I have two page with two components:
*PAGES:*
HOME & ABOUT
with two components
*COMPONENTS:*
Home.component & About.component
When I redirect from Home to About page and vice versa, I want to call a
Webapi before it routes to another page
I have tried 2 things:
1. ngOnDestroy
2. Subscribe Router Events
Example: Let's say I am navigating from *Home => About* page, so inside the
home component method, Below are the two cases
Home.component.ts :::: Calling Webapi method inside *ngOnDestroy* method.
*------------------------------------------ ngOnDestroy
---------------------------------------------------------*
*public ngOnDestroy(): void {*
this.updateChanges(); *// Indside this method http call is there*
// Unsubscribe from all subscriptions
this._unsubscribeAll.next();
this._unsubscribeAll.complete();
*}*
*----------------------------------------------- Router
------------------------------------------------------------*
Home.component.ts :::: Calling Webapi by Subscribing *Router* change events
*public ngOnDestroy(): void {*
this._router.events.subscribe((ev: Event) => {
if (ev instanceof NavigationStart) {
this.updateChanges(); *// Indside this method http call is
there*
}
}
);
*}*
*---------------------------------------------------------------------------------------------------------------------*
*PROBLEM is: Inside network tab in browser I can see that Webapi is getting
called but status is showing Cancelled. Any idea why?*
