用ajax分页

Question

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...

Answer 1

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

if ($num_rows < 6){
  //remove more button
}
