WordPress中搜索结果的无限滚动

Question

在窗口滚动上使用jquery加载结果的下一页，下面的代码已经可以创建无限滚动来加载自定义帖子而不是分页了，我想做的是在自定义搜索中使用相同的逻辑查询

// append load more button to send ajax request on the right moment
$('.project-listings').append('<span class="load-more"></span>');
var button = $('.project-listings .load-more'),
  page = 2,
  loading = false,
  scrollHandling = {
    allow: true,
    reallow: function() {
      scrollHandling.allow = true;
    },
    delay: 400
  };
$(window).scroll(function() {
  if (!loading && scrollHandling.allow) {
    scrollHandling.allow = false;
    setTimeout(scrollHandling.reallow, scrollHandling.delay);
    var offset = $(button).offset().top - $(window).scrollTop();
    if (2000 > offset) {
      loading = true;
      $('.loader-wrap').css({
        display: 'flex'
      });
      var data = {
        'action': 'projects_search_results',
        'page': page,
        'region': AJAX.region,
        'search_text': AJAX.search_text,
      };
      // console.log(data);
      $.post(AJAX.ajaxurl, data, function(response) {
        if (response.data != "") {
          $('.project-listings .content-wrap').append(response.data);
          $('.project-listings').append(button);
          page++;
          $('.loader-wrap').css({
            display: 'none'
          });

          });
          scrollHandling.allow = false;

// Initialize query prams

    }


    if ( !empty( $_POST['search_text'] ) && $_POST['search_text'] != null ) {
        $args['s'] = $_GET['s'];
    }
    // start buffer 
    ob_start();

    if ( $query->have_posts() ) :
        while($query->have_posts()){ $query->the_post();
            get_template_part("template-parts/projects");
        }
