在我的Rails 6项目中,我一直在尝试使用资产管道来让application.js
使用jQuery和app/assets/javascript/event_index.js
处的JavaScript文件,但两者都不起作用。当我加载网页时,我得到了一个Uncaught ReferenceError: $ is not defined
,当我点击东西时,我的JavaScript代码没有做任何事情。
我尝试过的事情:
- this StackOverflow question的最佳答案表明,我可以编写
//=require events_index
来获取events_index. js,但这并没有做任何事情 - 我没有意识到我的
//= require
行必须在header中。当我改变它时,它仍然没有帮助 - 我跑了
gem 'jquery-rails'
- 我以前使用的是
$(document).ready()
,但显然因为Rails 6使用TurboLinks,所以它不再起作用,所以我更改了它
以下是我的application.js文件的全文:
// This file is automatically compiled by Webpack, along with any other files
// present in this directory. You're encouraged to place your actual application logic in
// a relevant structure within app/javascript and only use these pack files to reference
// that code so it'll be compiled.
//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require events_index
require("@rails/ujs").start()
require("turbolinks").start()
require("@rails/activestorage").start()
require("channels")
// Uncomment to copy all static images under ../images to the output folder and reference
// them with the image_pack_tag helper in views (e.g <%= image_pack_tag 'rails.png' %>)
// or the `imagePath` JavaScript helper below.
//
// const images = require.context('../images', true)
// const imagePath = (name) => images(name, true)
$( document ).on('turbolinks:load', function() {
console.log( "ready!" );
});
谢谢你的帮助!

Rails 6默认自带webpacker,你应该通过yarn安装jquery并通过webpacker加载它。
