一些coffeescript無法正常工作，可能與application.js和/或javascript插件有關

Question

我正在使用使用很多javascript插件的應用程序，這可能是問題所在。 我正在嘗試以最基本的方式（隱藏div）在最基本的頁面（home.html.erb）上使coffeescript工作。 Coffeescript在應用程序的某些部分有效，但大多數情況下不起作用。 Home.html.erb是static_pages控制器的一部分。 下面的代碼不會隱藏div。 任何幫助，將不勝感激

static_pages.js.coffee

jQuery ->
  $("#rubyPic").hide()
  $("#heroMain").hide()

home.html.erb

<div class="center hero-unit" id="heroMain">
    <h1>finance </h1>
    <p>
    This is the home page for the RoR 
    </p>

</div>

<div class="box closable-chat-box">
  <div class="box-content padded">

    <h3>
        Your Classes that you are a currently signed up for 
        are below: 
    </h3>
    <section id="rubyPic">
      <%= link_to image_tag("rails.png", alt: "Rails"), 'http://rubyonrails.org' %>
      <%= render 'home_courses' %>
    </section>

  </div>
 </div>

Answer 1

也許是因為這些線？

//= require jquery
...
//= require static_pages
//= require jquery191

嘗試刪除行//= require jquery191嗎？ 或者用它替換jquery 。 或最后插入static_pages 。
