I was written an AJAX example on http://www.0011.com/ajax_example and the javascript has the portion like node.innerHTML = "<pre>" + s + "</pre>" and a comment of return false; // don't follow the original link <a href="..." ></a> for some reason, the code won't validate as HTML 4.01... I thought XHTML 1.0 is the one that needs hiding of the Javascript code? HTML 4.01 doesn't need to hide it I thought...? Thanks very much!
