/**
|
|
* @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.<br/>
|
|
<pre><code>
|
|
var store = new Ext.data.JsonStore({
|
|
url: 'get-images.php',
|
|
root: 'images',
|
|
fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
|
|
});
|
|
</code></pre>
|
|
* This would 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.
|
|
* <b>Note: Although they are not listed, this class inherits all of the config options of Store,
|
|
* JsonReader.</b>
|
|
* @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}.<br>
|
|
* <p>This config is used to create the <tt>recordType</tt> 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
