如何在Rails 6的视图中使用JQueryUI [英] How to use JQueryUI in views in Rails 6

问题描述

我在Rails 6应用程序中使用JQuery和JQueryUI遇到困难.

I am having difficulty using JQuery and JQueryUI in a Rails 6 app.

JQuery和JqueryUI都可以在application.js中使用

JQuery and JqueryUI both work in application.js

但是，JQueryUI在视图中不起作用.如何在两种情况下都可以使用?我的代码在下面.

HOWEVER, JQueryUI is not working in views. How do I make it work in both cases? My code is below.

我跑了yarn add jquery

我跑了yarn add jquery-ui-dist

在 environment.js 中:

const { environment } = require('@rails/webpacker')
const webpack = require('webpack')

environment.plugins.prepend('Provide',
  new webpack.ProvidePlugin({
    $: 'jquery',
    jQuery: 'jquery'
  })
);

const aliasConfig = { 'jquery': 'jquery/src/jquery', 'jquery-ui': 'jquery-ui-dist/jquery-ui.js' };
environment.config.set('resolve.alias', aliasConfig);

module.exports = environment

在 application.js 中:

require("@rails/ujs").start()
require("@rails/activestorage").start()
require("channels")
require("jquery")
require("jquery-ui");
require("custom/scripts")

我在 custom/scripts.js 和 packs/search.js

custom/scripts.js 已加载到application.js中，如下所示:

custom/scripts.js is loaded in application.js and looks like this:

$(document).ready(function(){
  var test = $().jquery
  console.log('custom/scripts.js JQuery version ==> ' + test);

  var test_ui = $.ui ? $.ui.version || "pre 1.6" : 'jQuery-UI not detected';
  console.log('custom/scripts.js UI version ==> ' + test_ui);
});

packs/search.js 通过以下方式加载到视图中

packs/search.js is loaded in the view with

<%= javascript_pack_tag "search" %>

packs/search.js 看起来像这样(与custom/scripts.js完全相同):

packs/search.js looks like this (exact same as custom/scripts.js):

$(document).ready(function(){
  var test = $().jquery
  console.log('packs/search.js JQuery version ==> ' + test);
  
  var test_ui = $.ui ? $.ui.version || "pre 1.6" : 'jQuery-UI not detected';
  console.log('packs/search.js UI version ==> ' + test_ui);
});

控制台中的结果:

custom/scripts.js JQuery version ==> 3.5.1
custom/scripts.js UI version ==> 1.12.1
packs/search.js JQuery version ==> 3.5.1
packs/search.js UI version ==> jQuery-UI not detected

推荐答案

问题可能是Webpack如何解析插件.我已经删除了这一行

The problem is maybe how Webpack resolves the plugin. I have removed this line

 $: 'jquery'

在environment.js中的

似乎很有效！

in environment.js and seem likes it works!
