Bootstrap 导航栏折叠没有折叠

Question

我有一个来自引导程序的导航栏，它没有崩溃。 我将 JQuery 放在引导程序之前，所有 CDNJ 都放在正确的位置，但仍然无法正常工作。

我正在使用引导程序 5

编辑：我解决了这个问题，只是从 bootstrap.bundle.min.js 中删除了完整性并且它有效

Answer 1

使用带有您的 ID 的 Bootstrap 文档中的按钮似乎有效：

    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarCollapse" aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
