How to Build a Simple Terminal like Website using jQuery?

We will start by creating a basic HTML structure for our website. Next, we will use jQuery to create a terminal-like interface by adding elements such as input fields and output displays. Finally, we will use jQuery functions to handle user input and display the appropriate response.

Let us first understand what jQuery is. jQuery is a JavaScript library that simplifies HTML document traversing, event handling, and animation. It allows for easy manipulation of the Document Object Model (DOM). It also provides several shorthand methods for common JavaScript tasks, such as making AJAX requests. It is widely used in web development to create interactive and dynamic user interfaces. It can be easily integrated with other libraries and frameworks.

Approach

Here is an approach of creating a simple terminal-like website using jQuery −

  • Create an HTML file with a '<div>' element to serve as the terminal window. Give it a unique ID, such as "terminal".

  • Include jQuery in your HTML file by linking to the jQuery library in the `<head>` section of your HTML file.

  • Create a JavaScript file and link to it in the `<head>` section of your HTML file.

  • In your JavaScript file, use jQuery to select the terminal `<div>` and add a class to it to style it as a terminal window.

  • Use jQuery to listen for the user's input in the terminal window. You can use the `.keyup()` event to detect when the user presses a key.

  • When the user presses enter, use jQuery to append their input as a new `<p>` element to the terminal '<div>'.

  • Use jQuery to append the response to the input as a new `<p>` element.

  • Repeat steps 5-7 for each command the user inputs.

Example

Here's an example of a simple terminal-like website built using jQuery −

<!DOCTYPE html>
<html>
<head>
   <title>Terminal like website</title>
   <style>
      #terminal {
         font-family: monospace;
         background-color: #000;
         color: #fff;
         padding: 20px;
      }
      #input {
         margin-top: 20px;
      }
      #prompt {
         font-weight: bold;
      }
      #cmd {
         background: transparent;
         border: none;
         color: white;
         outline: none;
      }
   </style>
</head>
   <body>
      <script src="https://code.jquery.com/jquery-3.1.0.js"></script>
         <div id="terminal">
            <div id="output"></div>
            <div id="input">
               <span id="prompt">$ </span>
               <input type="text" id="cmd">
            </div>
         </div>
      <script>
         $(document).ready(function() {
            $("#cmd").focus();
            $("#cmd").keypress(function(e) {
               if(e.which == 13) {
                  var cmd = $("#cmd").val();
                  $("#output").append("<div>$ " + cmd + "</div>");
                  $("#cmd").val("");
               }
            });
         });
      </script>
   </body>
</html>
