vue+vuecli+webapck2實現多頁面應用

準備工作

在本地用vue-cli新建一個項目，首先安裝vue-cil，命令：

npm install -g vue-cli

新建一個vue項目,創建一個基于"webpack"的項目,項目名為vuedemo：

vue init webpack vuedemo

這里有一個地方需要改一下，在執行npm install命令之前，在package.json里添加一個依賴,后面會用到。

修改webpack配置

在這一步里我們需要改動的文件都在build文件下，分別是：

utils.js
webpack.base.conf.js
webpack.dev.conf.js
webpack.prod.conf.js

utils.js文件

// utils.js文件var path = require('path')
var config = require('../config')
var ExtractTextPlugin = require('extract-text-webpack-plugin')exports.assetsPath = function (_path) {var assetsSubDirectory = process.env.NODE_ENV === 'production' ?config.build.assetsSubDirectory :config.dev.assetsSubDirectoryreturn path.posix.join(assetsSubDirectory, _path)
}exports.cssLoaders = function (options) {options = options || {}var cssLoader = {loader: 'css-loader',options: {minimize: process.env.NODE_ENV === 'production',sourceMap: options.sourceMap}}// generate loader string to be used with extract text pluginfunction generateLoaders(loader, loaderOptions) {var loaders = [cssLoader]if (loader) {loaders.push({loader: loader + '-loader',options: Object.assign({}, loaderOptions, {sourceMap: options.sourceMap})})}// Extract CSS when that option is specified// (which is the case during production build)if (options.extract) {return ExtractTextPlugin.extract({use: loaders,fallback: 'vue-style-loader'})} else {return ['vue-style-loader'].concat(loaders)}}// https://vue-loader.vuejs.org/en/configurations/extract-css.htmlreturn {css: generateLoaders(),postcss: generateLoaders(),less: generateLoaders('less'),sass: generateLoaders('sass', { indentedSyntax: true }),scss: generateLoaders('sass'),stylus: generateLoaders('stylus'),styl: generateLoaders('stylus')}
}// Generate loaders for standalone style files (outside of .vue)
exports.styleLoaders = function (options) {var output = []var loaders = exports.cssLoaders(options)for (var extension in loaders) {var loader = loaders[extension]output.push({test: new RegExp('\\.' + extension + '$'),use: loader})}return output
}/* 這里是添加的部分 ---------------------------- 開始 */// glob是webpack安裝時依賴的一個第三方模塊，還模塊允許你使用 *等符號, 例如lib/*.js就是獲取lib文件夾下的所有js后綴名的文件
var glob = require('glob')
// 頁面模板

// 取得相應的頁面路徑，因為之前的配置，所以是src文件夾下的pages文件夾
var PAGE_PATH = path.resolve(__dirname, '../src/pages')
// 用于做相應的merge處理
var merge = require('webpack-merge')//多入口配置
// 通過glob模塊讀取pages文件夾下的所有對應文件夾下的js后綴文件，如果該文件存在
// 那么就作為入口處理
exports.entries = function () {var entryFiles = glob.sync(PAGE_PATH + '/*/*.js')var map = {}entryFiles.forEach((filePath) => {var filename = filePath.substring(filePath.lastIndexOf('\/') + 1, filePath.lastIndexOf('.'))map[filename] = filePath})return map
}//多頁面輸出配置
// 與上面的多頁面入口配置相同，讀取pages文件夾下的對應的html后綴文件，然后放入數組中
exports.htmlPlugin = function () {let entryHtml = glob.sync(PAGE_PATH + '/*/*.html')let arr = []entryHtml.forEach((filePath) => {let filename = filePath.substring(filePath.lastIndexOf('\/') + 1, filePath.lastIndexOf('.'))let conf = {// 模板來源template: filePath,// 文件名稱filename: filename + '.html',// 頁面模板需要加對應的js腳本，如果不加這行則每個頁面都會引入所有的js腳本chunks: ['manifest', 'vendor', filename],inject: true}if (process.env.NODE_ENV === 'production') {conf = merge(conf, {minify: {removeComments: true,collapseWhitespace: true,removeAttributeQuotes: true},chunksSortMode: 'dependency'})}arr.push(new HtmlWebpackPlugin(conf))})return arr
}
/* 這里是添加的部分 ---------------------------- 結束 */

webpack.base.conf.js 文件

// webpack.base.conf.js 文件var path = require('path')
var utils = require('./utils')
var config = require('../config')
var vueLoaderConfig = require('./vue-loader.conf')function resolve(dir) {return path.join(__dirname, '..', dir)

}

webpack.dev.conf.js 文件

var utils = require('./utils')
var webpack = require('webpack')
var config = require('../config')
var merge = require('webpack-merge')
var baseWebpackConfig = require('./webpack.base.conf')
var HtmlWebpackPlugin = require('html-webpack-plugin')

})

webpack.prod.conf.js 文件

var path = require('path')
var utils = require('./utils')
var webpack = require('webpack')
var config = require('../config')
var merge = require('webpack-merge')

}if (config.build.bundleAnalyzerReport) {var BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPluginwebpackConfig.plugins.push(new BundleAnalyzerPlugin())
}module.exports = webpackConfig

至此，webpack的配置就結束了。

src就是我所使用的工程文件了，assets,components,pages分別是靜態資源文件、組件文件、頁面文件。

原先，入口文件只有一個main.js,但現在由于是多頁面，因此入口頁面多了，我目前就是兩個：index和cell，之后如果打包，就會在dist文件下生成兩個HTML文件：index.html和cell.html(可以參考一下單頁面應用時，打包只會生成一個index.html,區別在這里)。

頁面跳轉問題

既然是多頁面，肯定涉及頁面之間的互相跳轉，就按照我這個項目舉例，從index.html文件點擊a標簽跳轉到cell.html。

一般都認為這樣寫：

 <!-- index.html -->
<a href='../cell/cell.html'></a>

但這樣寫，不論是在開發環境還是最后測試，都會報404，找不到這個頁面。

改成這樣既可：

 <!-- index.html -->
<a href='cell.html'></a>

如果想跳轉到另外一個路由配置的某個模塊，如賬號中心，如下例子：

<a class="home_account" href="login.html#/inner/acount/acountCenter">{{userInfo.phone}}</a>
