------解决方案--------------------
常用的3个方法

function SetCookie(sName, sValue)
{
document.cookie = sName + "=" + escape(sValue);
var date = new Date();
date.setMonth(date.getMonth()+1);
document.cookie += ("; expires=" + date.toUTCString()); 
}
function GetCookie(sName)
{
var aCookie = document.cookie.split("; ");
for (var i=0; i < aCookie.length; i++)
{
// a name/value pair (a crumb) is separated by an equal sign
var aCrumb = aCookie[i].split("=");
if (sName == aCrumb[0]) 
return unescape(aCrumb[1]);
}
// a cookie with the requested name does not exist
return null;
}

function DelCookie(sName)
{
document.cookie = sName + "=; expires=Fri, 31 Dec 1999 23:59:59 GMT;";
}
