我正在尝试在我的 Rails 应用程序中实现下拉菜单。我已经复制了正确的代码来显示下拉菜单,但是当我尝试单击菜单时它没有显示正确的选项。

使用 bootstrap cdn:

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Idealprospects</title>
<%= stylesheet_link_tag "application", media: "all", "data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
<%= csrf_meta_tags %>
</head>
<body>

index.html.erb

<div class="container">
<h1>Your Prospects</h1>
<table class="table table-striped table-bordered">
<tr>
<th class="center">Company</th>
<th class="center">Name</th>
<th class="center">Email</th>
<th class="center">Telephone</th>
<th class="center">Website</th>
<th class="center">Action</th>
</tr>

<% @posts.each do |post| %>
<tr>
<td><%= post.company %></td>
<td><%= post.contact %></td>
<td><%= post.email %></td>
<td><%= post.telephone %></td>
<td><%= post.website %></td>
<td>
<div class="btn-group">
<button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown">
Action <span class="caret"></span>
</button>

<ul class="dropdown-menu" role="menu">
<li><%= link_to 'Show', post, class: "btn btn-link" %></li>
<li><%= link_to 'Edit', edit_post_path(post), class: "btn btn-link" %>
<li><%= link_to 'Destroy', post, method: :delete, data: { confirm: 'Are you sure?' }, class: "btn btn-link" %> </li>
</ul>
</div>
</td>
</tr>
<% end %>
</table>

<br>

<%= link_to 'New Post', new_post_path, class: "btn btn-link" %>

</div>

最佳答案

从你的代码中我看到你只包含了 bootstrap.css 而它也需要 js

http://getbootstrap.com/components/#dropdowns

下拉菜单

Toggleable, contextual menu for displaying lists of links. Made interactive with the dropdown JavaScript plugin.
