角度路由问题-更新url但不更新页面

我有两个部分,家和欢迎。欢迎有一个按钮,点击时,应该把我带到'主页'。相反,它会将url更新为“ http://localhost:4200/home “什么也不做。按钮保留,而不是替换为“主零部件”内容。

应用模块ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { RouterModule, Routes } from '@angular/router';

import { AppComponent } from './app.component';
import { WelcomeComponent } from './pages/welcome/welcome.component';
import { HomeComponent } from './pages/home/home.component';

const appRoutes: Routes = [
  { path: 'welcome', component: WelcomeComponent },
  { path: 'home', component: HomeComponent }
];

@NgModule({
  declarations: [
    AppComponent,
    WelcomeComponent,
    HomeComponent
  ],
  imports: [
    BrowserModule,
    RouterModule.forRoot(
      appRoutes
    )
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

欢迎.ts

import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router';

@Component({
  selector: 'app-welcome',
  templateUrl: './welcome.component.html',
  styleUrls: ['./welcome.component.css']
})
export class WelcomeComponent implements OnInit {

  constructor(private router: Router) { }

  ngOnInit() {
  }

  myFunction() {
    this.router.navigate(['/home'])
  }

}

<button class="btn btn-success" type="button" id="loginButton" (click)="myFunction()">Sign In</button>

<p>
  home works!
</p>
