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+$oclazyLoad实现动态加载。
1.webpack
webpack.config.js
var path = require('path');
var webpack = require('webpack');
var ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = {
entry: {
home: [
'babel-polyfill',
'./app/app.js' //引入文件
],
common: [
'babel-polyfill',
'angular',
'angular-ui-router',
'oclazyload'
]
},
output: {
path: path.join(__dirname, '/wap'),
filename: '[name].js',
chunkFilename: '[id].build.js&＃63;[chunkhash]',
publicPath: '/wap/',
},
module: {
loaders: [
{
test:/\.js&＃63;$/,
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 = "footer"
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';
$scope.isshow = false;
}
}
export default class header {
constructor() {
this.restrict = 'E',
this.scope = {},
this.template = require(./header.html)
this.cOntroller= Header
this.link = (scope, element, attr) => {}
}
}
header/header.html
4.home
home/index.js
import angular from "angular";
import HomeController from './controller';
export default angular.module('app_home',[])
.controller('HomeController', HomeController)
home/controller.js
export default class HomeController {
constructor($scope) {
'ngInject';
this.isshow = false;
this.eage = 'sds';
$scope.edg = 'sma'
}
change(){
this.isshow = !this.isshow;
console.log(this.isshow);
}
}
home/home.html
home {{HMC.eage}} -- {{edg}}
其余的模块大同小异就不依依去写了。
