页面提交一个购物链接，服务器端获取商品信息返回页面 V 端代码 1

<%= form_for @product, html: {class: 'form-vertical'}, remote: true do |f| %>
    <fieldset>
      <div class="form-group">
        <div class="col-xs-10 col-sm-10">
          <%= f.text_field :buy_link, class: "form-control", placeholder: "http://item.taobao.com/item.htm?id=42249333320" %>
        </div>
        <div class="col-xs-2 col-sm-2">
          <%= f.submit "确认采集", class: 'btn btn-primary', data: {disable_with: "正在采集..."} %>
        </div>
      </div>
    </fieldset>
<% end %>

C 端代码 1

good = TaoBaoApi::Good.new params[:product][:buy_link]
 item = good.get_info
 respond_to do |format|
   format.json { render :text => { :find => "NO",:data =>item}.to_json }
 end

js 代码

$(document).ready(function () {
    $("#new_product").on("ajax:success", function (xhr, data, status) {
。。。。。。。。。。。。。。。。。。。

这个是正常的，我想讲 v 端和 c 端修改一下成为 2，结果 js 获取不到数据了 V 端代码 2

<form class="form-horizontal"  id="new_product1"  method="post" data-remote="true" accept-charset="UTF-8" action="/products/getgood/">

      <fieldset>
        <div class="form-group">

          <div class="col-xs-8 col-sm-8">
            <input class="form-control" id="buy_link" name="buy_link" placeholder="copy item link" type="url" />
          </div>

          <div class="col-xs-4 col-sm-4">
            <button class="btn btn-primary" type="submit"><i class="fa fa-plus fa-lg"></i>&nbsp; 载入</button>
          </div>
        </div>
      </fieldset>
    </form>

C 端代码 2

def getgood
  good = TaoBaoApi::Good.new params[:buy_link]
  item = good.get_info
   render :text => { :find => "NO",:data =>item}.to_json
end
