    How to find the value of a radio button

    Hi,

    Does anyone know how to use DOM to find the value of a selected radio
    both (or if none were selected)?

    My web page displays a set of radio buttons - the number is dynamic so
    could be one or 100; I do this within a loop.

    At the moment, I'm giving each one the same name and ID - not sure if
    giving the same ID is correct or not. By default, no radio buttons
    are selected when the page loads

    When the user clicks on a a specific button on the page, I need to
    check if a radio button was selected or not. I trap the 'click' event
    but my code to get the radio button value has failed.

    Thanks,
    Don

      A good place to start is the group FAQ

      http://jibbering.com/faq/#FAQ4_13


      The longer FAQ note linked in the answer to the above FAQ is valuable.

          Yes, see Peter's reply.

          My web page displays a set of radio buttons - the number is dynamic so
          could be one or 100; I do this within a loop.

          It is not correct, the value of each ID attribute must be unique in
          the page. Giving buttons the same name is OK, it forms them into
          groups. Onlly give them IDs if they really need them.
