Question

这是一个非常奇怪的故障。我的网站只是让我在首次加载页面时发送消息，如果我通过Chrome浏览器控制台通过App.room.speak创建消息，则消息发送和恢复工作正常（＆＃34;您好＆＃ 34）

下面是.coffee。它来自教程和本教程的C＆amp; P没有问题，所以我想知道为什么会这样。

App.room = App.cable.subscriptions.create "RoomChannel",
  connected: ->
    # Called when the subscription is ready for use on the server


  disconnected: ->
    # Called when the subscription has been terminated by the server

  received: (data) ->
    $('#messages').append('<br>'+data['message'])

  speak: (message) ->
    @perform 'speak', message: message

    $(document).on 'keypress', (event) ->
      if event.keyCode is 13# return = send
        App.room.speak event.target.value
        event.target.value = ''
        event.preventDefault()

的Gemfile：

source 'https://rubygems.org'

ruby "2.3.0"

gem 'rails',        '5.0.0.beta3'
gem 'bootstrap-sass'
gem 'sass-rails'
gem 'uglifier'  
gem 'faker'
gem 'coffee-rails'
gem 'jquery-rails'
gem 'turbolinks'  
gem 'jbuilder'
gem 'puma', '3.4.0'
gem 'carrierwave'
gem 'bootstrap-will_paginate'
gem 'execjs' 
gem 'actioncable', '~> 5.0.0.beta3'
gem 'sdoc', group: :doc

# Security
gem 'bcrypt'             

group :development, :test do
  gem 'sqlite3',     '1.3.9'
  gem 'byebug',      '3.4.0'
#  gem 'web-console'
  gem 'spring'     
end

group :test do
  gem 'minitest-reporters', '1.0.5'
  gem 'mini_backtrace',     '0.1.3'
  gem 'guard-minitest',     '2.3.1'
end

group :production do
  gem 'pg',             '0.17.1'
  gem 'rails_12factor', '0.0.2'
end

最后是我的application.html.erb文件

    <!DOCTYPE html>
<html>
<head>
  <title><%= full_title(@title) %></title>
  <%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
  <%= action_cable_meta_tag %>
  <%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
  <%= csrf_meta_tags %>

</html>


<!-- JQUERY STUFF -->
<script>

$(document).ready(function(){

  setTimeout(function(){ $('.fadeout').fadeTo(1000, 0) }, 4000);

  $(".slideanim2").each(function(){
    var pos = $(this).offset().top;

    $(this).addClass("slide");
  });

  $(window).scroll(function() {
    $(".slideanim").each(function(){
      var pos = $(this).offset().top;

      var winTop = $(window).scrollTop();
        if (pos < winTop + 600) {
          $(this).addClass("slide");
        }
    });
  });
})
</script>

请帮忙！
