Diaplaying с фиксированным временем, используя Angular Js

0

Я пытаюсь показать время начала и окончания на странице онлайн-экзамена. Я показал начальное время моей экзаменационной страницы, и теперь я пытаюсь отобразить время окончания , увеличивая время в 1 минуту каждый раз, когда я открываю страницу с помощью AngularJs только так, как показано ниже:

Вопрос 1 из 5
Время начала 6:39:23
Время окончания 18:40:22

Здесь Код:

Ты пробовал

var endTime= new Date();
endTime.setMinutes(endTime.getMinutes() + 1);

Он также позаботится о часах, в случае 59 минут

Кредиты на: Как добавить 20 минут к текущей дате?

Объем кода для меня слишком сложный, но я написал вам быстрый пример того, как я буду представлять время начала с подсчетом таймера. Я включил кнопку остановки, чтобы сказать, когда остановиться, но вы можете остановить ее, как вам нравится:

https://plnkr.co/edit/ZBZDwC1qkh8S13vH0gSe?p=preview

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope, $timeout) {

  $scope.currentTime = new Date();
  $scope.startTime = angular.copy($scope.currentTime);

  var timer;

  $scope.stopCounter = function() {
      $timeout.cancel(timer);
  };

  var updateCounter = function() {
      $scope.currentTime.setSeconds($scope.currentTime.getSeconds() + 1)

      // Set the value to 60000 because you requested a minute apart

      timer = $timeout(updateCounter, 60000);
  };

  updateCounter();

});
