[thelist] Using JavaScript for non-clickable email addresses

I have used this routine in the past.
1) make your anchor a named anchor with no href.
2) break up the email address into parts wrapped in span tags.
3) use an onmouseup event to generate a mailto href. I usually include the
JavaScript function in an external file.
I have tested following is example code in IE and Firefox and used similar
code in Netscape 6+. While I haven't tested it with a text reader, I don't
think it would cause any problems. The email address is legible in
non-JavaScript enabled browsers.

<script type="text/javascript">
function hello(){
 linkArray = "";
 if(arguments[0].nodeName == ("A" || "a")){
  linkArray = "mailto:";
  linkArray = linkArray + arguments[0].firstChild.innerHTML;
  linkArray = linkArray + "@";
  linkArray = linkArray +
  arguments[0].href = linkArray;


<a name="anchor1"
