如何在AngularJS（单页应用程序）中延迟加载JS文件？

示例：

var dashBoardModule = angular.module(
    'dashBoardApp',[ 'ui.router', 'ui.calendar', 'ngTagsInput','ui.sortable', 'chart.js','ngFileUpload', 'ngDialog', 'timer', 'datatables' ,'daterangepicker'])

 .directive('focusMe', function($timeout, $parse) {
})
.directive('schrollBottom', function () {
})

.service('Taskservice', function() {

})
.service('UserService', function($http) {

})


dashBoardModule.controller('dashBoardController', function($scope,Taskservice, $http, $state, ngDialog, $window,$timeout,GloabalVariable) {
});


dashBoardModule.controller('adminDashboardController', [ '$scope', '$http', '$state', 'allProjectsStatusData', 'uiCalendarConfig', '$compile', '$timeout', 'ngDialog',
} ]);

dashBoardModule.controller('CalendarController', [ '$scope', '$http', '$state', 'tasksData', 'uiCalendarConfig', '$compile', '$timeout', 'ngDialog',

dashBoardModule.controller('MapResourceController', [ '$scope', '$http', '$window', '$state', 'myMapResourcesData', 'ngDialog', function($scope, $http, $window, $state, myMapResourcesData, ngDialog) {

} ]);

dashBoardModule.controller('CreateProjectController', [ '$scope', '$http', 'ngDialog','$state', function($scope, $http,$state, ngDialog) {

} ]);

dashBoardModule.controller('TasksController', [

dashBoardModule.controller('ReportController', [ '$scope', '$http', 'projectsStatusData', function($scope, $http, projectsStatusData) {

} ]);


dashBoardModule.controller('CompletedTasksController', [

dashBoardModule.controller('MyTasksController', [ '$scope', '$http', '$window', 'myTasksData', 'Upload', 'ngDialog','GloabalVariable', function($scope, $http, $window, myTasksData, Upload, ngDialog,GloabalVariable) {

} ]);

dashBoardModule.controller('AddNewResourceController', [ '$scope', '$http', '$state', 'allTechnologiesData', 'ngDialog', function($scope, $http, $state, allTechnologiesData, ngDialog) {

} ]);

dashBoardModule.controller('UpdateProjectController', [ '$scope', '$http', '$state', '$stateParams', 'ngDialog', 'Upload', function($scope, $http, $state, $stateParams, ngDialog, Upload) {

} ]);

此dashboardController.js有一些服务，指令和＆amp;几个控制器根据控制器将加载少量js文件。

我想要只加载该点所需的文件！＆安培;避免遗留文件。

我该怎么做！请给我建议！

Dashboard.js看起来像这样。

每次加载所有文件......这是实惠的！

您可以使用带角度的ocLazyLoading进行延迟加载。

代表前 -

app.js

var App = angular.module('demoApp', ['$stateProvider','oc.lazyLoad']);

App.config(function($stateProvider) {
$stateProvider.state('/', {
            url: '/',
            templateUrl: 'templateUrl',
            controller: 'DemoCtrl',
            resolve: {
                lazyLoad: ['$ocLazyLoad', function($ocLazyLoad) {
                    return $ocLazyLoad.load({
                        name: 'appName',
                        files: [
                            'www/controller/login.js',
                        ]
                    })
                }]
            }
        })
})
