I want to display/hide routerLink
s based on some Data
from the router. The directive is done, but I'm missing the most essential part...
For example I have the following router config (omitted components):
[
{ path: '', children: [
{ path: 'foo', children: [
{ path: 'bar', data: { requiredPermissions: ['a', 'b'] } }
]}
]},
{ path: 'baz', data: { requiredPermissions: ['c'] }, children: [
{ path: ':id' }
]}
]
Now I'd like to ask the Router
for the Route
that would be used if the routerLink
is /foo/bar
or /baz/123
.
I looked though the Router
source code ( https://github.com/angular/angular/blob/master/modules/%40angular/router/src/router.ts ), but couldn't find some easy way to do this. Especially how it handles these :id
variables.
Of course I could iterate over Router.config
, going deeper and deeper. But then I'd have to parse those variables, regular expressions, etc. There must be an easier way, because the angular router must internally do all this stuff, too.
Do you have any idea / solution?
You could fire router.navigateByUrl
, wait for RouteRecognized
event and cancel navigation (for example using custom Guard). RouteRecognized
will have all necessary information. Obviously it is bad solution.
There is another approach, you could create additional structure (kinda map), that should contain path + data. For example structure has path struct.baz-route={url:'baz/:id', perm: ['c']}
, then [routerLink]="struct.baz-route.url.replace(':id', x)"
, then *ngIf="struct.baz-url.perm.indexOf('c')>-1"
.
hey if you want the data from current route than you can do like this to get that
import {ActivatedRoute} from '@angular/router';
export class Component {
constructor(private route: ActivatedRoute){
let pathroots = this.route.pathFromRoot;
let pathurl = '';
pathroots.forEach(path => {
path.url.subscribe(url => {
url.forEach(e => {
pathurl += e + '/';
});
});
});
console.log(pathurl,'*******************');
}
}
