Angular 有角度的页面可以'；t打开

我是

Angular

的初学者，我正在尝试制作示例网站，我有一些问题，我有两个页面，about.component.html和Contact.component.html

但我无法打开那些页面

我想知道如何正确设置链接，以及最好的方法是什么 用于开发网站

Angular

或

Angular js

应用程序导航栏.component.html

   <nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top">
      <a class="navbar-brand" href="#">Navbar</a>
      <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault" aria-expanded="false" aria-label="Toggle navigation"     (click)="toggleCollapsed()">

您应该使用

routerLink

。不

href

您可以

routerLink

。导入

路由模块后

如果您想路由到

关于组件

，您应该在

app routing.module.ts

中为

关于组件

编写

路由信息

这里有官方文件=>>

示例代码为（仅限必需代码）

您应该使用路由链接

---

并确保您在路由

{path:'about.component'，component:AboutComponent}，

中添加了该组件。您应该使用路由链接

---

并确保您在Routes

{path:'about.component'，component:AboutComponent}，

中添加了该组件，请使用[routerLink]=“['/about']”或[routerLink=“/about”或[routerLink]=“[/someexpressionvariable]”加里Sir感谢您的指导使用[routerLink]=“['/about']”或[routerLink]=“[/someexpressionvariable]”“]“@Gary先生感谢指南先生感谢您的回答和指南，它为meSir所做的工作感谢您的回答和指南，它为meSir所做的工作感谢您的回答和指南先生感谢您的回答和指南
