Angularjs - how to shuffle the class names using the scope function? -

-

i have 3 elements, shows conditional. on click of them using 'ng-class' showing or hiding element.

here html :

<div class="useroptions">         <div class="row designoption" ng-class="{'active':prodesign}">             <span ng-click="categories('prodesign')" class="icon icond">d</span>             <span class="info infod">design</span>         </div>         <div class="row suplyoption" ng-class="{'active':supply}">             <span ng-click="categories('prosupply')" class="icon icons">s</span>             <span class="info infos">supply</span>         </div>         <div class="row constoption" ng-class="{'active':construct}">             <span ng-click="categories('proconstruct')" class="icon iconc">c</span>             <span class="info infoc">construction</span>         </div>     </div>

but using scope function not able shuffle class name active. here try:

$scope.prodesign = false;             $scope.proconstruct = false;             $scope.prosupply = false;              $scope.categories = function (categ) {                  $scope.prodesign = false; //all false.                 $scope.proconstruct = false;                 $scope.prosupply = false;                  $scope[categ] = !$scope[categ]; //became true             }

but not working. if so, correct way this?
