下面这个就是他的cookie，与前面的比就是将cookie的值 串成 key：value&key：value的形式。这样做有什么用吗？
这与我直接设置 某一个listproductcookie 的值 为： productlistcookie=name:jsh&pwd:jsh&key:value.这样不是一样吗？
还有这里用“：”会不会产生错误的？不过，我测试过是不会的。
请问这样操作cookie好吗？
还是用jquery 插件好？

写成 productlistcookie=name:jsh&pwd:jsh&key:value
取的时候适当拆分
而且他这个要先加载然后再存储的
# function addCookie(name,value,expireHours){
# var CookieStr=name+"="+escape(value);
# if(expireHours>0){
# var date=new Date();
# date.setTime(date.getTime()+expireHours*3600*1000);
# CookieStr=CookieStr+";expire="+date.toGMTString();
# }
# document.cookie=CookieStr;
# }
# function getCookie(name){
# var strCookie=document.cookie;
# var arrCookie=strCookie.split(";");
# for(var i=0;i<arrCookie.length;i++){
# var arr=arrCookie[i].split("=");
# if(arr[0]==name){
# return arr[1];
# }
# return "";
# }
# }
jquery当然是比较简单些，兼容性也好
题外话啦。。
谢谢大家
我觉得用jQuery方便多了..而且兼容要很多的。。
都可有优点吧，cookie本来长度都有限制，加在一起，更容易超出长度限制了
另一方面cookie 中key的个数也有限制，这样又有好处
more detail
sky 有给了我另一个问题的答案啦。。谢谢
