Only in my spare time, but I want to use it more.

though I'm not using ruby or ror, i did some reading and it looks very
interesting... will you have an install guide for jqor? I have ruby on
my mac, and have run simple programs.... but little more.

Yehuda, I'm looking forward to jQuery on Rails!

</blockquote><div>I think the former (helpers generating jQ code) -- although I'm not sure exactly what the latter would look like.
If you go the helpers route, they should avoid dumping JS inline in the HTML (obviously, this is the beef with the standard Rails JS helpers). It would be nice if the helpers could write all the JS into the header of your document, or into an external JS file.
It looks like the UJS plugin has solved some of these problems already, so it might serve as a useful point of reference. One of the other good things they've done is provided an easy migration path to switch to UJS.

<div>You definitely pay a price in terms of development time. There has been a lot of effort implementing Prototype/scriptaculous support in Rails -- including RJS templates --  and you throw that all away when you go the jQuery route (my applications have been *all* jQ or *all* proto/scriptaculous -- I've never mixed the two)

</blockquote><div>Two Rails apps using exclusively jQ:
- <a href="http://hotspotr.com">hotspotr.com</a> is a map-based app with ratings and reviews. Not huge, but respectable.
- <a href="http://termmap.earthcode.com/build/web20">
http://termmap.earthcode.com/build/web20</a> is smal, but with more JS. It's basically one page, with a lot of JS interaction packed into it.
Thanks for your work on this,
Andre

> 1) Are you using Rails?
Yes, close to 24/7 :-)

And a nice blog post describing on how to create new Rails helpers
(and having a repository for people to post the code to) for easy
integration of the plethora of jQuery plugins would really enrich the
whole concept of jQuery for Rails. After all, jQuery's easy
extensibility should be reflected in the Rails plugin, don't you
think?
Seriously, I just can't wait for the first alpha/beta/release!

</blockquote><div>
I have avoided RoR's automatic javascript stuff, because I read that it's not unobtrusive. But in any case I love to code in jQ (and I agree with Klaus that there are similarities between jQ and Ruby) so have kept it separate from the ruby stuff. I would be interested, though, in helper methods in templates which "hijax" links automatically in an unobtrusive way (including back button issues).

<div>
We have several mini-sites running as separate Rails instances. We have a module with common ruby code in it, but as yet we haven't found a nice way to share javascript resources across projects.

I've carefully read all of the responses to this thread (keep em coming), and believe that my solution will work very well for almost all of the concerns expressed here.
I'll announce more details about the mechanism and syntax sometime in the next week or so, but I believe everyone will be very satisfied.

That's not the main issue, but without MinusMOR, your RJS files would
always look like
page << "some_jquery_code;"
page << "some_jquery_code;"
I don't mind writing JavaScript myself either, but in order for jQuery
for Rails to be easily integrated into existing applications, the
helpers are a must. I have my fair share of applications that combine
both helpers and sporadically some custom JS code, but I don't want to
refactor all my RJS and view code just for being able to integrate
jQuery instead of proto/script. If it could be plug-and-play (and not
plug-and-pray) I wouldn't doubt and just deploy new versions of my
AJAXed apps just for jQuery.

... and a Rails way of keeping the behavior in a separate file
(separate behavior from representation). What I would do now, is
either use a partial to render the JS in the header and put it in my
layout or just add JS files to the public/javascripts directory, but I
don't find it very Rails-like, it doesn't feel like the best solution.

Looks like Luke Redpath's UJS4Rails way of doing things :-) It's not a
bad solution, but UJS4Rails has introduced unreliable behavior in some
of the apps I have been working on.

Here's something similar for PHP I saw on Ajaxian. Apologies if this
has already been noted.
http://www.ngcoders.com/php/pquery-php-and-jquery/
I have not examined it, so I can't say whether it's worth looking at.
