Email Protection with MooTools JavaScript v2
Earlier this week I posted an article describing how you can protect your email links from spambots using MooTools. After some suggestions, I've made some improvements to my system.
The XHTML
<span rel="david|davidwalsh.name" class="email custom-class">Email me!</span>
I've switched to using a span tag instead of an anchor to prevent search engines from seeing dead links. We put the modified email address in the rel attribute.
The MooTools JavaScript
window.addEvent('domready', function() {
$$('.email').each(function(el) {
var anchor = new Element('a', {
href: 'mailto:' + el.get('rel').replace('|','@'),
'class': el.get('class'),
'text': el.get('text')
}).replaces(el);
});
});
I create an anchor element and replace the span element that was originally there.
Thank you to everyone that shared their ideas -- we came up with a better script!

CSS filters aren't yet widely supported but they are indeed impressive and a modern need for web imagery. CSS filters allow you to modify the display of images in a variety of ways, one of those ways being displaying images as grayscale.

![Unicode CSS Classes]()
CSS class name structure and consistency is really important; some developers camelcase classnames, others use dashes, and others use underscores. One thing I've learned when toying around by HTML and CSS class names is that you can actually use unicode symbols and icons as classnames.
This version is way cleaner, I assume I can change the pipe to any weirdo special character like �r5981327r0981; then do the replace?
Have you tested how effective is it against spam yet?
If it picks up any spam at all, I guess the next step would be to add in ROT13 to your approach.
Internet explorer 7 doesn’t like the “,” after ‘class’: el.get(‘class’)
That throws an error…
I tried to use this but my Browser does nothing if I click on the E-Mail me text.
@Birke: Works for me.
I had to add ‘text’: el.get(‘text’) to the new anchor element to be able to show the “Email Me” text.
@Wes: Good catch — updated that and compatibility with MooTools 1.3 (removed $each).
Thanks! The only thing i did different was to use title instead of rel. rel isn’t valid in a span.
Greetings,
I am new to mootools and I would like to know were I put the java script code for this?
Thanks for any help.
Perhaps this might help some. For strict xhtml validation if possible use the id attribute and not rel and use a – in replace if |. Making these changes will allow proper validation on strict xhtml.

BTW I figured out were to put the code :)
