javascript - 如何创建一个启动按钮 "Bootstrap Tour"？

Question

我在我的网站“Drupal 8”上安装了下一个模块“D8:Bootstrap Tour”，它使用主题“Bootstrap 3”。

https://www.drupal.org/project/bs_tour

http://bootstraptour.com/api/

这是模块的文件 bs-tour.js 的内容:

(function ($, _, Drupal, drupalSettings) {
  'use strict';

  Drupal.behaviors.bsTour = {
    attach: function (context, settings) {
      $(window).on('load', function (event) {
        try
        {
          var tourOptions = $(drupalSettings.bs_tour.tour)[0];
          var tips = tourOptions.steps;
          var keyboard = tourOptions.keyboard;
          var debug = tourOptions.debug;
          var steps = [];

          for (var i = 0; i < tips.length; i++) {
            if ($(tips[i].element).length > 0) {
              tips[i].backdropPadding.top = parseInt(tips[i].backdropPadding.top);
              tips[i].backdropPadding.right = parseInt(tips[i].backdropPadding.right);
              tips[i].backdropPadding.bottom = parseInt(tips[i].backdropPadding.bottom);
              tips[i].backdropPadding.left = parseInt(tips[i].backdropPadding.left);

              switch (tips[i].backdrop) {
                case "0":
                  tips[i].backdrop = false;
                  break;

                case "1":
                  tips[i].backdrop = true;
                  break;
              }

              steps.push(tips[i]);
            }
          }

          if (steps.length) {
            var tour = new Tour({
              debug: debug,
              keyboard: keyboard,
              template: "<div class='popover tour'>\
              <div class='arrow'></div>\
              <h3 class='popover-title'></h3>\
              <div class='popover-content'></div>\
              <div class='popover-navigation'>\
              <button class='btn btn-default' data-role='prev'>« " + Drupal.t('Prev') + "</button>\
              <span data-role='separator'>|</span>\
              <button class='btn btn-default' data-role='next'>" + Drupal.t('Next') + " »</button>\
              <button class='btn btn-default' data-role='end'>" + Drupal.t('Skip tour') + "</button>\
              </div>\
              </div>",
            });

            // Add steps to the tour
            tour.addSteps(steps);

            // Initialize the tour
            tour.init();

            // Start the tour
            tour.start();

            // Add tour object to drupalSettings to allow manipulating tour from other modules.
            // Example: drupalSettings.bs_tour.currentTour.end();
            drupalSettings.bs_tour.currentTour = tour;
          }

        } catch (e) {
          // catch any fitvids errors
          window.console && console.warn('Bootstrap tour stopped with the following exception');
          window.console && console.error(e);
        }
      });
    }
  };

})(window.jQuery, window._, window.Drupal, window.drupalSettings);

首次访问该网站时，访问会自动开始。我的问题是，当用户单击“结束访问”时，重新启动访问的唯一方法是从浏览器中删除 cookie。该模块没有手动启动访问的按钮。

我使用以下代码在 Drupal 中创建了一个自定义 block :

<button class="btn btn-success btn-sm" data-target="#start"><i class="fa fa-compass fa-lg"></i> Commencer la visite</button>

我在子主题的 js 文件夹中创建了一个文件tour.js:

/**
 * @file
 * Bootstrap Tour.
 */

 var tourObject = drupalSettings.bs_tour.currentTour;
 if (tourObject && tourObject._options.steps.length) {
   tourObject.start();
 }

我修改了子主题的 bootstrap_subtheme_front_office.libraries.yml 文件，如下所示:

global-styling:
  css:
    theme:
      fonts/font-awesome/css/font-awesome.css: {}
#      bootstrap/dist/css/bootstrap.css: {}
#      css/bootstrap-cosmo.css: {}
      css/style.css: {}
#      css/style-noel.css: {}
#      css/style-nouvel-an.css: {}

bootstrap-scripts:
  js:
    bootstrap/js/affix.js: {}
    bootstrap/js/alert.js: {}
    bootstrap/js/button.js: {}
    bootstrap/js/carousel.js: {}
    bootstrap/js/collapse.js: {}
#    bootstrap/js/dropdown.js: {}
    bootstrap/js/modal.js: {}
    bootstrap/js/tooltip.js: {}
    bootstrap/js/popover.js: {}
    bootstrap/js/scrollspy.js: {}
    bootstrap/js/tab.js: {}
    bootstrap/js/transition.js: {}
    js/tour.js: {}

