W3C-Compliant Anti-Spam E-mail Links

Hi All,

I have created a website for a philanthropic organisation I am a member of (www.brightonpgl.co.uk). I do not want the e-mail addresses to get harvested by spambots, so I use a simple bit of JavaScript to generate the addresses.

Code:

  <script language="javascript" type="text/javascript">
   var user = "bro.dhobbs";
   var domain = "gmail";
   var suffix = "com";
   var display = "Contact the webmaster";
   document.write('<a href="' + 'mailto:' + user + '@' + domain + '.' + suffix + '">' + display + '</a>');
  </script>

Unfortunately, this means the page will not validate with the W3C (see http://validator.w3.org/check?uri=www.brightonpgl.co.uk), giving the error "document type does not allow element 'a' here".

I have tried a number of different solutions (moving the Javascript to a function in the HEAD section, trying different combinations of text and variables, etc), but nothing validates. Any ideas how I get around this, while still preventing the spambots from grabbing the addresses?

Thanks

Daniel

Steven,

Thanks for that. I have now extracted the JavaScript into a seperate file (something I should have done anyway, but I was being lazy!). Now both XHTML and CSS valid!
