    Frame/form question

    Hi.

    I'm trying to build a page that has two frames, both of which are
    generated by a different cgi script.

    The lower frame is generated by a script called "control.py ".

    The upper frame is generated by a script called "getchat.py ".

    On the lower frame, there is a button called "REFRESH". When clicked, I
    want it to be able to read information in a hidden input on a form in the
    upper frame, that being .....

    <input type=hidden NAME="last_seen " value = "' + str(lastByteLoc ) + '">

    .... and submit that information to getchat.py.

    I have a javascript routine worked out which *usually* does that when I
    view the page with konqueror. Unfortunately it never seems to work with
    mozilla. Can anybody tell me why? And better still, how I can fix it?

    Here's the code generated by control.py ......

    In the <head> i have ....

    <script language = "javascript ">
    <!-- hide from older browsers

    function refreshPosts()
    {
    plast = parent.chatfram e.form1.last_se en.value;
    parent.chatfram e.location = 'getchat.py?las t_seen=' + plast
    }

    //-->
    </script>

    And on the form in the lower frame, I have this input ......

    <input type = "button" value = "REFRESH" onClick = "refreshPosts() ">

    Thanx in advance.

      parent.chatfram e is a window object. Form belongs to document.

      plast = parent.chatfram e.document.form 1.last_seen.val ue;

          or better yet (since I prefer to use the appropriate collections :)

          plast = parent.frames['chatframe'].document.forms['form1'].
          elements['last_seen'].value;

          There is no official standard for Javascript access to frames,
          so I can't say that using the frames collection is more official than
          just assuming the frames are direct properties of their parent.

          However, the W3C DOM specification requires the forms collection, and
          there is no requirement that forms are available as properties of the
          document element. That means that a (hypothetical) strictly standards
          adhering browser (implementing nothing unofficial) will only work
          using the forms collection.

          Ditto for the elements collection.

              Thanx. That does the job.

              Now it works perfectly with mozilla but sometimes breaks when using
              Konqueror. Specifically, when I press REFRESH, but there's nothing new to
              update the chatframe with. After that, REFRESH won't work again until I
              reload the whole page.

                  See Lasse's response - Konqueror may need the full reference instead of
                  the shortcut I'm used to (I do mostly intranet apps and only have to
                  deal with NN/IE).
