Question

I am trying like below to get the value of a checked radio button but it just keeps giving undefined. I am using Firefox on Ubuntu so I don’t know if its some weird quirk of the browser or what, I would appreciate any advice as this is driving me crazy:

            <input name="tagRow_ddd" type="radio" value="p">
                <input name="tagRow_ddd" type="radio" value="r">


alert($('input[name=tagRow_ddd]:checked').val())

Answer 1

that’s exactly the output it should give. the :checked selector only finds checked elements… you haven’t any.
