Cookie Java Script Not Working. Help please.

[Shadiman]

Dear All,

I am new to Java and Java Script.

I have a need to read a cookie and update the expiry date on a particular cookie; so I have written the following;

function Update_Cookie(){
// Write a set of cookies

document.cookie = "Session_Tolken=123"
document.cookie = "First_name=Shad"
document.cookie = "Second_name=Mortazavi"

// Script
var expireDate = new Date
expireDate.setSeconds(expireDate.getSeconds()+60)

var cookieName
var cookieValue
IfaceCookie = document.cookie.split(";")
document.write (IfaceCookie + "<BR>")
for (var i = 0; i < IfaceCookie.length; i++)
{
var cookieName = IfaceCookie.split("=")[0];
var cookieValue = IfaceCookie.split("=")[1];

document.write ("i = "+i+" CookieName ="+cookieName +"<BR>")

if (cookieName == 'Session_Tolken')
{
alert ('in')
document.cookie = "Session_Tolken="+cookieValue+";expires="+expireDate;
}
}

}

This works if the cookies are writtent in the order specified above, it breaks if I change the order in which the cookie is written?

document.cookie = "First_name=Shad"
document.cookie = "Session_Tolken=123"
document.cookie = "Second_name=Mortazavi"

The stange think is that the write statment in the script indicates that eveything is OK;

First_name=Shad, Session_Tolken=123, Second_name=Mortazavi
i = 0 CookieName =First_name
i = 1 CookieName = Session_Tolken
i = 2 CookieName = Second_name

I'm sure I am missing something obvious.

The problem was caused by a leading space in the variable depending on where in the cookie the value pair was.

I have re-writtent the script;

function Update_Cookie(){
// Write a set of cookies

document.cookie = "Session_ID=15"
document.cookie = "First_name=Shad"
document.cookie = "Session_Tolken=123"
document.cookie = "Second_name=Mortazavi"

var expireDate = new Date
expireDate.setSeconds(expireDate.getSeconds()+60)

var cookieName
var cookieValue

IfaceCookie = document.cookie.split(";")
document.write (IfaceCookie + "<BR>")
for (var i = 0; i < IfaceCookie.length; i++)
{
var cookieName = IfaceCookie.split("=")[0];
var cookieValue = IfaceCookie.split("=")[1];

// Work out if there is a session tolken
// Cookies may have a space at the start

if (cookieName == ' Session_Tolken' || cookieName =='Session_Tolken')
{
document.cookie = "Session_Tolken="+cookieValue+";expires="+expireDate;
} else if (cookieName == ' Session_ID' || cookieName =='Session_ID')
{
document.cookie = "Session_ID="+cookieValue+";expires="+expireDate;
}
}


}
