如何解决我尝试更改ng-template角度上的值后，NgbPopover会立即关闭

我将ngbPopover与ngb-datepicker和ngb-timepicker一起使用

<div class="input-group">              
    <input class="form-control" formControlName="createdStartDate" disabled="true"
      [value]="createdStartDateValue?(createdStartDateValue|date:'dd/MM/yyyy,HH:mm'):createdStartDateLabel">               
    
        <div class="input-group-append">
          <button class="btn btn-outline-secondary calendar" type="button" placement="bottom" popoverTitle="Select Date Time"  [ngbPopover]="dateTimePicker"  (click)="$event.stopPropagation()"></button>
          <ng-template #dateTimePicker>
            <ngb-datepicker [ngModel]="createdStartDate" (ngModelChange)="getCreatedStartDatetime()" [ngModelOptions]="{standalone:true}">
            </ngb-datepicker>
            
            <ngb-timepicker [ngModel]="createdStartTime" (ngModelChange)="createdStartTime=$event;getCreatedStartDatetime()" [ngModelOptions]="{standalone:true}">
            </ngb-timepicker>              
          </ng-template>
        </div>
    </div>

一旦我尝试在Timepicker中添加一些输入，它就会关闭。 如何阻止这种情况发生？

解决方法

css

.dropdown-toggle.calendar::after
{
  border:0
}
button.calendar,button.calendar:active {
  width: 2.75rem;
  background-image: url('data:image/png;base64,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') !important;
  background-repeat: no-repeat;
  background-size: 23px;
  background-position: center;
}

html

<div class="form-group">
    <div class="input-group">
        <input class="form-control" placeholder="yyyy-mm-dd" [attr.disabled]="true"
         name="dp" >
        <div ngbDropdown class="input-group-append d-inline-block" placement="bottom-right">
            <button class="btn btn-outline-secondary calendar" id="dropdownBasic1" ngbDropdownToggle></button>
            <div ngbDropdownMenu aria-labelledby="dropdownBasic1">
                Your calendar and your timer
            </div>
        </div>
    </div>
</div>

您也可以使用svg，例如

.dropdown-toggle.calendar2::after
{
  border:0
}

    <div class="form-group">
        <div class="input-group">
            <input class="form-control" placeholder="yyyy-mm-dd" [attr.disabled]="true"
             name="dp" >
            <div ngbDropdown class="input-group-append d-inline-block" placement="bottom-right">
                <button class="btn btn-outline-secondary calendar2" id="dropdownBasic1" ngbDropdownToggle>
                    <svg width="1em" height="1em" viewBox="0 0 16 16" class="bi bi-calendar" fill="currentColor" xmlns="http://www.w3.org/2000/svg">
                  <path fill-rule="evenodd" d="M3.5 0a.5.5 0 0 1 .5.5V1h8V.5a.5.5 0 0 1 1 0V1h1a2 2 0 0 1 2 2v11a2 2 0 0 1-2 2H2a2 2 0 0 1-2-2V3a2 2 0 0 1 2-2h1V.5a.5.5 0 0 1 .5-.5zM1 4v10a1 1 0 0 0 1 1h12a1 1 0 0 0 1-1V4H1z"></path>
                    </svg>
                </button>
                <div ngbDropdownMenu aria-labelledby="dropdownBasic1">
                    Your calendar and your timer
                </div>

            </div>
        </div>
    </div>
