有时候JavaScript运行完美，有时不会在轨道上的红宝石4

问题描述

我在日历中使用datepicker显示完美，但没有显示箭头按钮来更改月份。并且还会给出错误有时像这样：

  ActionController :: RoutingError（无路由匹配[GET]/ assets / images / ui -icons_ef8c08_256x240.png）
  

datepicker.js

（$（$）$（$）$（$）$ $ $ $ $ ）;

css

抱歉太长时间的问题，告诉我，如果我想念某件事。 / p>

非常感谢提前

编辑：
我观察到我删除公共/资产目录，然后输入rake资产：预编译此时间错误未显示，但箭头仍未显示。

解决方案

p>默认情况下，它被添加到rails 4中看起来像是turbolinks问题。在turbolinks $（文件）.ready并不总是触发。您可以在查看有关turbolinks的更多信息和一些建议如何使用你可以添加到一些链接

  data：{no_turbolink：true} 
  pre> 
 
 
如果您不需要，您也可以从gemfile中删除turbolinks。还要检查您是否在
  / assets / images / 
  
 
I  used datepicker in calendar it shows perfect but not shows the arrow button to change month. and also give error sometimes like this:
ActionController::RoutingError (No route matches [GET] "/assets/images/ui-icons_ef8c08_256x240.png")
datepicker.js
$(document).ready(function(){
  $('[data-behaviour~=datepicker]').datepicker();
});
csslink
sorry for too long question and tell me if i miss something.
Big thanks in advance
Edit:I observed that when i delete the public/assets directory and then enter rake assets:precompile this time error is not showing but arrow still is not showing.
 解决方案 
It looks like turbolinks problem which are added to rails 4 by default. In turbolinks $(document).ready is not always firing. You can see more information about turbolinks and some suggestions how to use them here railscast or you can add to some links
data: { no_turbolink: true }
You can also just remove the turbolinks from gemfile if you don't need them. Also check if you have the ui-icons_ef8c08_256x240.png in
/assets/images/
