    write to a different frame


    Hi,

    I've written a very simple test HTML/JS program where
    the JS code in one frame writes to a different frame with
    "parent.frame1. document.write( ...".
    This seems to work ok with IE-6, but with NS-7, after the
    first write, the "loading" seems to loop forever and if you
    click on "stop", the write will not work anymore. Also in
    NS, if you push reload, the write will not work anymore.
    Both NS and IE seem to perform the write slowly, and in
    multiple writes in rapid succession, some will be dropped.

    Can someone help ?

    Thanks
    Ray

      The "loading" state stays until you close the document again
      (i.e., "parent.fra mes['frame1'].document.close ()").

      How "not work". What does the javascript console say?

      Weird, but that's all I can say without seeing the code.

          If you close, to stop the loading, it appears that you cannot
          write to it again.

          a. "not work" = nothing written
          b. I have gotten the JS console to give errors, but not can not make
          it repeatable. The error is somthing like: "...undocumente d error..."

                  You can, but when you do, you open the document again, which
                  clears it. So the old line is erased, and a new, identical, line
                  is written.

                  Document.write is only meant for using while a document is being
                  loaded. That is why an opend document triggers the "loading" icon
                  stat in Mozilla/Netscape. There is no way to avoid this if you use
                  document.write to write the data to the new page.

                  Alternatives are using .innerHTML or DOM (where I prefer DOM):

                  var otherDoc = parent.frames['frame1'].document;
                  otherDoc.body.a ppendChild(othe rDoc.createText Node("Hello"));
                  [color=blue]
                  > a. "not work" = nothing written[/color]

                  I can see the problem in Mozilla.

                  I can't reproduce that, though. I am using Mozilla 1.5a (or usually
                  Mozilla Firebird 0.6). I don't get lost lines, slow writing or funny
                  error messages, so I can't help you with that.
