"Must visit from" javascript wont work in IE…

Copy linkTweet thisAlerts:
Nov 25.2005

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?

[CODE]
<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>
[/CODE]

Cheers,
NuGG

var refarray = new Array();
refarray[0] = new Array();
refarray[0] = ['mysite.com']['redirectsinceitisfromyoursite]
var i;

for (i=0;i&lt;refarray.length;i++)
{
if (document.referrer!=refarray[i])
{
window.location.replace('pagetoredirecto.html');
}
else
{
window.location.replace(refarray[i][1]);
}
}
&lt;/script&gt;

@NuGGauthorNov 25.2005 — That doesnt script appear to work either as you can access the page without visiting the required previous page. Or it could be that ive edited it wrong or something. Take a look:

[CODE]<SCRIPT LANGUAGE="JavaScript">
var refarray = new Array();
refarray[0] = new Array();
refarray[0] = ['www.kings-head-inn.com']['redirectsinceitisfromyoursite] [B]\What goes here? I dont really understand...[/B]
var i;

for (i=0;i<refarray.length;i++)
{
if (document.referrer!=refarray[i])
{
window.location.replace('http://www.kings-head-inn.com/fudge/index.htm');
}
else
{
window.location.replace(refarray[i][1]);
}
}
</script>
[/CODE]

I want it to only allow people to access the http://www.kings-head-inn.com/fudge/[B]Success.htm[/B] page if they have just been on the http://www.kings-head-inn.com/fudge/[B]index.htm[/B] page.

@felgallNov 25.2005 — document.referrer is one of those fields that might contain the last page visited or might contain blank.

It contains blank if the field is turned off by your visitor in their web browser or firewall. It is also blank when coming from a secure page in IE.

Success!
