Hi
I am trying to make a cookie based redirect system. The plan was in a 3 page sequence, the first two pages will check if the cookies exist and if they do they will be relocated (replace) to cookie.htm. If there is not a cookie the person will be allowed to view the page. On the last page the JS engine will write a cookie so that the said person can not do the process again. I tested the system out with these codes and either the cookies were never made or the readers did notread the cookies.
EXPIRATION DATE=2 days or Dec 1st 2012 at noon EST
Reader:
var cname = "vote"
var data ="1";
var cpath = "";
var cdomain = "";
function CheckForCookie()
{
if( ExistsCookie(cname) )
{
window.location.replace("cookie.htm")
}
}
Writer:
var cname = "vote"
var data ="1";
var cpath = "";
var cdomain = "";
// Checks whether the form should be submitted or not
// If the cookie exists, the form is not submitted
// if no cookie exists, a new cookie, set to expire after
// three months ,is written and the form is submitted
function CheckCookie()
{
if( !ExistsCookie(cname) )
{
// Write a cookie set to expire after 2 days
now= new Date(); // get current date and time
expiry = new Date();
expiry.setTime((now.getTime() + 2*24*60*60*1000)); // set to 2 days from now
WriteCookie(cname,data,expiry,cpath,cdomain); // Write cookie
return true;
}
alert("You have already submitted this form");
return false;
}
//Writes the specified data to the cookie file
function WriteCookie(name,data,expiryDate,path,domain)
{
if( name==null || name=="" || data==null || data=="")
{
return false;
}
var Cookie = name + "=" + escape(data)
+ ( (expiryDate)? "; expires=" +
expiryDate.toGMTString() : "" );
+ ((path)? "; path=" + path : "" )
+ ((domain)?"; domain=" + domain : "" );
Cookie +=";";
//Set cookie
document.cookie = Cookie;
return true;
}
//Checks if the specified cookie exists or not
function ExistsCookie(name)
{
// cookies are separated by semicolons
var aCookie = document.cookie.split("; ");
for (var i=0; i < aCookie.length; i++)
{
// a name/value pair is separated by an equal sign
var aCrumb = aCookie[i].split("=");
if (name == aCrumb[0])
return true;
}
// a cookie with the requested name does not exist
return false;
}
What am I doing wrong? PLEASE help me!
