blocks|key|3178688|text|您可以设置一个全局Javascript变量，以保存总发帖量，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3178689|var+total+=+<?php+echo+$total+?>;|code-block|syntax|javascript|3178690|呼叫结束后，将金额与总数进行比较：|3178691|if($('.post').length+==+total)+//+.post+being+database+results

You could set a global Javascript variable holding the amount of total posts something like this:

<pre><code>var total = &lt;?php echo $total ?&gt;;
</code></pre>

And after the call compare the amount to the total:

<pre><code>if($('.post').length == total) // .post being database results
 $('#loadmore').hide();
</code></pre>

blocks|key|3178712|text|你可以试试这样的东西|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3178713|if+($num_rows+<+5){

at the end of you loop

blocks|key|3193345|text|很简单。选择6个帖子而不是5个，然后只显示5。如果没有少于6的帖子，不要显示更多的按钮。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3193346|if+($num_rows+<+6){

simple. select 6 posts instead of 5 and display only 5.If no of posts less than 6 dont display more button.

<pre><code>if ($num_rows &lt; 6){
 //remove more button
} 
</code></pre>

blocks|key|3178801|text|请，请，请-不要在Ajax中分页！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3178802|这是痛苦的在$$导航这样的网页自然的方式，不能使用后退按钮或重新加载按钮或设置一个标志或任何东西！|3178803|更不用说根本不支持js的客户端了|3178804|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

<h1>Please, please, please - do not do pagination in Ajax!</h1>

It is pain in the a$$ to navigate such pages natural way, unable to use back button or reload button or set a bokmark or anything!

not to mention clients that doesn't support js at all

blocks|key|3178818|text|返回一个JSON对象，其中一个属性是数组(条目)，另一个属性是bool+"EOF“之类的属性，以指示何时没有更多的条目要加载。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3178819|如果(response.EOF)//隐藏按钮。|3178820|在AjaxRequest中添加来自当前分页的最后一篇文章的id。那样的话，服务器就会给你比如说它给你的上一篇文章的25个帖子。然后，如果在分页过程中添加了新的帖子，则不会得到偏移。|3178821|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

Return a JSON object with one property that is an array (the entries) and one property that is a bool "EOF" or such to indicate when there is no more entries to load.

if(response.EOF)
//Hide button..

Ohh and add the id of the last post from current pagination in the AjaxRequest.
That way the server gives you say 25 posts from the last one it gave you.
Then you dont get offsets if a new post is added during pagination.

I've build an application (with PHP, Codeigniter and jQuery) that uses ajax for pagination, similar to how Twitter made it back in the day (clicking a button to load in more data).

It's all quite well, but there are a few issues however.

When there are no more posts left to load in, I want the "load-more"-button to be removed. However, right now I can only check if there are any posts left when I click the button, and the script returns null. 

This is how it is now: Let's say that there are 14 posts in the database. 5 is loaded per default.

1 - click load-more, 5 more posts are loaded. 4 remain.

2 - click load-more, the remaining 4 posts are loaded.

3 - click load-more, no more remaining posts, button disappears

But I want to get rid of step 3, the application should "be aware" of that there are no more posts left to render at step 2.

I am sure there are a simple way that I haven't thought if yet...

我已经构建了一个应用程序(使用PHP、Codeigniter和jQuery)，该应用程序使用ajax进行分页，类似于Twitter在当天的应用程序(单击按钮加载更多数据)。这一切都很好，但也有一些问题。当没有更多的帖子需要加载时，我希望删除“load -更多”-button。但是，现在我只能在单击按钮时检查是否还有帖子...
