Open in mainframe.

Halling · Jul 2, 2003

I have a script that prevents individual pages of my webpage to be opened outside my frames. It looks like this:

if (top.frames.length == 0) {top.location.href="/?" + self.location};

One problem with this is that it first loads the frameset with my welcome-page. First when the welcome-page has loaded completely it is replaced with the requested page.

How can I change the script so it doesn’t open the welcome-page first, but go directly to the requested page?

How do I complement the script to prevent my pages to be opened in frames of another website (deep-linking).

this thread: thread216-577858

shows how to make both a framebuster and prevent deep-linking. note it uses an iframe, so you may have to modify. you'll also need to modify the specific frame and document names ("sara", "index_main.html&quot

Thanks for the reply, but unfortunately I don’t use iframe, just “ordinary” frames. As I understand it Iframe is less supported by old browsers, so for the compability I will continue with the old frames.

Is there I way to adapt the script to ordinary frames? You write “put it in index”, but how can that work? You need to put some code on every page, right? Maybe I misunderstand everything because I have never used Iframe.

Conclusion; Still needs help!

what i mean by "put it in index" is to put the script in your index file or frameset file.

what you'll have to do depends on how your frameset is set up, but here's an example with two frames.

Code:

<script type=&quot;text/javascript&quot;>
//  the name of your frameset page
var sFrameset = &quot;index.html&quot;;

//  the name of your main content frame
var sMainframe = &quot;mainFrame&quot;;

//  the name of your main content frame default page
var sDefault = &quot;myDefaultPage.html&quot;;

window.onload = function(){ 
    if (parent.frames.length > 0) {
        if (parent != self) {
            var sPage = self.frames[sMainframe].location.href;
            parent.location.href = sFrameset + &quot;?&quot; + sPage;
        }
    }
}

var s = location.search.substring(1);
var src = s.length ? s : sDefault;

document.write('<frameset rows=&quot;75,*&quot;>');
document.write('<frame name=&quot;topFrame&quot; src=&quot;top.html&quot;/>');
document.write('<frame name=&quot;' + sMainframe + '&quot; src=&quot;' + src + '&quot;/>');
document.write('<\/frameset>');
</script>

you'd need to change the vars sFrameset, sMainframe and sDefault accordingly, as well as the other frame names/dimensions etc inside the write() statements

Sorry, but I still don’t understand… :-/
My file index.html looks like this:

---File index.html start---
<HTML>
<HEAD>
Some tags here...
</HEAD>

<FRAMESET cols="180,*" FRAMEBORDER=0 BORDER=0 FRAMESPACING=0>
<FRAMESET rows="60,*" FRAMEBORDER=0 BORDER=0 FRAMESPACING=0>
<FRAME SRC="tom.html" SCROLLING="NO" NORESIZE>
<FRAME SRC="meny.html" NORESIZE>
</FRAMESET>
<FRAMESET rows="155,*" FRAMEBORDER=0 BORDER=0 FRAMESPACING=0>
<FRAME SRC="logo.html" SCROLLING="NO" NORESIZE>
<FRAME SRC="vaelkommen.html" NAME="main" NORESIZE>
</FRAMESET>

<noframes>
<p>Sorry, frames needed</p>
</noframes>

</FRAMESET>
</HTML>
---File index.html end---

I guess I should put the code here? But if I type

http://www.mydomain.com/page2.html,

how can that page break out of alien frames and load into my frameset in the “main”-frame (i.e replace vaelkommen.html), only based on code in index.html?? I still think that I do need to put some code in page2.html!

I’m a bit confused…

jemminger · Jul 2, 2003

this should do it:

<html>
<head>
<title></title>

<script type="text/javascript">
// the name of your frameset page
var sFrameset = "index.html";

// the name of your main content frame
var sMainFrame = "main";

