Description

When activated, this plug-in scours the document for mailto: email links and obfuscates them using Javascript before sending the result to the browser.

No guarantees as to the spambot-proofness of the actual obfuscation, and please note that it does NOT obfuscate email addresses that are written outside a mailto: link.

Here's a page that uses the obfuscation:

If you want to see what the generated code looks like, do a "View Source."

Instructions

1. Create a new Plugin named whatever you want (i.e. Email Obfuscator). Paste in the code. Save.

2. Under System Events, check the OnWebPagePrerender event.

3. Save and enjoy.
