Toggle class with ng-click on several elements

I made simple directive for testing:

module.directive('toggleClass', function() {    return {        restrict: 'A',        link: function(scope, element, attrs) {            element.bind('click', function() {                element.toggleClass(attrs.toggleClass);            });        }    };});

so you can make any element toggle class you need

<button id="btn" toggle-class="active">Change Class</button><div toggle-class="whatever"></div>

Depending on your requirements, you may be able to use an ng-repeat with an array representing the toggles. For example:

Your view:

<div ng-repeat="toggle in toggles">    <button id="btn" ng-click="toggle.state = !toggle.state" ng-class="{'red' : toggle.state}">Change Class</button></div>

Inside your controller:

$scope.toggles = [{ state: true }, { state: false }, { state: true }];

This way you can expand on your button set by simply updating the array, or the internal array objects (should you need more complexity).

inside controller

 $scope.stateToggle=false;$scope.togglelasses=function(){     $scope.stateToggle= !$scope.stateToggle;}

in view use ng-class

 <button ng-click="togglelasses()" ng-class="stateToggle? 'active ': ' '">

add ng-class in every element where you want class active
