angular 路由

<router-outlet></router-outlet>
根目录下面创建 app-routing-module.ts
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

const routes: Routes = [
{path: '', redirectTo: '/home', pathMatch: 'full'},
{path: '**', redirectTo: 'home'}
]

@NgModule({
imports: [ RouterModule.forRoot(routes) ],
exports: [ RouterModule ]
})
export class AppRoutingModule { }

app.module.ts
import { AppRoutingModule } from './app-routing-module';

imports: [
AppRoutingModule
],

<a routerLink="/home" routerLinkActive="w100">333</a>

跳转的时候传值

<a [routerLink] = "['/news']" [queryParams]="{ddd: 'news'}">新微页面</a>

获取路由的传值
import { ActivatedRoute } from '@angular/router'

组件里面获取
import { ActivatedRoute } from '@angular/router';
constructor(
public route: ActivatedRoute
) { }
this.route.queryParams.value.ddd
this.route.queryParams.subscribe((data) => {
console.log(data);
})

传动态路由的值
<a routerLink = "/news/{{4}}" [queryParams]="{ddd: 'news'}">新微页面</a>
<a [routerLink] = "['/news/', 4]" [queryParams]="{ddd: 'news'}">新微页面</a>
获取动态路由的值
this.route.params.subscribe((data) => {
console.log(data);
});

js动态路由
import { Router } from '@angular/router';
constructor(
public router: Router
) { }
this.router.navigate(['/news', 3]);

this.router.navigate(['/login'], {
queryParams: {
addd: '111'
}
});
或者
import { NavController } from '@ionic/angular';
constructor(
public nav: NavController
) { }
goBack () {
this.nav.navigateBack('/tabs/' + this.baclUrl);
this.nav.navigateForward('/serach');
}

组件里面获取动态路由
import { ActivatedRoute } from '@angular/router';
this.route.params.subscribe((data) => {
console.log(data);
});

懒加载
{ path: 'news', loadChildren: './components/news/news.component#模块名字expoer class 名字'},

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 });
