Class Ext.Updater

Package:Ext
Defined In:UpdateManager.js
Class:Updater
Extends:Observable
Provides AJAX-style update capabilities for Element objects. Updater can be used to update an Ext.Element once, or you can use startAutoRefresh to set up an auto-updating Element on a specific interval.

Usage:
var el = Ext.get("foo"); // Get Ext.Element object
var mgr = el.getUpdater();
mgr.update({
        url: "http://myserver.com/index.php",
        params: {
            param1: "foo",
            param2: "bar"
        }
});
...
mgr.formUpdate("myFormId", "http://myserver.com/index.php");

// or directly (returns the same Updater instance) var mgr = new Ext.Updater("myElementId"); mgr.startAutoRefresh(60, "http://myserver.com/index.php"); mgr.on("update", myFcnNeedsToKnow);
// short handed call directly from the element object Ext.get("foo").load({ url: "bar.php", scripts: true, params: "param1=foo&param2=bar", text: "Loading Foo..." });
