stcCallback is the callback name passed in the request to the remote domain. See {@link Ext.data.proxy.JsonP JsonPProxy}
 * for details of how this works.&lt;/p&gt;
 * An object literal of this form could also be used as the {@link #cfg-data} config option.&lt;/p&gt;
 * @xtype jsonpstore
