It is a kind of template that extends HTML to a new level of coding techniques. It is mostly used by other well known site for creating a template.

This code contains the interface of the application. This code will render application and display the form. To do that just kindly write these block of code inside the text editor and save this as index.html.

  1. <!DOCTYPE html>
  2. <head>
  3. <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scal=1"/>
  4. <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
  5. </head>
  6. <nav class="navbar navbar-default">
  7. <div class="container-fluid">
  8. <a class="navbar-brand">Sourcecodester</a>
  9. </div>
  10. </nav>
  11. <div class="col-md-3"></div>
  12. <div class="col-md-6 well">
  13. <h3 class="text-primary">JavaScript - Simple Countdown Timer Using AngularJS</h3>
  14. <hr style="border-top:1px dotted #ccc;"/>
  15. <div class='wrap' ng-app='app'>
  16. <div class='time-to'>
  17. <center style="font-size:50px;">Christmas Countdown</center>
  18. <br />
  19. <center><span style="font-size:40px; color:red;" countdown='' date='December 25, 2019 00:00:00'></span></center>
  20. <center style="font-size:25px; color:blue;">Before Christmas</center>
  21. </div>
  22. </div>
  23. </div>
  24. <script src="js/angular.js"></script>
  25. <script src="js/script.js"></script>
  26. </body>
  27. </html>

Creating the Script

This code contains the main function of the application. This code will start counting when the web page is start. To that just kindly copy and write these block of codes inside the text editor, then save it as script.js

  1. (function() {
  2. var app;
  3. app = angular.module('app', []);
  4. app.directive('countdown', [
  5. 'Util', '$interval', function(Util, $interval) {
  6. return {
  7. restrict: 'A',
  8. scope: {
  9. date: '@'
  10. },
  11. link: function(scope, element) {
  12. var future;
  13. future = new Date(scope.date);
  14. $interval(function() {
  15. var diff;
  16. diff = Math.floor((future.getTime() - new Date().getTime()) / 1000);
  17. return element.text(Util.dhms(diff));
  18. }, 1000);
  19. }
  20. };
  21. }
  22. ]);
  23. app.factory('Util', [
  24. function() {
  25. return {
  26. dhms: function(t) {
  27. var days, hours, minutes, seconds;
  28. days = Math.floor(t / 86400);
  29. t -= days * 86400;
  30. hours = Math.floor(t / 3600) % 24;
  31. t -= hours * 3600;
  32. minutes = Math.floor(t / 60) % 60;
  33. t -= minutes * 60;
  34. seconds = t % 60;
  35. return [days + 'd', hours + 'h', minutes + 'm', seconds + 's'].join(' ');
  36. }
  37. };
  38. }
  39. ]);
