Apply Ng-class Only On The Element That Was Clicked On

I want to apply the ng-class only on the button/element that was clicked on, how would I do that? JS file: var classApp = angular.module('classApp', []); classApp.controller('cla

Solution 1:

Here comes the uses of Angular Directives. Instead of maintaining various variables, you can use a simple directive:

app.directive('clickActive', [function() {
    return {
        restrict: 'A',
        link: function(scope, element, attr) {
            element.on('click', function() {
                element.toggleClass("active");
                if (attr.moreClasses) {
                    // Optionally toggle more classes if passed
                    element.toggleClass(attr.moreClasses);
                }
            });
        }
    };
}]);

HTML:

<div ng-app="classApp" ng-controller="classCtrl">
  <button class="button" click-active type="button">Click Meto Toggle Class</button> 

   <button class="button" click-active type="button">Click Meto Toggle Class</button> 
</div>

Optionally, pass more classes to toggle like:

<button class="button" click-active more-classes="foo bar" type="button">Click Meto Toggle Class</button> 

Solution 2:

Here is a possible solution:

The controller:

classApp.controller('classCtrl', function ($scope) {
    $scope.isActive = [false, false];

    $scope.activeButton = function (index) {     
        $scope.isActive[index] = !$scope.isActive[index];         
    }   
});

And the html:

<div ng-app="classApp" ng-controller="classCtrl">
    <button class="button" ng-class="{'active': isActive[0]}" ng-click="activeButton(0)" type="button">Click Meto Toggle Class</button> 

    <button class="button" ng-class="{'active': isActive[1]}" ng-click="activeButton(1)" type="button">Click Meto Toggle Class</button> 
</div>

EDIT: My solution works but @Shashank Agrawal solution is better and cleaner.
