Bootstrap navbar dropdown not working
提问by Cristiano
So I'm trying to get the dropdown in the navbar from Twitter Bootstrap to work, and I'm having some problems.
所以我试图让 Twitter Bootstrap 的导航栏中的下拉菜单正常工作，但我遇到了一些问题。
Here's my html:
这是我的 html：
<ul class="nav">
<li class="active"><%= link_to 'Home', root_path %></li>
<li><a href="#">Forums</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">World</a>
<ul class="dropdown-menu">
<li><%= link_to 'Current', current_path %></li>
<li><%= link_to 'All', all_path %></li>
</ul>
</li>
</ul>
And I also have this in the <head>:
我也有这个<head>：
<script type="text/javascript" src="http://twitter.github.com/bootstrap/assets/js/bootstrap-dropdown.js"></script>
It's just not working, can anyone see anything wrong with it?
它只是不起作用，有人能看出它有什么问题吗？

You are referring to a wrong JS file.
您指的是错误的 JS 文件。
Instead of your <script>tag you use, use the following:
<script>使用以下代码代替您使用的标签：
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css">
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css">
<script src="//netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>
<script src="//netdna.bootstrapcdn.com/bootstrap/3.0.0/js/bootstrap.min.js"></script>
You can read about it here
你可以在这里阅读
At the <ul>class definition, add the relevant navyou wish to use:
在<ul>类定义中，添加nav您希望使用的相关内容：
<ul class="nav nav-tabs">
<ul class="nav nav-tabs">
-----------------------------^^
-----------------------------^^
or
<ul class="nav nav-pills">
或者
<ul class="nav nav-pills">
You can also directly link to bootstrap-dropdown.js through as per your comment, but nevertheless you'd need bootstrap css and js included (I also updated the fiddle):
https://netdna.bootstrapcdn.com/twitter-bootstrap/2.0.4/js/bootstrap-dropdown.js
您也可以根据您的评论直接链接到 bootstrap-dropdown.js，但是您仍然需要包含 bootstrap css 和 js（我还更新了小提琴）：
https://netdna.bootstrapcdn.com/twitter-bootstrap/2.0.4/js/bootstrap-dropdown.js
See fiddle
见小提琴
Also - I see that you use RoR, so make sure it's not a RoR issue on top of the missing JS file.
另外 - 我看到你使用了 RoR，所以请确保它不是丢失的 JS 文件之上的 RoR 问题。

I have the same issue with bootstrap drop-down(in rails). I resolved the issue by removing the //= require_tree .from application.js. And got worked.
我对 bootstrap 下拉（在 Rails 中）有同样的问题。我通过删除//= require_tree解决了这个问题 。来自 application.js。并开始工作。

Update your jquery main file to 1.11.0
and only use bootstrap.min.js bootstrap.min.css and jquery main file
将您的 jquery 主文件更新为 1.11.0 并仅使用 bootstrap.min.js bootstrap.min.css and jquery main file
