如何加载特定于页面的 rails 4 js 文件? [英] How to load page specific rails 4 js files?

问题描述

我正在阅读有关资产管道的 Rails 指南文档.它指出，coffeescript 页面特定生成的文件如果清单上有 require_tree 指令，则默认情况下已准备好供用户使用.这对我不起作用，我必须包括这个

I am reading rails guides documentation for asset pipeline. It states that coffeescript page specific generated files are by default ready to user if there is a require_tree directive on the manifest. This is not working with me I have to do include this

<%= javascript_include_tag params[:controller] %>

在特定控制器上.我错过了什么?

on the specific controller. What am I missing ?

推荐答案

资产管道会将您的所有 JS 压缩到一个文件 application.js 中.为了为特定页面调用 JS，您需要通过控制器和操作来组织您的 JS.有一个 gem，RailsS​​cript 可以自动执行此操作，并且它与 Turbolinks 兼容，可以为您提供单页应用程序的感觉.

The asset pipeline will compress all of your JS into a single file, application.js. In order to call JS for a specific page, you will need to organize your JS by controller and action. There is a gem, RailsScript that does this automatically and it's compatible with Turbolinks which can give you a single page application feel.

RailsS​​cript 只需几分钟即可学会，https://github.com/gemgento/rails_script.

RailsScript only takes a few minutes to learn, https://github.com/gemgento/rails_script.

使用 rails 脚本的具体示例:

A specific example using rails script:

# app/assets/javascripts/users.js.coffee

window.App ||= {}
class App.Users extends App.Base

   show: ->
      alert('The users#show action!')
