WordPress網站上的無限滾動

Question

我有一個顯示帖子（酒店）的wordpress頁面，當前該頁面僅顯示所有酒店，但是當用戶向下滾動頁面時，我現在試圖編寫一些jQuery腳本以無限滾動方式顯示酒店。

目前，我有下面的方法，但確實可以，但是我不確定從wordpress獲取所需數據的最佳方法，以便jQuery可以正確顯示酒店。

<?php get_header(); ?>

<?php
$offset = 2;

$destination_slug = get_query_var('destination');
$term = get_term_by('slug', $destination_slug, 'destination');
$hotels = get_posts(array(
    'post_type' => 'hotels',
    'posts_per_page' => $offset,
    'tax_query' => array(
        array(
            'taxonomy' => 'destination',
            'field' => 'term_id',
            'terms' => $term->term_id
        )
    ))
);

$completeList = get_posts(array(
    'post_type' => 'hotels',
    'tax_query' => array(
        array(
            'taxonomy' => 'destination',
            'field' => 'term_id',
            'terms' => $term->term_id
        )
    ))
);

?>


<div class="pure-g">
    <div class="page-content">
       <?php the_field('hotel_description',$term); ?> 
    </div>
</div>

<div class="hotel-listing">
<?php if ( $hotels ) {
    foreach ( $hotels as $post ) :
        setup_postdata( $post ); ?>

            <div class="row pure-g nopadding member">

    $(window).scroll(function() {

                $( ".hotel-listing" ).append(html );

                offset++;
            }
        }
    }); 
</script>
</div>

<?php get_footer(); ?>

否則，將是做我想做的正確方法嗎？
