jquery实现cookie存取值

//设定Cookie值
function SetCookie(name, value) {
var expdate = new Date(); var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null; var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false; if (expires != null) expdate.setTime(expdate.getTime() + (expires * 1000));
document.cookie = name + "=" + escape(value) + ((expires == null) ? "" : ("; expires=" + expdate.toGMTString()))
+ ((path == null) ? "" : ("; path=" + path))
+ ((domain == null) ? "" : ("; domain=" + domain))
+ ((secure == true) ? "; secure" : "");
}

//取Cookie值
function GetCookieVal(offset)//获得Cookie解码后的值
{
var endstr = document.cookie.indexOf(";", offset);
if (endstr == -1)
endstr = document.cookie.length;
return unescape(document.cookie.substring(offset, endstr));
}
