通过域名跳转的方式获取参数(http://localhost:4200/second/110?productId=1&title=moon)
这种方式配置路由,其中:id是必需的参数,其它的是可配的,写在?后面:
{ path: ‘second/:id‘, component: SecondComponent },
通过ts代码跳转:
this.router.navigate([‘/second‘,110], { queryParams: { productId: ‘1‘, title: ‘moon‘ } });
获取【:id】参数的方式:
constructor(private route: ActivatedRoute, private router: Router) { } var id = this.route.snapshot.paramMap.get(‘id‘);
在comoent中需要这么获取‘?’ 后面的参数,将参数写在queryParams里
this.router.navigate([‘/second‘,110], { queryParams: { productId: ‘1‘, title: ‘moon‘ } });
通过ActivatedRoute来获取
constructor(private route: ActivatedRoute, private router: Router) { } ngOnInit() { var id = this.route.snapshot.paramMap.get(‘id‘); this.name = id; console.log(id); this.route.queryParams.subscribe(param => { console.log(param); console.log(param.title); console.log(param[‘title‘]); console.log(param.productId); console.log(param[‘productId‘]); }); }
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是跳转前的路径,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
9.页面里url路转写法
<nav> <a routerLink="/heroes/{{id}}">点击查看文章详情</a> <!--数组格式传参,注是第二种试的routerLink是用[]包括--> <a [routerLink]="[‘/heroes‘, num]">点击查看文章详情</a> </nav>
