Datatables.net (1.10.22) + Webpack Encore (1.11) + Symfony (5.2.6)

问题描述

我正在处理一个 Symfony 5.2.6 项目，我正在尝试在我的项目中使用 datatables.net 库，但找不到正确导入它的方法。

我使用了很多 js/jquery 库，除了数据表之外，一切都运行良好。（我正在使用 Metronic 管理模板）

这是我的 webpack.config.js :

const Encore = require('@symfony/webpack-encore');
const CopyWebpackPlugin = require('copy-webpack-plugin');

if (!Encore.isRuntimeEnvironmentConfigured()) {
    Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
}

Encore
    .setOutputPath('public/build/')
    .setPublicPath('/build')

    .addStyleEntry('basecss','./assets/sass/style.scss')
    .addStyleEntry('pluginscss','./assets/plugins/plugins.scss')
    .addStyleEntry('extrascss','./assets/css/extras.css')

    .addEntry('app','./assets/app.js')
    .addEntry('plugins','./assets/plugins/plugins.js')
    .addEntry('scripts','./assets/scripts.js')

    .addEntry('test','./assets/test.js')

    .addEntry('page-ms-liste','./assets/pages/matiereseche/liste.js')
    
    .addStyleEntry('page-login-css','./assets/pages/authentication/login.css')

    .enableStimulusBridge('./assets/controllers.json')
    
    .splitEntryChunks()
    
    .enableSingleRuntimeChunk()
    
    .cleanupOutputBeforeBuild()
    
    .enableBuildNotifications()
    
    .enableSourceMaps(!Encore.isProduction())
    
    .enableVersioning(Encore.isProduction())

    .configureBabel((config) => {
        config.plugins.push('@babel/plugin-proposal-class-properties');
    })
    
    .configureBabelPresetEnv((config) => {
        config.useBuiltIns = 'usage';
        config.corejs = 3;
    })

    // enables Sass/SCSS support
    .enableSassLoader()

    .addPlugin(new CopyWebpackPlugin({
        patterns: [
            { from: './assets/images',to: 'images' }
        ],}))

    .addLoader({
        test: require.resolve('jquery'),use: [{
            loader: 'expose-loader',options: {
                exposes: [
                    {
                        globalName: "$",override: true,},{
                        globalName: "jQuery",}
                ]
            }
        }]})

    .addLoader({
        test: '/datatables\.net.*/',use: [{
            loader: 'imports-loader',options: {
                imports: {
                    moduleName: 'jquery',name: '$',additionalCode: "var define = false;"
            }
        }]})


;
const config = Encore.getWebpackConfig();

module.exports = config;

我也尝试使用 .autoProvidejQuery()

在我的scripts.js里面我有：

window.jQuery = window.$ = require('jquery');
// ...    
require('datatables.net');
require('datatables.net-bs4');

然后在我的 js 文件中：

var t = $("#datatable");
        t.DataTable(.....)

错误：

未捕获的类型错误：$(...).DataTable 不是函数

我发现了很多关于这个主题的主题，但是我尝试了所有方法都没有成功（使用加载器，...）我也尝试从 CDN 和数据表导入 jquery，但我有一个 jquery 问题（jquery 未定义）

如果有人有想法...

谢谢。

解决方法

删除

window.jQuery = window.$ = require('jquery');

然后，你可以这样导入数据表：

import $ from "jquery";
require('datatables.net-bs4')( window,$ );

这样，DataTable 应该会被识别出来，你就可以使用它了。

经过相当长的时间测试 Stackoverflow 的各种答案后，我设法使它起作用（在 Guillaume F. 和 Dylan Kas 的帮助下）。

这些是文件：

webpack.config.js

const Encore = require('@symfony/webpack-encore');
const CopyWebpackPlugin = require('copy-webpack-plugin');

if (!Encore.isRuntimeEnvironmentConfigured()) {
    Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
}

Encore
    .setOutputPath('public/build/')
    .setPublicPath('/build')

     // Main Js file
    .addEntry('app','./assets/app.js')
     
    // In my case Datatable init code is in this file. Don't forget to load this asset from your template page with the shortcut : {{ encore_entry_script_tags('my-page') }}
    .addEntry('my-page','./assets/pages/my-page.js')

