Dynamic Drive DHTML Scripts- Basic Ajax Routine (get & post)

Dynamic Drive DHTML Scripts- Basic Ajax Routine (get & post): "Description: Regardless of what you do using Ajax, they all rely on the same basic functions. This is a very small Ajax routine (less than 3 Kb) that enables you to easily use Ajax on your site to send 'GET' or 'POST' requests asynchronously. Some examples include getting the contents of an external HTML file, getting the contents of a XML file and return it as a DOM object, and sending information via PoST to a receiving PHP script (with the information being from either a form or any element on the page)."
