title: parsing JSON object with Jquery problem
body: <p>Hi I am trying to parse the following bit of json with Jquery so far I can get everything out of the results that I want apart from one crucial piece of information the performance tags.</p>
  
  <p>Each json result is wrapped in an event tag and then within this there is info like time and date etc formatted in the following way </p>
  
  <pre><code>"location": {
                  "lng": -0.1187418,
                  "city": "London, UK",
                  "lat": 51.4681089
              },
              "start": {
                  "time": "19:30:00",
                  "datetime":"2010-02-16T19:30:00+0000",
                  "date": "2010-02-16"
              },
  </code></pre>
  
  <p>I have managed to loop through this and parse it to html. However there is one set of tags for 'performance' that are formatted differently.</p>
  
  <pre><code>"performance": [{
                  {
                      "artist": {
                           "uri": "http://www.songkick.com/artists/288696-vampire-weekend",
                           "displayName": "Vampire Weekend",
                           "id": 288696,
                           "identifier": [{"mbid": "af37c51c-0790-4a29-b995-456f98a6b8c9"}]
                      }
                      "displayName": "Vampire Weekend",
                      "billingIndex": 1,
                      "id": 5380281,
                      "billing": "headline"
                  }
              }],
  </code></pre>
  
  <p>now in my for loop i am running the following code which displays the performance information in the console. </p>
  
  <pre><code>var events = data.resultsPage.results.event;
  for (var i = 0, l = events.length; i &lt; l; i++) {
  
  console.log(events[i].performance); }
  </code></pre>
  
  <p>However when i try to go into the structure like i have been with the other elements I get returned undefined i.e</p>
  
  <pre><code>console.log(events[i].performance.displayName);
  </code></pre>
  
  <p>Do I have to do this in a different way because of the use of the [ ] brackets in the performance tag in the Json?</p>
  
  <p>Thanks in advance</p>
