Example
var name = name + "=",
cookie_array = document.cookie.split(';'),
cookie_value;
for(var i=0;i<cookie_array.length;i++) {
var cookie=cookie_array[i];
while(cookie.charAt(0)==' ')
cookie = cookie.substring(1,cookie.length);
if(cookie.indexOf(name)==0)
cookie_value = cookie.substring(name.length,cookie.length);
}
This will set cookie_value to the value of the cookie, if it exists. If the cookie is not set, it will set cookie_value to null
