It’s a snippet which allows email addresses to be cloaked or hidden from SPAM bots. Of course, this method is not foolproof, in fact:You sit Joe Cracker down with the code for an hour or so and he’ll correct his RegEx-capable parsing spider to decode even this.

Nice snippet.
You might want to make use of the $modx->regClientStartup() function so you can register the javascript function inside the head tag
I know Aour had another solution, I’ll notify him maybe he can add to this very useful feature !
Thanks

Hello fellow MODx-ers. I’ve been using MODx for a while now and have finally got something to contribute. I must admit, this is the first time I’ve ever contributed to an Open Source project, so please be gentle.
You sit Joe Cracker down with the code for an hour or so and he’ll correct his RegEx-capable parsing spider to decode even this.
I cannot see any other alternatives to this yet, and the code is very raw. If anyone can think of any improvements, I’m all open to suggestions. One feature I quite like is that you can set a page ID using $spage to make the link direct to a contact form in case Javascript is disabled.
Anyways, here is the code. This is still a work in progress though. Remember, be gentle...
{EDITED: To include the <script> block of Javascript using $modx->regClientStartup() - Thanks Raymond!}

is the email cloak snippet more secure than this one ?
