Question

如何在单击滚动间谍链接时折叠 Bootstrap 汉堡的菜单？

在智能手机上查看我的网站时，引导程序导航被简化为汉堡菜单。如果您单击指向我的 index.html 中特定位置（例如 #aboutMe）而不是外部页面的链接，则导航将保持展开状态。我希望它之后再次崩溃。

您可以查看代码：https://github.com/senkvalentin/personal_page 或访问网站：https://senkvalentin.com/

这是我的 html 的一部分：

我已经看过了：How to hide collapsible Bootstrap navbar on click
并且：Bootstrap panel-collapse collapses when you click on a link inside it is clicked

但没有任何效果。

我使用的是最新版本的 jQuery 和 Bootstrap 5.0.1 版：

<script src="https://code.jquery.com/jquery-latest.js"></script>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.1/dist/js/bootstrap.bundle.min.js" integrity="sha384-gtEjrD/SeCtmISkJkNUaaKMoLD0//ElJ19smozuHV6z3Iehds+3Ulb9Bn9Plx0x4" crossorigin="anonymous"></script>

Answer 1

在 Jquery 中，当点击链接时，只需在 navbar-toggler 按钮上触发点击

$('.nav-link').click(function(){
  $('.navbar-toggler').click();
});

$('.nav-link').click(function(){
  $('.navbar-toggler').click();
});

  height:100vh;

Answer 2

您首先需要选择除 .nav-link 之外的所有 .dropdown-toggle。
然后，分配一个事件侦听器以在点击时切换 .navbar-collapse：

$(document).ready(() => {
  let $navlinks = $('.nav-link').not('.dropdown-toggle');
  // console.log($navlinks)
  $navlinks.click((e) => {
    $(e.target).closest('.navbar').find('.navbar-collapse').collapse('toggle')
  })
})
