Ruby on rails3 where to put javascript code

I'm pretty much a novice to the world of Ruby on Rails, a few weeks back I followed Lynda's good ruby on rails guide so I kinda know how to set up a project etc. Anyway, I made an website in html/css but wanted to do it in rails after all so I went to work. I love ho开发者_StackOverflow社区w you can just "dump" files in folders and rails just picks them out but I also had a few lines of javascript code on my site to "activate" the jquery following. It was in my header

<script type="text/javascript" id="sourcecode">
    $(function(){

    $('.scroll-pane').jScrollPane({
    showArrows: false,
    autoReinitialise: true
        });

});
</script>

So the simple question now is, where do I put this code since rails doesn't really have an .

Check out this page for layout and rendering: http://guides.rubyonrails.org/layouts_and_rendering.html

There is a section there about rendering your ERB templates. You need to put your javascript code in your .erb template, within the head, just like you would in a normal HTML page.

To be clear, you can save the contents of your script tag into a .js file and link to it in your template, just like you would in plain HTML.

You can place your JS:

• in the erb template it deals with
• under public/javscripts in a normal .js file that you can include in templates using the javascript_include_tag helper
• in seperate .js.erb template files for ajaxian / manual include purposes

EDITED, per suggestion:

Personally, I'd choose one of the last 2 since those are more Convention over Configuration, or the "Rails" way, which is what I believe you're looking for.

I put all scripts in public/javascripts in a directory structure that mirrors controller/action names + a vendor directory and a common directory. In my application.html.* I have code to load what I need for the controller/action into the header. I make a strong effort to not put javascript into my .haml (.erb) files but am willing to break that rule if I must.

I would put them in public/javascripts/ until Rails 3.1.

Also make sure you are including your javascripts in the template.

<% javascript_include_tag :all %>

For loading reasons, don't you want certain javascript snippets to be called after the template loads rather than in the beginning (ex: called in the header)?
