jQuery“加载更多帖子”如果最后发布则隐藏按钮

Question

I am using jQuery to create a "load more posts" effect for the Wordpress loop. Since the loop has all the posts already loaded and they just appear with jQuery I have not been able to hide the "load more" button when I reach the last one.

$(document).ready(function () {
$(".post").addClass("hide"); 
total = $("#allpost .post").size();
x = 3;

    $('.loadmore').click(function () {
       //y = x;
        $(total);
    $(".post").removeClass("hide");     
        $(".post:gt("+x+")").addClass("hide"); 
     x = x + 1;
    });
});

My loop

<div id="all-posts">
        <?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; 
        $args= array(
    'posts_per_page' => 100,
    'paged' => $paged
);
query_posts($args); ?> <!-- posts per page -->
        <?php if (have_posts()) : while (have_posts()) : the_post(); ?>
        <?php $postcount++;
$new_class = ( ($postcount % 2) == 0 ) ? "even" : "odd"; ?>
<div <?php post_class($new_class) ?> id="post-<?php the_ID(); ?>">
    <div class="post_image">
        <a href="<?php echo the_permalink(); ?>">
        <?php if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
            the_post_thumbnail('custom-size'); // post thumbnail    
        }?>
        <button class="blog_button">Vaata</button></a>
    </div>
    <div class="post_tekst">
        <div class="lisakast">
            <h2><?php the_title(); ?></h2>
            <p><?php the_excerpt(); ?></p>
        </div>
    </div>  
    </div><!-- odd / even div -->
        <?php endwhile; endif; ?>
              <div class="loadmore">Lae juurde</div>
        </div><!-- all posts -->

How could this be achieved?

Answer 1

You only need to add an extra validation at your JS code.

$(document).ready(function () {
    $(".post").addClass("hide"); 
    total = $( ".post" ).length;
        x = 3;

    $('.loadmore').click(function () {
       //y = x;
        $(total);
    $(".post").removeClass("hide");     
        $(".post:gt("+x+")").addClass("hide"); 
     x++;


    if($(".post.hide").length == 0){
        $('.loadmore').addClass('hide');
    }

    });

When all posts are visible, then hide the "load more" button

Answer 2

You can use the following code:

$(document).ready(function () {
    $(".post").addClass("hide"); 
        total = $( ".post" ).length;
            x = 3;

        $('.loadmore').click(function () {
           //y = x;
            $(total);
        $(".post").removeClass("hide");     
            $(".post:gt("+x+")").addClass("hide"); 
         x++;


        if(x >= total){
        $( ".loadmore" ).hide();
        }

        });

    });

.length() function:

The number of elements currently matched. The .size() method will return the same value. To get more information about .length() : Click
