jQuery get the value from from checked radio input which wasn't checked before : I got follow HTML:

    <input type="radio" name="eingangstuer_pfostenbefestigung" value="Zum Einbetonieren" />
    <input type="radio" name="eingangstuer_pfostenbefestigung" value="Zum Einduebeln" />

Ater I check one of them and try to get the value with:

    $("input[name=eingangstuer_pfostenbefestigung]:checked").val();

I get NaN, it only works when one of the the values is checked BEFORE. Are there any solutions for the js bug nr. 666?
