身份证件 变量行=$（this.parent（）.parent（）；//检索父行，以便在不重新加载整个页面的情况下删除它 var info=\'id\u app=\'+id\u app+\'&id\u user=\'+id\u user； $.ajax({ 类型：“POST”， url:“./functions/del_app.php”， 数据：信息， 成功：函数（）{ $（行）.remove（）；//删除行 } }); } });

删除完成后，请注意，您可以删除该行，而不是重新加载整个页面。

根据我自己的经验，我将执行以下操作：

<?php
$user=$_SESSION['userid'];
$con = db_connect();

$result = $con->query("SELECT  `id_app`, `date_cr`,`id_user`
                        FROM `applications`
                        WHERE id_user = $user");
?>

<?php if(($data = $result->num_rows)==0){ ?>

    <p class="error">No data</p>                

<?php } else { ?>           
    <script type="text/javascript" src="./functions/jquery-1.7.1.min.js"></script>';   
    <br/>
    <br/>
    <table id="tab_history">
        <tr>
            <td>Time when created
            <td>
        </tr>

    <?php while(($data = $result->fetch_assoc())!==null) { ?>
        <tr>
            <td><?=$data['date_cr'] ?>
            <td><button class="btnDel" data-id-app="<?=$data['id_app'] ?>" data-id-user="<?=$data['id_user'] ?>" type="button">
        Delete</button>
        </tr>

    <?php } ?>
    </table>
<?php } ?>
<script>
$(".btnDel").click(function (e) { 
            e.preventDefault();

            if (confirm(\'Are you sure?\')){
                var id_app = $(this).attr('data-id-app');
                var id_user = $(this).attr('data-id-user');

                $.ajax({
                   type: "POST",
                   url: "./functions/del_app.php",
                   data: {
                            id_app: id_app,
                            id_user: id_user
                         },
                   success: function(){                             
                    location.reload();                          
                   }   
                });                                         
            }                     
});         
</script>
