Item8477: Strikeone should warn users if they have have js turned off

I installed noscript on my netbook, and suddenly, I was losing every edit I made on foswiki.org and trunk.foswiki.org

1. edit topic (you get raw edit)
2. hit save
3. see 'Warning! Confirmation required' dialog
4. hit 'OK', as it says '# Press OK to confirm that this change was intentional.'
5. goes to view topic and no save has occurred.

I'm not thrilled that our protection breaks legitimate usage with js off

but a much bigger issue is that there is nothing telling the innocent user that they are about to lose their work, or why.

This is a very real issue, but I'm somewhat at a loss to know what to do about it. Suggestions are welcome, code even more welcome.

Since strikeone may not be enabled .

Best would be to disable edit when JS is not enabled AND strikeone is enabled. This means telling the JS if strikeone is enabled. I am no JS expert but I assume it is possible but a bit messy.

I personally consider this less urgent. I think very few users run with JS off these days because nothing on the internet works without anymore.

How does the server know JS is disabled? How does it know it has been disabled by the user, rather than it's been disabled because someone is trying a cross-posting hack? There is no automatic, safe solution to this without fatally weakening the protection that strikeone offers. The only option is to add a message to the confirmation dialog that says something like:

"If JS is off, then go back in the browser and turn it on before trying to save again" if strikeone is enabled.

After some experimentation, I can make the message rewrite using onload JS. Not sure how reliable it will be, but worth a try.
