title: ExtJS Textarea - autosave contents on user input
body: <p>I'm an ExtJS newbie and need to send the contents of a ExtJS Textarea to the backend server for saving (autosave facility) as the user types in. Is there a way to do it. I've currently registered a keyup listener to collect the input value as shown below:</p>
  
  <pre class="lang-js prettyprint-override"><code>items: [{
      xtype: 'textarea',
      id: 'notes',
      anchor: '100%',
      height: 270,
      msgTarget: 'under',
      fieldLabel: 'Note',
      enableKeyEvents: true,
      listeners: {
          'keyup': function(textarea, event) {
              var v= textarea.getValue();
              Ext.Ajax.request({
                  url: 'buffernote.action',
                  params: {value: v}
              })
          }
      }
  }
  }]
  </code></pre>
  
  <p>Am I in the right direction?</p>
