Question

我想在用户想要删除时发出确认消息
选项1 ：如果是，则从数据库中删除学生，并将用户重定向到 index.php

选项2：如果不是，则应将用户重定向到show.php

我试过了，但是我无法满足选项2的要求这是我的代码：

<body>
<center><h1>Delete record</h1></center>
<center><form action="del.php" method="post" onsubmit="return confirm('Are you sure you want to delete?')">
Enter the ID for student you want to delete :
</br><input type="text" name="id"/>        </br>
</br>
<input id="button" type="submit" value="Delete" style="width: 219px"/> </br>
<a href = "change.html">Back</a>


</form></center>
</body>

更新：

我找到了解决方案。对于任何寻求它的人。谢谢你的时间

Answer 1

<script type="text/javascript">
function areyousure(id)
{
    jConfirm("Are you sure you want to delete?", "Delete Message", function (callback) {
        if (callback) {
           window.location='delete_student.php?id='+id;
        } else {
            return false;
        }
    });
}
