Rails不会从link_to在Chome中加载js [英] Rails not loading js in Chome from link_to

问题描述

我的rails应用程序在通过link_to helper发送到页面后似乎不会加载某些javascript行为。这发生在Chrome浏览器，但不是IE浏览器（这让我很难说）。我已经看到Chrome不会在bootstrap-switch的多个页面中加载行为，以及我在源代码树中的某些自定义函数。这些将会在我从Chrome重新加载页面后起作用，但不会超出初始link_to。

这是我的application.js：

  // =需要jquery 
 // =需要jquery_ujs 
 // =需要turbolinks 
 / / = require_tree。 
 // =需要引导程序
 // =需要引导程序开关
 // =需要jquery-placeholder 
 // =需要jquery_nested_form 
  

Chrome是如何从link_to helper接收或呈现javascript的方式存在一些已知限制？请让我知道我是否可以提供任何有助于解决此问题的其他信息。

解决方案

我可以从你的 application.js 使用 turbolink 。

使用turbolink时， $（document）.ready（function（）{.. ）在点击内部链接时被忽略，因为页面不会以传统方式实际重新加载。 b

你有两个选择，重写/重构你的JS，以便它可以很好地与turbolinks搭配（通过没有页面特定的JS包括，通过适当地确定你的事件等等），或者你可以禁用turbolink如果你不想使用它：

1. 从你的 Gemfile


2. 从 application.js 中移除 // = require turbolinks


3. 在您的版面中删除对data-turbolinks-track=> true application.html.erb 。

My rails application does not seem to be loading some javascript behavior after being sent to a page via the link_to helper. This is happening in Chrome, but not IE (which hurts me to say). I've seen Chrome not loading behavior in multiple pages for bootstrap-switch, and for some custom functions that I have in my source tree. These will work after I reload the page from Chrome, but not off of the initial link_to.

Here is my application.js:

//= require jquery
//= require jquery_ujs
//= require turbolinks
//= require_tree .
//= require bootstrap
//= require bootstrap-switch
//= require jquery-placeholder
//= require jquery_nested_form

Is there some known limitation in how Chrome receives or renders javascript from the link_to helper? Please let me know if I can provide any additional information that will be helpful to resolve this.

解决方案

I can see from your application.js that you're using turbolinks.

When using turbolinks, $(document).ready(function() { .. is ignored when clicking on internal links because the page never actually reloads in the traditional way.

You have a couple of alternatives, rewrite/restructure your JS so that it plays nicely with turbolinks (by not having page-specific JS includes, by scoping your events appropriately, etc) or you can disable turbolinks if you don't want to use it by:

1. removing it from your Gemfile
2. remove the //= require turbolinks from your application.js
3. remove the 2 references to "data-turbolinks-track" => true in your layouts/application.html.erb.
