从Rails中的Controller打开弹出窗口

我正在创建我的第一个示例Rails应用程序。我在我的应用程序中使用了rufus-scheduler,并在每10秒后调用控制器的动作。我的代码如下:

In config/initializers I've created task_scheduler.rb and it contains:

在config / initializers中我创建了task_scheduler.rb,它包含:

require 'rubygems'
require 'rufus/scheduler'
scheduler = Rufus::Scheduler.new
scheduler.every("10s") do
  MyTaskController.doSomething
end

I also created a controller named MyTaskController and code is:

我还创建了一个名为MyTaskController的控制器,代码是:

 class MyTaskController < ApplicationController
  def self.doSomething
    puts "some task"
  end
end

It works perfectly, but I want to show a popup alert instead of using puts function. Is it possible in rails to call a javascript alert or javascript:window.open from controller (my doSomething action)?

它工作得很好,但我想显示一个弹出警报,而不是使用puts函数。是否可以在rails中从控制器调用javascript警报或javascript:window.open(我的doSomething操作)?
