如何导航到兄弟路线？

Question

我们假设我得到了这个路由器配置

export const EmployeeRoutes = [
   { path: 'sales', component: SalesComponent },
   { path: 'contacts', component: ContactsComponent }
];

并已导航SalesComponent到此URL

/department/7/employees/45/sales

现在我想去contacts,但因为我没有绝对路线的所有参数(例如7上面例子中的部门ID ),我宁愿使用相对链接到达那里,例如

[routerLink]="['../contacts']"

要么

this.router.navigate('../contacts')

不幸的是,这不起作用.可能有一个明显的解决方案,但我没有看到它.有人可以帮帮忙吗？

如果您使用的是新路由器(3.0.0-beta2),则可以使用ActivatedRoute导航到相对路径,如下所示:

constructor(private router: Router, private r:ActivatedRoute) {} 

///
// DOES NOT WORK SEE UPDATE
goToContact() {
  this.router.navigate(["../contacts"], { relativeTo: this.r });
}

更新08/02/2019 Angular 7.1.0

current route: /department/7/employees/45/sales

the old version will do: /department/7/employees/45/sales/contacts

根据@ KCarnaille的评论,上述内容不适用于最新的路由器.新方法是添加.parent到this.r这样

    // Working(08/02/2019) 
    goToContact() {
       this.router.navigate(["../contacts"], { relativeTo: this.r.parent });
    }

the update will do: /department/7/employees/45/contacts

RouterLink指令始终将提供的链接视为当前URL的增量:

[routerLink]="['/absolute']"
[routerLink]="['../../parent']"
[routerLink]="['../sibling']"
[routerLink]="['./child']"     // or
[routerLink]="['child']" 

// with route param     ../sibling;abc=xyz
[routerLink]="['../sibling', {abc: 'xyz'}]"
// with query param and fragment   ../sibling?p1=value1&p2=v2#frag
[routerLink]="['../sibling']" [queryParams]="{p1: 'value', p2: 'v2'}" fragment="frag"

该navigate()方法需要一个起点(即relativeTo参数).如果没有提供,导航是绝对的:

constructor(private router: Router, private route: ActivatedRoute) {}

this.router.navigate(["/absolute/path"]);
this.router.navigate(["../../parent"], {relativeTo: this.route});
this.router.navigate(["../sibling"],   {relativeTo: this.route});
this.router.navigate(["./child"],      {relativeTo: this.route}); // or
this.router.navigate(["child"],        {relativeTo: this.route});

// with route param     ../sibling;abc=xyz
this.router.navigate(["../sibling", {abc: 'xyz'}], {relativeTo: this.route});
// with query param and fragment   ../sibling?p1=value1&p2=v2#frag
this.router.navigate(["../sibling"], {relativeTo: this.route, 
    queryParams: {p1: 'value', p2: 'v2'}, fragment: 'frag'});

// RC.5+: navigate without updating the URL 
this.router.navigate(["../sibling"], {relativeTo: this.route, skipLocationChange: true});
