我正在尝试实现工具提示功能,如下所示:http: //twitter.github.com/bootstrap/javascript.html#tooltips使用 Ruby on Rails 3 的 Bootstrap-sass gem。我已经完成了以下操作,但它没有'不起作用(当我将鼠标悬停在文本上时,文本不会出现):
在宝石文件中:
gem 'bootstrap-sass', '2.1'
在 application.js 中:
//= require bootstrap
在 show.js.erb 中:
$('#example').tooltip(options);
在 show.html.erb 中:
<a href="#" id="example" title="first tooltip" data-placement="right">
hover over me</a>
为什么这不起作用?
应用程序.js:
//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require_tree .
视图/布局/application.html.erb:
<!DOCTYPE html>
<html>
<head>
<title><%= full_title(yield(:title)) %></title>
<%= stylesheet_link_tag "application", media: "all" %>
<%= javascript_include_tag "application" %>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js?ver=1.4.0"></script>
<%= csrf_meta_tags %>
<%= render 'layouts/shim' %>
</head>
<body>
<%= render 'layouts/header' %>
<div class="container">
<%= yield %>
<%= render 'layouts/footer' %>
<%= debug(params) if Rails.env.development? %>
</div>
</body>
</html>
