使用分页进行Wordpress延迟加载

Question

即时通讯使用WP_Query分页进行延迟加载，它工作正常，但内容到达终点时会重复自身，当我搜索特定结果时，它会正确显示结果，但是在此之后，它仍然想要进行延迟加载，因此它将加载随机数据

这是我的代码

懒加载

    <?php 

add_action('wp_ajax_nopriv_load_posts_by_ajax', 'load_posts_by_ajax_callback');
add_action('wp_ajax_load_posts_by_ajax', 'load_posts_by_ajax_callback');

function load_posts_by_ajax_callback(){
    // check_ajax_referer( 'load_more_posts', 'security' );
    $paged = $_POST['page'];
    $args = array(
        'post_type' => 'unit',
        'post_status' => 'publish',
        'posts_per_page' => 4,
        'paged' => $paged
    );
    if ( !empty($_POST['taxonomy']) &&  !empty($_POST['term_id']) ){
        $args['tax_query'] = array (
            array(
                'taxonomy' => $_POST['taxonomy'],

        while($query->have_posts()){ $query->the_post(); 
            get_template_part("template-parts/units"); 
        } 
    endif; wp_reset_postdata();
    // start buffered data in data variable
    $data = ob_get_clean();
    wp_send_json_success( $data );
    wp_die();

                'field'    => 'slug',
                'terms'    => $_POST['ptype'],
            ),
        );
    }
    if ( !empty($_POST['taxonomy']) &&  !empty($_POST['term_id']) ){

    // start buffered data in data variable

    wp_send_json_success( $data );
    wp_die();
}

懒加载

    $('.unit-terms li a').each( function() {
    if ( this.href == window.location.href ) {
        $(this).parent().addClass('current');
    }
});

main.js

    (function($){
  $('.isotope a').on('click', function(){
    $('.isotope .active').removeClass('active');
    $(this).addClass('active');
    var filter = $(this).data('filter');
    if(filter=='*'){
    $('.property').show();
  }else{
    $('.property').not(filter).hide();
    $('.property'+filter).show();
  }
  return false;
  });
})(jQuery);

所以我该如何运作呢？我不知道我在做什么错
