javascript - SF4/WWebpack - 未定义 Javascript 函数

Question

我正在使用 Symfony 的 WebPack.Encore 包，我意识到一件事是对于单个按钮 onclick = function ()，我的函数没有定义，而如果我把它放在 document.ready 中，它就可以工作。你能给我解释一下如何在 onclick 上调用这个函数吗？

// file.js
function newInvLine(){
  alert("Hi");
}

// html
<a href="#" onclick="newInvLine();">TEST</a>

我的 webpack.config

var Encore = require('@symfony/webpack-encore');

Encore
// directory where compiled assets will be stored
.setOutputPath('public/build/')
// public path used by the web server to access the output path
.setPublicPath('/public/build')
// only needed for CDN's or sub-directory deploy
//.setManifestKeyPrefix('build/')

/*
 * ENTRY CONFIG
 *
 * Add 1 entry for each "page" of your app
 * (including one that's included on every page - e.g. "app")
 *
 * Each entry will result in one JavaScript file (e.g. app.js)
 * and one CSS file (e.g. app.css) if you JavaScript imports CSS.
 */
.addEntry('app', './assets/js/app.js')
.addEntry('find_city_by_cp', './assets/js/find_city_by_cp.js')
.addEntry('calculSimulateur', './assets/js/file.js')
//.addEntry('page1', './assets/js/page1.js')
//.addEntry('page2', './assets/js/page2.js')

/*
 * 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())

// enables Sass/SCSS support
.enableSassLoader()

// uncomment if you use TypeScript
//.enableTypeScriptLoader()

// uncomment if you're having problems with a jQuery plugin
.autoProvidejQuery()
;

module.exports = Encore.getWebpackConfig();

您的函数不再“连接”到您的浏览器窗口，处理程序已更改。

这意味着我们必须让“窗口”对象知道您的新功能。

window.newInvLine = function() {
  alert("Hi");
};
