问题描述
我已按照本指南将引导程序添加到我的 Symfony 5.3 设置中:https://symfony.com/doc/current/frontend/encore/bootstrap.html
这就是我的 app.js
的样子:
import './styles/app.scss';
const $ = require('jquery');
global.$ = global.jQuery = $;
require('bootstrap');
这就是我的 base.html.twig
的样子:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>{% block title %}{% endblock %}</title>
{% block stylesheets %}
{{ encore_entry_link_tags('app') }}
{% endblock %}
{% block javascripts %}
{{ encore_entry_script_tags('app') }}
{% endblock %}
</head>
<body>
{% block body %}{% endblock %}
</body>
</html>
这就是我的 webpack.config.js
的样子:
const Encore = require('@symfony/webpack-encore');
// Manually configure the runtime environment if not already configured yet by the "encore" command.
// It's useful when you use tools that rely on webpack.config.js file.
if (!Encore.isRuntimeEnvironmentConfigured()) {
Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
}
Encore
// directory where compiled assets will be stored
.setOutputPath('public/build/')
// public path used by the web server to access the output path
.setPublicPath('/build')
// only needed for CDN's or sub-directory deploy
//.setManifestKeyPrefix('build/')
/*
* ENTRY CONFIG
*
* Each entry will result in one JavaScript file (e.g. app.js)
* and one CSS file (e.g. app.css) if your JavaScript imports CSS.
*/
.addEntry('app','./assets/app.js')
// enables the Symfony UX Stimulus bridge (used in assets/bootstrap.js)
.enableStimulusBridge('./assets/controllers.json')
// When enabled,Webpack "splits" your files into smaller pieces for greater optimization.
.splitEntryChunks()
// will require an extra script tag for runtime.js
// but,you probably want this,unless you're building a single-page app
.enableSingleRuntimeChunk()
/*
* FEATURE CONFIG
*
* Enable & configure other features below. For a full
* list of features,see:
* https://symfony.com/doc/current/frontend.html#adding-more-features
*/
.cleanupOutputBeforeBuild()
.enableBuildNotifications()
.enableSourceMaps(!Encore.isProduction())
// enables hashed filenames (e.g. app.abc123.css)
.enableVersioning(Encore.isProduction())
.configureBabel((config) => {
config.plugins.push('@babel/plugin-proposal-class-properties');
})
// enables @babel/preset-env polyfills
.configureBabelPresetEnv((config) => {
config.useBuiltIns = 'usage';
config.corejs = 3;
})
// enables Sass/SCSS support
.enableSassLoader()
// uncomment if you use TypeScript
//.enableTypeScriptLoader()
// uncomment if you use React
//.enableReactPreset()
// uncomment to get integrity="..." attributes on your script & link tags
// requires WebpackEncoreBundle 1.4 or higher
//.enableIntegrityHashes(Encore.isProduction())
// uncomment if you're having problems with a jQuery plugin
.autoProvidejQuery()
;
module.exports = Encore.getWebpackConfig();
现在当尝试使用以下功能时:
{% extends 'base.html.twig' %}
{% block body %}
<div class="dropdown">
<button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
Dropdown button
</button>
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<a class="dropdown-item" href="#">Action</a>
<a class="dropdown-item" href="#">Another action</a>
<a class="dropdown-item" href="#">Something else here</a>
</div>
</div>
{% endblock %}
当我点击按钮时没有任何反应,没有显示“下拉菜单”。我的错误日志中没有任何错误。
现在,当我从 CDN 手动加载 bootstrap/jquery 并将它们包含在我的 base.html 中时,它确实可以工作。
请帮忙!
