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:

 1 import { NgModule }             from '@angular/core';
 2 import { RouterModule, Routes } from '@angular/router';
 3  
 4 import { HomeComponent }   from './home.component';
 5 import { LoginComponent }      from './login.component';
 6 import { RegisterComponent }  from './register.component';
 7  
 8  const routes: Routes = [
 9    { path: '', redirectTo: '/home', pathMatch: 'full' },
10    { path: 'home',  component: HomeComponent },
11    { path: 'login', component: LoginComponent },
12    { path: 'heroes',     component: RegisterComponent }
13  ];
14  
15  @NgModule({
16    imports: [ RouterModule.forRoot(routes) ],
17    exports: [ RouterModule ]
18  })
19  export class AppRoutingModule {}
View Code

其次路由跳转Router.navigate

1 navigate(commands: any[], extras?: NavigationExtras) : Promise<boolean>
 1 interface NavigationExtras {
 2     relativeTo : ActivatedRoute
 3     queryParams : Params
 4     fragment : string
 5     preserveQueryParams : boolean
 6     queryParamsHandling : QueryParamsHandling
 7     preserveFragment : boolean
 8     skipLocationChange : boolean
 9     replaceUrl : boolean
10 }
View Code

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 }); 

 

还有好多好多东西需要学习,关于跳转就先写到这里了,希望大家共同学习分享踏过的坑。
