最近一直在学习angular4，它确实比以前有了很大的变化和改进，好多地方也不是那么容易就能理解，好在官方的文档和例子是中文，对英文不太好的还是有很大帮助去学习。
官方地址：https://angular.cn/docs/ts/latest/api/router/index/Router-class.html
在学习的过程中路由（router）机制是离不开的，并且好多地方都要用到。
首先路由配置Route：
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { HomeComponent } from './home.component';
import { LoginComponent } from './login.component';
import { RegisterComponent } from './register.component';
const routes: Routes = [
{ path: '', redirectTo: '/home', pathMatch: 'full' },
{ path: 'home', component: HomeComponent },
{ path: 'login', component: LoginComponent },
{ path: 'heroes', component: RegisterComponent }
];
@NgModule({
imports: [ RouterModule.forRoot(routes) ],
exports: [ RouterModule ]
})
export class AppRoutingModule {}
其次路由跳转Router.navigate
navigate(commands: any[], extras?: NavigationExtras) : Promise<boolean>
interface NavigationExtras {
relativeTo : ActivatedRoute
queryParams : Params
fragment : string
preserveQueryParams : boolean
queryParamsHandling : QueryParamsHandling
preserveFragment : boolean
skipLocationChange : boolean
replaceUrl : boolean
}
1.以根路由跳转/login
this.router.navigate(['login']);
2.设置relativeTo相对当前路由跳转，route是ActivatedRoute的实例，使用需要导入ActivatedRoute
this.router.navigate(['login', 1],{relativeTo: route});
3.路由中传参数 /login?name=1
this.router.navigate(['login', 1],{ queryParams: { name: 1 } });
4.preserveQueryParams默认值为false，设为true，保留之前路由中的查询参数/login?name=1 to /home?name=1
this.router.navigate(['home'], { preserveQueryParams: true });
5.路由中锚点跳转 /home#top
this.router.navigate(['home'],{ fragment: 'top' });
6.preserveFragment默认为false，设为true，保留之前路由中的锚点/home#top to /role#top
this.router.navigate(['/role'], { preserveFragment: true });
7.skipLocationChange默认为false，设为true，路由跳转时浏览器中的url会保持不变，但是传入的参数依然有效
this.router.navigate(['/home'], { skipLocationChange: true });
8.replaceUrl默认为true，设为false，路由不会进行跳转
this.router.navigate(['/home'], { replaceUrl: true });
