使用angular

Question

我有一个小标签，其中我显示一个表数据的总结果计数。下面我正在使用一张表，关于那我正在显示数据列表。当我删除表中的一行时，表正在刷新但在该标签中，结果计数没有刷新。这是我的数据。

import { VsnApplicationsServiceProxy, VsnApplicationDto , CreateOrEditVsnApplicationDto  } from '@shared/service-proxies/service-proxies';
@Component({
  selector: 'vsn-applicationmappings',
  templateUrl: './applicationmappings.component.html',
  styleUrls: ['./applicationmappings.component.less'],
  encapsulation: ViewEncapsulation.None,
  animations: [appModuleAnimation()]
})
export class ApplicationMappingsComponent extends AppComponentBase implements OnInit {
  applications: any;
   constructor(
    injector: Injector,
    private _vsnApplicationsServiceProxy: VsnApplicationsServiceProxy,
    private _activatedRoute: ActivatedRoute,

  ) {
    super(injector);
  }
ngOnInit() {
 this._vsnApplicationsServiceProxy.getAll("", "", "", "", "", "", "", 0, 100).subscribe((Applications: any) => {
      this.applications = Applications.totalCount;
      
      console.log(' application value', Applications.totalCount);
    });
     }
      getVsnApplications(event?: LazyLoadEvent) {
    if (this.primengTableHelper.shouldResetPaging(event)) {
      this.paginator.changePage(0);
      return;
    }

    this.primengTableHelper.showLoadingIndicator();

    this._vsnApplicationsServiceProxy.getAll(
      this.filterText,
      this.nameFilter,
      this.businessNameFilter,
      this.vsnApplicationTypeNameFilter,
      this.vsnApplicationCategoryNameFilter,
      this.vsnApplicationSubCategoryNameFilter,
      this.primengTableHelper.getSorting(this.dataTable),
      this.primengTableHelper.getSkipCount(this.paginator, event),
      this.primengTableHelper.getMaxResultCount(this.paginator, event)
    ).subscribe(result => {
      this.primengTableHelper.totalRecordsCount = result.totalCount;
      this.primengTableHelper.records = result.items;
      this.primengTableHelper.hideLoadingIndicator();
    });
  }
  reloadPage(): void {
    this.paginator.changePage(this.paginator.getPage());
  }

  createVsnApplication(): void {
     this.createOrEditVsnApplicationModal.show();
  }

  deleteVsnApplication(vsnApplication: VsnApplicationDto): void {
    this.message.confirm(
      '',
      (isConfirmed) => {
        if (isConfirmed) {
          this._vsnApplicationsServiceProxy.delete(vsnApplication.id)
            .subscribe(() => {
              this.reloadPage();
              this.notify.success(this.l('SuccessfullyDeleted'));
            });
        }
      }
    );
  }

当删除一行时，该表正在刷新并显示更新的记录。但是在结果计数标签中却没有刷新。我在堆栈溢出中进行搜索，发现我们必须像splice（id，1） 但这不起作用，任何建议都会有很大帮助。
