jquery - 语义 UI 下拉菜单功能在 Rails 6 中不起作用

问题描述

我在 gemfile 中添加了语义 ui gem，一切正常，但下拉菜单不起作用。我在任何地方都没有找到任何解决方案，
这是在 rails6 中使用的 gem 的问题吗？
这是 application.js 文件中的 javascript 代码。

require("jquery")
require("@rails/ujs").start()
require("turbolinks").start()
require("@rails/activestorage").start()
require("channels")
require("semantic-ui")
require("bootstrap/dist/js/bootstrap")

// 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(){
    $('.ui .dropdown').dropdown();
})

我在 chrome 开发工具的控制台中收到此错误。

解决方案

按照这些步骤让 Rails 6 使用语义 ui 下拉菜单

用纱线添加包：

yarn add jquery popper.js semantic-ui-sass

在 config/webpack/environment.js 添加以下内容：

const webpack = require("webpack")
 
environment.plugins.append("Provide", new webpack.ProvidePlugin({
  $: 'jquery',
  jQuery: 'jquery',
  Popper: ['popper.js', 'default']
}))

在 app/javascript/packs/application.js 添加以下内容：

require("semantic-ui-sass")

在 app/javascript/packs/application.js

$(document).on("turbolinks:load", () => $(".ui.dropdown").dropdown());
