我是javascript的新手,我在编写Cookie时遇到问题。这是我的代码
function writeCookie(name, value, days){
var cookie_expires;
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
cookie_expires = "; expires=" + date.toGMTString();
}
else {
cookie_expires = "";
}
document.cookie = name + "=" + value + cookie_expires;
}
然后如果我调用此函数
function check(){
alert("all cookies"+document.cookie);
}
它没有给我什么。有人能帮助我吗?

尝试使用这些函数来编写和获取cookie:
function setCookie(c_name,value,exdays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}
function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name)
{
return unescape(y);
}
}
}
