Rails：Bootstrap下拉菜单不起作用 [英] Rails: Bootstrap dropdown menu not working
本文介绍了Rails：Bootstrap下拉菜单不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我会说，我最初在我的宝石文件中有bootstrap-sass 2.x，然后更改为3.x，但是返回到2.x，因为我没有意识到去3.x会导致由于类名称更改导致的问题，所以也许这个工作的时候是当我安装了bootstrap-sass 3.x，不确定。我在Windows 8.1中开发，我不得不解决execjs的问题，特别是runtimes.rb文件，所以这里是我的细节：
Gemfile：

真的很感激一些帮助，以解决这个问题。
提前感谢，如果我能提供更多信息，请通知我。
解决方案
是可以确定的问题是我放在assets / javascript目录中的2个胭脂js文件。即bootstrap.js和bootstrap.min.js。一旦我删除了这些文件，下拉菜单再次工作。
I am quite new to Rails and have been following the tutorial by Michael Hartl. Everything has been going along really well until I got to the drop down menu, which was wasn't working, then was working and now isn't working :( I've read several posts and fixes and I suspect my tinkering has gotten to the point where quite simply, I've done something to stop it working. I will say that I initially had the bootstrap-sass 2.x in my gem file, then changed it to 3.x, but went back to 2.x because I didn't realise that going to 3.x would result in issues due to class name changes. So, perhaps the time this was working was when I had bootstrap-sass 3.x installed, not sure. From what I can tell though everything is set up the way it needs to be. I am developing under Windows 8.1 and I had to fix an issue with execjs and in specific the runtimes.rb file. So, here are my details:
Gemfile:
source 'https://rubygems.org'
ruby '1.9.3'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '4.0.2'
gem 'bootstrap-sass', '2.3.2.0'
gem 'sprockets', '2.11.0'
gem 'bcrypt-ruby', '3.1.2'
# Use sqlite3 as the database for Active Record
gem 'mysql2', '0.3.15'
# Use SCSS for stylesheets
gem 'sass-rails', '4.0.1'
# Use Uglifier as compressor for JavaScript assets
gem 'uglifier', '1.3.0'
# Use CoffeeScript for .js.coffee assets and views
gem 'coffee-rails', '4.0.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', platforms: :ruby
# Use jquery as the JavaScript library
gem 'jquery-rails'
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks
gem 'turbolinks'
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder
gem 'jbuilder', '1.2'
application.js
//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require turbolinks
//= require_tree .
_header.html.erb (where the drop down is)
<header class="navbar navbar-fixed-top navbar-inverse">
<div class="navbar-inner">
<div class="container">
<%= link_to "Catered Fit", root_path, id: "logo" %>
<!-- <%= link_to image_tag("logo.jpg", width: "25%"), root_path %> -->
<nav>
<div class="nav pull-right">
<!-- <li><%= link_to "Home", root_path %></li>
<li><%= link_to "Help", help_path %></li> -->
<% if !signed_in? %>
<div class="navbar-form">
<%= form_for(:session, url: sessions_path) do |f| %>
<div class="span2 input-xlarge">
<% f.label :email %>
<%= f.text_field :email, placeholder: "Email" %>
</div>
<div class="span2 input-small">
<% f.label :password %>
<%= f.password_field :password, placeholder: "Password" %>
</div>
<div class="span2">
<%= f.submit "Sign in", class: "btn btn-primary" %>
</div>
<% end %>
<% else %>
<li><%= link_to "Users", '#' %></li>
<li id="fat-menu" class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Account <b class="caret"></b>
</a>
<ul class="dropdown-menu">
<li><%= link_to "Profile", current_user %></li>
<li><%= link_to "Settings", edit_user_path(current_user) %></li>
<li class="divider"></li>
<li>
<%= link_to "Sign out", signout_path, method: "delete" %>
</li>
</ul>
<li><%= link_to "Sign out", signout_path, method: "delete" %></li>
</li>
<% end %>
</div>
</nav>
</div>
</div>
</header>
I don't see any errors in the console window and apart from the drop down everything else is working fine.
The following is the source code from the webpage:

Would really appreciate some help on this to get past this issue.
Thanks in advance, and please let me know if I can provide anymore information.
解决方案
What I was able to determine was the issue was 2 rouge js files that I had placed in the assets/javascript directory. Namely, bootstrap.js and bootstrap.min.js. Once I removed these files the dropdown was working again.
