我在 Rails 4 中使用 BootStrap Saas gem ( https://github.com/thomas-mcdonald/bootstrap-sass )。 我正在尝试设置 scrollspy，但是我无法使效果正常工作。我做了研究并经历了 Bootstrap 3 scrollspy strange behaviour - not updating active class on scroll , Bootstrap ScrollSpy isn't working , Bootstrap 3 Scrollspy Activate Event Not Firing , 和 Bootstrap scrollspy link active not applied我仍然有问题。
这是我当前的代码。 来自 application.html.erb
<body data-spy="scroll" data-target="#navtainer" data-offset="0">
这是 View 中的代码
<div class="navbar navbar-inverse navbar-fixed-top" id="navtainer">
<div class="container">
<div class="container ">
<div class="navbar-header"> <a class="navbar-brand" href="#">Demo</a></div>
<ul class="nav navbar-nav">
<li class="active"><a href="#intro">Home</a></li>
<li ><a href="#home">home</a></li>
<li><a href="#newest">new</a></li>
<li><a href="#about">about</a></li>
</ul>
</div>
</div>
</div>

这是我的 Application.js 文件。
//= require bootstrap
//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .
最佳答案
app/assets/javascripts/application.js 文件按照您指定的顺序加载 JavaScript。由于 bootstrap 使用 jQuery，因此您需要确保首先加载 jquery 和 jquery_ujs。
//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require turbolinks
//= require_tree .
关于ruby-on-rails - ScrollSpy 未在 bootstrap 3 中激活，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/20380871/
