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!
![fetch API]()
One of the worst kept secrets about AJAX on the web is that the underlying API for it, XMLHttpRequest, wasn't really made for what we've been using it for. We've done well to create elegant APIs around XHR but we know we can do better. Our effort to...
![How to Create a Twitter Card]()
One of my favorite social APIs was the Open Graph API adopted by Facebook. Adding just a few META tags to each page allowed links to my article to be styled and presented the way I wanted them to, giving me a bit of control...
![Style Textarea Resizers]()
Modern browsers are nice in that they allow you to style some odd properties. Heck, one of the most popular posts on this blog is HTML5 Placeholder Styling with CSS, a tiny but useful task. Did you know you can also restyle the textarea resizer in WebKit...
![Record Text Selections Using MooTools or jQuery AJAX]()
One technique I'm seeing more and more these days (CNNSI.com, for example) is AJAX recording of selected text. It makes sense -- if you detect users selecting the terms over and over again, you can probably assume your visitors are searching that term on Google...
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 :)
