How do I install bootstrap js?
<p>I followed the hartl rails book to install the bootstrap css files, but I believe I'm missing the javascript to go with it. Here's what the book told me to do:  </p>

<ol>
<li>add <code>bootstrap-sass</code> to the Gemfile: <code>gem 'bootstrap-sass'</code></li>
<li>run bundle install  </li>
<li><p>add the following to the css:</p>

<pre><code>@import "bootstrap-sprockets";
@import "bootstrap";
</code></pre></li>
</ol>

<p>What else do I need to do to add the javascript portion? my <code>application.js</code> right now:</p>

<pre><code>//= require jquery
//= require bootstrap
//= require jquery_ujs
//= require turbolinks
//= require_tree .
</code></pre>
