我有一个客户模型,具有以下内容_form.html.erb partial:

<%= 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,分配了类“selectpicker”的字段将拾取bootstrap select rails gem格式的选择字段,并应用bootstrap select rails select的更新外观,这是正确的行为。但是,如果我在客户模型页面中的任意位置选择一个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bootstrap select字段

如果再次使用浏览器按钮重新加载页面,则会正确加载增强的选择字段


问题是,我安装了turbolinks和jQuery.turbolinks,并且application.js清单文件以正确的顺序加载了所有正确的引用。我不明白为什么jQuery.turbolinks没有自动处理页面加载和页面更改上的javascript加载?它似乎只在初始页面加载或浏览器刷新时工作,任何rails页面更改都不会重新加载javascript。

我不知道您是否找到了解决问题的方法。我在目前正在进行的一个项目中遇到了同样的问题,我发现在我的javascript控制器文件中添加此代码似乎可以解决这个问题:

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

这解决了我的问题:

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

参考资料:

您可能正在使用咖啡编写脚本,因此您可以编写以下内容:

(($) ->
  $(document).on 'page:change', ->
    $('.dropdown-toggle').dropdown()
    $('.selectpicker').selectpicker()
) jQuery

另一种方法可以是:

$('.selectpicker').selectpicker('refresh');
从文档中:

要使用JavaScript以编程方式更新select,请首先操作select,然后使用refresh方法更新UI以匹配新状态。当删除或添加选项,或通过JavaScript禁用/启用select时,这是必需的
