Question

需求是使用ngFor获取列表，单击选项卡以显示引导模式，但每个模态ID在列表中是相同的，导致每个模态的内容是第一次采访，现在的想法是获取索引，索引将传递给id。现在的问题是如何传入索引，这个想法是正确的吗？

<tr *ngFor="let interview of interviews; let i = index" role="row" class="gradeA">
   <td class="col-sm-2" style="text-align: left;">{{ interview.company.name }}</td>
   <td class="col-sm-1" style="text-align: left;">{{ interview.inviter.real_name }}</td>
   <td class="col-sm-1" style="text-align: left;" *ngIf="interview.interviewee.user_id==0">未知</td>
   <td class="col-sm-1" style="text-align: left;" *ngIf="interview.interviewee.user_id!=0">{{ interview.interviewee.real_name }}</td>
   <td class="col-sm-1" style="text-align: left;" *ngIf="interview.notice_type==0">
   <a data-toggle="modal" data-target="modal">短信</a>
     <div class="modal fade" id="modal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
        <div class="modal-dialog">
           <div class="modal-content">
              <div class="modal-header">
                 <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                 <h4 class="modal-title">通知内容</h4>
              </div>
           <div class="modal-body">
              <span style="font-weight:bold;">公司名称：</span><p>{{ interview.company.name }}</p>
              <span style="font-weight:bold;">面试官：</span><p>{{ interview.inviter.real_name }}</p>
              <span style="font-weight:bold;">应聘者：</span><p>{{ interview.interviewee.real_name }}</p>
              <span style="font-weight:bold;">通知内容：</span><p>{{ interview.notice_content }}</p>
           </div>
         </div>
       </div>
     </div>
  </td>

Answer 1

我们可以使用此解决方案，只需创建1个对话框弹出窗口并将其传递给selectedInterview对象。

selectedInterview: any;
showPopup(interviewObj) {
   this.selectedInterview = interviewObj;
}

我们将模板分为2个部分，1个用于循环访问，1个用于对话框弹出

<tr *ngFor="let interview of interviews; let i = index" role="row" class="gradeA">
   <td class="col-sm-2" style="text-align: left;">{{ interview.company.name }}</td>
   <td class="col-sm-1" style="text-align: left;">{{ interview.inviter.real_name }}</td>
   <td class="col-sm-1" style="text-align: left;" *ngIf="interview.interviewee.user_id==0">未知</td>
   <td class="col-sm-1" style="text-align: left;" *ngIf="interview.interviewee.user_id!=0">{{ interview.interviewee.real_name }}</td>
   <td class="col-sm-1" style="text-align: left;" *ngIf="interview.notice_type==0">
   <a data-toggle="modal" (click)="showPopup(interview)" data-target="modal">短信</a>
</td>

请注意： ng-container 检查selectInterview是否未定义以在弹出窗口中显示

<div class="modal fade" id="modal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title">通知内容</h4>
      </div>
      <div class="modal-body">
        <ng-container *ngIf="selectedInterview !== undefined">
          <span style="font-weight:bold;">公司名称：</span><p>{{ selectedInterview.company.name }}</p>
          <span style="font-weight:bold;">面试官：</span><p>{{ selectedInterview.inviter.real_name }}</p>
          <span style="font-weight:bold;">应聘者：</span><p>{{ selectedInterview.interviewee.real_name }}</p>
          <span style="font-weight:bold;">通知内容：</span><p>{{ selectedInterview.notice_content }}</p>
        </ng-container>
      </div>
    </div>
  </div>
</div>
