虽然，现在越来越多的人选择使用react、vue以及ng2，但是依然存在相当一部分人在使用angular1.x开发。本文将介绍如何使用webpack+es6+angular1.x+$oclazyLoad实现动态加载。

1.webpack

webpack.config.js

var path = require('path');var webpack = require('webpack');var ExtractTextPlugin = require("extract-text-webpack-plugin");module.exports = { entry: { home: [ 'babel-polyfill', './app/app.js' //引入文件 ], common: [ 'babel-polyfill', 'angular', 'angular-ui-router', 'oclazyload' ] }, output: { path: path.join(__dirname, '/wap'), filename: '[name].js', chunkFilename: '[id].build.js?[chunkhash]', publicPath: '/wap/', }, module: { loaders: [ { test:/\.js?$/, loader:'ng-annotate-loader!babel-loader', exclude:/node_modules/ }, { test: /\.html$/, loader: 'raw-loader', exclude: /node_modules/ }, ] }, resolve: { root: ['node_modules'], extensions: ['', '.js', '.html', '.json'], modulesDirectories: ['node_modules'], alias: {} }, externals: {}, plugins: [ new webpack.HotModuleReplacementPlugin(), new ExtractTextPlugin('[name].[contenthash:20].css'), new webpack.optimize.UglifyJsPlugin({ compress: {warnings: false}, sourceMap: true }), new webpack.optimize.CommonsChunkPlugin('common', 'common.js') ]}

2.Module

第一步，先引入angular ，以及相关模块，然后像es5中那样定义一个模块

app.js

import angular from 'angular';import uirouter from 'angular-ui-router';import ocLazyLoad from 'oclazyLoad';angular.module('app',[ uirouter，ocLazyLoad ])

模块与模块之间引用

我们建立第二个模块 header/index.js

import angularfrom 'angular';export default angular.module('header',[]).name

修改app.js

import header from './header'angular.module('app',[ uirouter，ocLazyLoad , header])

模块的引用完成

3.控制器

假设在header目录下新增一个控制器

header/controller.js

export default class HeaderController { consturctor(){ this.home = 'header' }}

引用控制器 修改 header/index.js

import HeaderController from './controller'export default angular.module('header',[ ]) .controller('HeaderController',HeaderController) .name

4.服务

如果要在控制器内使用$scope,或者其他服务肯定是报错的,那是因为我们在使用之前没有注入服务

所以第一步应该注入服务

header/controller.js

export default class HeaderController { consturctor($scope){ this.home = 'header' $scope.component = 'head' }}HeaderController.$inject = ['$scope']

那么如何自定义服务呢？

新建 header.server.js

class HeaderServices { constructor(){ this.name = 'cxh' } getName(){ return this.name }}

header/index.js

import HeaderService from './service';export default angular.module('header',[ ]) .controller('HeaderController',HeaderController) .service('HeaderService',HeaderService) .name

在控制器中使用自定义服务

header/controller.js

export default class HeaderController { consturctor($scope,HeaderService){ this.home = 'header' $scope.component = 'head' $scope.name = HeaderService.getName }}HeaderController.$inject = ['$scope','HeaderService']

5.指令

新建 footer/index.js 大致和 header/index.js相同

将 footer模块 引入到 app.js

新建footer/directive.js

export default class Footer { constructor(){ this.restrict = 'E', this.scope = {}, this.template = "<div ng-click='alert()'>footer</div>" this.controller = Foot this.link = (scope, element, attr) => {} }}class Foot{ constructor(){ $scope.alert = () => { alert(1) } }}Header.$inject = ['$scope']

footer/index.js

export default angular.module('footer',[]).directive('footerDirective',()=> new Footer).name

6.路由

router.js

export default router ($stateProvider, $urlRouterProvider) { $stateProvider.state("home",{ url:"/home", templateUrl:'app/home/home.html', controller: "HomeController", controllerAs:"HMC", }) $urlRouterProvider.otherwise('/home');}router.$inject = [ '$stateProvider', '$urlRouterProvider']

DEMO 实现动态加载

1.第一步，新建app.js创建一个module

import angular from 'angular';import uirouter from 'angular-ui-router';import ocLazyLoad from 'oclazyLoad';//引用创建头部 组件import Header from './header';//路由import routing from "./router.js";//引入两个子模块import Home from "./homes";import Router from "./router";angular.module('app',[uirouter, Header, ocLazyLoad, Home, Router]).config(routing)

2.配置路由 ./route.js

export default function routing($stateProvider, $urlRouterProvider) { 'ngInject'; //注入服务 就不需要使用$inject了 $stateProvider .state("home",{ url:"/home", templateProvider: ($q) => { //动态引入html模板 'ngInject'; let deferred = $q.defer(); require.ensure([], function () { let template = require('./home/home.html'); deferred.resolve(template); }); return deferred.promise; }, controller: "HomeController", controllerAs:"HMC", resolve: { //动态加载模块 loadMyCtrl: function ($q, $ocLazyLoad) { 'ngInject'; let deferred = $q.defer(); require.ensure([], () => { let module = require("./home").default; $ocLazyLoad.load({name: module.name}); deferred.resolve(module.controller) }); return deferred.promise; } } }), .state("route",{ url:"/route", templateProvider: ($q) => { //动态引入html模板 'ngInject'; let deferred = $q.defer(); require.ensure([], function () { let template = require('./router/router.html'); deferred.resolve(template); }); return deferred.promise; }, controller: "routerController", controllerAs:"RTC", resolve: { //动态加载模块 loadMyCtrl: function ($q, $ocLazyLoad) { 'ngInject'; let deferred = $q.defer(); require.ensure([], () => { let module = require("./router").default; $ocLazyLoad.load({name: module.name}); deferred.resolve(module.controller) }); return deferred.promise; } } }）$urlRouterProvider.otherwise('/home');}

3.header

header/index.js

import angular from "angular";import header from './directive';export default angular.module('app_header',[]) .directive('header', () => new header) .name;

header/directive.js

class Header { constructor($scope){ 'ngInject'; $scope.isshow = false; }}export default class header { constructor() { this.restrict = 'E', this.scope = {}, this.template = require(./header.html) this.controller = Header this.link = (scope, element, attr) => {} }}

header/header.html

<div> <a href="#home" rel="external nofollow" >home</a> <a href="#router" rel="external nofollow" >router</a></div>

4.home

home/index.js

import angular from "angular";import HomeController from './controller';export default angular.module('app_home',[]) .controller('HomeController', HomeController)

home/controller.js

export default class HomeController { constructor($scope) { 'ngInject'; this.isshow = false; this.eage = 'sds'; $scope.edg = 'sma' } change(){ this.isshow = !this.isshow; console.log(this.isshow); }}

home/home.html

<div>home {{HMC.eage}} -- {{edg}}</div>

其余的模块大同小异就不依依去写了。
