最近一直在學(xué)習(xí)angular4,它確實比以前有了很大的變化和改進(jìn),好多地方也不是那么容易就能理解,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(xué)習(xí)。
官方地址:https://angular.cn/docs/ts/latest/api/router/index/Router-class.html
在學(xué)習(xí)的過程中路由(router)機制是離不開的,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 {}其次路由跳轉(zhuǎn)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(zhuǎn)/login
this.router.navigate(['login']);
2.設(shè)置relativeTo相對當(dāng)前路由跳轉(zhuǎn),route是ActivatedRoute的實例,使用需要導(dǎo)入ActivatedRoute
this.router.navigate(['login', 1],{relativeTo: route}); 3.路由中傳參數(shù) /login?name=1
this.router.navigate(['login', 1],{ queryParams: { name: 1 } }); 4.preserveQueryParams默認(rèn)值為false,設(shè)為true,保留之前路由中的查詢參數(shù)/login?name=1 to /home?name=1
this.router.navigate(['home'], { preserveQueryParams: true }); 5.路由中錨點跳轉(zhuǎn) /home#top
this.router.navigate(['home'],{ fragment: 'top' });6.preserveFragment默認(rèn)為false,設(shè)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默認(rèn)為false,設(shè)為true,路由跳轉(zhuǎn)時瀏覽器中的url會保持不變,但是傳入的參數(shù)依然有效
this.router.navigate(['/home'], { skipLocationChange: true });8.replaceUrl默認(rèn)為true,設(shè)為false,路由不會進(jìn)行跳轉(zhuǎn)
this.router.navigate(['/home'], { replaceUrl: true }); 以上就是本文的全部內(nèi)容,希望對大家的學(xué)習(xí)有所幫助,也希望大家多多支持錯新站長站。
