jQuery Web Development Front End Technology

To toggle content, use slideToggle() in JavaScript.

Following is the code: −

<!DOCTYPE html>
<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>
<style>
   .firstDiv {
      display: none;
   }
   .txtBox {
      display: block;
   }
</style>
<body>
   <button onclick="toogleTheTextBox()">Press Me to toggle the text box</button>
   <div id='firstDiv'>
      <br>
         <label>
         Enter your name:<input type='text' id='txtBox' />
         </label>
      <br>
   </div>
</body>
<script>
   function toogleTheTextBox() {
      $('#firstDiv').slideToggle(function () {
         $('#txtBox').focus();
      });
   }
</script>
</html>

To run the above program, save the file name anyName.html (index.html). Right click on the file and select the option “Open with Live Server” in VS Code editor.
