With the proliferation of spammers out there, scrapping email addresses off of web sites, this plugin for jQuery makes it easy to hide email address from spam bots.
The plugin is far from perfect, but it works, although I plan to expand on it as time permits. Usage is pretty straight forward, complete documentation is available in the source code for the plugin. The only caveat is that you need an element to append the mailto link to. You can simply place an empty div or span where you want the email link to appear, and access it using the id you have provided. For example:
<p>Here is a bunch of text in a paragraph, where I want an <span id='email_link'></span> to appear. Since the plugin appends to an element, I've included an empty span tag where I want the email address to appear.</p>
