Jquery rails表单动态字段选择器

我在rails 3中使用嵌套的表单，我有一个动态字段，用户可以添加或删除该字段

我需要知道这些字段的jquery选择器，这样我就可以在字段之间进行一些javascript计算，目前动态字段有一个设置为当前日期时间的字段，人们通常如何处理动态字段验证

<%= nested_form_for [@project, @quote], :html => {:class =>'form-inline'} do |f| %>
<div>
  <%= f.hidden_field :project_id %>
  <%= f.label :name %>
  <%= f.text_field :name %>
  <%= f.label :status %>
  <%= f.text_field :status %>
</div>
  <p>
    <h4> Labour Items </h4>
  </p>
  <p>
    <%= f.fields_for :labouritems, :html => { :class => 'form-vertical' } do |builder| %>

    <%= builder.label :description %>
    <%= builder.text_field :description, :class => "input-medium" %>
    <%= builder.label :hours %>
    <%= builder.text_field :hours, :class => "input-mini" %>
    <%= builder.label :total %>
    <%= builder.text_field :total, :class => "input-mini" %>
    <%= builder.label "Mup/Hr" %>
    <%= builder.text_field :muphourrate, :class => "input-mini" %>
      <%= builder.label "Mup/Total" %>
    <%= builder.text_field :muptotal, :class => "input-mini" %>
    <%= builder.label "Mup/%" %>
    <%= builder.text_field :muppercent, :class => "input-mini" %>
    <%= builder.label "Contractor" %>

    <%= builder.autocomplete_field :contractor_name, autocomplete_contractor_firstname_contractors_path, :update_elements => {:id => "##{form_tag_id(builder.object_name, :contractor_id)}" , :hourly_rate => "##{form_tag_id(builder.object_name, :contractor_rate)}"   },:class => "input-small",:placeholder => "Seach" %>
    <%= builder.hidden_field :contractor_id  %>
    <%= builder.label "Rate/hr"  %>
    <%= builder.text_field :contractor_rate,:class => "input-mini" %>
    <%= builder.label "Work %" %>
    <%= builder.text_field :progress_percent, :class => "input-mini" %>
    <%= builder.label "Work $" %>
    <%= builder.text_field :progress_payment, :class => "input-mini" %>

    <%= builder.link_to_remove "Delete",:class => 'btn btn-small btn-danger'   %>

  <% end %>

  <%= f.link_to_add "Add Item", :labouritems, :class => 'btn btn-small btn-primary' %>
</p>

{:class=>'form-inline'}do | f |%>

我不知道您需要验证哪种类型的信息，但类似的内容应该会有所帮助。要验证的所有字段都需要一个类或id。如果需要以某种方式验证某个问题，请为其指定一个id，并使用

$（“#elements_id”）

与jQuery一起选择

$(".form-inline").submit(function(){

  $.each($(".input-mini"), function(){
    if($(this).val() == ""){
      $("#warnings").html("<p> Ooops, you forgot something </p>"); // Warn
      return false;  // Don't submit
    }
  }

});

$（“.form inline”）.submit（函数（）{
$.each（$（“.input mini”），函数（）{
if（$（this）.val（）==“”）{
$（“#warnings”）.html（oops，你忘了什么东西了；//Warn
返回false；//不提交
}
}
});
