推荐答案

您可以在模式对话框中添加关闭按钮HTML，并添加模板变量#closebutton

You can add close button HTML in your modal dialog and add template variable #closebutton

在ts代码中，您调用this.closebutton.nativeElement.click();关闭模式对话框.

In ts code, you call this.closebutton.nativeElement.click(); to close modal dialog.

HTML

<div class="container">
  <h2>Modal Close</h2>
  <!-- Trigger the modal with a button -->
  <button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open</button>

  <!-- Modal -->
  <div class="modal fade" id="myModal" role="dialog">
    <div class="modal-dialog">

      <!-- Modal content-->
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" #closebutton class="close" data-dismiss="modal">&times;</button>
          <h4 class="modal-title">Modal Header</h4>
        </div>
        <div class="modal-body">
            <p>Content here</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-danger" id="closeModal"  (click)="onSave()">Save</button>
         </div>
      </div>
    </div>
  </div>

</div>

TS

export class AppComponent implements OnInit {
  @ViewChild('closebutton') closebutton;

  constructor(private fb: FormBuilder) { }

  public ngOnInit() {

  }

  public onSave() {
    this.closebutton.nativeElement.click();
  }
}

更新:

我还有另一种解决方案，没有关闭按钮的窍门.

I have another solution without trick on close button.

第一步，需要通过npm命令安装jquery和bootstrap.

First step you need install jquery and bootstrap by npm command.

第二，您需要在组件中添加declare var $ : any;

Second you need add declare var $ : any; in component

并且可以使用$('#myModal').modal('hide'); onSave()方法上

And use can use $('#myModal').modal('hide'); on onSave() method
