How to hide bootstrap modal in angular

Question

I am using bootstrap modal but when I hide it from code-behind it shows the error below.

I am using angular6.

Code

<div #exampleModal class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel"
        aria-hidden="true">

  @ViewChild('exampleModal') public exampleModal: ElementRef;

 this.exampleModal.hide();

Error message

ERROR TypeError: this.exampleModal.hide is not a function

Solution

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

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();
  }
}

Update:

I have another solution without trick on close button.

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

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

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

please explain why your solution works. The question itself is ambiguous, so you should ask questions in comment section to clarify the question rather than jumping to write an answer.

Hi all. I add @ViewChild as ModalDirective instead of ElementRef. So you can use show and hide methods because that viewchild is a modal.
