我错过了什么？在“你确定你要删除”中的“确定”之后，我什么都没有得到。但是当我试图提醒$id时，它工作了。是 AJAX 的问题吗？
我在我的footer.php里有这个

<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>

<script>

    $(document).ready(function () {

        $('.confirm-delete').click(function (e) {
            e.preventDefault();

            confirmDialog = confirm("Are you sure you want to delete?");
            if(confirmDialog)
            {
                var id = $(this).val();
                // alert(id);
                $.ajax({
                    type: "DELETE",
                    url: "/employee/confirmdelete/"+id,
                    success: function (response) {
                        alert("Data deleted successfuly");
                       
                    }
                });
            }

        });
    });

</script>

我在我的routes.php里有这个

$route['employee/confirmdelete/(:any)']['DELETE'] = 'Frontend/EmployeeController/delete/$1';

我的删除按钮

<button type="button" class="btn btn-danger confirm-delete" value="<?= $row->id; ?> ">Confirm Delete</button>

我在控制器中的删除功能

public function delete($id)
{
    $this->load->model('EmployeeModel');
    $this->EmployeeModel->deleteEmployee($id);  
    redirect(base_url('employee'));
}

我模型删除功能

public function deleteEmployee($id)
{
    return $this->db->delete('employee', ['id' => $id]);
}"
