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!
![Create Namespaced Classes with MooTools]()
MooTools has always gotten a bit of grief for not inherently using and standardizing namespaced-based JavaScript classes like the Dojo Toolkit does. Many developers create their classes as globals which is generally frowned up. I mostly disagree with that stance, but each to their own. In any event...
![Create a CSS Cube]()
CSS cubes really showcase what CSS has become over the years, evolving from simple color and dimension directives to a language capable of creating deep, creative visuals. Add animation and you've got something really neat. Unfortunately each CSS cube tutorial I've read is a bit...
![Facebook-Style Modal Box Using MooTools]()
In my oh-so-humble opinion, Facebook's Modal box is the best modal box around. It's lightweight, subtle, and very stylish. I've taken Facebook's imagery and CSS and combined it with MooTools' awesome functionality to duplicate the effect.
The Imagery
Facebook uses a funky sprite for their modal...
![PHP IMDB Scraper]()
It's been quite a while since I've written a PHP grabber and the itch finally got to me. This time the victim is the International Movie Database, otherwise known as IMDB. IMDB has info on every movie ever made (or so it seems). Their...
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 :)
