可以添加一个(click)事件，当用户点击输入框时，调用markAsTouched()方法标记为已触摸。这样就可以让ngModel及时更新变量的值了。例如：

<input (change)="onChange(input.value)" (blur)="markAsTouched()" (click)="markAsTouched()" [autocomplete]="autocomplete" [ngClass]="invalidReason && input.value.length>0?'ng-invalid ng-dirty':''" [class.ng-dirty]="elRef.nativeElement.classList.contains('ng-touched')" [placeholder]="placeholder" [type]="type" class="w-full" id="{{id}}-input" [required]="required" pInputText [(ngModel)]="value" [step]="step" [min]="min" [max]="max" [disabled]="disabled" #input="ngModel"
