I have a web site where people are directed via links from 12 different web sites.
For example, if the user was on www.chevy.com, and they clicked on a link to win a trip to an awards show, they would then be sent to my web site to register. After they fill out their information, they press submit, and are taken to the thank-you web page. After 10 seconds they get redirected back to www.chevy.com.
Is there a way to use JavaScript to pass the original referral URL (www.chevy.com) to the thank-you page, where I can load it into a meta refresh tag?
Thanks - Tony

The code of Thank-You page will be something like this .... -
.
-
.
-
.
-
<head>
-
.
-
<META HTTP-EQUIV="Refresh" CONTENT="3;URL=http://www.some.org/some.html">
-
</head>
-
.
-

I know how to do the meta refresh tag, but I need to pass the variable of the referral URL to the second web page.
For example - they start at www.chevy.com. They click on a link that takes them to a registration page. They fill out the registration information, and click "submit". Then they are taken to a "thank-you" page, where I redirect them after 10 seconds to their original web page of www.chevy.com.
So, I need to know how to pass the referral URL between the registration and thank-you pages.

hi ...
you may pass it through a query-string that you append to the url: - whatever_url_you_have?referer=referal_url
in a webpage you retrieve the url with: - var url = window.location.href
and from that you may retrieve the query-string and the referal_url.
kind regards

Hi Tony. I would use the http referrer property and place it in a cookie.
On your registration page, create the cookie with this code in the <head>: -
<script type="text/javascript">
-
function setCookie(name,val,days) {
-
// DATE OBJECT
-
var date = new Date();
-
// NUMBER OF MILLISECONDS IN A DAY
-
var milliseconds = 86400000;
-
// MULTIPLY, THEN ADD TO CURRENT TIME
-
date.setTime(date.getTime() + (days * milliseconds));
-
// SET EXPIRATION VARIABLE
-
var expires = '; expires=' + date.toGMTString();
-
// CONCATENATE TO CREATE COOKIE
-
document.cookie = name + '=' + val + expires + '; path=/';
-
}
-
window.onload = function(){
-
if(document.referrer != ''){
-
// DESTROY ANY PREVIOUS DUPLICATE COOKIE
-
setCookie('referrer','',-1);
-
// CREATE COOKIE ON REGISTRATION PAGE
-
setCookie('referrer',document.referrer,1);
-
}
-
}
-
</script>
-
Then on your thank-you page, read the cookie value, and set the redirect URL with this code in the <head>: -
<script type="text/javascript">
-
// RETURN VALUE
-
var ret = null;
-
// MILLISECONDS (10 SECONDS)
-
var t = 10000;
-
// READ COOKIE FUNCTION
-
function getCookie(cookiename){
-
-
// ANY / ALL COOKIES
-
var docCookie = document.cookie;
-
-
// CHECK TO SEE IF A COOKIE EXISTS
-
if(docCookie.length > 0){
-
-
// CONCATENATE NAME AND ASSIGNMENT OPERATOR
-
cookiename += '=';
-
-
// WHERE THE COOKIE NAME IS LOCATED
-
var cookiestart = docCookie.indexOf(cookiename);
-
-
// IF IT EXISTS
-
if(cookiestart != -1) {
-
-
// ADD START POSITION AND NAME LENGTH
-
cookiestart += cookiename.length;
-
-
// FIND END OF STORED VALUE
-
var cookieend = docCookie.indexOf(';', cookiestart);
-
-
// IF SEMICOLON IS NOT FOUND
-
if(cookieend == -1){
-
// CORRECT LENGTH
-
cookieend = docCookie.length;
-
}
-
-
// RETURN COOKIE VALUE
-
return unescape(docCookie.substring(cookiestart, cookieend));
-
}
-
}
-
-
// RETURN NULL IF NO COOKIE IS FOUND
-
return null;
-
}
-
// REDIRECT FUNCTION
-
function backToReferrer(){
-
// GET COOKIE
-
var url = getCookie('referrer');
-
// INITIATE PAGE JUMP
-
window.location.href = url;
-
}
-
window.onload = function(){
-
// AFTER 10 SECONDS, CALL REDIRECT FUNCTION
-
ret = setTimeout('backToReferrer()', t);
-
}
-
</script>
-
You must make sure the person doesn't directly enter the URL of the registration page directly into an address bar, or comes from a bookmark. The document.referr er only works on a legitimate page jump.
hi ...
you may pass it through a query-string that you append to the url:
- whatever_url_you_have?referer=referal_url
in a webpage you retrieve the url with:
- var url = window.location.href
and from that you may retrieve the query-string and the referal_url.

So in my meta refresh tag, how do I reference the variable url?
[HTML] <meta http-equiv="refresh" content="2;url= +url+"> ??[/HTML]
Or like this? - <script type="text/javascript">
-
var name = "www.mysite.com"
-
document.write(name)
-
document.write("<meta http-equiv="refresh" content="2;url=+name+">)
-
</script>
Thanks - Tony
Thanks for the cookie example - I will give that a try.... Tony
The cookie worked great!!!
You are a genius.

Glad to hear it worked!
You could also improve the script by determining if the user has cookies disabled in his/her browser. That way, you could even dynamically give them instructions on how to turn cookies on for several browsers. I usually support 3 or 4 different browsers (Firefox 1.5+, MSIE6+, Opera 8+, and now Safari 3+ since it's available for Windows).
On your first page, the Registration page, you can place this code in the window.onload function: -
window.onload = function(){
-
// FAKE TESTING COOKIE
-
document.cookie = 'testing=123';
-
// IF COOKIE DIDN'T SET
-
if(document.cookie.indexOf('testing=') == -1){
-
// INSTRUCT THE USER TO ENABLE COOKIES
-
alert('You must enable cookies to continue!');
-
}
-
// ELSE, SET COOKIE
-
else {
-
// IF REFERRER
-
if(document.referrer != ''){
-
// DESTROY ANY PREVIOUS DUPLICATE COOKIE
-
setCookie('referrer','',-1);
-
// CREATE COOKIE ON REGISTRATION PAGE
-
setCookie('referrer',document.referrer,1);
-
}
-
// REFERRER ERROR
-
else {
-
// INSTRUCT USER TO NAVIGATE FROM MAIN PAGE
-
alert('You must come directly from our afilliate websites only!');
-
}
-
}
-
}
-
You can replace the alerts with custom code. You could have a <div> with style="display: none;" in the <body> section of the page, and then set the display to block by Javascript. The div could have graphics and text instructions magically appear...showin g the user what to do.
(I use alerts for testing, but never for a public web page!)
