I have a series of radio buttons with class="weight"
I thought I could get the current selected value with this:

$('.weight radio:checked').val()

...but does not seem to work. I also have them with a name="weight" so if its easier to do this by name, that would be an OK solution as well.

Thank you!

it should be

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

or just

$('.weight:checked').val()

just add << : >> and no space before radio : $(".weight:radio:checked").val()
test page : http://jsfiddle.net/dahVc/

$(".weight:radio").change(function() {
    //alert( $(this).val() );
    alert( $(".weight:radio:checked").val() );
})
