// | What is this nonsense?? (07/09/04) |
// +----------------------------------------------------------------------+
// | This is a script that, by using XMLHttpRequest javascript objects |
// | you can quickly add some very click live interactive feed back to |
// | your pages that reuire server side interaction. |
// | |
// | For instance, you use this to emulate a "live searching" feature |
// | wherein users type in key phrases, and once they have stopped typing |
// | the script will automatically search and retrive *without* a page |
// | reload.
// | |
// | In another instance, I use this to product live comments by passing |
// | the text to a Textile class that parses it to valid HTML. After |
// | parsing, the html is returned and displayed on the page as the |
// | user types. |

// | Hacked apart Jeff's script for use in Mantis. |
// | |
// | This script gets filters from the server and displays them without |
// | reloading the page. |
// | |
// | The script tries to follow the notion of "unobtrusive javascript". |
// | There are no event handlers in the HTML code. The events are added |
// | on pageload(based on specific id names). |
