frame detection script

**lordphlegthon** · Jul 23, 2002 08:32

Hello,

I need a script that detects if the browser is viewing a certain page within a frameset, and if it is not, to open the page through frameset instead.

For example if the site has a mainframe and a navframe, if someone goes to the mainframe from a search engine, the script will open up the frameset html so the navframe shows up too.

If someone can help me with this I would appreciate it muchly.

well say you have content.html but index.html is the framepage into which it would normally be loaded.
In content.html just say:

if (window.location == this.location) window.location='index.html';

.oO ( something like that - i think )

Are you wanting to load the requested page into the frameset? Or just pull up the default frameset?

Here's some cut and paste code I did about a year ago that handles what I think you are after. First, the frameset source code:

Code:

<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<script language="javascript">
   var content = "body.htm";
   var theRefer = document.referrer;
   var okLink = false;
   if (theRefer.indexOf(parent.location.host) != -1)
   	theRefer = "";
   if (theRefer == "")
	okLink = true;
   if (document.cookie != "" && okLink == true && parent.location.href.indexOf('.htm') != -1)
	content = document.cookie;
</script>

</head>


<script>

document.write('<frameset rows="105,*,60" frameborder="NO" border="0" framespacing="0" cols="*">');
document.write('<frame name="topFrame" scrolling="NO" noresize src="top.htm" frameborder="NO" >');
document.write('<frameset cols="212,*" frameborder="NO" border="0" framespacing="0" rows="*"> ');
document.write('<frame name="leftFrame" scrolling="NO" noresize src="side.htm" frameborder="NO">');

// This is the line that does the work
document.write('<frame name="mainFrame" src=' + content + ' frameborder="NO">');
// This is the line that does the work

document.write('</frameset>');
document.write('<frame name="bottomFrame" src="bottom.htm" scrolling="NO" noresize frameborder="NO">');
document.write('</frameset>');

</script>

<noframes>
<body bgcolor="#FFFFFF" text="#000000">
</body>
</noframes>
</html>

Next, is the sourcecode for 'noframes.js'

Code:

var framesetName = "index2.htm" // Enter the name of your framset page here

if (parent.frames[0] == null){

	var foundPointer = false;
	var fullUrl = parent.location.href;
	
	if (fullUrl.indexOf(framesetName) == -1) 
		{
		var lengthOfUrl = fullUrl.lastIndexOf('/');
		var topicUrl = fullUrl.substring(lengthOfUrl+1);
		window.document.cookie = topicUrl;
		foundPointer = true
		}
	
	if (foundPointer == true)
	window.location.href = framesetName;	
}

On every page that you want to 'jump into' the frameset, simplay include the 'noframes.js' file

Code:

<script language="javascript" src="js/noframes.js"></script>

You can see this code working at www.medivisuals.com. Visit this page http://www.medivisuals.com/prof.htm to see what happens (no longer at prof.htm, but at frameindex.htm with prof.htm in the contentFrame)

This code is old, so I'm not sure of it's compatiblity from a browser standpoint...

Hey there again. I was rummaging around in my dusty computer files and found this .js file for handling frames.
This is more recent (slightly) than the code I put in my above post, and has built-in documentation.

Enjoy.
