8. Ajax Inline Edit
AJAX, DOM, whatever you call it makes it possible to let people edit a piece of text inline without having to use a submit button.
The in-place “text edit” testing allows for Flickr-style AJAX-backed “on-the-fly” textfields. The constructor takes three parameters. The first is the element that should support in-place editing. The second is the url to submit the changed value to. The server should respond with the updated value (the server might have post-processed it or validation might have prevented it from changing). The third is a hash of options. The server side component gets the new value as the parameter ‘value’ (POST method), and should send the new value as the body of the response.
An AJAX (or AHAH) proof-of-concept page that allows the visitor to edit the very (x)HTML page they are viewing, without leaving the page. Click the text to be edited and magically a textarea appears with buttons beneath to save or cancel the changes. Changes are sent via AHAH to a PHP script which normally would be used to update a database (MYSQL or flatfile).

Also jTip can be customized by providing user defined widths (defaults to 250px wide) via a url query string.
This module checks your links on the current page by requesting them and reading the server response. If the server returns 200 OK the link gets 'active' class, if other header - the link marked as inactive.
