Rails - Jun 2006 - RJS replaces JavaScript?

Hi All,

I am currently devleoping a Rails application and I need to do following as
part of client side operations,

1. HTML Form validations
2. AJAX

I am currently calling Javascript methods from views of my application; I
heard about RJS(Remote Javascripts) templates; are the replacing Javascript
altogether? can I use RJS for HTML Form validations and AJAX?

What I believe is that with RJS there would be a server round trip as for
every RJS template I have to write a method in controller.
Is there an alternative to Javascript for HTML form validation in rails, or
rather is there any preferred way over Javascript?


Thanks in Advance,
Jatinder

RJS does not replace javascript.  It does however, make updating a page 
with new data as a result of an AJAX request much easier, and make it in 
pure ruby.

For client side form validation pure javascript is really the only way 
to go.

Although client form validation which renders the proper javascript 
autmatically generated form the models validates_* methods sure would be 
a nice plugin.
