AngularJS-如何从控制器内部更改状态

我是AngularJS的新手，想知道如何从Controller内部更改状态.

I am new to AngularJS and would like to know how I change the State from within the Controller.

例如，我通常在单击按钮时更改状态:

For example, I typically change the state on a button click:

<input type="submit" class="btn btn-lg btn-primary btn-block" value="Log In" ui-sref="main.navigation"/>

因此，在提交"按钮上，我的页面将更改为导航页面.这可以正常工作，但是如果我想先在控制器中执行一些逻辑，然后根据结果进行操作，我想更改为特定页面该怎么办.我该如何从控制器内部执行此操作，而不是通过单击按钮进行操作.

So on Submit of the button, my page will change to the navigation page. This works fine, but what if I want to do some logic in my controller first, and then based off the results, I would want to change to a specific page. How do I do this from within the controller, versus from a button click.

这是我的modules.js，以防您好奇:

Here is my modules.js in case you are curious:

angular.module('ecsMain', [
    'ui.router',
    'ui.bootstrap',
    'ngTable'
])
.config(['$stateProvider', '$urlRouterProvider', function ($stateProvider, $urlRouterProvider) {
    $urlRouterProvider.otherwise('main/login');

    $stateProvider
        .state('main', {
            abstract: true,
            url: '',
            templateUrl: 'view/main.html'
        })
        .state('main.login', {
            url: '',
            controller: ECSMainController,
            templateUrl: 'view/login.html'
        })
        .state('main.phoneCalls', {
            url: '',
            controller: AccordionDemoCtrl,
            templateUrl: 'view/phoneCalls.html'
        })
        .state('main.navigation', {
            url: '',
            controller: ModalDemoCtrl,
            templateUrl: 'view/navigation.html'
        })
        .state('main.myModalContent', {
            url: '',
            controller: ModalDemoCtrl,
            templateUrl: 'view/myModalContent.html'
        })
        .state('main.alertMessage', {
            url: '',
            controller: ModalDemoCtrl,
            templateUrl: 'view/alertMessage.html'
        })
}]);

谢谢
