来自其他类的Webpack访问类
问题描述:
我想从其他类的webpacked访问类功能。 我:来自其他类的Webpack访问类
var App = function() {
getResponsiveBreakpoint: function(size) {
var sizes = {
'xs' : 480, // extra small
'sm' : 768, // small
'md' : 992, // medium
'lg' : 1200 // large
};
return sizes[size] ? sizes[size] : 0;
}
}
,我想从使用此功能:
var Layout = function() {
var resBreakpointMd = App.getResponsiveBreakpoint('md');
}
这些类webpacked,这里的配置:
var path = require('path'),
webpack = require('webpack'),
ExtractTextPlugin = require("extract-text-webpack-plugin"),
autoprefixer = require('autoprefixer'),
precss = require('precss'),
ProvidePlugin = require('webpack/lib/ProvidePlugin'),
jsPath = './js',
jsLayoutPath = './js/layout',
cssPath = './css',
cssLayoutPath = './css/layout',
cssThemesPath = './css/layout/themes';
module.exports = {
entry: {
login: [jsPath + '/login.js', cssPath + '/login.css'],
layout: [jsLayoutPath + '/layout.js', cssLayoutPath + '/layout.css'],
custom: cssLayoutPath + '/custom.css',
vendor: [
cssPath + '/bootstrap.css',
cssPath + '/bootstrap-switch.css',
cssPath + '/font-awesome.css',

cssPath + '/datatables.css',

jsPath + '/app.js'
],
respond: jsPath + '/respond.src.js',
excanvas: jsPath + '/excanvas.js'
},
output: {
path: __dirname + "/../../web/assets/js/", publicPath: '/assets/js/', filename: "[name].js"
},
module: {
loaders: [
{
test: /\.css$/,
exclude: /node_modules/,
loader: ExtractTextPlugin.extract("style-loader", "css-raw-loader!postcss-loader")
},
{ test: /jquery\.js$/, loader: 'expose?$' },
{ test: /jquery\.js$/, loader: 'expose?jQuery' },
{ test: /datatables\.js$/, loader: 'expose?DataTable' },
{ test: /jquery\.form\.js$/, loader: "imports?define=>false" },
{
test: /\.js(x)?$/,
exclude: /node_modules/,
loader: 'babel',
query: {
plugins: [
"transform-class-properties"
],
"presets": [
"stage-0",
"es2015",
"react"
],
compact: false
}
},
],
postcss: function() {
return [autoprefixer, precss];
}
},
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery",
"window.jQuery": "jquery",
"DataTable": "datatables.net"
}),
new webpack.optimize.UglifyJsPlugin({
compress: { warnings: false },
}),
new webpack.optimize.CommonsChunkPlugin("commons", "../js/commons.min.js"),
new ExtractTextPlugin("../css/[name].min.css", {
allChunks: true
}),
]
};
我怎样才能做到这一点?我尝试过使用公开模块,但从未成功。谢谢!
答
我会重写为答案。作为Webpack配置的JavaScript的一部分,你可以做很多事情来改进,但我会试着专注于这个问题。

使用模块
import App from '../app.js'; var Layout = function() { var resBreakpointMd = App.getResponsiveBreakpoint('md'); }
和
var App = { getResponsiveBreakpoint: function(size) { var sizes = { 'xs' : 480, // extra small 'sm' : 768, // small 'md' : 992, // medium 'lg' : 1200 // large }; return sizes[size] ? sizes[size] : 0; } } export default App;
您定义
getResponsiveBreakpoint
作为函数的一员,所以它词法范围内。这样它就无法从外部访问。最简单的事情是将其转换为对象像我一样在上面的代码
取决于你想要达到的目标,你也可以把它的功能的静态成员是这样:
var App = function() {
// some logic here
}
App.getResponsiveBreakpoint: function(size) {
var sizes = {
'xs' : 480, // extra small
'sm' : 768, // small
'md' : 992, // medium
'lg' : 1200 // large
};
return sizes[size] ? sizes[size] : 0;
}
export default App;
我希望现在有所帮助。

现在有效!非常感谢! :) –
您是否尝试从包含布局的文件中的'./从/./app/./应用程序导入应用程序?如果你不使用ES6(导入),你可以使用'var App = require('./ path/to/App /')' – Grgur
感谢您的回复,我尝试添加:var'App = require('./ js /app.js');'在layout.js顶部'然后我得到错误layout.js模块没有找到,当我添加内部布局功能,我没有找到app.js模块 –
我想象你的路径可能不是对。它应该是相对于layout.js。它可以'var App = require('../ app.js');'? – Grgur
