Radio button selected?

Question

I\'d like to know for a specific radio button group if a radio button is selected or not with jQuery.

Thanks

Answer 1

if( $('input[name=groupName]').is(':checked') ){
      //do something
}

or my original answer before Paulo woke me up

  if( $('input[name=groupName]:radio:checked').length ){
      //do something
  }
