如果有人能展示在 rails 6 或 rails 7 Alpha 2 引擎中使用 jquery ui 所需的确切步骤,我将不胜感激。 我无法让 importmap-rails 在 Rails 7 引擎中工作,也无法让 webpacker 在 Rails 6 引擎或 Rails 7 alpha 2 引擎中工作。 给定一个名为 custom_page 的引擎,使用
rails plugin new custom_page --mountable --full
我将 jquery-ui-rails 作为依赖包含在 gemspec 中。
spec.add_dependency 'jquery-ui-rails'
也许这应该是一个 runtime_dependency? 完整的依赖列表是
spec.add_dependency "rails", "~> 7.0.0.alpha2"
spec.add_dependency 'new_ckeditor'
spec.add_dependency 'ancestry'
spec.add_dependency 'friendly_id', '>= 5.4.0'
spec.add_dependency 'pg_search'
spec.add_dependency 'carrierwave', '~> 2.0'
spec.add_dependency 'carrierwave-imageoptimizer'
spec.add_dependency 'sassc-rails', '~> 2.0.0'
spec.add_dependency 'pg', '~> 1.1'
spec.add_dependency 'jquery-rails'
spec.add_dependency 'jquery-ui-rails'
spec.add_development_dependency "puma"
#Testing Gems
spec.add_development_dependency "rspec-rails", '>= 5.0'
spec.add_development_dependency "factory_bot_rails"
spec.add_development_dependency "guard-rspec"
spec.add_development_dependency 'capybara', '>= 3.32'
spec.add_development_dependency 'selenium-webdriver'
spec.add_development_dependency 'launchy'
spec.add_development_dependency 'database_cleaner-active_record'
我在 engine.rb 中要求相同
require 'jquery-ui-rails'
require 'friendly_id'
require 'ancestry'
module CustomPage
class Engine < ::Rails::Engine
isolate_namespace CustomPage
config.generators do |g|
g.test_framework :rspec,
fixtures: false,
request: false,
view_specs: false,
helper_specs: false,
controller_specs: false,
routing_specs: false
g.fixture_replacement :factory_bot
g.factory_bot dir: 'spec/factories'
end
end
end
我在 View 中添加了一个简单的测试
<p id="notice"><%= notice %></p>
<script type='text/javascript'>
$(function() {
$('.datepicker').datepicker();
});
</script>
我已将要求包含在 app/assets/stylesheets/custom_page/application.css
/*
* This is a manifest file that'll be compiled into application.css, which will include all the files
* listed below.
*
* Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
* or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
*
* You're free to add application-wide styles to this file and they'll appear at the bottom of the
* compiled file so the styles you add here take precedence over styles defined in any other CSS/SCSS
* files in this directory. Styles in this file should be added after the last require_* statement.
* It is generally better to create a new file per style scope.
*
*= require_tree .
*= require_self
*/
/*
*= require jquery-ui
*/
还有在 app/assets/config/custom_page_manifest.js 中
//= link_directory ../stylesheets/custom_page .css
//= require jquery-ui
在 firefox 中检查浏览器控制台时出现错误显示
Uncaught ReferenceError: $ is not defined
我在这里显然展示了一个 Rails 7 alpha 2 示例,但是使用 rails 6.1.4 时也会出现同样的问题
此练习的目的是使我能够使用 jquery 库 jqtree,如果我能够使用 importmap-rails,它的设置将很简单,但是,根据我公开的尚未回答的问题 here,我做不到。
所以我真的想问如何在 Rails 6.1.4 引擎或 Rails 7 alpha 2 库中使用 jquery 库
最佳答案
这并不像我想象的那么简单。首先,jquery-ui-rails
和 jquery-rails
似乎已经过时了。我认为你不应该使用那些 gem 。我们可以使用 importmaps 因为我们有 set it up已经为引擎。但用途不仅限于引擎。
# config/importmap.rb
# NOTE: pin jquery to jsdelivr. this will make jquery global on import;
# jspm wraps packages in a module [1], so jquery is not available globally.
pin "jquery", to: "https://cdn.jsdelivr.net/npm/jquery@3.6.0/dist/jquery.js"
# NOTE: a few answers suggested `jquery-ui-dist`. I couldn't add it with
# `bin/importmap`; use https://generator.jspm.io/ to get the url.
pin "jquery-ui-dist", to: "https://ga.jspm.io/npm:jquery-ui-dist@1.13.1/jquery-ui.js"
# works fine
pin "jqtree", to: "https://ga.jspm.io/npm:jqtree@1.6.2/lib/tree.jquery.js"
# [1] someone, please, link to/explain what jspm does exactly to cause this.
// app/javascript/application.js
import "jquery";
import "jquery-ui-dist";
import "jqtree";
console.log(window.$); // jQuery is already global
console.log($.ui); // jquery-ui initialized on import
console.log($().tree); // jqtree also initialized
如果出于某种原因你想坚持使用 jspm,可以使用动态 import()
加载 jquery 插件。
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/import#dynamic_imports
# config/importmap.rb
pin "jquery", to: "https://ga.jspm.io/npm:jquery@3.6.0/dist/jquery.js"
pin "jquery-ui-dist", to: "https://ga.jspm.io/npm:jquery-ui-dist@1.13.1/jquery-ui.js"
pin "jqtree", to: "https://ga.jspm.io/npm:jqtree@1.6.2/lib/tree.jquery.js"
// app/javascript/application.js
import jQuery from "jquery";
// NOTE: keep in mind, these will be lazily loaded; use first method if this
// doesn't work in your set up.
import("jquery-ui-dist");
import("jqtree");
console.log(window.$); // undefined
console.log(window.jQuery); // undefined
console.log(jQuery().ui); // undefined
console.log(jQuery().tree); // undefined
// NOTE: make jquery global
window.$ = window.jQuery = jQuery;
对于带有 jquery-ui-rails
和 jquery-rails
gem 的 rails 6 设置。确保你也需要 jquery。不要触摸 manifest.js,您不是在预编译 jquery,您是在预编译已经包含 jquery 的 application.{css,js}。您还必须将 require
添加到 application.js。
https://github.com/rails/jquery-rails#installation
https://github.com/jquery-ui-rails/jquery-ui-rails#require-everything
// app/assets/javascripts/application.js
//= require jquery
//= require jquery-ui
/* app/assets/stylesheets/application.css */
/*= require jquery-ui */
