Rails jQuery with Ajax?

I'm a rails newbie and I cant seem to get jquery with ajax to work. I have installed the jquery-rails and done rails g jquery:install. Then I did a sample test by calling an alert in the application.js file and it worked. Then I created a controller action 'index' and made a link to it on one of my other pages. I thought to get ajax to work with it, I would simply create a index.js.erb file. However I the开发者_JAVA技巧n got an error saying template missing, so in my controllers' index action, I put the following code:

respond_to do |format|
 format.html
 format.js
end

However, I am not getting anything displayed on my page. In my index.js.erb file I have a simple alert message to test out if its working, and I cannot get that to even come up. Any suggestions? I don't know if it matters but I am using rails 3.0.7. Thanks in advance

RJS files didn't work with jQuery Plugin, so, you have to use *.js.erb extension in order to use javascript template, and these files are a kind of erb + javascript combination (like *html.erb files).

Just wrote this using rails 3.0.7, jquery plugin should be compatible with rjs syntax

routes.rb

  get "main/index"
  get "main/hello"

main_controller.br

class MainController < ApplicationController
  def index
  end

  def hello
  end

end

hello.js.rjs

page.alert("test");

index.html.erb

<%= link_to 'test', main_hello_path, :remote => true %>
