Creating The Interface

This is where we will create a simple interface for our application. This code will display an interface that will a short phrase. 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"/>
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
  6. blockquote {
  7. background: #f9f9f9;
  8. border-left: 10px solid #ccc;
  9. margin: 1.5em 10px;
  10. padding: 0.5em 10px;
  11. quotes: "\201C""\201D""\2018""\2019";
  12. }
  13. blockquote:before {
  14. color: #ccc;
  15. content: open-quote;
  16. font-size: 4em;
  17. line-height: 0.1em;
  18. margin-right: 0.25em;
  19. vertical-align: -0.4em;
  20. }
  21. blockquote p {
  22. display: inline;
  23. }
  24. </style>
  25. </head>
  26. <nav class="navbar navbar-default">
  27. <div class="container-fluid">
  28. <a class="navbar-brand" href="">Sourcecodester</a>
  29. </div>
  30. </nav>
  31. <div class="container-fluid">
  32. <div class="row">
  33. <div class="col-md-3"></div>
  34. <div class="col-md-6 well">
  35. <h3 class="text-primary">How to Remove Punctuation in a Phrase</h3>
  36. <hr style="border-top: 1px SOLID #8c8b8b;"/>
  38. <blockquote id="text">One happy customer wrote: "This is the best program-- that I have ever seen!"</blockquote>
  39. <button onclick="rem();">Remove Punctuation</button> <button onclick="reset();">Reset</button>
  40. </div>
  41. </div>
  42. </div>
  43. </body>
  44. <script src="script.js"></script>
  45. </html>

Creating JavaScript Function

This is where the main function of the application is. This code will dynamically remove the punctuation within a phrase To do this just copy and write these block of codes inside the text editor and save it as script.js.
  1. function rem(){
  2. const text=document.getElementById("text").innerHTML;
  5. const remPunc = text.replace(/[.,\/#!$%"\^&\*;:{}=\-_`~()]/g, "").replace(/\s{2,}/g, " ");
  7. document.getElementById("text").innerHTML=remPunc;
  9. }
  11. function reset(){
  12. window.location="index.html";
  13. }

In this code we display a simple phrase using the html tag blockqoute and bind it an id called text. We create a method to enclose multiple functions, we then get the value text id. We use the replace function to remove any characters base on the given argument, in my case we only targeted special characters with the use of the regex.
