How can I close a modal in Angular 2?

Question

I want user click the Submit button and the modal close automatically.

If I add data-dismiss="modal" in the Submit <button>, it won't run submitComments().

I tried to do something like $('#myModal').modal('hide');, but not succeed.

So how can I close a modal in Angular 2? Thanks

<button type="button" class="btn btn-info" data-toggle="modal" data-target="#myModal">Open Modal</button>

<div id="myModal" class="modal fade">
     <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-body">
                <form (ngSubmit)="submitComments()">
                    <div class="form-group row">
                        <label class="form-control-label col-sm-2">Comments:</label>
                        <div class="col-sm-10">
                            <textarea class="form-control" rows="3"></textarea>
                        </div>
                    </div>
                    <div class="form-group row">
                        <div class="col-sm-offset-2 col-sm-10">
                            <button type="submit" class="btn btn-default">Submit</button>
                        </div>
                    </div>
                </form>
            </div>
        </div>
    </div>
</div>

.

submitComments() {
    // I want to do something like $('#myModal').modal('hide'); here.
}

Using @ViewChild

add #closeBtn to the element with data-dismiss="modal"

<a><i class="fa fa-close" data-dismiss="modal" #closeBtn></i></a>

Component html

<div class="modal fade" id="yourModalId">
  <div class="modal-dialog modal-lg">
    <div class="modal-content">
      <div class="modal-header">
        <a><i class="fa fa-close" data-dismiss="modal" #closeBtn></i></a>
      </div>
      <div class="modal-body">
      </div>
      <div class="modal-footer">
      </div>
    </div>
  </div>
</div>

using this.closeBtn.nativeElement.click(); to trigger click event will close your modal.

Component typescript

import {ViewChild, ElementRef} from '@angular/core';
@Component({
    moduleId: ...,
    selector: '.',
    templateUrl: '.',
    styleUrls: ['.']
})
export class yourClass {
    @ViewChild('closeBtn') closeBtn: ElementRef;

    yourFunction() {
        //do something
        ...
        ...
        //close your modal
        this.closeModal();
    }

    //call this wherever you want to close modal
    private closeModal(): void {
        this.closeBtn.nativeElement.click();
    }
}
