弹出窗口中的角度引导日期范围选择器？

Question

我正在尝试使用 ng-bootstrap 在我的 Angular 应用程序中显示日期范围选择器。我的代码如下所示：

<ngb-datepicker #dp ngModel (ngModelChange)="onDateChange($event)" [displayMonths]="2" [dayTemplate]="t">
            </ngb-datepicker>

            <ng-template #t let-date="date" let-focused="focused">
              <span class="custom-day"
                    [class.focused]="focused"
                    [class.range]="isFrom(date) || isTo(date) || isInside(date) || isHovered(date)"
                    [class.faded]="isHovered(date) || isInside(date)"
                    (mouseenter)="hoveredDate = date"
                    (mouseleave)="hoveredDate = null">
                {{ date.day }}
              </span>
            </ng-template>

我应该如何在弹出窗口中显示上述范围选择器？

根据答案，我尝试了以下操作，但点击时看不到弹出窗口：

 <!-- Button trigger modal -->
          <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
            Pick Date Range
           </button>

    <div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
      <div class="modal-dialog" role="document">
        <div class="modal-content">
          <div class="modal-header">
            <h5 class="modal-title" id="exampleModalLabel">Optional title</h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
              <span aria-hidden="true">&times;</span>
            </button>
          </div>
          <div class="modal-body">

            <ngb-datepicker #dp ngModel (ngModelChange)="onDateChange($event)" [displayMonths]="2" [dayTemplate]="t">
            </ngb-datepicker>

            <ng-template #t let-date="date" let-focused="focused">
              <span class="custom-day"
                    [class.focused]="focused"
                    [class.range]="isFrom(date) || isTo(date) || isInside(date) || isHovered(date)"
                    [class.faded]="isHovered(date) || isInside(date)"
                    (mouseenter)="hoveredDate = date"
                    (mouseleave)="hoveredDate = null">
                {{ date.day }}
              </span>
            </ng-template>
          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-primary">Save changes</button>
          </div>
        </div>
      </div>
    </div>

如果您不想使用完整的弹出窗口，而是在弹出窗口中显示日期范围选择器，我使用 ng-bootstrap 和 moment.js 做了一个简单的演示：https://stackblitz.com/edit/ng-bootstrap-date-range

它大量借鉴了 ng-bootstrap 提供的官方range selection demo。

要在 Bootstrap 4 弹出窗口/模式中显示您的日期范围选择器，您可以使用以下 HTML 作为模板（单击下面的“运行代码 sn-p”按钮进行实时测试）。

对ng-bootstrap 用户很重要：

popper.js 是 Bootstrap 4 中所有弹出或下拉内容所必需的。因此，请确保将其加载到您的应用程序中。

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
  Click this button!
</button>

<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">

        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        Your date-range-picker code goes here...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>

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

感谢您解释的回复和解决方案，是的，虽然我们只使用 bootstrap 4，但我们可能需要上述依赖项。但是在我们使用 ng-bootstrap 时这些都不需要，我是从Ng-bootstrap 的官方文档中得到的。

请添加您宝贵的 cmets，我是学习 Angular 及其扩展的新手，也请清除我的疑问。
