How to: Check if Javascript is enabled

Rails
1

Hi there,

Rails has fantastic Javascript helpers, which I have immediately used
for my website.

Since some features of my website now rely 100% on Javascript being
enabled in the user’s browser, I now need a way to either:
a) block the usage of the site when Javascript is disabled, or
b) display a very visible message that tells the user to enable
Javascript.

Has anybody good ideas for a plugin (or some other solution) to check if
Javascript is enabled and to then let the user know?

(I know, a good programmer would let the site work without JS as well,
but currently, I’m not there yet…)

Thanks a bunch for any help with this!

There is a tag in HTML that does what you want.

Actually, Rails has terrible JS helpers: they encourage a poor style of
programming where JS is mixed into HTML. Generally, this is not a good
idea.

The tag will work, or you could have a message in the HTML
that your JS code will remove.

Not only for this, (because I think that using JavaScript in, almost,
the year 2010 is more than OK), but just because you have to.
