title: JQuery parse JSON
body: <p>I'm fairly new to JQuery. The code below works and I can see the correct JSON response in Firebug. But I couldn't find a way how to get and parse it in the code. Alert window only shows
  "[object Object]" but not any json text.</p>
  
  <pre><code>&lt;script&gt;
  
  $.ajaxSetup({ cache: false });
  
  var _token;
  
  function make_token_auth(user, token) {
    var tok = user + ':' + token;
    return "Token " + tok;
  }
  
  
  $.ajax
    ({
      type: "GET",
      url: "url",
      dataType: 'json',    
      beforeSend: function (xhr){ 
          xhr.setRequestHeader('Auth', make_token_auth('userid', 'token')); 
      },
      success: function (data){
          alert(data); 
      }
  });
  
  &lt;/script&gt;
  </code></pre>
