Javascript 如何使用jquery加载rails表单部分并作为一个表单提交

为了使我的rails html更具可读性，我将其中的几个部分提取为部分。然后，我使用jquery来呈现片段。现在的问题是，可以说表单已经完全“脱钩”，这意味着当我试图提交表单时，它的行为就好像部分不存在一样。我怀疑我不太了解表单是如何工作的，因为在与此相关的其他答案中，表单生成器似乎没有被提及

似乎与我想做的事情有关，但我觉得我太没经验了，无法正确把握

到目前为止，我的守则如下：

/assets/javascripts/work_order.js
$(document).ready(function(){
$('.best_in_place').best_in_place();
$('#work_order_dueDate').datepicker();
$.datepicker.setDefaults({ dateFormat: 'dd-mm-yy'});
var selection_made = false
$('#work_order_project_type_id').change(function(){
    if (!selection_made){
        selection_made = true
        var selection = $(this).find('option:selected').text();
        if (selection == "Variable Data Mailing"){
            $.get('/presort_informations/new');
            $.get('/printing_instructions/new');
        }
        else if (selection == "Mailing"){
            $.get('/presort_informations/new');            
        }
        else if (selection == "Print Job"){
            $.get('/printing_instructions/new');            
        }
    }
  });
});

然后

/views/work_orders/_form.html.erb

<%= form_for(@workorder) do |f| %>

  <% if @workorder.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@workorder.errors.count, "error") %> prohibited this workorder from being saved:</h2>

      <ul>
      <% @workorder.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>
  <fieldset class="general-info">
    <legend>General</legend>
    <div class="col-md-12">
      <div class="col-md-3">
        <div class="form-group">
          <%= f.label :Job_Title, class: "control-label" %>
          <%= f.text_field :title, class:"form-control" %>
        </div>

        <div class="form-group">
          <%= f.label :Project_Type, class: "control-label" %>
          <%= f.collection_select(:project_type_id, ProjectType.all, :id, :name, {:prompt => true}, {:class => "form-control"}) %>
        </div>
      </div>
    <div class="col-md-3">
      <div class="form-group">
        <%= f.label :Rep, class: "control-label" %>
        <%= f.text_field :rep, class:"form-control" %>
      </div>
      <div class="form-group">
        <%= f.label :Labels, class: "control-label" %>
        <%= f.collection_select(:labels_id, Labels.all, :id, :name, {:prompt => true}, {:class => "form-control"}) %>
      </div>
    </div>
    <div class="col-md-3">
      <div class= "form-group">
          <%= f.label :Due_Date, class: "control-label" %>
          <%= f.text_field :dueDate, class: "form-control" %>
      </div>
      <div class="form-group">
        <%= f.label :Project_Description, class: "control-label" %>
        <%= f.text_area :projectDescription,  class: "form-control" %>
      </div>
    </div>
  </div>
  </fieldset>
  <fieldset class="presort-information">

  </fieldset>
  <div class="col-md-6 printing">

  </div>
  <fieldset class="production-details">
    <legend>Production</legend>
    <%= f.fields_for :production_details, ProductionDetails.new do |ff| %>

    <%end%>
  </fieldset>
  <%= f.hidden_field(:number, :value => @workorder.number) %>
  <%= f.hidden_field(:client_id, :value => @workorder.client_id) %>
  <%= f.submit(class: "btn btn-default") %>
<% end %>

/views/work\u orders/\u form.html.erb
禁止保存此工单：



一般的
true}，{:class=>“表单控件”}）%>
true}，{:class=>“表单控件”}）%>
生产
@工单编号）%>
@工作订单.客户id）%>

作为其中一个部分的示例：

/app/views/presort_informations/new.js.erb
$('.presort-information').append( '<%= j render("presort_informations/form") %>' );

/app/views/presort_informations/_form.html.erb
<legend>Mailing</legend>
<%= fields_for :presort_information, PresortInformation.new do |ff| %>
.
.
.
<% end %>

/app/views/presort\u informations/new.js.erb
$（'.presort信息'）。追加（''）；
/app/views/pressort_informations/_form.html.erb
邮寄
.
.
.

我真的不知道如何将这一切联系在一起，以便我可以根据选择框加载部分内容，然后将它们全部作为一个表单提交

编辑： 我发现它处理相同的问题，但我怀疑，因为我在加载页面后呈现分部，所以我不再能够访问form builder变量

$('.presort-information').append( '<%= j render("presort_informations/form", f: f) %>' );

$（'.presort信息'）。追加（''）；

---

调用时给出一个未定义的变量错误。我仍然不知道如何弥合jquery和rails之间的差距。

结果表明，这是一个相对容易的解决方案（如果对我来说是新概念的话） 首先，加载每个DOM部分以及隐藏部分

<%= form_for(@workorder) do |f| %>
  <% if @workorder.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@workorder.errors.count, "error") %> prohibited this workorder from being saved:</h2>
      <ul>
      <% @workorder.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <fieldset id="general-info-partial">
    <%=render("genInfo", f: f)%>
  </fieldset>
  <fieldset id="presort-information-partial">
    <%=render("presort_informations/form",  f: f)%>
  </fieldset>
  <div class="col-md-6">
    <fieldset id="printing-information-partial">
    <%=render("printing_instructions/form", f: f)%>
    </fieldset>
  </div>
  <fieldset id="production-details-partial">
    <%=render("production_details/form", f: f) %>
  </fieldset>
  <%= f.hidden_field(:number, :value => @workorder.number) %>
  <%= f.hidden_field(:client_id, :value => @workorder.client_id) %>
  <input type="submit" value="Submit" class="btn btn-default">
<% end %>

<div id="hidden-general-info" class="hidden"></div>

<div id="hidden-presort-information" class="hidden"></div>

<div id="hidden-printing-information" class="hidden"></div>

基本上，我的想法是加载所有内容，就好像我要全部使用一样，然后将部分内容移动到DOM的一个隐藏部分，然后在用户做出选择时使用JS将它们放回

$(document).ready(function(){
$('.best_in_place').best_in_place();
$('#work_order_dueDate').datepicker();
$.datepicker.setDefaults({ dateFormat: 'dd-mm-yy'});

var presortFields = $('#presort-information-partial');
var printingFields = $('#printing-information-partial');

var presortHidden = $('#hidden-presort-information');
var printingHidden = $('#hidden-printing-information');

presortHidden.html(presortFields.html());
presortFields.html('');

printingHidden.html(printingFields.html());
printingFields.html('');

$('#work_order_project_type_id').change(function(){

        var selection = $(this).find('option:selected').text();

        if (selection == "Variable Data Mailing"){
            if (printingFields.html() == '' && presortFields.html() == ''){
                printingFields.html(printingHidden.html()).hide().slideDown();
                presortFields.html(presortHidden.html()).hide().slideDown();
            }
            else if(printingFields.html() == '' && !(presortFields.html() == '')){
                printingFields.html(printingHidden.html()).hide().slideDown();
            }
            else if(!(printingFields.html() == '') && presortFields.html() == ''){
                presortFields.html(presortHidden.html()).hide().slideDown();
            }
        }
        else if (selection == "Mailing"){
            if(!(printingFields.html() == '')){
                printingFields.slideUp();
                printingFields.html('');
                presortFields.html(presortHidden.html()).hide().slideDown();

            }else{
                presortFields.html(presortHidden.html()).hide().slideDown();
            }

        }
        else if (selection == "Print Job"){
            printingFields.html(printingHidden.html()).hide().slideDown();
            presortFields.slideUp();
            presortFields.html('');
        }
});
