Maybe not the best way, but this works for me:
<html>
<head>
<script type="text/javascript"
src="mochikit-svn/MochiKit/MochiKit.js"></script>
</head>
<body>
<div id="radios">
<input type="radio" name="test" value="1" />1<br />
<input type="radio" name="test" value="2" />2<br />
<input type="radio" name="test" value="3" />3<br />
</div>
<input type="button" value="check"
onclick="alert(filter(itemgetter('checked'), $$('#radios
input[name=test]'))[0].value);" />
</body>
</html>
The code part with nicer formatting is:
var selectedvalue = filter(
itemgetter('checked'),
$$('#radios input[name=test])
)[0].value;
the "#radios" part is not strictly necessary, but it spares the
Selector module from traversing the whole document in searching for
the radiobuttons.
You end up with "undefined" if no radio is checked.
