I am using Angular 5 library, I want to navigate to the current URL with reload (refresh) the whole component, not the page, I have read about navigation to current URL in Angular document.
And that it is what I need:
/**
* Define what the router should do if it receives a navigation request to the current URL.
* By default, the router will ignore this navigation. However, this prevents features such
* as a "refresh" button. Use this option to configure the behavior when navigating to the
* current URL. Default is 'ignore'.
*/
onSameUrlNavigation: 'reload' | 'ignore';
Now, I have tried to set the onSameUrlNavigation
property to reload
and then navigate to the same URL, but nothing happend, like this:
this.router.onSameUrlNavigation = 'reload';
this.router.navigate(['view'], { queryParams: { QueryUUID: selectedId } });
Anyone who has used this before can help?
I have found this workaround method since the onSameUrlNavigation
property in Angular 5.1 is not what I need.
I just need to override shouldReuseRoute
, so added an exception for the component route that I want to refresh, if the current and future route are equal view
.
And also I can navigate to other routes without problems, even for navigate from Angular Material
sidenav
.
this.router.routeReuseStrategy.shouldReuseRoute = function (future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot) {
if (future.url.toString() === 'view' && curr.url.toString() === future.url.toString()) {
return false;
}
return (future.routeConfig === curr.routeConfig);
};
Update:
For those they want to use the new onSameUrlNavigation
property in Angular 5.1 you can refer to this blog:
Update:
It is better to create a custom RouteReuseStrategy
that override the default behavior, here it is how I do that:
export class AppRouteReuseStrategy implements BaseRouteReuseStrategy {
// all other methods will be the same as the default
/*
* Determines if a route should be reused.
* This strategy returns `true` when the future route config and current route config are identical.
*
* but we want to refresh the route if the data.refreshComponent is true in the route definition
* */
shouldReuseRoute(future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot): boolean {
// so we need to check if it is true. if not, we return the default behavior
return future.data.refreshComponent ? false : future.routeConfig === curr.routeConfig;
}
}
Then will add this as a provider
in the AppModule
:
{ provide: RouteReuseStrategy, useClass: AppRouteReuseStrategy }
And the last thing to do is to mark which component you want to refresh in case of navigate to the same route, like this:
const routes: Routes = [
{
path: 'view',
component: ViewComponent,
data: { refreshComponent: true },
}
]
