Javascript 推送到数据层中未出现的数据层

我有一门活动课

/** Class representing a Google Analytics Event. */
class AnalyticsEventInterface {
  event = {};

  getEvent() {
    return this.event;
  }
}

class SearchClickEvent extends AnalyticsEventInterface {
  /**
   * Create a SearchResultClick analytics event.
   * @param {string} term - The search result's landing query term.
   * @param {string} type - The type of search result's landing with.
   * @param {int} page - The page number of the result clicked.
   * @param {int} position - The calculated position of the result clicked.
   */
  constructor(term, type, page, position) {
    super();
    this.event.event = 'search_result_click';
    this.event.search_term = term;
    this.event.search_type = type;
    this.event.search_page = page;
    this.event.search_position = position;
  }
}

以及扩展events类的特定事件

/** Class representing a Google Analytics Event. */
class AnalyticsEventInterface {
  event = {};

  getEvent() {
    return this.event;
  }
}

class SearchClickEvent extends AnalyticsEventInterface {
  /**
   * Create a SearchResultClick analytics event.
   * @param {string} term - The search result's landing query term.
   * @param {string} type - The type of search result's landing with.
   * @param {int} page - The page number of the result clicked.
   * @param {int} position - The calculated position of the result clicked.
   */
  constructor(term, type, page, position) {
    super();
    this.event.event = 'search_result_click';
    this.event.search_term = term;
    this.event.search_type = type;
    this.event.search_page = page;
    this.event.search_position = position;
  }
}

当单击事件发生时触发

(function ($) {
  'use strict';
  Drupal.behaviors.search_landing_page = function (context) {
    //When a search result is clicked a google analytics event is triggered and data collected.
    var logSearchClick = function (event) {
      var analyticsSettings = null;
      if (typeof Drupal !== "undefined" && typeof Drupal.settings !== "undefined" && typeof Drupal.settings.analytics !== "undefined") {
        analyticsSettings = Drupal.settings.analytics;
      }
      if (analyticsSettings === null) {
        // Escape early if we don't have the info that we need.
        return;
      }
      var queryTerm = analyticsSettings.term || null;
      var searchType = analyticsSettings.type || null;
      var pageNumber = analyticsSettings.page || null;
      var $results = $('.c-search-result');
      var resultsPerPage = $results.length;
      var positionData = $results.data('position');
      var positionID = positionData + ((pageNumber - 1) * resultsPerPage);
      var searchClickEvent = new SearchClickEvent(queryTerm, searchType, pageNumber, positionID);
      window.dataLayer = window.dataLayer || [];
      window.dataLayer.push(searchClickEvent.getEvent())
    }

    // Attach the function to the event.
    $('.c-search-result').off('click').on('click', logSearchClick);
  };
})(jQuery);

通过调试，所有的行都被调用，事件看起来像是被推送的，但是当我在控制台中单击搜索结果后检查数据层时，新事件不在数据层中。任何帮助都将不胜感激。我也没有访问客户端GTM的权限。

您能分享一下“searchClickEvent.getEvent（）”函数返回的控制台吗？searchClickEvent.getEvent（）；我获取未捕获的引用错误：未定义searchClickEvent和dataLayer.push（{'event'：'event'}）；我没有定义，但是我可以在调试器中跟随代码
