这是我的光滑滑块：

            var informations_panel = document.querySelector("#block-views-block-wazne-informacje-strona-glowna-block-1 > div:nth-child(3) > div > div.view-content");
            $(informations_panel).slick({
                autoplay: true,
                autoplaySpeed: 5000,
                arrows: true,
                dots: true,
                infinite: true,
                slidesToShow: 2,
                slidesToScroll: 1
            });

当用户调整窗口大小时，有没有办法更改slidesToShow属性？使用 $(window).resize()，类似：

    $(window).resize(function(){
        var informations_panel = document.querySelector("#block-views-block-wazne-informacje-strona-glowna-block-1 > div:nth-child(3) > div > div.view-content");
        if ($(window).width() < 992) {
            $(informations_panel).slick({
                autoplay: true,
                autoplaySpeed: 5000,
                arrows: true,
                dots: true,
                infinite: true,
                slidesToShow: 1,
                slidesToScroll: 1
            });
        }
    });

该解决方案出现错误，我无法再次在同一元素上初始化光滑。我只想slidesToShow当窗口宽度大于 992px 时将属性从 2 更改为 1。

我知道在 stackoverflow 上有很多与此错误类似的问题，但没有一个能解决我的问题。我的文件中有一个函数high_contrast.module：

function high_contrast_install() {
  $background = \Drupal::config('high_contrast.settings')->get('colors_background');
  $text = \Drupal::config('high_contrast.settings')->get('colors_text');
  $hyperlinks = \Drupal::config('high_contrast.settings')->get('colors_hyperlinks');

  \Drupal::service('file_system')->prepareDirectory(HIGH_CONTRAST_CSS_FOLDER, FileSystemInterface::CREATE_DIRECTORY); // LINE 17!!!
  $css = _high_contrast_build_css();
  file_save_data($css, HIGH_CONTRAST_CSS_LOCATION, FileSystemInterface::EXISTS_REPLACE);
}

当我想安装该模块时，出现错误：

Error: Cannot pass parameter 1 by reference in high_contrast_install() (line 17 of modules\high_contrast\high_contrast.install).

我该如何修复它？:(

第 17 行就是：

  \Drupal::service('file_system')->prepareDirectory(HIGH_CONTRAST_CSS_FOLDER, FileSystemInterface::CREATE_DIRECTORY);
