/**
* @class Ext.data.JsonStore
* @extends Ext.data.Store
* Small helper class to make creating Stores for remotely-loaded JSON data easier. JsonStore is pre-configured
* with a built-in {@link Ext.data.HttpProxy} and {@link Ext.data.JsonReader}. If you require some other proxy/reader
* combination then you'll have to create a basic {@link Ext.data.Store} configured as needed.
var store = new Ext.data.JsonStore({
url: 'get-images.php',
root: 'images',
fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
});
* This would consume a returned object of the form:
{
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)}
]
}
* An object literal of this form could also be used as the {@link #data} config option.
* Note: Although they are not listed, this class inherits all of the config options of Store,
* JsonReader.
* @cfg {String} url The URL from which to load data through an HttpProxy. Either this
* option, or the {@link #data} option must be specified.
* @cfg {Object} data A data object readable by this object's JsonReader. Either this
* option, or the {@link #url} option must be specified.
* @cfg {Array} fields Either an Array of field definition objects as passed to
* {@link Ext.data.Record#create}, or a {@link Ext.data.Record Record} constructor created using {@link Ext.data.Record#create}.This config is used to create the recordType parameter to the {@link Ext.data.JsonReader#JsonReader JsonReader} * constructor that is implicitly called, and creates the {@link Ext.data.Record Record definition} used by the Store. * @constructor * @param {Object} config */ Ext.data.JsonStore = function(c){ /** * @cfg {Ext.data.DataReader} reader @hide */ /** * @cfg {Ext.data.DataProxy} proxy @hide */ Ext.data.JsonStore.superclass.constructor.call(this, Ext.apply(c, { proxy: c.proxy || (!c.data ? new Ext.data.HttpProxy({url: c.url}) : undefined), reader: new Ext.data.JsonReader(c, c.fields) })); }; Ext.extend(Ext.data.JsonStore, Ext.data.Store);
