我正在尝试设置scrollspy,但是我无法使效果起作用.我做过研究并经历过 ? 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. 这是我目前的代码. <body data-spy="scroll" data-target="#navtainer" data-offset="0"> 这是视图中的代码 <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>

这是我的Application.js文件. //= require bootstrap //= require jquery //= require jquery_ujs //= require turbolinks //= require_tree . 解决方法
app / assets / javascripts / application.js文件按您指定的顺序加载JavaScript.由于bootstrap使用jQuery,你需要确保jquery和jquery_ujs是第一个被加载的东西.
//= require jquery //= require jquery_ujs //= require bootstrap //= require turbolinks //= require_tree . （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
