推荐使用：
//根据名称获取Cookie
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i].trim();
if (c.indexOf(name) == 0) return c.substring(name.length, c.length);
}
return null;
};
//设置Cookie； 参数cname名称，cvalue值，exdays天数
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
var expires = "expires=" + d.toGMTString();
document.cookie = cname + "=" + cvalue + "; " + expires + ";path=/;domain=.xxxxx.com";
};
//使用时一定要修改 .xxxxx.com 为你的域名， 如www.baidu.com 改为.baidu.com常规操作
function setCookie(cname,cvalue,exdays){
var d = new Date();
d.setTime(d.getTime()+(exdays*24*60*60*1000));
var expires = "expires="+d.toGMTString();
document.cookie = cname+"="+cvalue+"; "+expires;
}
function getCookie(cname){
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) {
var c = ca[i].trim();
if (c.indexOf(name)==0) { return c.substring(name.length,c.length); }
}
return "";
}
function checkCookie(){
var user=getCookie("username");
if (user!=""){
alert("欢迎 " + user + " 再次访问");
}
else {
user = prompt("请输入你的名字:","");
if (user!="" && user!=null){
setCookie("username",user,30);
}
}
}跨域访问cookie （仅支持二级域名）
参考：javascript跨域设置cookie（二级域名）_xuebingnan的博客-CSDN博客
function setCookie(c_name, value, expiredays) {
var exdate = new Date();
exdate.setDate(exdate.getDate() + expiredays);
document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ? "" : ";expires=" + exdate.toGMTString() + ";path=/;domain=.testdomain.com")
}
var AdTime = new Date();
if (AdTime != "") {
setCookie("AdTime", AdTime, 1);
}
