wp posts ajax load more

I tried to load more posts using ajax. I see there is lot of plugins and solutions in online and stackoverflow. But none of work for me. Actually I want to do this without plugin. So I can use this in different page archive or different page template where I need this code.

Here is my code that I got from another question in stackoverflow. My score is lower, so I can't comment out there.

Here is my index.php code:

<?php get_header(); ?>

<div class="ajax-posts">
<?php 
    $postsPerPage = 3;
    $args = array(
        'post_type' => 'post',
        'posts_per_page' => $postsPerPage,
    );
    $loop = new WP_Query($args);

    while ($loop->have_posts()) : $loop->the_post();
?>
<h2><?php the_title(); ?></h2>
<?php
    endwhile; 
    echo '<a id="more_posts" href="#">Load More</a>';
    wp_reset_postdata(); 
?>
</div>
<script type="text/javascript">
    var ajaxUrl = "<?php echo admin_url('admin-ajax.php')?>";
    var page = 1;.
    var ppp = 3;

    $("#more_posts").on("click",function(){ 
        $("#more_posts").attr("disabled",true);
        $.post(ajaxUrl, {
            action:"more_post_ajax",
            offset: (page * ppp) + 1,
            ppp: ppp
        }).success(function(posts){
            page++;
            $(".ajax-posts").append(posts); // CHANGE THIS!
            $("#more_posts").attr("disabled",false);
        });

   });

</script>
<?php get_footer(); ?>

Here is functions.php code

<?php 
function more_post_ajax(){
    $offset = $_POST["offset"];
    $ppp = $_POST["ppp"];
    header("Content-Type: text/html");

    $args = array(
        'post_type' => 'post',
        'posts_per_page' => $ppp,
        'offset' => $offset,
    );

    $loop = new WP_Query($args);
    while ($loop->have_posts()) { $loop->the_post();
       the_title();
    }
    exit; 
}

add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax'); 
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');
?>

I don't know why posts not load or not work load more link. I hope someone will be help.

The better way is to return an array with ur post title. Then display them after the success. If the array length < ppp (there is no more post).

$array_return = array();
$loop = new WP_Query($args);
while ($loop->have_posts()) { $loop->the_post();
$content = "<h1>" . get_the_title() . "</h1>";
$content .= "<div>" . get_the_content() . "</div>";
$content .= "<div>" . get_field("your_field") . "</div>";
$array_return[] = $content;
}
echo json_encode( $array_return );
die();

In your js script,

var posts = JSON.parse(posts);
for( var i = 0; i < posts.length; i++ )
    $(".ajax-posts").append(posts[i]);

if( posts.length < ur_ppp )
    $("#more_posts").fadeOut();

Something like that
