我的application.js清单如下:

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

//= require jquery_nested_form
//= require bootstrap-select
//= require bootstrap/alert
//= require bootstrap/dropdown

我有一个客户模型,其中包含以下_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,会出现具有类&#39; selectpicker&#39;的字段。分配给它获取bootstrap-select-rails gem格式化的select字段并应用bootstrap-select-rails选择的更新外观(这是正确的行为)。但是,如果我在客户模型页面中的任何位置选择rails链接,然后返回到客户编辑页面,则表单将显示而不使用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,则会正确加载增强的选择字段。

问题我已经安装了turbolinks和jQuery.turbolinks,并且application.js清单文件已经按照正确的顺序加载了所有正确的引用我很困惑为什么jquery.turbolinks不处理加载页面加载和页面自动更改javascript?它似乎只是在初始页面加载(或浏览器刷新)上工作,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问题的解决方案。我在目前正在进行的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问题:

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

答案 1 :(得分:6)

这解决了我的问题:

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

参考:Bootstrap-Select

答案 2 :(得分:0)

您可能正在使用咖啡来编写脚本,因此您可以写下:

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

答案 3 :(得分:0)

另一种方法可能是这样的:

$('.selectpicker').selectpicker('refresh');

来自文档:

要以编程方式使用JavaScript更新选择,请先操作选择,然后使用refresh方法更新UI以匹配新状态。在删除或添加选项时,或通过JavaScript禁用/启用选择时,这是必需的。
