In this tutorial we will create a Simple Automatic Word Counter using JavaScript. This code can detect and count the words that have been type by the user automatically. The code use onkeyup() to trigger a method that count words simultaneously every time the words have been inputted. This is helpful for the student that needed to know the amount of words in their project.

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="width=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 - Simple Automatic Word Counter</h3>
  16. <hr style="border-top:1px dotted #ccc;"/>
  17. <div class="col-md-6">
  18. <div id="result"></div>
  19. </div>
  20. <div class="col-md-6">
  21. <div class="form-group">
  22. <textarea class="form-control" onkeyup="autoCount(this.value);" style="resize:none; height:150px;"></textarea>
  23. </div>
  24. <button class="btn btn-success" onclick="clearAll()">Clear All</button>
  25. </center>
  26. </div>
  27. </div>
  28. <script src="js/script.js"></script>
  29. </body>
  30. </html>

Creating the Script

This code contains the script of the application. This code will count the words when entered. 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. function clearAll(){
  2. document.getElementById("result").innerHTML = "";
  3. document.getElementById("words").value="";
  4. }
  5.  
  6. function autoCount(val) {
  7. var count = parseInt(val);
  8. var wordCount=val.split(" ");
  9. document.getElementById("result").innerHTML = "Total number of words:" + " <label class='text-primary' style='font-size:20px;'>"+wordCount.length+"</label>";
  10. }

There you have it we successfully created a Simple Automatic Word Counter 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!
