javascript - ng-click function logs if and else statement -


in test.js controller if/else statement log out object ng-click

   angular.module('stationeryapp')   .factory('cards', function () {     var cards = [];     return cards   })   .controller('testctrl', function ($scope, $log, cards) {     $scope.cards = cards     $scope.cardclick = function () {       if ($scope.card['fname']!=="" && $scope.card['lname']!=="") {         $scope.cards.push($scope.card)         $scope.card={fname:'',lname:''}         console.log($scope.card);       } else {         console.log($scope.card);       }     }   });

this test.html:

<div>   <md-toolbar layout='column' layout-align='center'>         <md-button layout-margin layout-padding flex='100' class='md-raised md-primary'>           <h1>{{ card.fname }}</h1>           <h1>{{ card.lname }}</h1>         </md-button>         <div layout='column' layout-align='center center' >           <input type="text" style="color:black;" flex='' ng-model="card.fname">           <input type="text" style="color:black;" flex='' ng-model="card.lname">         </div>   </md-toolbar> </div>

without if statement cards array has 2 objects pushed every time cardclick() invoked. first object whatever ng-model inputs , second object always empty strings.

example:

fname input = "stack" lname input = "overflow" cardclick() result --> cards = [{fname:"stack", lname:"overflow"},{fname:"",lname:""}]  fname input = "java" lname input = "script" cardclick() result --> cards = [{fname:"stack", lname:"overflow"},{fname:"",lname:""},{fname:"java",lname:"script"},{fname:"",lname:""}]

including if statement yield desired result

example:

fname input = "stack" lname input = "overflow" cardclick() result --> cards = [{fname:"stack", lname:"overflow"}]  fname input = "java" lname input = "script" cardclick() result --> cards = [{fname:"stack", lname:"overflow"},{fname:"java",lname:"script"}]

my question why if statement bring result , why the if/else statement in test.js log out if , else result each time cardclick() invoked.

edit

here code without if/else. renders result in first example.

angular.module('stationeryapp')   .factory('cards', function () {     var cards = [];     return cards   })   .controller('testctrl', function ($scope, $log, cards) {     $scope.cards = cards     $scope.cardclick = function () {         $scope.cards.push($scope.card)         $scope.card={fname:'',lname:''}         console.log($scope.card);     }   });

this line:

console.log($scope.card);

appears in both if statement , else statement. see logged either way.

as if/else question, can provide code if/else removed can compare?
