javascript - Change $scope value when a ng-click function is triggered -

i tried change $scope variable in angular js's ng-click function. angular

does not seem able that.

below code on appcontroller:

//  appcontroller.js  $scope email = "awesome@example.com";  $scope.emailinfo = "great@example.com";  //emailonclick() ng-click on dom. triggered when user click button, save email information  $scope.emailonclick = function() {      $scope.email = $scope.emailinfo;      console.log($scope.email); //this print "great@example.com".  };  console.log($scope.email); // print "awesome@example.com",   //want print "great@example.com" triggered ng-click function   //apply change.   console.log($scope.emailinfo); //this print "great@example.com". 

what miss? thought?

updated:

$scope.emailonclick function assign $scope.emailinfo value $scope.email variable.

if click in «send server» button you'll see new value has been sent in console.

(function() {    var app = angular.module("myapp", []);    app.controller("controller", ["$scope",      function($scope) {        $scope.email = "awesome@example.com";        $scope.emailinfo = "great@example.com";        $scope.emailonclick = function() {          $scope.email = $scope.emailinfo; // gets emailinfo value , assigns $scope.email.          console.log($scope.email);        }        $scope.sendtoserver = function() {          console.log($scope.email);        };        console.log($scope.email); // initial state of $scope.email printed default.        console.log($scope.emailinfo); // initial state of $scope.emailinfo printed default.      }    ]);  })();

.email {    background-image: linear-gradient(#fff, #ccc);    border: solid 1px #000;    padding: 10px;  }  .emailinfo {    background-image: linear-gradient(#fff, #fbee95);    border: solid 1px #000;    padding: 10px;  }  .option-clicked {    font-weight: bold;  }
