18 * <script type="text/javascript" src="javascript/xmlhttprequest.js"></script>
19 * - Add in the page behind the form close tag:
20 * var xmlhttprequest = new Array();
21 * xmlhttprequest[0] = createHTTPHandler(); // AutoDraft handler
22 * xmlhttprequest[1] = createHTTPHandler(); // UpdateTicket handler
23 * var seconds = now(); // Last AutoDraft time
24 * var checks = 0; // Number of checks since last AutoDraft
25 * var addform = document.getElementById('addform'); // The form id
26 * var goal = document.getElementById('lastsaved'); // The html div id where 'Last saved: date time' must come
27 * var goalurl = 'action.php'; // The PHP file where the content must be posted to (action.php)
28 * var lastsavedtext = 'Last saved'; // The language variable for 'Last saved'
29 * var formtype = 'add'; // Add or edit form
30 * - Add to the form tag:
32 * - Add to the textarea's and text fields:
33 * onkeyup="doMonitor();"
34 * - Add tot the selectboxes and radio buttons
35 * onchange="doMonitor();"
37 * <input type="hidden" name="draftid" value="0" />
38 * - Optionally a autosave now button can be add:
39 * <input type="button" name="autosavenow" value="AutoSave now" onclick="autoSaveDraft();" />
43 * Creates the xmlHTTPRequest handler
