                                                   id="d1" formControlName="startDate" (ngModelChange)="changeDateRange()" ngbDatepicker #d1="ngbDatepicker" readonly>
                                            <img class="imgCalendar" (click)="d1.toggle()" src="../../assets/img/Slicing/b_event_icon@2x.png" />

                                    </div>
                                </div>

单击日期范围后，选择开始日期。然后，如果要选择“每周一次”，请单击“希望”，然后单击“开始日期”。
