这是状态配置:
angular .module('grabhutApp ',[...]) .config(函数($ stateProvider,$ urlRouterProvider){ $ stateProvider // ACCOUNT .state('account ',{ abstract:true, url:'/ account', templateUrl:'index.html'}) .state('account.main ',{ url:'', templateUrl:'views / account / account.login.html', controller:'AccountController'})。 。。 // NO VIEWS .state('nv',{ abstract:true, url:'/ nv'}) .state('nv.logout',{ url:'/ logout'}) });nv 及其子州将有没有物理视图或控制器。 我希望它们作为调用某些功能的链接。
呼叫退出方法的服务:
angular.module('grabhutApp') .factory('$ grabhutAccountService',function($ state,$ grabhutDataService){ var methods = {。。 logoutUser:function(){ $ grabhutDataService.user.removeSession(); $ state.go('account.main',{},{location:'replace' }); } 。。}; 返回方法; });然后是退出的按钮/链接:
< a ui-sref =nv.logoutclass =button icon icon ion-log-out button-largemenu-close>< ; / A>我希望发生的是,当州 nv.logout 被触发了$ $ grabhutAccountService.logoutUser()必须被调用,并且必须重定向到'帐户。 main'
这是我到目前为止所做的: 我试图在 nv.logout
.state('nv。注销',{ url:'/ logout', resolve:{ logout:function($ grabhutAccountService){ $ grabhutAccountService.logoutUser(); } } })服务已被调用但状态未重定向。所以我尝试了另一种方式。我添加了一个控制器:
.state('nv.logout',{ url:'/ logout', resolve:{ logout:function($ grabhutAccountService){ $ grabhutAccountService.logoutUser(); } }, controller:function($范围,$ state){ $ scope。$ on('$ stateChangeSuccess',function(){ $ state.go('account.main'); }); } })但是 $ stateChangeSuccess 没有被解雇。 所以我尝试使用rootScope:
.run(function(....,$ grabhutAccountService){ 。。。 $ rootScope.logout = function() { $ grabhutAccountService.logoutUser(); }; 。。。 })使用它如下:
<一个ng-click =$ root.logout()class =button icon icon ion-log-out button-largemenu-close>< / a>
这很好用。但是我很担心,因为(AFAIK)rootScope会加载更多可能导致操作速度变慢的数据。 此外,每当我需要某种类似上面的函数时,我都必须再次在rootScope中附加函数。 > 我认为这不是一个好方法。顺便说一句,我在手机屏幕中构建这个,这就是内存使用如此重要的原因。
解决方案哦,你真是太近了。我重新安排了你的一些代码并得出了这个:
app.run(function($ rootScope,$ grabhutAccountService){ $ rootScope。$ on('$ stateChangeSuccess',function(evt,toState){ if(toState.name ==='nv.logout'){ $ grabhutAccountService.logoutUser(); $ state.go('account.main'); } }); });UI-Router的下一个主要版本将有很多改进的钩子用于做这类事情。 / p>
This is the state configuration:
angular .module('grabhutApp', [...]) .config(function ($stateProvider, $urlRouterProvider) { $stateProvider // ACCOUNT .state('account', { abstract: true, url: '/account', templateUrl: 'index.html' }) .state('account.main', { url: '', templateUrl: 'views/account/account.login.html', controller: 'AccountController' }) . . . // NO VIEWS .state('nv', { abstract: true, url: '/nv' }) .state('nv.logout', { url: '/logout' }) });The nv and its sub states will have no physical views or controllers. I want them to serve as links that calls certain functions.
Service for calling logout methods:
angular.module('grabhutApp') .factory('$grabhutAccountService', function ($state, $grabhutDataService) { var methods = { . . logoutUser: function () { $grabhutDataService.user.removeSession(); $state.go('account.main', {}, {location: 'replace'}); } . . }; return methods; });Then a button/link for logout:
<a ui-sref="nv.logout" class="button icon icon ion-log-out button-large" menu-close></a>What I want to happen is that, when state nv.logout was triggered the $grabhutAccountService.logoutUser() must be called and must redirect to 'account.main'
Here is what I've done so far: I tried to use resolve in nv.logout
.state('nv.logout', { url: '/logout', resolve: { logout: function ($grabhutAccountService) { $grabhutAccountService.logoutUser(); } } })The service was called but state did not redirect. So I tried another way. I added a controller:
.state('nv.logout', { url: '/logout', resolve: { logout: function ($grabhutAccountService) { $grabhutAccountService.logoutUser(); } }, controller: function ($scope, $state) { $scope.$on('$stateChangeSuccess', function () { $state.go('account.main'); }); } })But $stateChangeSuccess is not being fired. So I tried to use the rootScope:
.run(function(...., $grabhutAccountService){ . . . $rootScope.logout = function(){ $grabhutAccountService.logoutUser(); }; . . . })And the use it like this:
<a ng-click="$root.logout()" class="button icon icon ion-log-out button-large" menu-close></a>
This works fine. But I'm worrying since (AFAIK) rootScope loads more data which could cause slower operation. Besides, whenever I need some kind of function like above, I would have to attach function in rootScope again. And I think that's not a good approach. BTW, I'm building this in phonegap that's why memory usage is so important.
解决方案Ooooh you're so close. I rearranged some of your code and arrived at this:
app.run(function($rootScope, $grabhutAccountService) { $rootScope.$on('$stateChangeSuccess', function (evt, toState) { if (toState.name === 'nv.logout') { $grabhutAccountService.logoutUser(); $state.go('account.main'); } }); });The next major version of UI-Router will have much improved hooks for doing this sort of thing.
