"Must visit from" javascript wont work in IE...

Nov 24th, 2005

I have obtained the following script which only lets a page load if the visitor has been to the previous page, if they haven’t it sends the visitor to the appropriate page. However, it only works in Mozilla. Can anyone help me adapt this script to work in Internet Explorer?

 Help with Code Tags 
 JavaScript / DHTML / AJAX Syntax (Toggle Plain Text) 
<SCRIPT LANGUAGE="JavaScript" > 
<!-- Begin
var requiredfrom = "http://domain.com/somepage.htm"; //  required prev. page
if (document.referrer.indexOf(requiredfrom) == -1) {
alert("You must logon first...");
window.location=requiredfrom;
}
//  End --> 
</script>
<SCRIPT LANGUAGE="JavaScript" > 
<!-- Begin
var requiredfrom = "http://domain.com/somepage.htm"; //  required prev. page
if (document.referrer.indexOf(requiredfrom) == -1) {
alert("You must logon first...");
window.location=requiredfrom;
}
//  End --> 
</script>

Cheers,
NuGG

If you need an example of this script in action click here.

P.S. When I try this script in IE I receve the "must logon first" error regardless of visiting the previous page or not.

How odd. What version of IE are you using? I've tried it on multiple computers with IE 6.0 and it didnt work on any of them...

Its quite odd that it didnt work for me in IE but it works for you. Could it be something to do with the history settings in IE, or would that not make any difference?

The script works perfectly every time in firefox so i dont understand why it shouldnt work in IE.

document.referrer may contain the address of the previous page or it may not. There are a number of factors that can affect this such as browser settings, firewall settings, IE also suppresses the value if the prior page was on a secure server, etc. If this happens then you have no way to tell what page your visotir was on previous to coming to your page.

Then when I clicked the word "here" I got the you must log on message in a popup.

Whether the script works or not can depend on the browser and firewall settings on individual computers. That would be the reason some people say it works and others say it doesn't. You can't rely on document.referrer containing anything as there are too many different ways it can be turned off.
