Angular2 provides a simple way to toggle the visibility of modal boxes on a web page

I'm encountering an issue with the ng2 modal in my template - it's not opening or hiding through my TypeScript code.

    <modal  id='saveeditsmodal'>
  <modal-header>
        <h4 class="modal-title">Editing item(s) in Recently Viewed</h4>
       </modal-header>
      <!-- Modal content-->
      <modal-content>
        <div class="modal-body">
          <p>You have unsaved changes.</p>
        </div>
         <div class="modal-body">
          <p>Are you sure you want to discard these changes?</p>
        </div>
               </modal-content>
     <modal-footer>
          <button type="button" class="btn btn-primary" data-dismiss="modal">Stay On List</button>
          <button type="button" class="btn btn-default" data-dismiss="modal" (click)='closebox()'>Discard</button>
  </modal-footer>
  </modal>

Here is my TypeScript code:

$('#saveeditsmodal').show();

I'm new to using ng2 model, so I'm unsure of how to properly hide or show it. Any suggestions or help would be greatly appreciated. Thank you!

Answer №1

When working with Angular2, it's recommended to minimize the use of jQuery.

If you're utilizing ng2-bootstrap modules and its modal component, consider customizing it by extending the existing ModalModule.

Show the modal using an *ngIf="variableName", like this example:

function show() {
  this.variableName = true
}

Include a ViewChild in your component for the modal:

@ViewChild('componentID') modalCmp: ModalComponent

Your HTML structure could be:

<modal #componentID></modal>

You can enhance the component further by adding @Input() and @Output() variables to control its behavior.

In your code, reference modalCmp as follows:

function showMyModal() {
  this.modalCmp.show()
}

If you have any questions, don't hesitate to ask. Remember to properly declare and import your modal components with Angular2 module loaders.

Upon observation, it seems that he is utilizing two public functions for the operation of opening and closing.

 open(...args: any[]) {
        if (this.isOpened)
            return;

        this.isOpened = true;
        this.onOpen.emit(args);
        document.body.appendChild(this.backdropElement);
        window.setTimeout(() => this.modalRoot.nativeElement.focus(), 0);
        document.body.className += " modal-open";
    }

    close(...args: any[]) {
        if (!this.isOpened)
            return;

        this.isOpened = false;
        this.onClose.emit(args);
        document.body.removeChild(this.backdropElement);
        document.body.className = document.body.className.replace(/modal-open\b/, "");
    }

You have the option to engage with the modal directly:

$('#myModal').modal('toggle');
$('#myModal').modal('show');
$('#myModal').modal('hide');

Simply integrate it as provided in your methods.

Answer №3

A more efficient approach would be:

On the Template Side :

<modal  id='savemodaledits' #saveModalEdits>
.....
</modal>

<button (click)='saveModalEdits.open()'>Display Modal</button>
<button (click)='saveModalEdits.close()'>Hide Modal</button>

On the Component Side :

@ViewChild('saveModalEdits') saveModalEdits;
......
this.saveModalEdits.open();
this.saveModalEdits.close();
