详解Angular之路由基础

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

const routes: Routes = [];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule]
})
export class AppRoutingModule { }

const routes: Routes = [
  {path: '', component : HomeComponent}, //路径为空
  {path: 'product', component: ProductComponent}
];

<a [routerLink]="['/']">主页</a>

<input type="button" value="商品详情" (click)="toProductDetails()">

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  constructor(private router:Router){
  }
  toProductDetails(){
    this.router.navigate(['/product']);
  }
}

const routes: Routes = [
  { path: '', component: HomeComponent }, //路径为空
  { path: 'product', component: ProductComponent },
  { path: '**', component: Code404Component }
];

const routes: Routes = [
  { path: '', redirectTo : 'home', pathMatch:'full' }, //路径为空
  { path: 'home', component: HomeComponent },
  { path: 'product', component: ProductComponent },
  { path: '**', component: Code404Component }
];
