data-target - Angular

Question

I am displaying a dialog by using HTML directly

<!-- Dialog -->
      <div class="modal fade" id="exampleModalCenter" 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">
              <h3 class="modal-title" id="exampleModalLongTitle">Something went wrong</h3>
              <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                <span aria-hidden="true">&times;</span>
              </button>
            </div>
            <div class="modal-body">
              <h5 class="modal-title" id="exampleModalLongTitle">Maximum 10 messages selected</h5>
            </div>
            <div class="modal-footer">
              <button type="button" class="btn btn-primary">Ok</button>
            </div>
          </div>
        </div>
      </div>

<button data-toggle="modal" data-target="#exampleModalCenter">RunIt</button>

but I would like to do something previously so I would like to execute data-toggle="modal" data-target="#exampleModalCenter" by javascript using (click)

So basically this would be the steps:

1- (click)="test()"

2- execute data-toggle="modal" data-target="#exampleModalCenter" by javascript in test()

to get the DIV that contains it, I have tried:

test(){
    var dialog= <HTMLDivElement>document.getElementById(exampleModalCenter);
  }

but I can not find the exampleModalCenter

Answer 1

you should be using attr.data-target

<button data-toggle="collapse" 
        [attr.data-target]="'#exampleModalCenter">RunIt
</button>

Answer 2

Firstly, you must add click method 'test' to button. Change your modal's class name as 'modal fade'. And after, your ts file must be like this:

@ViewChild('exampleModalCenter') exampleModalCenter;

test() {
  this.exampleModalCenter.nativeElement.className = 'modal fade show';
}
