This is the link for the template that i used for the layout design

Creating The Interface

This is where we will create a simple interface for our application. This code will only display the string and the buttons. To create this simply copy and write it into your text editor, then save it 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="">Sourcecodester</a>
  10. </div>
  11. </nav>
  12. <div class="col-md-3"></div>
  13. <div class="col-md-6 well">
  14. <h3 class="text-primary">How to Remove All Vowels From a String</h3>
  15. <hr style="border-top:1px dotted #ccc;"/>
  17. <a class="btn btn-default" href="index.html">Reset</a>
  18. <button class="btn btn-default" onclick="displayStr();">Remove All Vowels</button>
  19. <br /><br />
  20. <div id="result" align="justify" style="padding:10px; border:5px dashed #000; font-size:20px;">A snake charmer is a person who moves the streets with different types of the banks of the river Yamuna. It is snakes in his basket. He goes from one place to another to show various types of snakes and their tricks. He carries a pipe with which he plays music and snakes dance to his tune. He usually wears a colourful dress. The job of a snake charmer is quite dangerous. Some snakes are quite poisonous and can even bite him. It is not an easy task to catch and train them for the shows.</div>
  21. </div>
  22. <script src="script.js"></script>
  23. </body>
  24. </html>

Creating JavaScript Function

This is where the main function of the application is. This code will dynamically remove all the vowels when the button is clicked. To do this just copy and write these block of codes inside the text editor and save it as script.js.
  1. function displayStr(){
  2. let data = document.getElementById('result');
  3. data.innerHTML = removeVowels(data.innerHTML);
  4. }
  6. function removeVowels(str){
  7. return str.replace(/[aeiou]/gi, '');
  8. }

The code above is the code that we use to remove the vowels from a string. In order to remove the vowels first we must create a method called removeVowels(). In this code it will only return the string value you have set, and it will replace all the vowels in the string using replace() function with a set regex. Lastly we will only create a method that will display the replaced vowel into the html content.
