我无法点击<a routerLink="/login">Login</a>从主页导航到登录页面。我已经阅读了Angular 2网站上的教程和开发者指南。
这就是我在代码中的内容：
的index.html：
<html>
<head>
<base href="/">
<title>Portfolio</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">

<script src="bower_components/bootstrap/dist/js/bootstrap.min.js"></script>
<link href="bower_components/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet">
<link rel="stylesheet" href="css/style.css">

<script src="node_modules/systemjs/dist/system.src.js"></script>
<!-- 2. Configure SystemJS -->
<script src="systemjs.config.js"></script>
<script>
System.import('app').catch(function (err) {
console.error(err);
});
</script>
</head>
<!-- 3. Display the application -->
<body>
<my-app>Loading...</my-app>
</body>
</html>
home.html的：
<nav class="navbar">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">

我做错了什么或者我错过了什么？无论如何，谢谢你的回复。

我找不到Angular 2网站上的任何信息来解决我的问题。所以我看了一个教程，所以归功于教程的这个人的链接：https://www.youtube.com/watch?v=Ppy3ipDzngA
有些代码已被弃用，但它确实解决了我的问题。
以下是我添加的代码：
navbar.component.ts：
import { Component } from '@angular/core';
import {ROUTER_DIRECTIVES} from '@angular/router';
@Component({
moduleId: module.id,
selector: 'navbar',
templateUrl : 'navbar.component.html',
directives: [ROUTER_DIRECTIVES]
})
//AppComponent is the root of the application
export class NavbarComponent {
constructor() {
}
}
navbar.component.html：
<nav class="navbar">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<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" href="#">Portfolio</a>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li class="active"><a a routerLink="/" routerLinkActive="active">Home <span class="sr-only">(current)</span></a></li>
<li><a routerLink="/about" routerLinkActive="active">Over</a></li>
<li><a href="#">Portfolio</a></li>
<li><a href="#">C.V.</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><a routerLink="/login" routerLinkActive="active">login</a></li>
<li><a href="#">Register</a></li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
app.routing.ts：
//import { Routes, RouterModule } from '@angular/router';
import { provideRouter, RouterConfig } from '@angular/router';
import { SearchComponent } from './components/search/search.component';
import { AboutComponent } from './components/about/about.component';
import { LoginComponent } from './components/login/login.component';
//import { LoginComponent } from '../components/login.component';
const appRoutes: RouterConfig = [
{
path: '', //represents the home page
component: SearchComponent,
},
{
path: 'about',
component: AboutComponent,
},
{
path: 'login',
component: LoginComponent,
}
];
export const appRouterProviders = [
provideRouter(appRoutes)
];
main.ts：
//Angular's browser bootstrap function
import { bootstrap } from '@angular/platform-browser-dynamic';
import { appRouterProviders } from './app.routing';
//The application root component, AppComponent
import { AppComponent } from './app.component';
bootstrap(AppComponent, [appRouterProviders]);
app.component.ts：
import { Component } from '@angular/core';
import { NavbarComponent } from './components/navbar/navbar.component';
import {ROUTER_DIRECTIVES} from '@angular/router';
import { SearchComponent } from './components/search/search.component';
import { AboutComponent } from './components/about/about.component';
@Component({
moduleId: module.id,
selector: 'my-app',
templateUrl: 'app.component.html',
directives: [ROUTER_DIRECTIVES, NavbarComponent],
// precompile: [SearchComponent, AboutComponent]
})
//AppComponent is the root of the application
export class AppComponent {
constructor() {
}
}
app.component.html：
<navbar></navbar>
<div class="main">
<div class="container">
<router-outlet></router-outlet>
</div>
</div>
