Troubleshooting the issue of the Delete Service not functioning properly within Angular

ListStore.ts file

export class ListstoreComponent implements OnInit {
  rawlist;
  name = '';
  id = '';
  storeid = "";
  store: Store;

  constructor(private api: APIService, private router: Router, private route: ActivatedRoute, private cookieService: CookieService) { }

  ngOnInit() {
    this.fetchStoreList();

  }

  //fetch store list
  async fetchStoreList() {
    this.rawlist = await this.api.ListStores();
    this.storelist = this.rawlist.items;
  }
  //delete store
  async deleteStore(id) {
  if (window.confirm('Are you sure, you want to delete?')){
    await this.api.DeleteStore(id).catch(data => {
      this.refreshStoreList();
    })
  }
}

HTML File

 <button type="button" class="btn btn-primary btn-gap" (click)="deleteStore(Store.id)">Close Ticket</button>

I'm removing the list and updating database. I am uncertain whether catch() would function as expected. I attempted subscribe but it did not work.

Answer №1

Your event handler needs to handle the asynchronous nature of the call instead of passing it up to the HTML content.

deleteStore(id): void {
  if (!window.confirm('Are you sure, you want to delete?')){
    return;
  }

  this.api.DeleteStore(id).then(message => {
    // handle response
  });
}

Edit:

You could manage it in the HTML, but you'd have to return a promise from the event handler, leading to more code cluttering your HTML structure.

If you prefer using the async await syntax, you can achieve the same functionality with the following approach:

async deleteStore(id): void {
  if (!window.confirm('Are you sure, you want to delete?')){
    return;
  }

  const message = await this.api.DeleteStore(id);
  // handle response
}
