title: ExtJS - Loop through CheckBoxGroup
body: <p>I would like to get all of the checked items in a checkboxgroup that is part of a formpanel. Ultimately they would be saved back to database as a string, comma separated value format.</p>
  
  <p>Thanks for any guidance or assistance you can provide.</p>
  
  <p>Here is how I have my group defined:</p>
  
  <pre><code>new Ext.form.CheckboxGroup({
              id: 'newId',
              fieldLabel: 'Group A',
              name: 'broker',
              allowBlank: false,
              columns: 1,
              items: [{
                  boxLabel: 'All',
                  name: 'all',
                  id: 'null'
              },
              {
                  boxLabel: 'FS',
                  name: 'fs',
                  id: '1'
              },
              {
                  boxLabel: 'Royal A',
                  name: 'ra',
                  id: '2'
              },
              {
                  boxLabel: 'Point',
                  name: 'sp',
                  id: '6'
              }]
          })
  </code></pre>
