分享JS 文件不能得到COOKIE 的问题！！！
我现在所做的项目首页页面头的导航部分是是用JS 文件写的，当我登录并将用户信息写入COOKIE 中后，凡是通过导航部分打开的页面均不能得到COOKIE 值，但是注销以后第二次登录，却一切正常了，真不知道是什么原因。

JS 对 cookie 操作
function setCookie(name,value)
{
var Days = 30; //此 cookie 将被保存 30 天
var exp = new Date(); //new Date("December 31, 9998");
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function getCookie(name)
{
var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)");
if(arr=document.cookie.match(reg)) return unescape(arr[2]);
else return null;
}
function delCookie(name)
{
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}
function setCookie(name,value)
{
var Days = 30; //此 cookie 将被保存 30 天
var exp = new Date(); //new Date("December 31, 9998");
exp.setTime(exp.getTime() + Days*24*60*60*1000);
document.cookie = name + "="+ escape (value) + ";expires=" + exp.toGMTString();
}
function getCookie(name)
{
var arr,reg=new RegExp("(^| )"+name+"=([^;]*)(;|$)");
if(arr=document.cookie.match(reg)) return unescape(arr[2]);
else return null;
}
function delCookie(name)
{
var exp = new Date();
exp.setTime(exp.getTime() - 1);
var cval=getCookie(name);
if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}

我现在不是要在JS 中得到COOKIE值，而是说页面中引用的JS文件中的链接打开的页面，COOKIE 会无故丢失（也许不是无故吧！而是我不知道）。
