Question

我需要data-toggle =＆＃34; modal＆＃34;中的选定值。我得到了值但无法分配给ruby变量，所以我无法获取我想要的数据。

<%= form_for(:repair, :url => { :controller => "owners", :action => 'property_repairs',:owner_id => current_user.owner.slug }) do |f| %>

 <%= collection_select(:property,:id,Property.where(owner_id: @owner.id, property_active: true).order(created_at: :desc),:id,:property_address,{:prompt => 'please select the property for Repair'},{class: "form-control"}) %>

 <%= f.submit 'Repair', :class => 'btn btn-primary' %>

 <% @repair = Repair.where(:owner_id => @owner.id)%>
<%end%>

<% @repair = Repair.where(:owner_id => @owner.id)%>

  <% @repair.each do |repair| %>      

  <%property = Property.find(repair.property_id)%>

  <tr>
  <td class="input-group-addon "> <%=property.property_address %></td> 
  <td class="input-group-addon"> <%= repair.category %></td> 
  <td class="input-group-addon"> <%= repair.start_date %></td>
  <td class="input-group-addon"> <%= repair.end_date%></td>
  <td class="input-group-addon"> <%= repair.cost %></td>
  <div id="pop">


  <td button type="button" data-id = "<%=repair.id%>" class="input-group-addon" data-toggle="modal" data-target="#myPop">
    <h class="text-primary text-left">View</h>
       </td>
</tr>
  <%end%>

我给了＆＃34;模态＆＃34;在同一个html.erb中。在这里，我想要我选择的数据

   <div class="modal fade" id="myPop" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
   <div class="modal-dialog">
   <div class="modal-content">
    <div class="modal-header">
      <div class="modal-body">
     <div>


     <input id = "myPop" value ="">  


    </div>
   </div>
   </div>
    </div>

在脚本中我获得了价值，但无法在Modal中分配，因为它有输入值

 <script>

 $(document).on("click", ".input-group-addon", function () {
 var myBookId = $(this).data('id');
 var value =    $(".modal-body #myPop").val( myBookId );
 });
 </script>

提前致谢

如果你想在DB中存储该值，你应该使用AJAX来调用ruby方法。否则，您将无法将javascript-var分配给ruby-var。

使用以下命令查看link_to或form_for：remote =＆gt;真实选择：
