Hi all,

I’d like to write a function that replaces all email addresses in my  
pages with a javascript anti-spam script. I know it’s a bit horrible  
for screen readers, but I feel it’s our best option at the moment.

I think I need some kind of function that builds the javascript  
depending on the email address and then replaces it in the text. I got  
a bit lost at this point!

All of the page content is written in Markdown, fetched from the  
database, and is edited regularly by the site users.

Has anyone done anything like this, or know where I could start?

Thanks a lot,

Tom

I wrote a plugin that automatically adds an enkoded (Hivelogic Enkoder  
is Javascript eval) hidden field to prevent spam. Perhaps not that  
relevant to what you’re trying to do, but thought I’d throw it out  
there.

Actually, it appears that’s a little overkill for what I want. That  
encodes an entire page of content, and I just want to encode the email  
addresses. There must be some kind of regexp I could use?
