Question

我们假设我有这个路由器配置

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

已通过此网址导航至SalesComponent

/department/7/employees/45/sales

现在我想转到contacts，但因为我没有绝对路线的所有参数（例如上面例子中的部门ID，7）我会我喜欢使用相对链接到达那里，例如

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

或

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

遗憾的是不起作用。可能有一个明显的解决方案，但我没有看到它。有人可以帮忙吗？

如果您使用新路由器（3.0.0-beta2），您可以使用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。新方法是将.parent添加到this.r以便

    // 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"

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

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});

如何导航到兄弟路线？
