标签routerLink路由传递参数
url中get传值
// queryParams 传递的是一个对象
<a [routerLink]="[ '/endpage/']" [queryParams]="{name:'huangbiao',age:30}">endpage</a>
定义路由
const routes: Routes = [
{ path: 'endpage', component: EndPageComponent }
];
url的地址是 http://localhost:4200/endpage?name=huangbiao&age=30
获取参数
import { Component, OnInit } from '@angular/core';
import {ActivatedRoute} from '@angular/router'; @Component({
selector: 'app-end-page',
templateUrl: './end-page.component.html',
styleUrls: ['./end-page.component.scss']
})
export class EndPageComponent implements OnInit {
constructor(public route:ActivatedRoute) { } ngOnInit() {
console.dir(this.route);
debugger
this.route.params.subscribe((data)=>{
console.log(data); // 打印的是一个对象,key为name和age
});
} }
获取参数要依赖注入 route:ActivatedRoute
对象
配置动态路由
// 第一个参数对应路由的name,第二个参数对应路由的age
<a [routerLink]="[ '/endpage/', 'huangbiao','30' ]">endpage</a>
定义路由
const routes: Routes = [
{ path: 'endpage/:name/:age', component: EndPageComponent }
];
url地址是 http://localhost:4200/endpage/huangbiao/30
获取参数
import { Component, OnInit } from '@angular/core';
import {ActivatedRoute} from '@angular/router'; @Component({
selector: 'app-end-page',
templateUrl: './end-page.component.html',
styleUrls: ['./end-page.component.scss']
})
export class EndPageComponent implements OnInit {
constructor(public route:ActivatedRoute) { } ngOnInit() {
console.dir(this.route);
debugger
this.route.params.subscribe((data)=>{
console.log(data); // 打印的是一个对象,key为name和age
});
} }
API js路由跳转
配置动态路由
this.router.navigate(['/newscontent/','1243'])
//this.router.navigate(['/home']);
如果是动态路由,则路由后面的/
是不能少的

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 });
