A really great blog post about how to do javascript includes using "asynchronous javascript" XMLHTTP requests to server-side PHP scripts.

The article shows how to do 'include_once' and 'on-demand' loading of javascript code, which can be executed by the browser to modify the current document, including by use of HTTP GET request results assigned to the DOM.

Wacka-wacka DOOOO!

Today's brain teaser is AJAX + PHP + Javascript + XML + MySQL ... and there may be some others I've left out CSS, XHTML, stuff like that.

Nevertheless, we will prevail. Links to follow.^

• PHP Example - responseXML
• JavaScript and HTML DOM Reference
• XML DOM
• XML Manipulation (from the PHP Manual)

Nothing specific to the MySQL side of this, for now.

The World Wide Web Consortium (W3C) defines the HTML Document Object Module (DOM) as a standard. The DOM is used as a standardized way to programmatically access the content of HTML [and XML – we're only concerned with the HTML, here] documents.

Languages commonly used to access and modify the content of a DOM document instance [an instance of a DOM-conformant document] are Java and Javascript.

In this case, we are interested in accessing and modifying the content (data and meta-data) of an HTML document using Javascript to manipulate HTML elements using DOM-defined methods.
