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幫助去學習。
官方位址:
在學習的過程中路由(router)機制是離不開的,而且好多地方都要用到。
首先路由設定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 {}
其次路由跳轉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 : boolean10 }
1.以根路由跳轉/login
this.router.navigate(['login']);
2.設定relativeTo相對目前路由跳轉,route是ActivatedRoute的實例,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 ,保留先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,保留先前路由中的錨點/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,路由不會進行跳躍
this.router.navigate(['/home'], { replaceUrl: true });
還有好多好多東西要學習,關於跳轉就先寫到這裡了,希望大家共同學習分享踏過的坑。
