  <p>My Json response looks like this:</p>
  
  <pre><code>[{"referenceid":"999","firstname":"Firstname","middlename":"Middlename","lastname":"Surname","shortlisted":"0"}]
  </code></pre>
  
  <p>How can I just retrieve the referenceid value? I've searched and searched... tried all sorts of things but I can only return a "undefined".</p>
  
  <p>Thanks</p>
  
  <p>edit:</p>
  
  <p>Forgot my other code:-</p>
  
  <pre><code>function populateFormData() {
  
  var mxKey = $.now();
  
  $.get("\\web\\php\\somesite\\phpData.php?mxKey" + mxKey, function(applicationData) {
  
      console.log("Application Data: " + applicationData);
  
      var jsonData = JSON.parse(applicationData);
  
      console.log("Json Parse Data: " + jsonData);
  
  });
  </code></pre>
  
  <p>}</p>
