AHAH: Asychronous HTML over HTTP

AHAH is a very simple technique for dynamically updating web pages using JavaScript. It involves using XMLHTTPRequest to retrieve HTML fragments which are then inserted directly into the web page, whence they can be styled using CSS.

Relation to AJAX

AHAH is intended to be a massive simplification of what is commonly called AJAX: "Asynchronous JavaScript and XML."

History

AHAH as a programming technique appears to have been originally invented by Kevin Marks under the name JAH (Just Asynchronous HTML).

Implementations

• There is some talk of directly supporting AHAH in Ruby on Rails using 'partials.'
