ObfJS - a different approach to obfuscating email addresses

How it works

This jQuery plugin updates the email addresses on the page by only placing the email address in the <a> when the user hovers over the link. This way a bot or scraper would have to actively hover over your link in order to get at your email address.

Usage

The plugin can be included after the initialisation of jQuery (I'm working on a vanilla version). The markup adds two data- attributes (data-begin & data-end) but I'm open to recommendations on whether this is the best way or whether to split a rel attribute instead. See markup below for example codes.

HTML

<a href="#" data-begin="hello" data-end="ianculshaw.co.uk">Email me!</a>
<!-- or -->
<a class="email" href="#" data-begin="hello" data-end="ianculshaw.co.uk">Email me!</a>

Javascript

$('a').ObfJS();
// or
$('.email').ObfJS();

Roadmap

This isn't the best all round solution as it will fail miserably on mobile. I'm thinking about how to tackle this, all ideas are welcome.

Help!

By all means fork this and improve it, together we can unite and rise up against the machines.
