[Javascript] Opening Intranet links with a set navigation frame

Tue Mar 20 11:17:29 CST 2001

    Come to think of it, if you want to make this even more foolproof, use Esther's suggestion for when somebody calls the page all by itself; check for the presence of a frameset, and if it's not there, redirect to the frameset but with the page name in the URL as in the code below.

  David,

      To do this properly, you'll probably want some type of server-side logic, but it can be done from the client (just a little bit messier and not as secure).

      First you'll send the URL with the page name attached in the querystring, e.g. 

  http://sitename/framepage.html?pagename=thispage.html

      Then in the page you can either retrieve the querystring by a nice clean server-side method, or you can parse the window.location.href and get the piece after "?pagename=" to find the page you want in the frame.

      From there it's just a matter of writing the necessary frameset code in the browser.  There's the server-side way, depending of course on what server you're using, and then there's the client-side JavaScript method (just use document.write).

      Here's a little demo I whipped up to get the page name out of the URL.  You have to click the link once to get the querystring value; let me know if you have any more questions.

  *******Sample code********

  <html>
  <head>
   <title>URL Variable Snatcher</title>
  </head>

  <body>
  <A HREF="testpage.html?pagename=booga.html">Click here</A><BR>
  <FORM>
  Top page: <INPUT NAME="field2" SIZE=80><BR>
  Frame page: <INPUT NAME="field1" SIZE=80>
  </FORM>
  <SCRIPT LANGUAGE="JavaScript">
  var pageName;
  var framePage;
  var startIndex;
  var endIndex;

  var pageName = window.location.href;
  var startIndex = window.location.href.indexOf("?pagename=") + "?pagename=".length;
  var endIndex = window.location.href.length;

  var framePage = pageName.substring(startIndex,endIndex);

  document.forms[0].field1.value = framePage;
  document.forms[0].field2.value = pageName;
  </SCRIPT>

  </body>
  </html>
  ******* End of Sample Code ********

    Let me know if this is possible...

    I'd like to be able to just pass in a URL and have that page open up in a frame with a set header.

    I do this now by setting up a separate file that sets the frames, but I like to have one script that I can pass the various URL's to. 

    Currently, most of the intranet site links we have open in separate browser windows, but I'd like to tighten-up our navigation with a navigation frame on top of all the links.

    Thanks
