This is where we will create a simple interface for our application. This code will only display the html content 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 Display Random Player Name</h3>
  15. <hr style="border-top:1px dotted #ccc;"/>
  16. <div class="col-md-8">
  17. <div id="result"></div>
  18. </div>
  19. <div class="col-md-4">
  20. <center><button class="btn btn-success" onclick="displayRandom()">Display Name</button> <a href="index.html" class="btn btn-danger">Reset</a></center>
  21. </div>
  22. </div>
  23. <script src="script.js"></script>
  24. </body>
  25. </html>

This is where the main function of the application is. This code will display a random player name 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. let count=1;
  3. function displayRandom(){
  4. let html;
  5. var firstname = ["Kiryu", "John", "Peter", "Wendell", "Claire", "Jake"];
  6. var lastname= ["Choco", "Smith", "Pan", "Twenties", "Temple", "Pavel"];
  7. let rand_first = Math.floor(Math.random()*firstname.length);
  8. let rand_last = Math.floor(Math.random()*lastname.length);
  9. html="<h5>Player "+count+"</h5>"
  10. +"<h3>"+firstname[rand_first]+" "+lastname[rand_last]+"</h3>"
  11. +"<hr style='border-top:0.5px dashed #000;'/>";
  12. document.getElementById('result').innerHTML+=html;
  14. count++;
  17. }
