要在Ajax调用中启用分页，需要对代码进行一些修改。主要思想是从URL参数中捕获当前页面并将其传递给WP_Query。此外，您需要在Ajax响应中返回分页HTML。

让我们相应地修改你的load_trailers函数和trailersuche函数：
load_trailers函数：

function load_trailers() {
  var newParams = window.location.search;
  if (currentParams !== newParams) {
    currentParams = newParams;
    jQuery('.products-wrapper').addClass('loading');
    jQuery.ajax({
      url: wpAjax.ajax_url,
      data: {
        action: 'trailer',
        parameter: newParams,
        query: wpAjax.query,
        page: getCurrentPageNumber(), // Add the current page number to the Ajax request
      },
      type: 'post',
    }).done(function (data) {
      jQuery('.woocommerce-archive-wrapper').empty();
      jQuery('.woocommerce-archive-wrapper').append(data.content); // Use 'content' key from the Ajax response
      jQuery('.products-wrapper').removeClass('loading');
      jQuery('.pagination').html(data.pagination); // Add this line to update the pagination
    });
  }
}

// Helper function to get the current page number from the URL
function getCurrentPageNumber() {
  var urlParams = new URLSearchParams(window.location.search);
  return urlParams.get('page') || '1';
}

trailersuche功能：

add_action('wp_ajax_trailer', 'trailersuche');
add_action('wp_ajax_nopriv_trailer', 'trailersuche');
function trailersuche()
{
  $meta_query = $_POST['query'];
  $parameters = $_POST['parameter'];
  $parameters = str_replace('?', '', explode('&', $parameters));

  // Extract page number from the Ajax request
  $paged = isset($_POST['page']) ? $_POST['page'] : 1;

  // Add 'paged' parameter to the WP_Query
  $meta_query['paged'] = $paged;

  echo '<div class="woocommerce-notices-wrapper"></div>';

  $loop = new WP_Query($meta_query);

  ob_start();

  echo '<p class="woocommerce-result-count">' . $loop->found_posts . ' Produkte</p>';
  do_action('woocommerce_before_shop_loop');
  woocommerce_product_loop_start();
  while ($loop->have_posts()) {
    $loop->the_post();
    wc_get_template_part('content', 'product');
  }
  woocommerce_product_loop_end();
  do_action('woocommerce_after_shop_loop');

  $content = ob_get_clean();

  // Return the content and pagination HTML
  $response = array(
    'content' => $content,
    'pagination' => get_the_posts_pagination(array('query' => $loop)),
  );

  wp_send_json($response);
}

这些更改应该会在加载了Ajax的产品中启用分页。确保您有一个分页容器，其中包含您希望分页链接显示的'pagination'类。
