Here is a class based on scripts at quirksmode.org, just needs to be
ported to jQuery. If nobody does it, I will make a plugin out of it:
var CookieHandler = new function() {
/**
* Reads a cookie.
*
* @param name the name of the cookie
*
* @return the value of the cookie
*
* @author Klaus Hartl (28.06.2006)
*/
this.get = function(name) {
var nameEQ = name + '=';
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i];
while (c.charAt(0) == ' ') {
c = c.substring(1, c.length);
}
if (c.indexOf(nameEQ) == 0) {
return c.substring(nameEQ.length, c.length);
}
}
return null;
};
/**
* Sets a cookie with the given name and value and other optional
parameters.
*
* @param name the name of the cookie
* @param value the value of the cookie
* @param expires an integer specifying the expiration date from
now on
* in days. If you set the number of days to 0 the
cookie
* is trashed when the user closes the browser.
* @param path path where the cookie is valid (default: path of
* calling document).
* @param domain domain where the cookie is valid (default: domain of
* calling document).
* @param secure boolean value indicating if the cookie transmission
* requires a secure transmission.

*/
this.set = function(name, value, expires, path, domain, secure) {
if (typeof expires == 'number') {
var date = new Date();
date.setTime(date.getTime() + (expires * 24 * 60 * 60 * 1000));
expires = '; expires=' + date.toGMTString();
} else {
expires = '';
}
path = (path) ? '; path=' + path : '';
domain = (domain) ? '; domain=' + domain : '';
secure = (secure) ? '; secure' : '';
document.cookie = name + '=' + value + expires + path + domain
+ secure;
};
/**
* Deletes a cookie by setting the expiry date in the past.
*
* @param name the name of the cookie
*
* @author Klaus Hartl (28.06.2006)
*/
this.erase = function(name) {
this.set(name, '', -1);
};
};
