Catch the id via URL in JS sent by PHP

I have a code that throws an ID in the HTML for a link:

<a href="javascript:confirmacao(<?php echo $row['idfoto'] ?>)"> <i class="fas fa-trash"></i></a>

In JavaScript I already have the code that calls the file delete.php , which takes the ID.

function confirmacao(id) {
var resposta = confirm("Tem certeza que deseja remover essa informação?");

if (resposta == true) {
    $.ajax({
        url: '/delete.php?delete_id=' + id,
        type: 'GET',
        dataType: 'json'
    }).done(function (data) {
        $.get("/read.php", {}, function (data, status) {
            $('.read_content').html(data);
        });
    });
}
}

I made a modification and created a function inside the ready of jQuery as above, which is giving this error when I click on the link.

  

VM499: 1 Uncaught ReferenceError: Confirmation is not defined       at: 1: 1   (anonymous) @ VM499: 1

You're talking about the function not defined, does it have something to do with jQuery?
