<pre><code><i>// Basic request</i>
Ext.Ajax.request({
   url: <em>'foo.php'</em>,
   success: someFn,
   failure: otherFn,
   headers: {
       <em>'my-header'</em>: <em>'foo'</em>
   },
   params: { foo: <em>'bar'</em> }
});

<i>// Simple ajax form submission</i>
Ext.Ajax.request({
    form: <em>'some-form'</em>,
    params: <em>'foo=bar'</em>
});

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

<i>// Global Ajax events can be handled on every request!</i>
Ext.Ajax.on(<em>'beforerequest'</em>, <b>this</b>.showSpinner, <b>this</b>);</code></pre><br><br><i>This class is a singleton and cannot be created directly.</i>        </div>
