In this tutorial we will create a Redirect After 5 Seconds using JavaScript. This code will generate a timer that will start running until it reaches the peak then redirect the user. The code use a setTimeout function to initiate a countDown() that decrement a value continuously when the start button is clicked. This is a free user-friendly kind of program, you can modify it and apply to your working application.

We will be using JavaScript as a server-side scripting language because It allows greater control of your web page behavior than HTML alone. It is embedded in HTML that responsible to allow user to interact with the computer .

Getting started:

First you have to download bootstrap framework, this is the link for the bootstrap that I used for the layout design https://getbootstrap.com/.

The Main Interface

This code contains the interface of the application. To create this just write these block of code inside the text editor and save this as index.html.

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="widht=device-width, initial-scale=1"/>
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
  6. </head>
  7. <nav class="navbar navbar-default">
  8. <div class="container-fluid">
  9. <a class="navbar-brand" href="<a href="https://sourcecodester.com">Sourcecodester</a>
  10. " rel="nofollow">https://sourcecodester.com">Sourcecodester</a>
  11. </a> </div>
  12. </nav>
  13. <div class="col-md-3"></div>
  14. <div class="col-md-6 well">
  15. <h3 class="text-primary">JavaScript - Redirect After 5 Seconds</h3>
  16. <hr style="border-top:1px dotted #ccc;">
  17. <br />
  18. <center><button class="btn btn-primary" onclick="tickTime(this);">Start Timer</button></center>
  19. <div id="display" style="display:none;"><center><h4>Please wait <span id="timer" class="text-primary">5</span> seconds to redirect you to main page</h4></center></div>
  20. </div>
  21. </body>
  22. <script src="js/script.js"></script>
  23. </html>

Creating the Script

This code contains the script of the application. This code will start a counting when the button is clicked. To do this just copy and write these block of codes inside the text editor, then save it as script.js inside the js folder.

  1. var timer = 5;
  2. var counter;
  3.  
  4. function startTimer() {
  5. counter = setInterval(countDown, 1000);
  6. }
  7.  
  8. function countDown() {
  9. var display = document.getElementById("timer");
  10. display.innerHTML = timer;
  11.  
  12.  
  13. timer--;
  14.  
  15. if (timer < 0) {
  16. clearInterval(counter);
  17.  
  18. window.location.href = "<a href="https://sourcecodester.com";
  19. " rel="nofollow">https://sourcecodester.com";
  20. </a> }
  21. }
  22.  
  23. function tickTime(btn){
  24. btn.style.display='none';
  25. document.getElementById('display').style.display="inline";
  26. startTimer();
  27. }

There you have it we successfully created a Redirect After 5 Seconds using JavaScript. I hope that this simple tutorial help you to what you are looking for. For more updates and tutorials just kindly visit this site. Enjoy Coding!
