我正在尝试在 2-3 秒内隐藏清晰的警报，但是使用此代码 t 不显示，我不明白。

 import { Observable} from 'rxjs/Rx';

 public timerAlert: boolean = false;

 ngOnInit() {
   let timer =  Observable.timer(2000, 3000);
        timer.subscribe( () => {
           this.timerAlert = true; --> with this line My alert doesn't show.
        });

    }

html

   <clr-alert  [(clrAlertClosed)]="timerAlert"  [clrAlertClosable]="false" [clrAlertType]="'alert-danger'" *ngIf="errorServer">
       <clr-alert-item>
           <span class="alert-text">
                 {{ this.myMessage.message }}
            </span>
        </clr-alert-item>
    </clr-alert>

[clrAlertClosable]="false" for hidde 'x' in Alert.
[(clrAlertClosed)]="timerAlert" with this, I should show or not the alert.

我可以解决这个... 50%

 import { Observable } from 'rxjs/Rx';
  public timerAlert: boolean = false;

 ngOnInit() {
        let timer = Observable.timer(10, 8000);
        this.timerAlerts(timer);

    }

 private timerAlerts(timer) {
        timer.subscribe(() => {

            if (this.errorServer || this.confirmedServer) {
                this.timerAlert = true; // firstTrue
                this.timerAlert = false;
                this.errorServer = false;
                this.confirmedServer = false;
            }
        });
    }

唯一的问题是...如果您快速插入或修改时间不会开始，也就是说，如果您在 7 秒内修改某些内容，则消息确认只有 1 秒...

html

 <clr-alert  [(clrAlertClosed)]="timerAlert"  [clrAlertClosable]="false" [clrAlertType]="'alert-danger'" *ngIf="errorServer">
       <clr-alert-item>
           <span class="alert-text">
                 {{ this.myMessage.message }}
            </span>
        </clr-alert-item>
    </clr-alert>

     <clr-alert  [(clrAlertClosed)]="timerAlert"  [clrAlertClosable]="false" [clrAlertType]="'alert-success'" *ngIf="confirmedServer">
         <clr-alert-item>
             <span class="alert-success">
                 {{ this.myMessage.message }}
             </span>
         </clr-alert-item>
    </clr-alert>

我该如何解决这个问题？
