Cookies

[wangers16]

Hi,

I have the following code for use in a cookie script that can change the stylesheet depending upon what the visitor has decided on, here it is

function getcookie(c_name)
{
if (document.cookie.length>0)
  {
  c_start=document.cookie.indexOf(c_name + "=");
  if (c_start!=-1)
    { 
    c_start=c_start + c_name.length+1 ;
    c_end=document.cookie.indexOf(";",c_start);
    if (c_end==-1) c_end=document.cookie.length
    return unescape(document.cookie.substring(c_start,c_end));
    } 
  }
return "vista"
}

I was wondering how I could get this to work through different browser sessions because at the moment it is reverting back to the original everytime the page is loaded

Thnks in advance

That is determined when the cookie is set. If you want a session cookie, don't specify a duration.

You're welcome in advance.

I have set a duration, however it is still only working with browser sessions

Here is the code that set's the cookie, if that is any help

function createCookie(c_name,value,expiredays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate()+expiredays);
document.cookie=c_name+ "=" +escape(value)+((expiredays==null) ? "" : "; expires="+exdate.toGMTString());
}

and this is the button used to activate the command

<input type="button" value="Login" onClick="createCookie('style','old','1000000');">

This suggests that when someone clicks a 'login' button, you're creating a fixed-value cookie, whereas you said initially that you're storing a user preference. I think you need to clarify exactly what happens and what you expect.

Well the script is supposed write a user preference value to a cookie and that cookie is then later read by the computer and writes out a predefined stylesheet onto the site.

Now this does happen but it only happens per a user session only, whereas I need it to be able to be read at any browser session without the need of having to choose which style to use every time.

You have shown no code that reads a user preference and writes it to a cookie.
You showed a Login button setting some cookie to a fixed value. If that's the same cookie, then obviously any value it stores is being reset whenever that button is clicked.
