angular跳轉和傳參

使用routerLink跳轉

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

使用navigate跳轉

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

1. this.router.navigate(['user', 1]);
   以根路由為起點跳轉
2. this.router.navigate(['user', 1],{relativeTo: route});
   默認值為根路由，設置后相對當前路由跳轉，route是ActivatedRoute的實例，使用需要導入ActivatedRoute
3. this.router.navigate(['user', 1],{ queryParams: { id: 1 } });
   路由中傳參數 /user/1?id=1
4. this.router.navigate(['view', 1], { preserveQueryParams: true });
   默認值為false，設為true，保留之前路由中的查詢參數/user?id=1 to /view?id=1
5. this.router.navigate(['user', 1],{ fragment: 'top' });
   路由中錨點跳轉 /user/1#top
6. this.router.navigate(['/view'], { preserveFragment: true });
   默認值為false，設為true，保留之前路由中的錨點/user/1#top to /view#top
7. this.router.navigate(['/user',1], { skipLocationChange: true });
   默認值為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
8. this.router.navigate(['/user',1], { replaceUrl: true });
   未設置時默認為true，設置為false路由不會進行跳轉

獲取query方式的參數

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'];
    });
