title: ajax call return list
body: <p>I am making an ajax call</p>
  
  <pre><code>     $.ajax({
             url: urpath,
             type: 'POST',
             dataType: 'json',
             data: JSON.stringify(json),
             contentType: 'application/json; charset=utf-8',
             success: function (data) {
                          alert(data);
                      },
             error: error
       });
  </code></pre>
  
  <p>The returning data is a list which has 2 columns. How do I iterate through the list and show the data. When I do alert(data) it just says object object? </p>
