                <input size="16" name="checkOutDate" id="checkOutDate" type="text" style="height:30px;" value="" readonly onchange="showRoomBooking(this.value);">
                <span class="add-on" style="height:30px;"><i class="icon-remove"></i></span>
                <span class="add-on" style="height:30px;"><i class="icon-th"></i></span>
            </div>
            <input type="hidden" id="dtp_input3" value="" /><br/>
            </td>
        </div>

我想将checkOutDate的日期设置为与选择checkInDate相同的日期，但是我不能这样做。有人可以帮我吗？

Answer 1

this.selectLoadings$.subscribe(
  loading => (this.isLoading = loading.directionsByBranch[this.branchId])
);

this.selectedDataByBranch$
      .pipe(filter(data => Object.keys(data).length > 0))
      .subscribe(selectedDataByBranch => {
        this.trainsDatasets = this.getDatasets(selectedDataByBranch);
        this.context = this.chartRef.nativeElement; ### Error undefined chartRef

您可以在 checkinDate 上捕获事件 changeDate ，然后更新 checkoutDate 值

P / S：您应该使用摘要功能来显示您的情况，如下所示

$.fn.datepicker.defaults.format = "mm/dd/yyyy";
let dateElm1 = $('.datepicker1');
let dateElm2 = $('.datepicker2');
dateElm1.datepicker({});
dateElm2.datepicker({});

dateElm1.on('changeDate', function (data) {
  dateElm2.datepicker('update', data.date);
});
