Simple spam protection for email addresses using jQuery

/* 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.
 * <a href="mailto:foo(at)example(dot)com">foo at example dot com</a>
 * →
 * <a href="mailto:foo@example.com">foo@example.com</a>
 */

$(function() {
 $('a[href^="mailto:"]').each(function() {
  this.href = this.href.replace('(at)', '@').replace(/\(dot\)/g, '.');
  // Remove this line if you don't want to set the email address as link text:
  this.innerHTML = this.href.replace('mailto:', '');
 });
});

Thanks for this.. I wanted to obscure it from scrapers a bit further as most of them are looking for mailto::

<a href="javascript:" data-email="sales[at]alto[dot]com[dot]au"></a>

$('a[data-email]').each(function () {
      this.href = 'mailto:' + $(this).attr('data-email').replace('[at]', '@').replace(/\[dot]/g, '.');
      this.innerHTML = this.href.replace('mailto:', '');
});
