AJAX脚本在提要下输出新帖子，我如何移动到上面 - AJAX script outputs new posts under feed, how do i move to above?

当点击提要底部的div时，这个AJAX脚本加载更多的帖子，但是我想知道的是如何更改脚本以显示提要顶部的新帖子。不是底部。

源代码:

loadmore.php——

include('../general_scripts/connect.php');

金额很抱歉，只是不想错过任何东西。我不是要求你写任何代码，而是简单地指出我如何改变这一点，哪一部分使它在提要下面输出。不是顶部。谢谢你:D !

您需要将您的追加更改为前置。Append将其添加到底部，prepend添加到顶部。

改变

$("ol#updates").append(html);

$("ol#updates").prepend(html);