我清理了缓存，但按钮不起作用。这是我网站的页面，按钮位于左侧菜单中。

我找到了解决方案:

我将模块的文件“bs-tour.js”复制到子主题的文件夹 js 中，并在其中插入以下代码:

    $('#bs-tour-restart').click(function () {
        // Restart the tour
        tour.restart();
    });

bs-tour.js 文件现在如下所示:

(function ($, _, Drupal, drupalSettings) {
  'use strict';

  Drupal.behaviors.bsTour = {
    attach: function (context, settings) {
      $(window).on('load', function (event) {
        try
        {
          var tourOptions = $(drupalSettings.bs_tour.tour)[0];
          var tips = tourOptions.steps;
          var keyboard = tourOptions.keyboard;
          var debug = tourOptions.debug;
          var steps = [];

          for (var i = 0; i < tips.length; i++) {
            if ($(tips[i].element).length > 0) {
              tips[i].backdropPadding.top = parseInt(tips[i].backdropPadding.top);
              tips[i].backdropPadding.right = parseInt(tips[i].backdropPadding.right);
              tips[i].backdropPadding.bottom = parseInt(tips[i].backdropPadding.bottom);
              tips[i].backdropPadding.left = parseInt(tips[i].backdropPadding.left);

              switch (tips[i].backdrop) {
                case "0":
                  tips[i].backdrop = false;
                  break;

                case "1":
                  tips[i].backdrop = true;
                  break;
              }

              steps.push(tips[i]);
            }
          }

          if (steps.length) {
            var tour = new Tour({
              debug: debug,
              keyboard: keyboard,
              template: "<div class='popover tour'>\
              <div class='arrow'></div>\
              <h3 class='popover-title'></h3>\
              <div class='popover-content'></div>\
              <div class='popover-navigation'>\
              <button class='btn btn-default' data-role='prev'>« " + Drupal.t('Prev') + "</button>\
              <span data-role='separator'>|</span>\
              <button class='btn btn-default' data-role='next'>" + Drupal.t('Next') + " »</button>\
              <button class='btn btn-default' data-role='end'>" + Drupal.t('Skip tour') + "</button>\
              </div>\
              </div>",
            });

            // Add steps to the tour
            tour.addSteps(steps);

            // Initialize the tour
            tour.init();

            // Start the tour
            tour.start();

            $('#bs-tour-restart').click(function () {
                // Restart the tour
                tour.restart();
            });

            // Add tour object to drupalSettings to allow manipulating tour from other modules.
            // Example: drupalSettings.bs_tour.currentTour.end();
            drupalSettings.bs_tour.currentTour = tour;
          }

        } catch (e) {
          // catch any fitvids errors
          window.console && console.warn('Bootstrap tour stopped with the following exception');
          window.console && console.error(e);
        }
      });
    }
  };

})(window.jQuery, window._, window.Drupal, window.drupalSettings);

我使用以下代码创建了一个自定义 block :

<button class="btn btn-success btn-sm" id="bs-tour-restart"><i class="fa fa-compass fa-lg"></i> Commencer la visite</button>

我不知道这是否是一个好的做法，但是开始游览的按钮有效;-)

Answer 1

我认为你需要delete/expire首先使用一些 javascript 来处理 cookie，然后再次开始游览。

function eraseCookie(name) {   
  document.cookie = name+'=; Max-Age=-99999999;';  
}

更新:如果您收到“不是函数”错误，请尝试将代码包装在:

$(document).ready(function() { [code here] });
