我在使用Angular 2/4组件中的$('#modal-id')。modal(' show')函数打开模态时遇到问题。在缩小问题范围之后,我认为它与我的webpack加载jquery和bootstrap依赖关系有关。
我有两个webpack配置。一个用于捆绑所有角度组件等,另一个用于编译所有依赖项。
这是我的webpack.config:
const path = require('path');
const webpack = require('webpack');
const merge = require('webpack-merge');
const CheckerPlugin = require('awesome-typescript-loader').CheckerPlugin;
module.exports = (env) => {
// Configuration in common to both client-side and server-side bundles
const isDevBuild = !(env && env.prod);
const sharedConfig = {
stats: { modules: false },
context: __dirname,
resolve: { extensions: [ '.js', '.ts' ] },
output: {
filename: '[name].js',
publicPath: '/dist/' // Webpack dev middleware, if enabled, handles requests for this URL prefix
},
module: {
rules: [
{ test: /\.ts$/, include: /ClientApp/, use: ['awesome-typescript-loader?silent=true', 'angular2-template-loader'] },
{ test: /\.html$/, use: 'html-loader?minimize=false' },
{ test: /\.css$/, use: [ 'to-string-loader', isDevBuild ? 'css-loader' : 'css-loader?minimize' ] },
{ test: /\.(png|jpg|jpeg|gif|svg)$/, use: 'url-loader?limit=25000' }
]
},
plugins: [new CheckerPlugin()]
};
// Configuration for client-side bundle suitable for running in browsers
const clientBundleOutputDir = './wwwroot/dist';
const clientBundleConfig = merge(sharedConfig, {
entry: { 'main': './ClientApp/main.ts' },
output: { path: path.join(__dirname, clientBundleOutputDir) },
plugins: [
// new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery', jquery: 'jquery' }),
new webpack.DllReferencePlugin({
context: __dirname,
manifest: require('./wwwroot/dist/vendor-manifest.json')
})
].concat(isDevBuild ? [
// Plugins that apply in development builds only
new webpack.SourceMapDevToolPlugin({
filename: '[file].map', // Remove this line if you prefer inline source maps
moduleFilenameTemplate: path.relative(clientBundleOutputDir, '[resourcePath]') // Point sourcemap entries to the original file locations on disk
})
] : [
// Plugins that apply in production builds only
new webpack.optimize.UglifyJsPlugin()
])
});
return [clientBundleConfig];
};
这是我的webpack.vendor.config.js:
const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require('extract-text-webpack-plugin');
const merge = require('webpack-merge');
module.exports = (env) => {
const extractCSS = new ExtractTextPlugin('vendor.css');
const isDevBuild = !(env && env.prod);
const sharedConfig = {
stats: { modules: false },
resolve: { extensions: [ '.js' ] },
module: {
rules: [
{ test: /\.(png|woff|woff2|eot|ttf|svg)(\?|$)/, use: 'url-loader?limit=100000' }
]
},
entry: {
vendor: [
'@angular/animations',
'@angular/common',
'@angular/compiler',
'@angular/core',
'@angular/forms',
'@angular/http',
'@angular/platform-browser',
'@angular/platform-browser-dynamic',
'@angular/router',
'ag-grid-angular/main',
'ag-grid/dist/styles/ag-grid.css',

'bootstrap',
'bootstrap/dist/css/bootstrap.css',
'es6-shim',
'es6-promise',
'event-source-polyfill',
'jquery',
'zone.js',
]
},
output: {
publicPath: '/dist/',
filename: '[name].js',
library: '[name]_[hash]'
},
plugins: [
new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery', jquery: 'jquery' }), // Maps these identifiers to the jQuery package (because Bootstrap expects it to be a global variable)
new webpack.ContextReplacementPlugin(/\@angular\b.*\b(bundles|linker)/, path.join(__dirname, './ClientApp')), // Workaround for https://github.com/angular/angular/issues/11580
new webpack.ContextReplacementPlugin(/angular(\\|\/)core(\\|\/)@angular/, path.join(__dirname, './ClientApp')), // Workaround for https://github.com/angular/angular/issues/14898
new webpack.IgnorePlugin(/^vertx$/) // Workaround for https://github.com/stefanpenner/es6-promise/issues/100
]
};
const clientBundleConfig = merge(sharedConfig, {
output: { path: path.join(__dirname, 'wwwroot', 'dist') },
module: {
rules: [
{ test: /\.css(\?|$)/, use: extractCSS.extract({ use: isDevBuild ? 'css-loader' : 'css-loader?minimize' }) }
]
},
plugins: [
extractCSS,
new webpack.DllPlugin({
path: path.join(__dirname, 'wwwroot', 'dist', '[name]-manifest.json'),
name: '[name]_[hash]'
})
].concat(isDevBuild ? [] : [
new webpack.optimize.UglifyJsPlugin()
])
});
return [clientBundleConfig];
}
最初。在我的组件中,当我调用$('#modal-id')。modal(' show')从我的组件中得到$是未定义的。我通过在我的webpack.config.js中添加以下行来解决这个问题(我已经在我的供应商配置中使用了它)
new webpack.ProvidePlugin({ $: 'jquery', jQuery: 'jquery', jquery: 'jquery' })
现在jquery似乎工作正常,但是,引导程序扩展似乎不起作用。
我花了好几天时间查看其他相似的问题,例如:
Bootstrap plugins firing "is not a function"
但是在我的案例中没有答案或没有答案。
希望有人能提供帮助。
