Changing cookie expiration

I am running a script that currently sets a cookie that expires at the end of the session when the browser close's. I would like to set the expiration date for 360 days. Not sure how to make this change in the following code:

      setCookie:function(name, value, days){
       var expirestr=''
       if (typeof days!="undefined") //if set persistent cookie
       expirestr="; expires="+expireDate.setDate(new Date().getDate()+days).toGMTString()
       document.cookie = name+"="+value+"; path=/"+expirestr
      }

get the old value first (getCookie(c_name)) and recreate (setCookie:function(name, value, days)) it with the new expiration date :)

So modification to this string will not do the trick?

expirestr="; expires="+expireDate.setDate(new Date().getDate()+days).toGMTString()

Okay I'm following you somewhat... I'm deconstucting this to learn. I think I should have included the entire routine: This is not as clear cut as I thought it was. The cookies name is fluidtextresizer. So by calling the old value (if it is available) first... then set the expiration date?

fluidtextresizer.routines={
      getCookie:function(Name){
      var re=new RegExp(Name+"=[^;]*", "i"); //construct RE to search for target name/value pair
      return (document.cookie.match(re))? document.cookie.match(re)[0].split("=")[1] : null //return cookie value if found or null
      },

      setCookie:function(name, value, days){
      var expirestr=''
      if (typeof days!="undefined") //if set persistent cookie
      expirestr="; expires="+expireDate.setDate(new Date().getDate()+days).toGMTString()
      document.cookie = name+"="+value+"; path=/"+expirestr
      }
}

yes, if it not exist you're just creating a cookie with a null value

Yeah I'm not getting it... Can't seem to adapt your recommendations into the code I have and get it to work.... The principle makes sense, application does not...

I guess the crazy part is I can get the simple application to work but this script is a little more complicated. Complete script attached... fluidtextresizer.js

Still plugging away... still not able to make the leap...

If you place alert/console.log as first command of setCookie and getCookie do you get/see them ?

As you tell by now, I'm not real adept with JavaScript... I tried the following but it throws and error:

alert( document.cookie("fluidtextresizer") );

Using FF cookie viewer I am able to view the values and can see whether my modifications are working. I've been able to create a simple cookie separate from the script I attached. I am forced to use this script but have not been able to make the leap....
