复制过去直接运行吧

cookie对于IE浏览器可以直接访问，对于谷歌内核类似的浏览器要开启服务器访问。
// writeCookie("myCookie", "my name", 24);
// Stores the string "my name" in the cookie "myCookie" which expires after 24 hours.
// The hours parameter is optional; if hours is left out, the cookie value expires at the end of the visitor's browser session.
function writeCookie(name, value, hours)
{
var expire = "";
if(hours != null)
{
expire = new Date((new Date()).getTime() + hours * 3600000);
expire = "; expires=" + expire.toGMTString();
}
document.cookie = name + "=" + escape(value) + expire;
}
// Example:
// alert( readCookie("myCookie") );
function readCookie(name)
{
var cookieValue = "";
var search = name + "=";
if(document.cookie.length > 0)
{
offset = document.cookie.indexOf(search);
if (offset != -1)
{
offset += search.length;
end = document.cookie.indexOf(";", offset);
if (end == -1) end = document.cookie.length;
cookieValue = unescape(document.cookie.substring(offset, end))
}
}
return cookieValue;
}追问不要复制些没用的东西上来回答，针对问题回答。追答两个方法：一个写cookie，一个读cookie，难道你还看不懂么？？？？要知道你这么菜，我就不回答你的问题了
