当您调用
$.ajax()
调用$('.delete_按钮')
时,您不应该在那里调用loadList()
函数,因为这是重新加载表的功能,而应该从表中删除一个条目
也许您可以使用类似的方法将其删除,将其放置在delete button success回调中:
$.ajax({
type: "POST",
url: "delete.php",
data: "id="+ id,
success: function()
{
$(this).parent().parent().remove();
}
});
最终代码是
<?php
include('connection.php');
if(isset($_REQUEST["id"]))
{
$cmd=mysql_query("delete from login where id=" .$_REQUEST["id"] .";");
echo '1';
} else {
echo '0';
}
exit;
?>
此代码中存在安全漏洞。
标题(位置…
重定向页面提交时希望页面发生什么?是否希望它重新加载表(以显示记录已被删除)?现在出现了什么问题,整个页面正在重新加载?您的a.delete_按钮上仍然有href
属性。看起来您的单击事件正在通过ajax调用触发以删除记录,然后使用delete.php?id=“.$row['id']”进行刷新(&type=delete
调用。我可能错了,但如果我删除标题(位置…),我会尝试将其更改为href='#'
@HugoDozois然后页面被发送到delete.php我想在单击delete链接时删除特定行,但重新加载整个表,然后显示更改。您能建议如何执行吗?我尝试了您的解决方案,当我单击delete时,它会将我带到delete.php并显示1它不会停留在comment.php页面上,如果我从href标记中删除delete.php,它会显示不行
