当单击提要底部的 div 时，此 AJAX 脚本会加载更多帖子，但我想知道如何更改脚本以在提要顶部显示新帖子......而不是底部。
源代码:
loadmore.php-
<?php
include('../general_scripts/connect.php');
?>

$(function() {
//More Button
$('.more').live("click",function()
{
var ID = $(this).attr("id");
if(ID)
{
$("#more"+ID).html('<img src="moreajax.gif" />');
$.ajax({
type: "POST",
url: "ajax_more.php",
data: "lastmsg="+ ID,
cache: false,
success: function(html){
$("ol#updates").append(html);
$("#more"+ID).remove();
}
});
}
else
{
$(".morebox").html('no more to display.');
}
return false;
});
});
</script>

抱歉，金额有限，只是不想错过任何事情。 我并不是要求您编写任何代码，而是简单地指出我如何更改此设置以及哪个部分使其输出在提要下方......而不是顶部。谢谢:D!
最佳答案
您需要将追加更改为前置。追加将其添加到底部，添加到顶部。
改变
$("ol#updates").append(html);
至
$("ol#updates").prepend(html);
关于php - AJAX 脚本在 feed 下输出新帖子，我如何移动到上面？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5614759/
