/** * A singleton instance of an `{@link Ext.data.Connection}`. This class is used to * communicate with your server side code. It can be used as follows: * * Ext.Ajax.request({ * url: 'ajax_demo/sample.json', * * success: function(response, opts) { * var obj = Ext.decode(response.responseText); * console.dir(obj); * }, * * failure: function(response, opts) { * console.log('server-side failure with status code ' + response.status); * } * }); * * Default options for all requests can be set by changing a property on the Ext.Ajax class: * * Ext.Ajax.setTimeout(60000); // 60 seconds * * Any options specified in the request method for the Ajax request will override any * defaults set on the `Ext.Ajax` singleton. In the code sample below, the timeout for the * request will be 60 seconds. * * Ext.Ajax.setTimeout(120000); // 120 seconds * * Ext.Ajax.request({ * url: 'page.aspx', * timeout: 60000 * }); * * In general, this class will be used for all Ajax requests in your application. The main * reason for creating a separate `{@link Ext.data.Connection}` is for a series of * requests that share common settings that are different to all other requests in the * application. */Ext.define('Ext.Ajax', { extend: 'Ext.data.Connection', singleton: true, /** * @cfg {Object} extraParams * @hide */ /** * @cfg {Object} defaultHeaders * @hide */ /** * @cfg {String} method * @hide */ /** * @cfg {Number} timeout * @hide */ /** * @cfg {Boolean} autoAbort * @hide */ /** * @cfg {Boolean} disableCaching * @hide */ /** * @property {Boolean} disableCaching * True to add a unique cache-buster param to GET requests.
