title: Iterating through a json array of objects using jquery
body: <p>I know this may seem basic to some of you, but I am trying to iterate a json object. I apologize as I seem to be having difficulty getting various examples to work. I've also read the jQuery documentation and the json examples listed there don't quite match my json structure.</p>
  
  <p>Here's a link to my example which is displaying "null" in the console where I expected to see "1". I'm just trying to print out the article_id element of each "node" in the json array.</p>

  <pre><code>var json = [
      [{
          "article_id": 1,
              "article_title": "test",
              "article_content": "test1"
      }, {
          "article_id": 2,
              "article_title": "test2",
              "article_content": "this is a second test article"
      }]
  ];
  
  $.each(json, function (arrayID, group) {
      console.log(group.article_id);
  });
  </code></pre>
