当用户单击删除按钮时，如何添加 JavaScript 警报以确认（是或否）？我尝试向警报添加一个类：

<?php
//$con = mysqli_connect("localhost", "root", "root", "db");
$sql = "SELECT * FROM `uploads` where userId = " . $_SESSION['user'];
$qry = mysqli_query($conn,$sql) or die(mysqli_error($conn));

$table_content = "";

while($row = mysqli_fetch_assoc($qry)){
    $id = $row['id'];
    $name = $row['name'];
    $table_content .= "<tr>
                         <td>
                           <a href='listen.php?id=$id' target='_new'>$name </a>
                         </td>
                         <td>
                           <a href='delete.php?id=$id' type='button' class='btn btn-danger'>delete</a>
                         </td>
                       </tr>";
}

echo "<table>".$table_content."</table>";
?>
