title: Retrieving entire json array as a string
body: <p>I am using fine uploader to pass params like this</p>
  
  <pre><code>callbacks: {
      onSubmit: function(id, fileName) {
          this.setParams({
              a: 'adm',
              b: '126',
              c: {
                  fileID: id,
                  path:'',
                  name:'',
                  originalName: fileName
              }
          });
      }
  }
  </code></pre>
  
  <p>On the server side (in nodejs) I would like to retrieve the entire array at once
  with something like </p>
  
  <pre><code>req.body[c]
  </code></pre>
  
  <p>to get the string</p>
  
  <pre><code>{
      fileID: id,
          path:'',
      name:'',
      originalName: fileName
  }
  </code></pre>
  
  <p>but c comes out as a javascript array so it seems I would have to pick each subkey one by one with</p>
  
  <pre><code>req.body[c['fileID']], ...
  </code></pre>
  
  <p>Is there a way in javascript/fine uploader of getting the entire array by its name?</p>
  
  <p>Or at least an easier way to loop through all the keys of the array?</p>
