jquery.email-antispam.js

/* Simple spam protection for email addresses using jQuery.
 * Well, the protection isn’t jQuery-based, but you get the idea.
 * This snippet allows you to slightly ‘obfuscate’ email addresses to make it harder for spambots to harvest them, while still offering a readable address to your visitors.
 * E.g. Changed "at" to "atty" and "dot" to "dotty" to confuse some of the more intelligent harvesters.
 * <a href="mailto:foo(atty)example(dotty)co(dotty)uk">foo aty example dotty co dotty uk</a>
 * →
 * <a href="mailto:foo@example.com">foo@example.co.uk</a>

  // Remove this line if you don't want to set the email address as link text:
  this.innerHTML = this.href.replace('mailto:', '');
