Usage:

<code lang="JavaScript">
Cookie.create("cookCookie", "ummm ... tasty cookie", 7); // creates a cookie
Cookie.create("cookie_two", "some value", 7); // creates another cookie
var cN = Cookie.allNames(); // returns an associative array with all the names of the cookie
var cO = Cookie.getNVpair(); // returns an object with cookie names and their respective values, the form in this case would be: Object > Object:cookCookie >> cookCookie["value"] = "ummm ... tasty cookie"; Object:cookie_two >> cookie_two["value"] = "some value"
for(var i in cO){
alert(Cookie.read(i));
}
Cookie.destroy("*"); // .. or ..
/*Cookie.destroy("cookCookie");
Cookie.destroy("cookie_two");*/
