title: Using Javascript to scan JSON data from youtube API
body: <p>I am trying my hand at searching youtube with the youtube API via Javascript, and as per the google docs on the matter: </p>
  
  <pre><code>&lt;div id="agenda"&gt;&lt;/div&gt;
  
  &lt;script&gt;
    function listEvents(root) {
      var feed = root.feed;
      var entries = feed.entry || [];
      var html = ['&lt;ul&gt;'];
  
  
      for (var i = 0; i &lt; entries.length; ++i) {
        var entry = entries[i];
        console.log(entry);
        var title = (entry.title.type == 'html') ? entry.title.$t : escape(entry.title.$t);
        var start = (entry['gd$when']) ? entry['gd$when'][0].startTime : "";
        //var id = id.video;  
        //alert(id);
  
        html.push('&lt;li&gt;', start, ' ', title, '&lt;/li&gt;');
      }
  
      html.push('&lt;/ul&gt;');
      document.getElementById("agenda").innerHTML = html.join("");
    }
  &lt;/script&gt;
  
  &lt;script src="https://gdata.youtube.com/feeds/api/videos?q=all the small things&amp;max-results=2&amp;v=2&amp;format=5&amp;orderby=relevance&amp;safeSearch=none&amp;alt=json-in-script&amp;callback=listEvents"&gt;
  &lt;/script&gt;

  <p>this should return data on the song(query) all the small things. and it does! however what im trying to do with this data is grab the id from the json data, but as i am completely new to json (and js for that matter) i seem to be having a hard time doing this. viewing the page with the network tools i can clearly see the section that contains the id:</p>
  
  <p><code>"id":{"$t":"tag:youtube.com,2008:video:9Ht5RZpzPqw"}</code></p>
  
  <p>and i can clearly see the data that i want(<code>9Ht5RZpzPqw</code>) however no matter how much i scoure json tutorials it makes no sense to me, google seems to do json different than every tutorial ive read. I threw together a jsbin so you can see the results yourself: <a href="http://jsbin.com/atesaf/1" rel="nofollow">jsbin</a>
  Anyone have anyideas? you can see in my code one of the many things i have tried to retrieve that data. Nothing I do seems to work though... Anyone have any ideas or pointers?</p>
