Answer 1

This would loop through all the radio elements in the document that have been checked:

$('input:radio:checked').each(function() {
    var value = $(this).val();
    // do something with radio or value
});

If you wanted to get the checked value of a particular radio group, you would do:

var value = $('input:radio[name=myradios]:checked').val();

So if your HTML was like this:

<input type='radio' name='myradios' value='1'>
<input type='radio' name='myradios' value='2' checked='checked'>
<input type='radio' name='myradios' value='3'>

value would be 2
