jQuery get which radio is selected

Use the :checked selector along with the radio selector.
With form id, can do this

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

//or

$("#myform input[type='radio']:checked").val();

Without form is, it will still work:

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