我有这个代码
// If there is no data returned, there are no more posts to be shown. Show error
if(data == "") {
$this.find('.loading-bar').html($settings.error);
} else {
// Offset increases
offset = offset+$settings.nop;
// Append the data to the content div
$this.find('#content_ins_con_all_posts').append(data);
// No longer busy!
busy = false;
}
此代码在点击底部时向我显示一条消息，并且没有其他帖子可显示。我的问题是，当我继续滚动时，消息会一次又一次地多次显示...我只想在帖子结束时向我显示一次消息。如果有办法我可以做到这一点，这是非常受欢迎的。

delay : 2000, // When you scroll down the posts will load after a delayed amount of time.
