导航栏折叠在 Bootstrap 中不起作用
[英]Navbar collapse is not working in Bootstrap
问题描述
@Bhanu pratap 解决了这个问题。 在这个问题的末尾检查一下。
我一直在学习建立导航栏折叠（三明治）的旧课程。 问题是课程中的页面似乎在顶部有一个黑条，并且在缩小页面时出现导航栏。 对我来说，我只是在左边得到一个按钮。 另外，当我缩小页面时，我看不到导航栏。
这是源代码：

我试图用另一个源代码更改这部分，但问题又出现了。

更新：@Bhanu pratap 通过添加 ul 和 li 解决了问题以显示可见效果。 这是他的源代码：

<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>

<div class="navbar navbar-inverse navbar-fixed-top" role="navigation">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target=".navbar-collapse">
<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" herf="/"><img src="assets/img/logo.png" alt="Bootstrap to WordPress"></a>

Bootstrap 5 data-* 属性语法已更改，现在您需要在第一个破折号之后添加“bs-”（对于 Bootstrap），然后是 class 规范的 rest。
为您的按钮标签部分试试这个：
<button type="button" class="navbar-toggle collapsed" data-bs-toggle="collapse" data-bs-target=".navbar-collapse"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button>

试试吧..我刚刚在代码中添加了ul和li以显示可见效果，您可以在此处使用代码部分。
<script src="https://code.jquery.com/jquery-2.1.3.min.js"></script> <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script> <link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" rel="stylesheet"/> <div class="navbar-wrapper"> <div class="navbar navbar-inverse navbar-fixed-top" role="navigation"> <div class="container"> <div class="navbar-header"> <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target=".navbar-collapse"> <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" herf="/"><img src="assets/img/logo.png" alt="Bootstrap to WordPress"></a> </div><!-- navbar-header --> <div class="navbar-collapse collapse"> <ul class="nav navbar-nav"> <li> <a href="">First Menu Item</a> </li> <li> <a href="">Second Menu Item</a> </li> <li> <a href="">Third Menu Item</a> </li> </ul> </div><!-- collapse nav--> </div><!-- container --> </div><!-- navbar --> </div>

$(document).on('click','.navbar-collapse.in',function(e) {
if( $(e.target).is('a') && ( $(e.target).attr('class') != 'dropdown-toggle' ) ) {
$(this).collapse('hide');
} });
$("button.navbar-toggle").click(function (e) {
$("#main-navbar").collapse('hide');
$("#main-navbar").removeClass("in"); });

如果您使用的是 Bootstrap 5，对于每个 data-* 属性，请使用 data-bs-* 属性。 例如：
使用<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">它应该可以正常工作。
