jQuery | :checked Selector

The :checked selector is used to select the all checked checkboxes, radio buttons and options of select elements.

Note: To retrieve only the selected options of select elements, use :selected selector.

Syntax:

$(":checked")

Below examples illustrate the :checked selector in jQuery:

Example 1: This example applies CSS to all checked elements(in this example, checkboxes).

<!DOCTYPE html>   
<html>   
  
<head>  
    <title>  
        jQuery | :checked Selector 
    </title> 
      
    <script src= 
"https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"> 
    </script> 
      
    <!-- Script to set style in checked selector -->
    <script> 
        $(document).ready(function() { 
            $(":checked").wrap("<span style='background-color:blue'>"); 
        }); 
    </script> 
      
    <style> 
        form { 
            font-weight: bold; 
            font-size: 25px; 
            color: green; 
        } 
    </style> 
</head>  
         
<body style="text-align:center;">   
     
    <h1>   
        jQuery | :checked Selector 
    </h1>   
             
    <form action=""> 
        GeeksForGeeks_1 <input type="checkbox" name="GFG_1"
                value="GFG_1" checked="checked" ><br> 
                  
        GeeksForGeeks_2 <input type="checkbox" name="GFG_2"
                value="GFG_2"  ><br> 
        GeeksForGeeks_3 <input type="checkbox" name="GFG_3"
                value="GFG_3" checked="checked" ><br> 
    </form>  
</body>   
  
</html>

    </script> 
      
    <!-- Script to set style in checked selector -->
    <script> 
        $(document).ready(function() { 
            $(":checked").wrap("<span style='background-color:red'>"); 
        }); 
    </script> 
      
    <style> 
        form { 
            font-weight: bold; 
            font-size: 25px; 
            color: green; 
        } 
    </style> 
      
</head>  
         
<body style="text-align:center;">   
  
    <h1>   
        jQuery | :checked Selector 
    </h1>   
             
    <form action=""> 
        GeeksForGeeks_1 <input type="radio" name="GFG_1"
