Class Ext.Ajax

Package:Ext
Defined In:Connection.js
Class:Ajax
Extends:Connection

The global Ajax request class that provides a simple way to make Ajax requests -with maximum flexibility.

-

Since Ext.Ajax is a singleton, you can set common properties/events for it once -and override them at the request function level only if necessary.

-

Common Properties you may want to set are:

-
// Default headers to pass in every request
-Ext.Ajax.defaultHeaders = {
-    'Powered-By': 'Ext'
-};
-

-

Common Events you may want to set are:

-
// Example: show a spinner during all Ajax requests
-Ext.Ajax.on('beforerequest', this.showSpinner, this);
-Ext.Ajax.on('requestcomplete', this.hideSpinner, this);
-Ext.Ajax.on('requestexception', this.hideSpinner, this);
-

-

An example request:

-
// Basic request
-Ext.Ajax.request({
-   url: 'foo.php',
-   success: someFn,
-   failure: otherFn,
-   headers: {
-       'my-header': 'foo'
-   },
-   params: { foo: 'bar' }
-});
-
-// Simple ajax form submission
-Ext.Ajax.request({
-    form: 'some-form',
-    params: 'foo=bar'
-});
-



This class is a singleton and cannot be created directly.
