Question

我正在尝试在Angular项目中使用Bootsrap Modal询问“您确定删除此项目”

但是当我将itemID发送到模态时，即使我选择要删除的第4个项目，也始终会得到第一个itemId

<div class="col-sm-3" *ngFor="let item of florArray">
    <div class="card shadow p-1 mb-2 bg-white rounded" style="width: 100%;">
      <div class="card-body">
        <h3>{{item.cubeAreaName}}</h3>
        <hr>
        <br>
        <button class="btn btn-warning btn-block" (click)="editZone(item.cubeAreaID)" type="submit">Edit</button>
        <button class="btn btn-danger btn-block" data-toggle="modal" data-target="#exampleModalCenter" type="submit">Delete</button>
      </div>
    </div>

    <div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle"
      aria-hidden="true">
      <div class="modal-dialog modal-dialog-centered" role="document">
        <div class="modal-content">
          <div class="modal-header">
            <h5 class="modal-title" id="exampleModalLongTitle">Delete It ?</h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
              <span aria-hidden="true">&times;</span>
            </button>
          </div>
          <div class="modal-body">
            If you delete this section please dont forget that you will lose your all related tables that you have
            created for this section
          </div>
          <div class="modal-footer">
            <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
            <button type="button" class="btn btn-danger" data-dismiss="modal" (click)="deactiveZone(item.cubeAreaID)">Delete</button>
          </div>
        </div>
      </div>
    </div>

认为我有五个列出的项目。然后我单击了第四项以删除。

（click）=“ deactiveZone（item.cubeAreaID）

模式按钮中存在的此代码部分始终删除第一项。

你能告诉我我的错误在哪里吗？

引导程序模式不能那样工作。我周围也有同样的问题。您可以做的就是将ID存储在一个临时变量中并使用它。

TS：

. . .
tempIDSelect : number
. . .

HTML：

. . .
// Button to toggle delete modal
<button class="btn btn-danger btn-block" data-toggle="modal" data-target="#exampleModalCenter" type="submit" (click)="tempIDSelect=item.CubeAreaID">Delete</button>
. . .
// Button inside modal
<button type="button" class="btn btn-danger" data-dismiss="modal" (click)="deactiveZone(tempIDSelect)">Delete</button>
. . .
