我有一个angular2应用程序,其后端是在
java中.我有一份客户名单.当我单击以删除客户时,客户将被删除,但列表不会更新.如果我手动刷新页面,则列表会更新.我尝试在delete方法的订阅中路由到列表组件,但这不起作用.
列表customers.component.html <tr [class.warning]="customer.isDefault == 1" *ngFor="let customer of customers | orderBy:['firstName'] | search:searchCustomer.value;let serial = index"> <td>{{ serial+1 }}</td> <td>{{ customer?.firstName+' '+customer?.lastName}}</td> <td>{{ customer.email}}</td> <td>{{ customer.mobileNumber}}</td> <td>{{ customer.streetAddress}}</td> <td>{{ customer.priceList?.name}}</td> <td><a [routerLink]="['/loggedIn','customer','edit',customer.id ]"><i class="fa fa-edit fa-2x"></i></a></td> <td><a (click)="delete(customer)"><i class="fa fa-trash-o fa-2x"></i></a></td> </tr> 列表customers.component.ts ngOnInit() { this.refreshCustomersList(); } delete(customer) { this.userService.delete(customer.id) .subscribe( success=> { var index = this.customers.indexOf(customer,0); if (index > -1) { this.customers.splice(index,1); } } ) } refreshCustomersList() { this._authHttp.get( this.appService.getApiUrl() + "api/customer/list" ) .map(res=>res.json()) .subscribe( successResponse=> { this.customers = successResponse.data.customers; },() => console.log("Request Completed") ) } } 解决方法
尝试调用this.refreshCustomersList();在您的删除功能中,如下所示:
delete(customer) { this.userService.delete(customer.id) .subscribe( success=> { var index = this.customers.indexOf(customer,0); if (index > -1) { this.customers.splice(index,1); this.refreshCustomersList(); } } ) } 这将在删除客户后更新customers数组.
