導航欄在引導程序 3.3.7 中不會折疊
[英]Navbar is not collapsing in bootstrap 3.3.7
問題描述
我正在使用 bootstrap 3.3.7 並且我的導航欄沒有在較小的設備上折疊。 navbar-toggle確實出現，但單擊navbar-toggle按鈕不會顯示任何選項。
<nav class="navbar navbar-inverse navbar-fixed-top"> <div class="container"> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-nav-demo" aria-expanded="false"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a href="index.html" class="navbar-brand"> <div class="orange"><i class="fas fa-football-ball"></i> Fantasy</div> </a> </div> <div class="collapse navbar-collapse" id="bs-nav-demo"> <ul class="nav navbar-nav"> <li><a class="active" href="index.html">Home</a></li> <li><a href="history.html">History</a></li> <li><a href="picks.html">Picks & Busts of the Week</a></li> <li><a href="news.html">Important Dates/Announcements</a></li> <li><a href="blog.html">Chat/Blog</a></li> </ul> </div> </div> </nav>

如果您正在使用 boostrap，請嘗試此操作
<nav class="navbar navbar-expand-md bg-dark navbar-dark">
<a class="navbar-brand" href="#">Navbar</a>
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsibleNavbar">
<span class="navbar-toggler-icon"></span>
</button>
<div class="collapse navbar-collapse" id="collapsibleNavbar">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link</a>
</li>
</ul>
</div>
</nav>

它確實出現了，但點擊它並沒有出現任何選項
問題可能主要是由於您沒有正確加載所需的 JavaScript 文件。 您可以通過文檔獲取 CDN。 不要忘記添加 Jquery CDN，因為您使用的是 3.3.7 版並且文檔中沒有正確提及。 . 將這些script標簽添加到您的 HTML

這是一個工作示例。

我有同樣的問題。 我的按鈕沒有以移動尺寸展開菜單。 我在本教程中使用了相同的腳本：
但什么都沒有改變。
這是我的菜單的唯一鏈接：
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
這是我的 Bootstrap 菜單的完整代碼：
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<meta charset="utf-8">
<title>Daily Journal</title>
<meta charset="utf-8">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<link rel="stylesheet" href="/css/styles.css">
</head>
<body>
<nav class="navbar navbar-default">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" aria-expanded="false" data-toggle="collapse" data-target="#myNavbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="/">DAILY JOURNAL</a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav navbar-right">
<!-- 6 NAVIGATIONS -->
<li class="active" id="home"><a href="/">HOME</a></li>
<li id="about"><a href="/about">ABOUT US</a></li>
<li id="contact"><a href="/contact">CONTACT US</a></li>
</ul>
</div>
</div>
</nav>
</body>
