Answer 1

Another Easy way to understand... It's Working:

HTML Code:

 <input type="radio" name="active_status" class="active_status" value="Hold">Hold 
 <input type="radio" name="active_status" class="active_status" value="Cancel">Cancel 
 <input type="radio" name="active_status" class="active_status" value="Suspend">Suspend

Jquery Code:

$(document).on("click", ".active_status", function () {
 var a = $('input[name=active_status]:checked').val();  
 (OR)   
 var a = $('.active_status:checked').val();
 alert(a);
});

Answer 2

You can get the value of selected radio button by Id using this in javascript/jQuery.

$("#InvCopyRadio:checked").val();

I hope this will help.

Answer 3

To get the value of the selected Radio Button, Use RadioButtonName and the Form Id containing the RadioButton.

$('input[name=radioName]:checked', '#myForm').val()

OR by only

$('form input[type=radio]:checked').val();

Answer 4

By Name only

$(function () {
    $('input[name="EventType"]:radio').change(function () {
        alert($("input[name='EventType']:checked").val());
    });
});

Answer 5

The best way to explain this simple topic is by giving simple example and reference link:-

In the following example we have two radio buttons. If the user selects any radio button, we will display the selected radio button value in a alert box.

Html:

<form id="Demo">
<input type="radio" name="Gender" value="Male" /> Male <br />
<input type="radio" name="Gender" value="Female" /> Female<br />
<input type="radio" name="Gender" value="others" /> others <br />
</form>

jquery:-

 $(document).ready(function(){
        $('#Demo input').on('change', function() {
            alert($('input[name="Gender"]:checked', '#Demo').val());
        });
    });

Answer 6

Just use.

$('input[name="name_of_your_radiobutton"]:checked').val();

So easy it is.
