angular跳转和传参

使用routerLink跳转

• <a routerLink=["/exampledetail",id]></a>
• <a routerLink=["/exampledetail",{queryParams:object}] ></a>

使用navigate跳转

　　import { Router } from '@angular/router';

1. this.router.navigate(['user', 1]);
   以根路由为起点跳转
2. this.router.navigate(['user', 1],{relativeTo: route});
   默认值为根路由，设置后相对当前路由跳转，route是ActivatedRoute的实例，使用需要导入ActivatedRoute
3. this.router.navigate(['user', 1],{ queryParams: { id: 1 } });
   路由中传参数 /user/1?id=1
4. this.router.navigate(['view', 1], { preserveQueryParams: true });
   默认值为false，设为true，保留之前路由中的查询参数/user?id=1 to /view?id=1
5. this.router.navigate(['user', 1],{ fragment: 'top' });
   路由中锚点跳转 /user/1#top
6. this.router.navigate(['/view'], { preserveFragment: true });
   默认值为false，设为true，保留之前路由中的锚点/user/1#top to /view#top
7. this.router.navigate(['/user',1], { skipLocationChange: true });
   默认值为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
8. this.router.navigate(['/user',1], { replaceUrl: true });
   未设置时默认为true，设置为false路由不会进行跳转

获取query方式的参数

import { ActivateRoute } from '@angular/router';
public id: any;
snapshot
constructor( public activeRoute: ActivateRoute ) { };
ngOnInit(){
    this.id= this.activeRoute.snapshot.params['id'];
};
queryParams
    ngOnInit(){
        this.activeRoute.queryParams.subscribe(params => {
        this.id = params['id'];
    });
