删除时确认提醒

Question

我有一个表删除<a>标签。我已经可以删除数据。但是，如果用户想要真正删除它，我想要做的是发出是或否的警告。我尝试使用JavaScript，但无法使其工作。

这是我的代码

<?php 
      $action = ''; 
      if(isset($_GET['action'])) 
      $action=$_GET['action']; 
      if($action=='delete') 
      { 
       $speakerid=$_GET['speakerid']; 
       $delete = mysqli_query($conn, "DELETE FROM accounts WHERE id=$speakerid"); 
       header("Location:accountList.php"); 
      } 
     ?> 

     <?php while($row = mysqli_fetch_array($search_result)):?> 
        <tr> 
         <td><?php echo $row['firstname'];?></td> 
         <td><?php echo $row['lastname'];?></td> 
         <td><?php echo $row['emailaddress'];?></td> 
         <td><?php echo $row['contactnumber'];?></td> 
         <td><?php echo $row['status'];?></td> 
         <td><?php echo $row['date_added'];?></td> 
         <td align='center'><?php echo "<a style='padding:6px; background-color:red; color:white; border-radius: 3px;' href='accountList.php?action=delete&speakerid=".$row['id']."'>delete</a>";?></td> 
        </tr>                            
     <?php endwhile;?>

一个简单的方法来做到这将是：

<?php echo "<a style='padding:6px; background-color:red; color:white; border-radius: 3px;' href='accountList.php?action=delete&speakerid=".$row['id']."' onclick='return confirm(\"Really delete ?\");'>delete</a>";?>
