意识到这个问题(或其风格)已经被广泛记录，但尽管我进行了调查和阅读，我仍然无法解决这个问题，因为......

我的 application.js list 如下:

//= require jquery
//= require jquery.turbolinks
//= require jquery_ujs
//= require_self
//= require_tree .
//= require bootstrap-sprockets
//= require data-confirm-modal
//= require allPages

//= require dataTables/bootstrap/3/jquery.dataTables.bootstrap
//= require jquery_nested_form
//= require bootstrap-select
//= require bootstrap/alert
//= require bootstrap/dropdown
//= require turbolinks

我有一个包含以下 _form.html.erb 部分的客户模型:

<%= simple_form_for(@customer, html: { class: 'form-horizontal' },
  wrapper: :horizontal_form,
  wrapper_mappings: {
    check_boxes: :horizontal_radio_and_checkboxes,
    radio_buttons: :horizontal_radio_and_checkboxes,
    file: :horizontal_file_input,
    boolean: :horizontal_boolean
 }) do |f| %>
<%= f.error_notification %>
<fieldset>
  <div class="form-inputs">
    <%= f.input :code, required: true %>
    <%= f.input :name, required: true %>
    <%= f.input :location, required: true, 
                    :collection => LookupValue.joins(:lookup).where(lookups: { :name => 'Location' }).order(name: :asc).pluck(:name), 
                    :include_blank => false, 
                    input_html: { class: 'selectpicker' } %>
        <%= f.input :service_level, 
                    :collection => LookupValue.joins(:lookup).where(lookups: { :name => 'Service level' }).order(name: :asc).pluck(:name), 
                    :include_blank => false,
                    input_html: { class: 'selectpicker' } %>
        <%= f.input :golive_date, :as => :date_picker %>
        <%= f.input :connection_type, 
                    :collection => LookupValue.joins(:lookup).where(lookups: { :name => 'Connection type' }).order(name: :asc).pluck(:name), 
                    :include_blank => false,
                    input_html: { class: 'selectpicker' } %>
        <%= f.input :service_centre, 
                    :collection => LookupValue.joins(:lookup).where(lookups: { :name => 'Service centre' }).order(name: :asc).pluck(:name), 
                    :include_blank => false,
                    input_html: { class: 'selectpicker' } %>
        <%= f.input :end_date, :as => :date_picker %>
        <%= f.input :sla, 
                    :collection => LookupValue.joins(:lookup).where(lookups: { :name => 'SLA' }).order(name: :asc).pluck(:name), 
                    :include_blank => false,
                    input_html: { class: 'selectpicker' } %>
        <%= f.input :project_code %>
      </div>

  <div class="form-actions">
     <%= f.button :submit, :class => "btn btn-primary" %>
  </div>
</fieldset>
<% end %>

我的 customer.js.coffee 脚本文件是:

# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://coffeescript.org/

jQuery ->
  $('#customers').dataTable
    sPaginationType: "full_numbers"
    bProcessing: true
    bServerSide: true
    sAjaxSource: $('#customers').data('source')
    iDisplayLength: 200
    oLanguage:
      sLengthMenu: "Display <select>" + "<option value=\"50\">50</option>" + "<option value=\"100\">100</option>" + "<option value=\"300\">300</option>" + "<option value=\"-1\">All</option>" + "</select> records"

  $(".selectpicker").selectpicker

当我直接加载客户编辑页面或使用浏览器刷新按钮刷新页面时，分配有“selectpicker”类的字段将拾取 bootstrap-select-rails gem 格式的选择字段并应用更新的外观和bootstrap-select-rails select 的感觉(这是正确的行为)。但是，如果我在客户模型页面中的任何位置选择一个 Rails 链接，然后返回到客户编辑页面，则表单呈现时不会显示 bootstrap-select-rails gem 中的增强选择字段，而是显示正常的默认引导选择字段。

如果我再次使用浏览器按钮重新加载页面，增强的选择字段将正确加载。

问题是我安装了turbolinks和jQuery.turbolinks，并且application.js list 文件以正确的顺序加载了所有正确的引用，我很困惑为什么jquery.turbolinks不处理javascript的加载页面加载和页面更改都会自动进行吗？它似乎只在初始页面加载(或浏览器刷新)时起作用，并且任何 Rails 页面更改都不会重新加载 JavaScript。

不知道您是否找到了解决问题的方法。我在当前正在处理的项目中遇到了同样的问题，我发现在我的 javascript Controller 文件中添加此代码似乎可以解决问题:

$(document).on('page:load', function(){
    $('.selectpicker').selectpicker();
});
