I’ve developed a system in my application where emails are picked up with a regex, and then reversed in the source (to thwart bots). I then add the span class ‘obfuscate email’. I then use CSS to reverse the the text back to be displayed and Javascript make sure that mailto: links still work.

I was pretty happy with my solution until I realised that copying and pasting the email puts it in the clipboard backwards. I was wondering if there was any way I could remedy this? I’ve been testing in Firefox 3 for OS X.

The page in question is available here: http://www.leaklocations.com.au/contact-us/

To see the problem, simply copy and paste the email on that site.

  1. I personally think it’s going a bit over the top, but if you really want to obfuscate the address, why not obfuscate it in a human readable way? Instead of reversing the address, make the server output ‘info at leaklocations dot com dot au’ and get javascript to fix it up?

    If you wanted to stick to using the RTL CSS method, you could try playing around with the unicode character to reverse text: \u202E I’m not sure if that will help, but it’s worth looking at

    To see how this works, run this javascript:

    alert('one \u202E two \u202E three')

    and it’ll output ‘one owt three’
