本篇文章主要介绍了详解基于angular路由的requireJs按需加载js，小编觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随小编过来看看吧
最近终于不忙了！！有时间沉淀一下之前学到的angular东东！！
angular路由想必大家已经不陌生了！（陌生的去看我之前那篇手把手教你配置angular路由！）
angular路由作为单页面应用，切换页面的时候都是一个页面，所以切换controller和按需加载控件js就成了大问题！！折腾了我半天啊，angular-route内置的办法也没有解决这个问题，最终我是用requireJs解决的这个问题！！上代码！
1.首先引入requireJs，并且在它的下面用闭包写配置 requirejs([‘framework’])，这句话的意思是首次进入页面，加载framework
2.framework.js作为首次加载的js，起到至关重要的作用哈！！定义frameworkApp模块作为主模块，另外加载公共服务utilmodel和ngRoute路由，定义一个resolveController方法，回调函数是requireJs，一会儿会讲到！
//引入模块 var frameworkApp = angular.module('Frame<i style="color:transparent">来源gaodai$ma#com搞$代*码网</i>workApp',['ngRoute', 'utilModule']); //加载对应的controller var resolveController = function (names, dependancies) { //console.log(names) //console.log(dependancies) return { loadController: ['$q', '$rootScope', function ($q, $rootScope) { var defer = $q.defer(); require(names, function () { defer.resolve(); $rootScope.$apply(); }); return defer.promise; }] }; };
3.配置路由，用resolve方法完成回调，注意回调的是一个list，值是步骤一中定义的模块名称
frameworkApp.config(['$routeProvider', '$controllerProvider', '$provide', '$compileProvider', '$filterProvider', function ($routeProvider, $controllerProvider, $provide, $compileProvider, $filterProvider) { frameworkApp.register = { controller: $controllerProvider.register, factory: $provide.factory, service: $provide.service, filter: $filterProvider.register, directive: $compileProvider.directive }; $routeProvider .when('/',{ redirectTo: '/dashboard' }) .when('/dashboard',{ templateUrl: 'dashboard.html', controller: 'DashboardCtrl', resolve: resolveController(['standardDashboard', 'd3','radialProgress','highcharts']) }) .when('/console',{ templateUrl: 'console.html', controller: 'ConsoleCtrl', resolve: resolveController(['standardConsole']) }) .when('/amountStatistic',{ templateUrl: 'amount-statistic.html', controller: 'amountStatisticCtrl', resolve: resolveController(['standardAmountStatistic','highcharts','dateTimePicker']) }) .when('/report',{ templateUrl: 'report.html', controller: 'ReportCtrl', resolve: resolveController(['standardReport','dateTimePicker']) }) .when('/advancedReport',{ templateUrl: 'advanced-report.html', controller: 'advancedReportCtrl', resolve: resolveController(['standardAdvancedReport','highcharts','dateTimePicker']) }) .when('/expertAnswer',{ templateUrl: 'expert-answer.html', controller: 'expertAnswerCtrl', resolve: resolveController(['standardExpertAnswer']) }) .when('/service',{ templateUrl: 'service.html', controller: 'ServiceCtrl', resolve: resolveController(['standardService']) }) .when('/strategy-inform',{ templateUrl: 'strategy-inform.html', controller: 'StrategyInformCtrl', resolve: resolveController(['standardStrategyInform']) }) .when('/member',{ templateUrl: 'member.html', controller: 'MemberCtrl', resolve: resolveController(['standardMember']) }) .when('/schedule',{ templateUrl: 'schedule.html', controller: 'ScheduleCtrl', resolve: resolveController(['standardSchedule']) }) .when('/channel',{ templateUrl: 'channel.html', controller: 'ChannelCtrl', resolve: resolveController(['standardChannel']) }) .when('/strategy-merge',{ templateUrl: 'strategy-merge.html', controller: 'StrategyMergeCtrl', resolve: resolveController(['standardStrategyMerge']) }) .when('/integrate',{ templateUrl: 'integrate.html', controller: 'IntegrateCtrl', resolve: resolveController(['standardIntegrate']) }) .when('/personalCenter',{ templateUrl: 'personal-center.html', controller: 'PersonalCenterCtrl', resolve: resolveController(['standardPersonalCenter']) }) .otherwise({ redirectTo: '/error' }); }]);
4.大功告成啦~完成controller切换，和js按需加载！！！啦啦啦！
5.有一点我也没解决，在引入echarts的时候，用这种方法就报错了，换成highcharts就可以了，折腾半天啊也没把echarts引进来，不过到是发现，在require生效之前引入echarts的话，是可以的！求大神讲解啊！！
