    Iframe Refresh

    I am using a shoutbox cgi and the messages are written to a file called
    tagbox.html using a form.

    After so many messages the file is blanked and new lines are written.

    I can cause a refesh say every 20 seconds by embedding a meta tag in the
    tagbox.html thus:

    <META HTTP-EQUIV="refresh" content="20">

    However this gets blanked out along with all the other message lines.

    tagbox.html is called into an iframe via a cgi script.

    I need a form of javascript to embed into the cgi script such that
    tagbox.html will be refreshed.

    Any ideas? Thanks.

      In your main page:

      <script type="text/javascript">

      var milliSecondsToW ait = 20000;

      function reloadIFrame(){
      document.frames['iFrameName'].location.href =
      "tagbox.htm l?" + (new Date().getTime( ));
      myVar = setTimeout("rel oadIFrame()",mi lliSecondsToWai t);
      }
      var myVar = setTimeout("rel oadIFrame()",mi lliSecondsToWai t);

      </script>

      <iframe id="iFrameName " src="tagbox.htm l"></iframe>

      The ?(new Date().getTime( )) is to make the URL unique and keep the file
      from being gotten from the cache.

      Enjoy

              Randy,

              I'm using your code to refresh a page in an iframe and jump to an anchor
              placed at the bottom of the iframe page.

              <html>

              <head>
              <script type="text/javascript">
              var milliSecondsToW ait = 5000;
              function reloadIFrame(){
              //document.frames['iFrame1'].location.href ="2.html?" + (new
              Date().getTime( ));
              window.frames['iframe1'].location = "2.html?" + (new Date().getTime( ));
              window.frames['iframe1'].location.hash= "#bottom"
              myVar = setTimeout("rel oadIFrame()",mi lliSecondsToWai t);
              }
              var myVar = setTimeout("rel oadIFrame()",mi lliSecondsToWai t);
              </script>
              </head>

              <body onload='reloadI Frame()'>
              test
              <p>&nbsp;
              <iframe height="450" width="600" src="2.html#bot tom" name="iframe1"
              scrolling="yes" >This browser does not support...</iframe>
              <p>&nbsp;
              test
              <form method="POST" action="--WEBBOT-SELF--">
              <p>
              <input type="text" name="T1" size="20">
              <input type="button" value="Button" name="B3">
              <input type="submit" value="Submit" name="B1">
              <input type="reset" value="Reset" name="B2"></p>
              </form>
              </body>
              </html>


              It works, but it also scrolls the page with the inserted iframe to the
              bottom! Any suggestions on how I can jump to the bottom of the iframe only?

              Nice code, thanks,
              Mike
