- * xmlhttprequest[0] = createHTTPHandler(); // AutoDraft handler
- * xmlhttprequest[1] = createHTTPHandler(); // UpdateTicket handler
- * var seconds = now(); // Last AutoDraft time
- * var checks = 0; // Number of checks since last AutoDraft
- * var addform = document.getElementById('addform'); // The form id
- * var goal = document.getElementById('lastsaved'); // The html div id where 'Last saved: date time' must come
- * var goalurl = 'action.php'; // The PHP file where the content must be posted to (action.php)
- * var lastsavedtext = 'Last saved'; // The language variable for 'Last saved'

- * - Add to the form:
