javascript - 弹出确认删除php

问题描述

所以我的代码在下面，它从 dmgeqdelete.php 读取，它将立即从数据库中删除数据。<td align="center"> <a href="dmgeqdelete.php?damagedID=<?php echo $row["damagedID"]; ?>" >Delete</a> </td>

我正在尝试为上述代码添加弹出确认。我试过<td align="center"> <a href="dmgeqdelete.php?damagedID=<?php echo $row["damagedID"]; ?>" onclick="return confirm('Are you sure?')">Delete</a> </td>没有采取任何行动

dmgeqdelete.php

<?php
include('dbConfig.php');
$damagedID=$_REQUEST['damagedID'];
$query = "DELETE FROM damagedeq WHERE damagedID=$damagedID"; 
$result = mysqli_query($conn,$query) or die ( mysqli_error());
header("Location: dmgeqview.php"); 
?>

完整代码

<?php
include('dbConfig.php');
?>

解决方案

这里只需要停止代码的进一步执行

onclick="return confirm('Are you sure?')"

return false像这样在最后添加

onclick="return confirm('Are you sure?'); return false;"

单击取消时不会发生任何事情，但如果单击确定，它将转到链接
