詳解Angular4中路由Router類的跳轉navigate,angular4navigate
最近一直在學習angular4,它確實比以前有了很大的變化和改進,好多地方也不是那麼容易就能理解,好在官方的文檔和例子是中文,對英文不太好的還是有很大協助去學習。
官方地址:https://angular.cn/docs/ts/latest/api/router/index/Router-class.html
在學習的過程中路由(router)機制是離不開的,並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 {}
其次路由跳轉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.以根路由跳轉/login
this.router.navigate(['login']);
2.設定relativeTo相對當前路由跳轉,route是ActivatedRoute的執行個體,使用需要匯入ActivatedRoute
this.router.navigate(['login', 1],{relativeTo: route});
3.路由中傳參數 /login?name=1
this.router.navigate(['login', 1],{ queryParams: { name: 1 } });
4.preserveQueryParams預設值為false,設為true,保留之前路由中的查詢參數/login?name=1 to /home?name=1
this.router.navigate(['home'], { preserveQueryParams: true });
5.路由中錨點跳轉 /home#top
this.router.navigate(['home'],{ fragment: 'top' });
6.preserveFragment預設為false,設為true,保留之前路由中的錨點/home#top to /role#top
this.router.navigate(['/role'], { preserveFragment: true });
7.skipLocationChange預設為false,設為true,路由跳轉時瀏覽器中的url會保持不變,但是傳入的參數依然有效
this.router.navigate(['/home'], { skipLocationChange: true });
8.replaceUrl預設為true,設為false,路由不會進行跳轉
this.router.navigate(['/home'], { replaceUrl: true });
