You can use the `:checked` selector if you to use jQuery to identify the selected Radio Button . This selector allows you to target the checked radio button in a group of radio buttons. Here’s a step-by-step guide on how to do it:
1. First, ensure that you have included the jQuery library in your HTML file. You can include it by adding the following line within the `<head>` section of your HTML:
“`html
<script src=”https://code.jquery.com/jquery-3.6.0.min.js”></script>
“`
Please note that you can use a different version of jQuery if needed.
2. Create your HTML form with radio buttons. Make sure to give each radio button a unique `name` attribute, and assign a common class to them (optional, but it can make your selector more specific):
“`html
<form>
<label><input type=”radio” name=”option” value=”option1″ class=”radio-option”> Option 1</label>
<label><input type=”radio” name=”option” value=”option2″ class=”radio-option”> Option 2</label>
<label><input type=”radio” name=”option” value=”option3″ class=”radio-option”> Option 3</label>
<!– Add more radio buttons as needed –>
</form>
“`
3. Use jQuery to identify the selected radio button. You can use the `:checked` selector along with the `:radio` selector to target the checked radio button, and then retrieve its value or any other attributes you need.
“`html
<script>
$(document).ready(function() {
// Use an event handler to detect changes in the radio button selection
$(‘.radio-option’).on(‘change’, function() {
// Use the :checked selector to get the selected radio button and retrieve its value
var selectedValue = $(‘input[name=option]:checked’).val();
// Display the selected value (for demonstration purposes)
console.log(‘Selected Value:’, selectedValue);
});
});
</script>
“`
In this example, whenever the user selects a different radio button, the code will output the selected value to the browser’s console.
Remember to adjust the selector according to your specific HTML structure and naming conventions. This code snippet should give you a good starting point to work with radio buttons and jQuery.
