How to show a confirm message before delete?

Question

Write this in onclick event of the button:

var result = confirm("Want to delete?");
if (result) {
    //Logic to delete the item
}

You can better use as follows

 <a href="url_to_delete" onclick="return confirm('Are you sure you want to delete this item?');">Delete</a>

This is how you would do it with unobtrusive JavaScript and the confirm message being hold in the HTML.

<a href="/delete" class="delete" data-confirm="Are you sure to delete this item?">Delete</a>

This is pure vanilla JS, compatible with IE 9+:

var deleteLinks = document.querySelectorAll('.delete');

for (var i = 0; i < deleteLinks.length; i++) {
  deleteLinks[i].addEventListener('click', function(event) {
      event.preventDefault();

      var choice = confirm(this.getAttribute('data-confirm'));

      if (choice) {
        window.location.href = this.getAttribute('href');
      }
  });
}

function ConfirmDelete()
{
  return confirm("Are you sure you want to delete?");
}


<input type="button" onclick="ConfirmDelete()">

it is very simple and one line of code

<a href="#" title="delete" class="delete" onclick="return confirm('Are you sure you want to delete this item')">Delete</a>

Try this. It works for me

 <a href="delete_methode_link" onclick="return confirm('Are you sure you want to Remove?');">Remove</a>
