SweetAlert删除角度错误5

使用Angular5,我试图在代码中使用sweetAlert for delet选项,但出现了一些错误:

我使用的功能和官方的一样 link

这是.ts中的代码

import * as _swal from 'sweetalert';
import { SweetAlert } from 'sweetalert/typings/core';
const swal: SweetAlert = _swal as any;

@Component({
  selector: 'app-clients',
  templateUrl: './clients.component.html',
  styleUrls: ['./clients.component.scss']
})
export class ClientsComponent implements OnInit {

  pageClients:any;

   ngOnInit() {
    this.doSearch();
    this.getAllClientsList();
  }

  delete(p:Clients){

    swal({
          title: "Are you sure?",
          text: "Once deleted, you will not be able to recover this imaginary file!",
          icon: "warning",
          buttons: true,
          dangerMode: true,
        })
          .then((willDelete) => {
            if (willDelete) {
                  this.clientService.deleteClient(p.id)
                  .subscribe(data=>{
                  this.pageClients.content.splice(
                  this.pageClients.content.indexOf(p),1
                     );
                  },err=>{
                  console.log(err);
                   })
              swal("Poof! Your imaginary file has been deleted!", {
                icon: "success",
              });
            } else {
              swal("Your imaginary file is safe!");
            }
          });
    }
}

如何解决这个问题?

编辑

delete(p:Clients){

    swal({
      title: "are you sur ?",
      text: " nce deleted, you will not be able to recover this imaginary file!!",
      type: 'warning',
      showConfirmButton: true,
      showCancelButton: true
    })
      .then((willDelete) => {

        if (willDelete) {

          this.clientService.deleteClient(p.id)
            .subscribe(data=>{
              this.pageClients.content.splice(
                this.pageClients.content.indexOf(p),1
              );
            },err=>{
              console.log(err);
            })

          swal({
           title: " great",
            type: 'success',
          });
        } else {
          swal("you have not deleted this client yet ");
        }
      });
  }

当出现此警报时,每当选择“确定”或“取消”时,我总是收到“很好”的警报。

当我试图打印这个时,我知道它总是执行第一个if(willdelete),所以不管我选择ok还是cancel,这个客户机都会被删除。
