Javascript 从服务器加载html和控制器并创建动态状态UI-router
我正在寻找从服务器动态加载我的应用程序内容的解决方案 我的设想： 假设我们有2个用户（A和B），我的应用程序由不同的模块组成，比如购物清单和计算器，现在我的目标是用户从数据库登录到我的应用程序，我获得用户权限，根据他拥有的权限，我将从服务器加载视图的html和逻辑部分的控制器文件，在这样做的同时，我将创建html和ctrl所需的状态。因此，基本上我的应用程序是非常小的登录，其他一切都是从服务器上拉取决于用户权限 我使用的是：Javascript 从服务器加载html和控制器并创建动态状态UI-router,javascript,angularjs,requirejs,angular-ui-router,oclazyload,Javascript,Angularjs,Requirejs,Angular Ui Router,Oclazyload,我正在寻找从服务器动态加载我的应用程序内容的解决方案 我的设想： 假设我们有2个用户（A和B），我的应用程序由不同的模块组成，比如购物清单和计算器，现在我的目标是用户从数据库登录到我的应用程序，我获得用户权限，根据他拥有的权限，我将从服务器加载视图的html和逻辑部分的控制器文件，在这样做的同时，我将创建html和ctrl所需的状态。因此，基本上我的应用程序是非常小的登录，其他一切都是从服务器上拉取决于用户权限 我使用的是： 科尔多瓦 安格拉斯 离子骨架 为什么我需要它充满活力： 1） 有可能有

Html控制器创建了状态
，一切似乎都很正常，只是控制器似乎根本不工作，没有错误，但似乎没有执行任何控制器逻辑。目前，从先前下载的文件中注册控制器的唯一解决方案是使用eval（），
，这与其说是一个合适的解决方案，不如说是一种黑客行为

所有应用程序逻辑都应包含在服务器上，并通过REST、SOAP或类似方式通过API调用提供服务。这样做可以减少UI中内置的逻辑量，从而减少对客户端的压力。这基本上使客户端应用程序成为一个呈现代理，只包含b服务的数据和逻辑的模型和视图AckendAPI
正如foreyez在评论中所说，这不是任何现代（或半现代）设备的问题
如果你坚持不一次加载所有的布局，你当然可以将它们分割成部分，然后根据用户权限在登录后加载。这样做，你可以减少内存中的数据量，即使这种改进充其量是值得怀疑的。我开发了一个应用程序，将这些数据保存在m中这是我的建筑
文件夹结构：
WebApp
|---CommonModule
|---common-module.js //Angular Module Defination
|---Controllers //Generally Nothing, but if you have a plan to
//extend from one CommonController logic to several
//module then it is usefull
|---Services //Common Service Call Like BaseService for all $http
//call, So no Module Specific Service will not use
//$http directly. Then you can do several common
//things in this BaseService.
//Like Error Handling,
//CSRF token Implementation,
//Encryption/Decryption of AJAX req/res etc.
|---Directives //Common Directives which you are going to use
//in different Modules
|---Filters //Common Filters
|---Templates //Templates for those common directives
|---index.jsp //Nothing, Basically Redirect to
//Login or Default Module
|---scripts.jsp //JQuery, AngularJS and Other Framworks scripts tag.
//Along with those, common controlers, services,
//directives and filtes.
|---templates.jsp //Include all common templates.
|---ng-include.jsp //will be used in templates.jsp to create angular
//template script tag.
|---ModuleA
|---moduleA-module.js //Angular Module Definition,
//Use Common Module as Sub Module
|---Controllers
|---Services
|---Directives
|---Filters
|---Templates
|---index.jsp
|---scripts.jsp
|---templates.jsp
|---ModuleB
|--- Same as above ...
