using the messages-object on another page?

Posted on Sep 23, 2004 at 07:51 AM 14 Views

I used to show error messages on the top of my BSP-page by using the messages object. With <i>messages->add_message()</i>, I added the error messages and with <i>message->get_message()</i> I read and displayed them.

Now, I would like to show the messages on a popup-window that shows another BSP-page. Can I access the first page's messages object on the popup-page or is using a global messages object in the application class the only way?

    The right way is to use global messages object in the application class & statefull BSP.

    Other way is to transfer message table from page to page via navigation->set_parameter

      Keep in mind URL is limited to about 2Kb length. The navigation object does a browser redirect transfering the parameters via the URL (by default). Not recommended for tables.

    Daniel,

    I think it should be possible to use JavaScript to read the error message from another page.

    If, for example, the two pages are in the same frameset,

    and if the first frame contains the message element with

    id="MY_MESSAGE_ID", then something like the following could do the job:

    <script>

    <!--

    document.write(parent.frames[0].document.getElementById("MY_MESSAGE_ID-txt").firstChild.nodeValue;

    -->

    </script>

    In a popup window this will be more difficult. I know that there is something like self.creator.xxx.xxx etc., but I am not really sure if this works.

    But it's worth a try.

    Hope that helps.

    Best regards,

    Juergen

      No problem, I found the solution quickly to my issue:

      I use an empty bsp page called "PruebaPopUpamedida.htm"

      I use the following javascript code to calle this page and stablish its content and properties:

      And it seems it works, so thank you very much anyway, I hope I can manipulate the layout from the calling page in this script.

      Carlos.
