- JavaScript Yourself Anonymous -- In response
to letters on hiding your email address on a Web page to
avoid spammers sucking it down, Joseph McLean
<[email protected]>
wrote us with a nifty JavaScript-based solution, which he
offers for free:
Brandon Munday mentioned how he removed all "clickable"
mailto links from his Web site to thwart the evil
address-collecting spiders. Making a site non-clickable is
so counter to the Web's nature that I became convinced there
had to be another way. And there is - if you turn to
JavaScript for aid.
JavaScript is not ubiquitous technology, but this can
also work in your favor, because spiders don't speak that
language - and most of your human visitors have browsers
that do. Here's an example I cooked up in five minutes.
- <script language=javascript>
- <!--
- // SpamProof Mail Script 1.0 by Joseph
McLean <[email protected]> -
freeware
- // Linktext is the text you want folks to
see and click upon.
- // email1 & email2 are the text on
either side of your email address's @
sign.
-
- var linktext = "Email Me!";
- var email1 = "jsmith";
- var email2 = "where-ever.com";
-
- document.write("<a href=" + "mail" +
"to:" + email1 + "@" + email2 + ">" +
linktext + "</a>")
- //-->
- </script>

This chunk of code can be pasted into your Web page's
HTML at any point. Some old browsers don't support
JavaScript, but they won't hit an error - the mail link will
simply be invisible (as it is to spiders).
