AngularJS Question

AngularJS - How do I change the State from Inside the Controller

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

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"/>


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.

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'
})
}]);


Thanks

Answer

inject $state service to your controller, then in your controller...

CONTROLLER

$scope.changeState = function () {
    $state.go('where.ever.you.want.to.go', {stateParamKey: exampleParam});
};

and add ng-click to your button

HTML

<button ng-click="changeState()">Change State</button>
