一网友写的AngularJs按需加载代码，但未验证，放着备用。
application.config( function($routeProvider) { $routeProvider. when('/:module/:view', { templateUrl: function(params) { var core = angular.element(document).injector().get('core'); core.openView(params.module, params.view); return 'app/views/{0}/{1}.jsp'.format(params.module, params.view); } }). otherwise({ redirectTo: '/home/landing' }); }); 'use strict'; // declare an application core module var coreModule = angular.module('core', ['network']); coreModule.factory('core', function (http, $location) { return { openView: function (module, view) { if (!module) { throw new Error('Please provide module.'); } if (!view) { throw new Error('Please provide view.'); } http.getController(module, view); if($location.path() !== '/{0}/{1}'.format(module, view)) { $location.path('/{0}/{1}'.format(module, view)).replace(); } } }; } ); 'use strict'; // declare a network service module var httpModule = angular.module('network', []); httpModule.factory('http', function ($http, $q) { return { get: function (url) { if (!url) { throw new Error('Please provide request url.'); } var defer = $q.defer(); $http.get(url).then( function(response) { defer.resolve(response.data); }, function(error) { defer.reject(error); }); return defer.promise; }, post: function (url, paramObj) { if (!url) { throw new Error('Please provide request url.'); } var defer = $q.defer(); paramObj = paramObj || {}; $http.post(url, paramObj).then( function(response) { defer.resolve(response.data); }, function(error) { defer.reject(error); }); return defer.promise; }, getController: function (module, controller) { if (!module) { throw new Error('Please provide module.'); } if (!controller) { throw new Error('Please provide controller.'); } var webRoot = window.location.href.substr(0, window.location.href.lastIndexOf('/home.action')); var url = '{0}/{1}/{2}/{3}.js'.format(webRoot, 'app/controllers', module, controller); var existed = false; $.each($('head').find('script'), function(index, value) { if(value.src === url) { existed = true; } }); if(!existed) { var script = document.createElement('script'); script.type = 'text/javascript'; script.src = url; script.charset = 'utf-8'; document.head.appendChild(script); } } }; } );
