现在要在登录的时候把用户名写到cookie里面，然后在别的页面把cookie读取出来，代码怎么写？

[KimSoft]

// Example:

// writeCookie("myCookie", "my name", 24);

// Stores the string "my name" in the cookie "myCookie" which expires after 24 hours.

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;

}

读取cookie：
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;
}
alert( readCookie("myCookie") );

写入cookie：
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;
}
writeCookie("myCookie", "my name", 24);
