Question

Can my angular controller determine the specific ui-view it is residing in using ui-router?

I am currently working on a project using ui-router with angularjs. My goal is to create a template for a view that will display an image based on the specific view it is associated with. Below, I have provided an example state:

$stateProvider
    .state('index', {
        url: "",
        views: {

             "topStormtrooper": { 
                templateUrl: '/components/stormtroopers/stormtroopers.html',
                controller: "stormtroopersCtrl"
            },

             "bottomStormtrooper": { 
                templateUrl: '/components/stormtroopers/stormtroopers.html',
                controller: "stormtroopersCtrl"
            }
        }
    })

My controller code is as follows:

.controller('stormtroopersCtrl', ['$scope', '$http', '$stateParams', function ($scope, $http, $stateParams) {
//   
$scope.stormtrooper = $stateView; //I hope this works

}]);

Although the template remains the same, the image displayed should vary depending on the view it is loaded into. Currently, I have created separate controllers for each view and load the corresponding image. However, I believe it should be possible to achieve this using just one controller that can detect the specific view. While I am aware that you can identify the state, I am seeking a way to delve deeper and identify the view.

Any suggestions or ideas?

If you need to monitor the $viewContentLoaded function within your controller, you can refer to the details provided in the ui-router documentation

Here is an example of how you can achieve this:

.controller('rebelTroopersCtrl', ['$scope', '$http', '$stateParams', function ($scope, $http, $stateParams) {

$scope.$on("$viewContentLoaded",function(event,viewName){ //keep track of content loading into the view
    $scope.currentView = viewName;  //store the view name in a variable
    console.log($scope.currentView);
    //perform actions based on the retrieved view name....

});

}]);

Don't go through the hassle of changing your state just to modify an image in the template. Use scope variables instead.

angular.module('app',[])
.controller('stormtrooperCtrl', ['$scope', function ($scope) {
//   
  $scope.selected = 0;
  $scope.images = [
    "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSz6dBOOsFVAeSilVEIO9dqwrY4R5gCzEMcrRVZguhYhr9PVJsThQ",
    "http://www.wallpapereast.com/static/images/Wallpaper-Nature-8B71.jpg",
    "http://www.intrawallpaper.com/static/images/1250654-for-laptop-nature.jpg"
  ];


}]);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.22/angular.min.js"></script>
<div ng-app="app">
  <div ng-controller="stormtrooperCtrl">
  <button ng-click="selected=0">image1</button>
  <button ng-click="selected=1">image2</button>
  <button ng-click="selected=2">image3</button>
    <div>
      <img width="100" ng-src="{{images[selected]}}"/>
    </div>
  </div>
</div>