注意：大写字母表示文件夹。模块a旁边会有一个用于您案例的LoginModule，我想您也可以使用CommonModule
梅胡的发言如下
<a href="/ModuleA/">Module A</a> <!--Note: index.jsp are indexed file
//for a directive -->
<a href="/ModuleB/">Module B</a>
angular.module('ModuleA.controllers', []);
angular.module('ModuleA.services', []);
angular.module('ModuleA.directives', []);
angular.module('ModuleA.filters', []);
angular.module('ModuleA',
['Common',
'ModuleA.controllers' ,
'ModuleA.services' ,
'ModuleA.directives' ,
'ModuleA.filters'])
.config(['$routeProvider', function($routeProvider) {
//$routeProvider state setup
}])
.run (function () {
});
我可以建议您更改加载状态的方式吗？
编写一个脚本，返回一个json，其中包含用户可以访问的状态。
例如
资源/路由配置.yourLangage？user=user-id-12345
这将返回一个json文件，该文件取决于登录的用户。结构可以如下所示：
[
{
"name": "home",
"url": "/home",
"templateUrl": "views/home.html",
"controller": "HomeController",
"dependencies": ["scripts/home/controllers.js", "scripts/home/services.js", "scripts/home/directives.js"]
},
{
"name": "user",
"url": "/user",
"templateUrl": "views/user.html",
"controller": "UserController",
"dependencies": ["scripts/user/controllers.js", "scripts/user/services.js", "scripts/home/directives.js"]
}
]
然后，让我们编写一个服务来读取允许用户访问的状态：
app.factory('routingConfig', ['$resource',
function ($resource) {
return $resource('resources/routing-config.yourLangage', {}, {
query: {method: 'GET',
params: {},
isArray: true,
transformResponse: function (data) {
// before that we give the states data to the app, let's load all the dependencies
var states = [];
angular.forEach(angular.fromJson(data), function(value, key) {
value.resolve = {
deps: ['$q', '$rootScope', function($q, $rootScope){
// this will be resolved only when the user will go to the relative state defined in the var value
var deferred = $q.defer();
/*
now we need to load the dependencies. I use the script.js javascript loader to load the dependencies for each page.
It is very small and easy to be used
http://www.dustindiaz.com/scriptjs
*/
$script(value.dependencies, function(){ //here we will load what is defined in the dependencies field. ex: "dependencies": ["scripts/user/controllers.js", "scripts/user/services.js", "scripts/home/directives.js"]
// all dependencies have now been loaded by so resolve the promise
$rootScope.$apply(function(){
deferred.resolve();
});
});
return deferred.promise;
}]
};
states.push(value);
});
return states;
}
}
});
}]);
然后，让我们配置应用程序：
app.config(['$stateProvider', '$urlRouterProvider', '$locationProvider', '$filterProvider', '$provide', '$compileProvider',
function ($stateProvider, $urlRouterProvider, $locationProvider, $filterProvider, $provide, $compileProvider) {
// this will be the default state where to go as far as the states aren't loaded
var loading = {
name: 'loading',
url: '/loading',
templateUrl: '/views/loading.html',
controller: 'LoadingController'
};
// if the user ask for a page that he cannot access
var _404 = {
name: '_404',
url: '/404',
templateUrl: 'views/404.html',
controller: '404Controller'
};
$stateProvider
.state(loading)
.state(_404);
// save a reference to all of the providers to register everything lazily
$stateProviderRef = $stateProvider;
$urlRouterProviderRef = $urlRouterProvider;
$controllerProviderRef = $controllerProvider;
$filterProviderRef = $filterProvider;
$provideRef = $provide;
$compileProviderRef = $compileProvider;
//redirect the not found urls
$urlRouterProvider.otherwise('/404');
}]);
现在让我们在应用程序中使用此服务。运行：
app.run(function ($location, $rootScope, $state, $q, routingConfig) {
// We need to attach a promise to the rootScope. This will tell us when all of the states are loaded.
var myDeferredObj = $q.defer();
$rootScope.promiseRoutingConfigEnd = myDeferredObj.promise;
// Query the config file
var remoteStates = routingConfig.query(function() {
angular.forEach(remoteStates, function(value, key) {
// the state becomes the value
$stateProviderRef.state(value);
});
// resolve the promise.
myDeferredObj.resolve();
});
//redirect to the loading page until all of the states are completely loaded and store the original path requested
$rootScope.myPath = $location.path();
$location.path('/loading'); //and then (in the loading controller) we will redirect to the right state
//check for routing errors
$rootScope.$on('$stateChangeError',
function(event, toState, toParams, fromState, fromParams, error){
console.log.bind(console);
});
$rootScope.$on('$stateNotFound',
function(event, unfoundState, fromState, fromParams){
console.error(unfoundState.to); // "lazy.state"
console.error(unfoundState.toParams); // {a:1, b:2}
console.error(unfoundState.options); // {inherit:false} + default options
});
});
最后，LoadingController：
app.controller('LoadingController', ['$scope', '$location', '$rootScope',
function($scope, $location, $rootScope) {
//when all of the states are loaded, redirect to the requested state
$rootScope.promiseRoutingConfigEnd.then(function(){
//if the user requested the page /loading then redirect him to the home page
if($rootScope.myPath === '/loading'){
$rootScope.myPath = '/home';
}
$location.path($rootScope.myPath);
});
}]);
通过这种方式，一切都是超级灵活和惰性加载的
