Configure Modal Dialog

I have an issue configuring a modal dialog in angular 2

I am trying to delete a user and I want to have buttons like 'Yes' and 'No'. Here is a shortcut of the modal. enter image description here

This is the function:

 public deleteUser(i: number) {
    this.modal.alert().size('lg')
      .title('A simple Alert style modal window')
      .body(`
            <h4>Are you sure you want to delete the user?</h4>`)
      .open();

  }

For modal component I am using Modal from angular2-modal/plugins/bootstrap <<import { Modal } from 'angular2-modal/plugins/bootstrap';>>

Could someone tell me how to remove the 'Ok' button and Adding the 'Yes' and 'No' buttons, please?

Thank you

You have chosen the wrong modal method, alert() from the Bootstrap plugin offered by Angular 2 Modal.

Use the .confirm() modal instead.

Check the modal code Generator.

You can create custom modal component like:

export class CustomModalContext extends BSModalContext {
  yesCallback: () => Promise<any>;
}

@Component({
  selector: 'modal-content',
  template: `
    <div class="modal-content">
        <div class="modal-header">
            <button  class="close" type="button" (click)="dialog.close()">
                <span aria-hidden="true">×</span>
            </button>
            <h3 class="modal-title">Confirmation</h3>
        </div>


        <div class="modal-body">
            <h4>Are you sure you want to delete the user?</h4>
        </div>

        <div class="modal-footer">
            <button class="btn btn-primary" (click)="yes()">Yes</button>
            <button class="btn" (click)="dialog.close()">No</button>
        </div>
    </div>`
})
export class CustomModal implements CloseGuard, ModalComponent<CustomModalContext> {
  context: CustomModalContext;

  constructor(public dialog: DialogRef<CustomModalContext>) {
    this.context = dialog.context;
    dialog.setCloseGuard(this);
  }

  yes() {
    this.context.yesCallback()
      .then(() => this.dialog.close())
  }

  beforeDismiss(): boolean {
    return true; // prevent closing modal by using Esc
  }
}

Then add it to declarations and entryComponents of your @NgModule metadata

  declarations: [ App, CustomModal ],
  entryComponents: [CustomModal],
  bootstrap: [ App ]
})
export class AppModule {}

And use it as follows

deleteUser() {
   return this.modal.open(CustomModal,
       overlayConfigFactory({
           yesCallback: () => {
               alert('Deleting');
               return Promise.resolve(null)
           }
       }, BSModalContext));
 }

You can add .footerClass('no-display') before your open(), and define this CSS class like so : 

no-display {
    display: none;
}
