求SetCookie(name,value),GetCookie(name)两函数。。。

求SetCookie(name,value),GetCookie(name)两函数。。。
要求:
如有http://www.xxx.com/a.html,http://www.xxx.com/second/b.html
a页面里调用SetCookie("abc","ok"),b页面里调用GetCookie("abc")能得到"ok";
同理，在b页面里调用SetCookie("cde","no"),a页面里调用GetCookie("cde")能得到"no";
如同Session一样在同一域下作用是相同的。
同发在：http://topic.csdn.net/u/20071113/14/a93e6285-1d55-422e-9edd-3850f80a10cc.html

试试下面代码,应该没问题

function getcookie(name)
{
  var cookief=false;
  var start=0;
  var end=0;
  var cookiestr=document.cookie;
  var i=0;
  while(i<=cookiestr.length)
  {
    start=i;
    end=start+name.length;
    if(cookiestr.substring(start,end)==name)
    {
      cookief=true;
      break;
    }
    i++;
  }
  if(cookief)
  {
   start=end+1;
   end=cookiestr.length;
   return unescape(cookiestr.substring(start,end));
  }
  return "";
}
function setcookie(name,value)
{
  var exp=new Date();
  exp.setYear(exp.getYear()+1);
 //编码：escape();unescape 解码
  document.cookie=name+"="+escape(value)+";expires="+exp.toGMTString();
}

原来没设置好path
把path=/
就可以的。
