如何将 Javascript 文件加载到 rails html erb [英] how to load a Javascript file to rails html erb

问题描述

我正在尝试将如下 javascript 文件加载到我的 html.erb 文件中

Um trying to load a javascript file as follows to my html.erb file

 <script src="/public/javascripts/test.js" type="text/javascript" /> 

它在公共文件夹和根目录中可用

its available on the public folder and its in the root directory

root/public/javascript

root/public/javascript

但它给了我一个错误说

 "NetworkError: 404 Not Found  - http://0.0.0.0:3000/public/javascripts/test.js"

可能有什么问题?有没有其他方法可以在 Rails 中包含 javascipt 文件?

what could possibly wrong ? is there a different way to include a javascipt file in rails ?

推荐答案

如果 javascript 文件位于 Rails 3.x 的任何资产文件夹(资产、供应商、捆绑包)中，您可以将脚本添加到您的 html.erb 文件，添加以下内容:

If the javascript file is in any of the asset folders (assets, vendor, bundle) for Rails 3.x) you can add the script to your html.erb file by adding the following:

<%= javascript_include_tag('test.js') %>