// the name of your main content frame default page
var sDefault = "vaelkommen.html";

window.onload = function(){
// if parent has frames...
if (parent.frames.length > 0) {
// ...but the parent is not this page...
if (parent != self) {
// ...get the currently displayed main frame page...
var sPage = self.frames[sMainFrame].location.href;
// ...and break out of the evil parent frame into our own
parent.location.href = sFrameset + "?" + sPage;
}
}
}

var s = location.search.substring(1);
var src = s.length ? s : sDefault;

document.write('<frameset cols="180,*" frameborder=1 border=1 framespacing=0>');
document.write('<frameset rows="60,*" frameborder=1 border=1 framespacing=0>');
document.write('<frame src="tom.html" scrolling="no" noresize>');
document.write('<frame src="meny.html" noresize>');
document.write('</frameset>');
document.write('<frameset rows="155,*" frameborder=1 border=1 framespacing=0>');
document.write('<frame src="logo.html" scrolling="no" noresize>');
document.write('<frame src="' + src + '" name="main" noresize>');
document.write('</frameset>');
document.write('<noframes>');
document.write('<p>Sorry, frames needed</p>');
document.write('</noframes>');
document.write('</frameset>');
</script>

</head>

</html>

and then put this in each of your content pages, to make sure they're always displayed in the frameset:

<script type="text/javascript">
if (parent == self) location.replace("index.html?"+location.href);
</script>

=========================================================
try { succeed(); } catch(E) { tryAgain(); }

Thanks, it works almost perfect.

* Prevents

http://www.mydomain.com/page2.html

form open outside the frameset. GOOD!
* Prevents deep linking to

http://www.mydomain.com.

GOOD!

But it doesn’t prevent deep linking to

http://www.mydomain.com/page2.html.

Maybe that is hard to do? Or can the script easily by complemented with that function?

jemminger · Jul 4, 2003

this should do it - replace in each content page this:

<script type="text/javascript">
if (parent == self) location.replace("index.html?"+location.href);
</script>

with this:

<script type="text/javascript">
// if page not opened in our frameset, do so
if (parent == self) location.replace("index.html?"+location.href);

// if page is deep linked, open in our frameset
try {
// if parent is a different domain, this should fail...
if (parent.frames[0].src != "tom.html&quot

{
location.replace("index.html?"+location.href);
}
} catch(E) {
// ...so this should execute
location.replace("index.html?"+location.href);
}
</script>

Well, well. That didn’t work…

When typing

http://www.mydomain.com/page2.html

the script goes into an eternal loop. The reason is that the expression “if(parent.frames[0].src != "tom.html&quot

” evaluates true.

I made an experiment by putting this code into page2.html:

-----------------------------------
<script type="text/javascript">
document.write("Script is alive&quot

;

if (parent == self) location.replace("index.html?"+location.href);

if (parent.frames[0].src == "tom.html&quot

document.write("tom&quot

;
if (parent.frames[0].src == "meny.html&quot

document.write("meny&quot

;
if (parent.frames[0].src == "index.html&quot

document.write("index&quot

;
if (parent.frames[0].src == "logo.html&quot

document.write("logo&quot

;
if (parent.frames[0].src == "vaelkommen.html&quot

document.write("vaelkommen&quot

;

if (parent.frames[1].src == "tom.html&quot

document.write("tom&quot

;
if (parent.frames[1].src == "meny.html&quot

document.write("meny&quot

;
if (parent.frames[1].src == "index.html&quot

document.write("index&quot

;
if (parent.frames[1].src == "logo.html&quot

document.write("logo&quot

;
if (parent.frames[1].src == "vaelkommen.html&quot

document.write("vaelkommen&quot

;

if (parent.frames[2].src == "tom.html&quot

document.write("tom&quot

;
if (parent.frames[2].src == "meny.html&quot

document.write("meny&quot

;
if (parent.frames[2].src == "index.html&quot

document.write("index&quot

;
if (parent.frames[2].src == "logo.html&quot

document.write("logo&quot

;
if (parent.frames[2].src == "vaelkommen.html&quot

document.write("vaelkommen&quot

;
</script>
-----------------------------------

And then typed

http://www.mydomain.com/page2.html.

The page opened in my frameset like it should, but only the first text “script is alive” vas printed.

I have been searching the Internet trying to find a solution to prevent the deep-linking I mentioned above. I found this script:

http://www.javascriptkit.com/script/cut170.shtml

It works in IE, but not in Netscape or Opera.

How can such a basic problem be so hard to solve…? :-/

Halling · Jul 6, 2003

Got it working in Netscape now. Were some problems with old files in the cashe I think. Still don’t work in Opera, but I can live with that!

So I’m closing the lid on this problem now. Thanks A LOT for all help!!
