<html lang="en">
<head>
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>Document</title>
</head>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<body>
   <form action="#">
      <label for="firstName">First Name:</label>
      <input type="text" id="fName" name="firstName" placeholder="Enter your First Name" />
      <button type="submit" onclick="submitForm(event)">Submit</button>
   </form>
<span id="result"></span>
</body>
<script>
   var firstName = null;
   function submitForm(evnt) {
      evnt.preventDefault();
      firstName = document.getElementById("fName").value;
      document.getElementById("result").innerHTML = "The First Name is=" + firstName;
