Angular 13 和 Bootstrap 5 | UI 添加路由时消失

Question

我一直在开发一个网站，但一直无法超越导航。我遇到的问题是，当我设置路线时，整个 UI 消失并且不会加载。我无法找到任何关于此的信息或它可能发生的原因，但将不胜感激任何形式的帮助或指导！

navi.component.html

<nav class="navbar navbar-expand-md navbar-light bg-light bg-gradient shadow rounded">
    <div class="container-xxl ">
        <a href="#home" class="navbar-brand">
            <span class="fw-bold">
                207 Tech Services
            </span>
        </a>
        <!-- Toggle button mobile nav -->
        <button class="navbar-toggler text-light" type="button" data-bs-toggle="collapse" 
        data-bs-target="#main-nav" aria-controls="main-nav" aria-expanded="false" 
        aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
        </button>

        <div class="collapse navbar-collapse justify-content-end align-center" id="main-nav">
            <ul class="navbar-nav fw-light">
                <li class="nav-item">

Answer 1

在你的app-routes.module.ts中，你不应该在路由路径定义上使用/；即，使用 home 而不是 /home.

在您的 navi.component.html 中，Angular 中的 href 指令刷新了页面。请在 nav 栏的 a 标签中用 routerLink 指令更新所有 href 指令。
