Ruby on rails rails中的ajax表单提交消息错误

项目

有一个

项目总监

，项目总监有属性

状态

早些时候，我没有使用ajax提交项目。\u每次都会重新加载director表单页面，并相应地访问提交状态。

现在，我使用ajax提交数据时不需要重新加载页面，但在状态值设置一次后，我无法隐藏，也无法显示提交时的任何消息。如何使用ajax特性在行中显示提交的值并在提交后隐藏表单

这是我目前的代码：-

index.html.erb

<% if project_site.project_directors.empty?%>
  <%= form_for ProjectDirector.new, :remote => true do |f| %>
    <td>
     <table class="approval-table">
      <tr>
       <td>
        <ul>
         <div>
          <div class="wrapper-class">
           <%= f.radio_button :status, true  %>
           <%= f.label :approve %>
           <br>
           <%= f.radio_button :status, false  %>
           <%= f.label :reject %>
          </div>
          <%=f.hidden_field :project_site_id, value: project_site.id%>
         </div>
        </ul>
       </td>
       <td>
        <%= f.hidden_field :user_id, value: current_user.id %>
        <%= f.submit 'Submit', :class => 'button primary small' %>
       </td>
      </tr>
     </table>
    </td>
  <% end %>
<% else %>
  <% project_site.project_directors.each do |project_director| %>
    <% if project_director.status == false %>
      <td class="rejected fi-x"><%= ' Rejected' %></td>
    <% elsif project_director.status == true %>
      <td class="approved fi-check"><%= " Approved" %></td>
    <% end %>
  <% end %>
<% end %>

在保存请求中调用success方法时，需要更新DOM。您可以通过创建一个

create.js.erb

文件来执行一些js

您可以将控制器更改为使用

响应

将HTML拆分为部分

您能检查网络选项卡以查看此请求是否正确通过吗？我没有更改您的代码。检查网络，现在提交表单时没有任何变化

def create
  @project_director =  ProjectDirector.new(remark_params)
  #redirect_to  directors_index_path, anchor: '#panel2'
  if @project_director.save
    if request.xhr?
      render json: { success: true }
    else
      redirect_to notice: "Thing was successfully created."
    end
  else
    render :new
  end
end

def create
  @project_director = ProjectDirector.new(remark_params)

  respond_to do |format|
    if @project_director.save
      format.js   { render layout: false }
      format.html { redirect_to notice: "Thing was successfully created." }
    else
      format.js   { render layout: false }
      format.html { render :new }
    end
  end
end
