Error message

Thank you for I want to delete myself and my parent by pressing button using vue
I wanted to apply it, but it doesn't work.

Applicable source code

// In the beginning, the following div elements are hidden
 
   <button @ click = "deleteDom">Delete</button>
 
<button @ click = "addDom">Increase</button>

Press the button to increase

 
   <button @ click = "deleteDom">Delete</button>
 
 
   <button @ click = "deleteDom">Delete</button>
 
 
   <button @ click = "deleteDom">Delete</button>
 
 
   <button @ click = "deleteDom">Delete</button>
 
<Button @ click = "addDom">Increase</button>

And remove class = "dispNone" and duplicate or press the delete button (@ click = "deleteDom)


   <Button @ click = "deleteDom">Delete</button>
 
<Button @ click = "addDom">Increase</button>

Or delete like

. dispNone {
  display: none;
}

window.Vue = require ('vue');
const app = new Vue ({
    el: '#app',
    data: {},
    methods: {
AddDom: function () {
          // I want to draw a method for the button to remove the class here and increase it, but I'm not sure.
        }
      deleteDom: function (e) {// For deletion. I have diverted something that was referred to in previous questions.
            var del = e.target.parentNode;
            del.parentNode.removeChild (del);
        }
    }
