使用参数定义路由时 angular 中的路由问题

Question

i have two routes defined like this

children: [
                            {
                                path: 'Templates', component: TemplatesComponent
                            },
                            {
                                path: 'AddEditTemplate/:id', component: AddTemplatesComponent
                            }]

I have "cancel" button on AddTemplatesComponent view

<a class="btn btn-default no-margin" [routerLink]="['../Templates']">Cancel</a>

But clicking on cancel button it not navigate to "Templates" component and the url changed from "/AddEditTemplate/5" to "/AddEditTemplate/Templates". But url should change to "/Templates".

What am i doing wrong? please help.

In fact you have to go up 2 routes in the path. For example, let's suppose you're at root/AddEditTemplate/2 . If you go up 1 route in the path, you'll be at root/AddEditTemplate . So, to be in root again to get to root/Templates , you should go up 2 routes in the path:

<a class="btn btn-default no-margin" [routerLink]="['../../Templates']">Cancel</a>

Checkout this Stackblitz demo => focus just in the files inside module-1 folder.

[UPDATE]: If you want to navigate programmatically, you can use the navigate method of the Router with 2 arguments: the same route as above and a config options containing the relativeTo attribute specifying the current route as a starting point to calculate the relative paths. According to the docs : If no starting route is provided, the navigation is absolute .

constructor(
  private _router: Router,
  private _activatedRoute: ActivatedRoute
) {}

...

_navigate() {
  this._router.navigate(['../../Templates'], {
    relativeTo: this._activatedRoute
  });
}
