Ruby on Rails JavaScript资产路径

Question

我对为什么没有指定控制器的js文件感到有些困惑，比如说post.js不会在任何帖子视图中渲染任何Java脚本，例如document.write（“ hello”），而是在application.js之后做到每个视图

Answer 1

Its because in your application.html.erb you are including application.js with <%= javascript_include_tag "application" %> but your controller specified javascripts will render only after the specific action is executed. For example if you are creating a new post and your form has remote: true , After the form is submitted it will trigger the create action which will render create.js.erb .
