ajax - Pure JavaScript code for HTTP Basic Authentication?

Question

Where can I find reference code that implements a HTTP Basic Authentication client in pure JavaScript, suitable for AJAX?

Extra points for code, or pointers to code, that can be used independent of JS toolkits like YUI. No points for Java, Flash/Flex, PHP frameworks, etc.

The five-parameter version of the XMLHttpRequest.open method allows you to specify the username and password. (WHATWG spec)

xhr.open(method, url, async, username, password)
