是否可以手动将NG动画添加到元素中?
例如,我想在添加或删除ng-class时添加ng-enter和ng-leave.但是我还需要ng-enter-active和ng-leave-active类来让我更好地控制动画过程.
我在与Angular JS连接的页面中有两条路由.
一个页面有一个表单,您可以从中保存一些信息,当我在路由之间来回切换时,angular似乎没有请求html.
我试过做$ httpProvider.defaults.cache = false;
基本上对于一条路线我不希望Angular缓存html,对于其他路线它实际上是一件好事.
代码在这里给出:
angular.module('userAccount', ['ngRoute', 'ngAnimate'])
.config(['$routeProvider', '$locationProvider', '$httpProvider',
function ($routeProvider, $locationProvider, $httpProvider) {
//$httpProvider.defaults.cache = false;
$locationProvider.hashPrefix('');
$routeProvider
.when('/UserProfile/:action', {
reloadOnSearch: false,
cache: false,
templateUrl: function (params) {
return '/UserProfile/' + params.action;
},
controller: 'UserProfCtrl'
})
.when('/UserDashboard/:action', {
templateUrl: function (params) {
return '/UserDashboard/' + params.action;
},
controller: 'UserDashCtrl'
})
.otherwise('/UserDashboard/Index');
}])

之后,用户点击"购买"按钮,离开支付网关站点的站点.成功付款后,Payment Gateway通过在回拨URL(xyz.com/booking-success)上发送POST请求来回送用户.
现在问题是我为该回调URL配置的相应Angular页面没有打开.我在RouteProvider中配置了xyz.com/booking-success页面,但这似乎没有用.
但是,如果我直接通过浏览器打开页面xyz.com/booking-success,它将被打开.
如何处理这种情况?任何帮助将不胜感激.
我正在使用 Visual Studio Code 编写基于 jasmine 和 karma 的单元测试用例。我想知道是否有一种方法可以在 VS Code 工具本身中调试测试。
如果foo 为 false,如何将keys:定义a, b, c, bar为未定义/空/可选类型?换句话说,仅当foo 为 true时,我才需要强制使用这些属性。

y: string;
c: boolean;
bar?: { x: number; y: string; z: boolean };
