To change the icon upon click with angularJs

Question

Here is the Html displaying only one icon now, but what I want is that whenever that edit icon is being clicked it changes to save icon immediately.

Below is the html:

<td style="padding:5px!important;">
                            <i class="fa fa-edit" ng-click="updateEmp()">
                      </td>

And down below is the JS file, is there any way to add the html bind to the JS File? JS Code:

$scope.updateEmp =  function (){
            $scope.isReadonly = false;
            console.log("update Employee");
        }

Answer 1

You can use ng-class and toggle the class on click as follows.

ng-class="{'fa fa-save' : toggle, 'fa fa-edit' : !toggle}"

DEMO

 var myApp = angular.module('myApp',[]); myApp.controller('MyCtrl',function($scope){ $scope.updateEmp = function (){ $scope.toggle = !$scope.toggle; } });