    //.. Other imports here ..
    /*.addEntry('scripts','./assets/scripts.js')*/

    .splitEntryChunks()

    .enableSingleRuntimeChunk()

    .cleanupOutputBeforeBuild()

    .enableBuildNotifications()

    .enableSourceMaps(!Encore.isProduction())

    .enableVersioning(Encore.isProduction())

    .configureBabel((config) => {
        config.plugins.push('@babel/plugin-proposal-class-properties');
    })

    .configureBabelPresetEnv((config) => {
        config.useBuiltIns = 'usage';
        config.corejs = 3;
    })
    
    .addPlugin(new CopyWebpackPlugin({
        patterns: [
            { from: './assets/images',to: 'images' }
        ],}))

;
const config = Encore.getWebpackConfig();

// Without this,I have issues with my DT.net requires
config.module.rules.unshift({
    parser: {
        amd: false,}
});

module.exports = config;

我的app.js文件

window.jQuery = window.$ = require('jquery');

require('bootstrap');

window.Popper = require('popper.js').default;

// Needed form Datatables Buttons plugin
window.JSZip = require('jszip');
const pdfMake = require('pdfmake/build/pdfmake.js');
const pdfFonts = require('pdfmake/build/vfs_fonts.js');
pdfMake.vfs = pdfFonts.pdfMake.vfs;


require('datatables.net')(window,$);
require('datatables.net-bs4')(window,$);
require('datatables.net-buttons/js/dataTables.buttons.min.js')(window,$);
require('datatables.net-buttons-bs4')(window,$);
require('datatables.net-buttons/js/buttons.flash.js')(window,$);
require('datatables.net-buttons/js/buttons.html5.js')(window,$);
require('datatables.net-buttons/js/buttons.print.js')(window,$);

我的packages.json：

{
    "dependencies": {
        // others imports above
        "bootstrap": "^4.6.0","datatables.net": "^1.10.24","datatables.net-autofill-bs4": "^2.3.5","datatables.net-bs4": "1.10.24","datatables.net-buttons-bs4": "^1.7.0","datatables.net-colreorder-bs4": "^1.5.2","datatables.net-fixedcolumns-bs4": "^3.3.2","datatables.net-fixedheader-bs4": "^3.1.7","datatables.net-keytable-bs4": "^2.5.3","datatables.net-responsive-bs4": "^2.2.6","datatables.net-rowgroup-bs4": "^1.1.2","datatables.net-rowreorder-bs4": "^1.2.7","datatables.net-scroller-bs4": "^2.0.3","datatables.net-select-bs4": "^1.3.1","jquery": "^3.6.0","jszip": "^3.5.0","pdfmake": "^0.1.36","popper.js": "^1.16.1",},"devDependencies": {
        "@symfony/stimulus-bridge": "^2.0.0","@symfony/webpack-encore": "^1.0.0","copy-webpack-plugin": "^8.1.0","core-js": "^3.0.0","expose-loader": "^2.0.0","imports-loader": "^2.0.0","lodash": "^4.17.13","regenerator-runtime": "^0.13.2","sass": "^1.32.8","sass-loader": "11.0.0","script-loader": "^0.7.2","stimulus": "^2.0.0","webpack-notifier": "^1.6.0"
    },"license": "UNLICENSED","private": true,"scripts": {
        "dev-server": "encore dev-server","dev": "encore dev","watch": "encore dev --watch","build": "encore production --progress"
    }
}

最后我的文件初始化了数据表（我每页使用一个条目 js 文件）： page.js

"use strict";

var MyPage = {
    init: function () {
        const table = $('#datatable').DataTable({
            buttons: [
                {
                    extend: 'print',exportOptions: {
                        columns: [0,1,2,3]
                    }
                },{
                    extend: 'excelHtml5',],columnDefs: [
                {
                    width: '75px',targets: 4,});

        $('#export_print').on('click',function(e) {
            e.preventDefault();
            table.button(0).trigger();
        });

        $('#export_excel').on('click',function(e) {
            e.preventDefault();
            table.button(1).trigger();
        });
    },};
jQuery(document).ready(function () {
    MyPage.init();
});

请注意，在我的情况下，我从 2 个 html 元素切换按钮。
