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
<script src="js/lib/require.min.js"></script> <script> (function () { var jsDir = '/js/'; var jsLibDir = '/js/lib/'; var jsComponentDir = '/components/'; var paths = { angular: jsLibDir + 'angular.min', angularRoute: jsLibDir + 'angular-route.min', jquery: jsLibDir + 'jquery.min', jQueryMD5: jsLibDir + 'jquery.md5', highcharts: jsLibDir + 'highcharts', radialProgress: jsLibDir + 'radialProgress', d3: jsLibDir + 'd3.min', echarts: jsLibDir + 'echarts', framework: jsDir + 'framework', angularUtil: jsDir + 'angular-util', standardDashboard: jsDir + 'standard-dashboard', standardConsole: jsDir + 'standard-console', standardAmountStatistic: jsDir + 'standard-amount-statistic', standardReport: jsDir + 'standard-report', standardAdvancedReport: jsDir + 'standard-advanced-report', standardExpertAnswer: jsDir + 'standard-expert-answer', standardService: jsDir + 'standard-service', standardStrategyInform: jsDir + 'standard-strategy-inform', standardMember: jsDir + 'standard-member', standardSchedule: jsDir + 'standard-schedule', standardChannel: jsDir + 'standard-channel', standardStrategyMerge: jsDir + 'standard-strategy-merge', standardIntegrate: jsDir + 'standard-integrate', standardPersonalCenter: jsDir + 'standard-personal-center', dateTimePicker: jsComponentDir + 'dateTimePicker/date-time-picker', fullCalendar: jsComponentDir + 'fullCalendar/fullcalendar', moment: jsComponentDir + 'fullCalendar/moment' }; requirejs.config({ paths: paths, shim: { angular: { exports : 'angular', deps: ['jquery'] }, angularRoute: { deps: ['angular'] }, jQueryMD5: { deps: ['jquery'] } }, //urlArgs: "timeStamp=" + (new Date()).getTime() //urlArgs: 'v=1.47.1&t=20160719' }); requirejs(['framework']); }()); </script>
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('FrameworkApp',['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!!
<!-- start build --> <script src="js/lib/echarts.js"></script> <script src="js/lib/require.min.js"></script>
