我试图使用提示让某人输入值，将该值变为cookie，然后有一个链接将该人重定向到第二个页面，其中将显示其cookie值。我遇到的问题是，无论我输入什么，所涉及的cookie都会继续返回null。任何帮助，将不胜感激！Cookie值始终返回null
这是为了成为一个Javascript代码。

if (days) {
var date = newDate();
date.setTime(date.getTime() + (days*24*60*60*1000));
var expires = date.toGMTString();//code
}
else var expires = "";
cookieString = name + "=" + escape(value);

document.cookie = cookieString

var nameEquals = name + "=";
var crumbs = document.cookie.split(';');
for (var i = 0; i < crumbs.length; i++) {
var crumb = crumbs[i];
if (crumb.indexOf(nameEquals) == 0) {
return unescape(crumb.substring(nameEquals.length, crumb.length));
