Javascript Ruby-on-Rails:openmodalbox-Link不'；t工作更新：链接到远程

我希望我的页面打开一个模式弹出框，因此我将此链接添加到我的视图文件：

  <%= link_to_remote '+ Add Discount', :url => {:controller => "parent_wise_fee_payments", :action => "new_instant_discount", :id => @financefee.id, :current_action => @target_action, :current_controller => @target_controller} %>

然后我创建了create_instant_折扣操作并使用以下代码创建了_instant_dicount.rjs：

page.replace_html 'modal-box', :partial => 'instant_discount_form'
page << "Modalbox.show($('modal-box'),  {title: ''});"

---

尝试创建新的即时折扣.rjs。然后把它放在那里：

page.replace_html 'modal-box', :partial => 'instant_discount_form'
page << "Modalbox.show($('modal-box'),  {title: ''});"

page.replace\u html“模式框”，：partial=>“即时折扣表单”
页
你能帮我找出我遗漏了什么吗

如果你没有看到任何结果，那么问题可能出在你的电脑上

Rails无法为您打开模型，它必须使用服务器返回的数据附加到DOM中。看起来您正在将请求发送到服务器好的，这只是一个将请求返回并附加到服务器的例子


代码

当前的代码非常随意，这就是我对您提供的代码所做的：

系统

您的问题不仅仅是没有收到数据的直接回报，还需要了解代码的结构（几乎就在那里）

现在，从path helper的荒谬之处，我相信您可以理解如何能够解决系统中的一些更深层次的问题。也就是说，你对你的控制者/行动很具体；它需要用于数据对象：

#config/routes.rb 
resources :finance_fees do
   resources :discounts
end

#app/controllers/discounts_controller.rb
class DiscountsController < ApplicationController
   def new
      @finance_fee = FinanceFee.find params[:finance_fee_id]
      @discount = @finance_fee.discounts.new
   end
   def create
      @finance_fee = FinanceFee.find params[:finance_fee_id]
      @discount = @finance_fee.discounts.new create_params          
   end
   private
   def create_params
      params.require(:discount).permit(:x, :y, :z)
   end
end

这会将数据异步发送到服务器，不会处理响应。如果您使用以下选项，它应该可以工作：

<%= link_to '+ Add Discount', :url => {:controller => "parent_wise_fee_payments", :action => "new_instant_discount", :id => @financefee.id, :current_action => @target_action, :current_controller => @target_controller}, remote: true %>

{:controller=>“家长明智的费用支付”，：action=>“新的即时折扣”，：id=>@financefee.id，：current\u action=>@target\u action，：current\u controller=>@target\u controller}，remote:true%>
非常感谢您的解释！
#app/views/controller/action.js.erb

$modalbox.html("<%=j render 'instant_discount_form' %>");
$('body').append(Modalbox.show($modalbox,  {title: ''}));

console.log($modalbox); //checks if $('modal-box') is valid
console.log(Modalbox.show($modalbox,  {title: ''})); // checks if Modal being called correctly.
