Javascript and Ruby on rails

I’m learning on creating a website using Ruby on Rails (RoR). I had an
template that I created when I worked with JSP 2 years ago, and now I
to reuse it in my RoR website. This is HTML file

        <li><a href="#">Outdoor</a></li>


<script type="text/javascript" src="js/jquery.Nav.js"></script>

<script type="text/javascript">

and this is the javascript file jquery.Nav.js

(function($) {
 left : currentPageItem.position().left,
// mouse out
reset = setTimeout(function() {
width : currentPageItem.outerWidth(),
left : currentPageItem.position().left
}, options.speed)
}, options.reset);
}); // end each

In the application.html.erb of RoR project, I include the js file like

  <%= javascript_include_tag "jquery.Nav.js" %>

However, my homepage doesn’t work even though I put the inside the body
of RoR project



Is there anyway to embed the $(‘#nav’).spasticNav() into the js file. I
tried many ways but it still doesn’t work. Thanks a lot.

EDIT: I saw some examples online that they embed the function into js
like this.

Are you getting any errors in the javascript console?
