Getting the value of a the currently selected radio button may be done in a couple of ways. This is one approach using YUI 3.

Here is the HTML:

<input type="radio" name="myoptions" value="one"> First
<input type="radio" name="myoptions" value="two"> Second
<input type="radio" name="myoptions" value="three"> Third

Get the currently selected value using only one line of code:

var value = Y.one('[name=myoptions]:checked').get('value');

Unfortunately, this does not work in Internet Explorer, so another (not as tight) approach is:

function getRadioSelectedValue(selector) {
    var tmpValue= false;
    Y.all(selector).each(function(node) {
        if (node.get('checked') tmpValue = node.get('value');
    });
    return tmpValue;
}
var value = getRadioSelectedValue('.myRadioGroupClass'); // this assumes you've set appropriate class to radio elements
