How to Show and Hide div elements using radio buttons?

Last Updated : 03 Aug, 2021

In order to display data/content of a specific element by selecting the particular radio button in jQuery we can use the following two methods:

hide() methods: This method is used to hiding the syntax or the element of html that you want to hide.
Syntax:
```
$(selector).hide(speed, callback);
```
show() methods: This method is used to show the syntax or the element of html that you want the user to see.
Syntax:
```
$(selector).show(speed, callback);
```

Approach:

Selector name for radio button is same as the element which is used to display the
content.
CSS display property of each element is set to none using display: none;
Use show() method for displaying the element, otherwise use hide() method for hiding.

Example 1:

<!DOCTYPE html>
<html>
  
<head>
    <title>
      Show and Hide div elements using radio buttons
    </title>
    <script src=
"https://code.jquery.com/jquery-1.12.4.min.js">
    </script>
    <style type="text/css">
        .selectt {
            color: #fff;
            padding: 30px;
            display: none;
            margin-top: 30px;
            width: 60%;
            background: green
        }
          
        label {
            margin-right: 20px;
        }
    </style>
</head>
  
<body>
    <center>
        <h1 style="color:green;">

        <div class="Java selectt">

          many years.</div>
        <script type="text/javascript">
            $(document).ready(function() {
                $('input[type="radio"]').click(function() {
                    var inputValue = $(this).attr("value");
                    var targetBox = $("." + inputValue);
                    $(".selectt").not(targetBox).hide();
                    $(targetBox).show();
                });
            });
