如何使用角度 2 将动态值传递给模态

Question

您好，我有一个动态数据，下面以按钮的形式显示它们是代码

              <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>

现在单击动态生成的按钮后，我想将 data.Drid * data.Name 发送到模态输入字段，我该如何调用动态按钮单击模态将这些作为 2 个参数传递并在模态提交按钮上获取该数据

下面是 bootstrap 4 模态代码，我如何在发送参数中应用此代码

<!-- 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

在模板中你可以让(click) 事件调用一个方法。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>

在组件中，创建变量drId 和drName 并添加buttonClicked 方法，然后为这些变量分配来自buttonClicked 参数的值。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.
}

要从 JavaScript 处理模态，请参阅此链接 -> https://getbootstrap.com/docs/4.0/components/modal/#via-javascript

您可以在引导模式模板中绑定这些变量

<!-- 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>
