如何使用角度2將動態值傳遞給模態

Question

嗨，我在這里有一個動態數據，其中以下面的按鈕形式顯示它們是代碼

              <ng-container *ngFor="let data of mapData">

                <div *ngIf="data.OrderState==='1'" class="ds">
                  <button [id]="data.DrId" class="btn btn-outline secondary">
                    {{data.Name}}
                  </button>
                </div>
              </ng-container>

現在單擊動態生成的按鈕后，我想發送data.Drid * data.Name到模式輸入字段，以及如何調用動態按鈕上的模式，將它們作為2參數傳遞，並在模式提交時獲取該數據紐扣

下面是bootstrap 4模態代碼，我如何將其應用於發送參數

<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
  Launch demo modal
</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">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal 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">
        ...
      </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>

Answer 1

在模板中，您可以(click)事件調用方法。 即

      <ng-container *ngFor="let data of mapData">

        <div *ngIf="data.OrderState==='1'" class="ds">
          <button [id]="data.DrId" class="btn btn-outline secondary"
(click)="buttonClicked(data.DrId, data.Name)">
            {{data.Name}}
          </button>
        </div>
      </ng-container>

在組件中，創建變量drId和drName並添加buttonClicked方法，然后為這些變量分配來自buttonClicked參數的值。 即

buttonClicked(id, name) {
  this.drId = id;
  this.drName = name;
  `$('#exampleModal').modal('show')`
  // You have id and name here, You can make use of these to display anywhere.
}

要從JavaScript處理模式，請參閱此鏈接-> https://getbootstrap.com/docs/4.0/components/modal/#via-javascript

您可以在引導程序模式模板中綁定這些變量

<!-- 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">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal 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">
        <input class="" id ="" [value]="drId"/>
        <input class="" id ="" [value]="drName">
      </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>
