在angularJs中更改$ scope变量值

Question

I have three buttons here wish to make $scope. -> q <- $scope. -> q <- q as variable. How can I achieve that. This is just a test code my actual problem is based on making q as variable so please do not suggest any workaround

 var app = angular.module('myApp', []); app.controller('myCtrl', function($scope) { $scope.name = function(q){ $scope.a = "John Doe "; // $scope.q how to make q varibale } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app="myApp" ng-controller="myCtrl"> Name: <button ng-click="name('a')" ng-model="name">this is a</button> <button ng-click="name('b')" ng-model="name">this is b</button> <button ng-click="name('c')" ng-model="name">this is c</button> {{a}} via a<br> {{b}} via b<br> {{c}} via c<br> </div>

Just add q as a key to scope because $scope in nature is an object

 var app = angular.module('myApp', []); app.controller('myCtrl', function($scope) { $scope.name = function(q){ $scope[q] = "John Doe "; // $scope.q how to make q varibale } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app="myApp" ng-controller="myCtrl"> Name: <button ng-click="name('a')" ng-model="name">this is a</button> <button ng-click="name('b')" ng-model="name">this is b</button> <button ng-click="name('c')" ng-model="name">this is c</button> {{a}} via a<br> {{b}} via b<br> {{c}} via c<br> </div>

 var app = angular.module('myApp', []); app.controller('myCtrl', function($scope) { $scope.name = function(q){ $scope[q] = "John Doe "+ q; // $scope.q how to make q varibale } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app="myApp" ng-controller="myCtrl"> Name: <button ng-click="name('a')" ng-model="name">this is a</button> <button ng-click="name('b')" ng-model="name">this is b</button> <button ng-click="name('c')" ng-model="name">this is c</button> {{a}} via a<br> {{b}} via b<br> {{c}} via c<br> </div>
