title: prototype JSON to Object
body: <p>The following is part of a JSON string returned from the server:</p>
  
  <pre><code>{
    col1: { 
            caption: 'Workspace',
            combodata: {
                         c_0: {
                                id: 0,
                                value: 'Filter...'
                              },
                         c_1: {
                                id: 1, 
                                value: 'Tax'
                              },
                         c_2: {
                                id: 2, 
                                value: 'HR'
                              }
                        }
          }
  }
  </code></pre>
  
  <p>After eval, I can access <code>.caption</code>, and <code>.combodata</code> is visible in Firebug as an object, with c_0 and c_1 visible as objects inside <code>.combodata</code>, with id and value in both c_0 and c_1.</p>
  
  <p>How do I step through each object in <code>.combodata</code>? I tried <code>.combodata.each(c)</code>, but that throws an exception. I won't know the names of the objects in <code>.combodata</code> during run time.</p>
