ASP 里设置了COOKIES JS里删除不了，求助

response.Cookies("Pusername")=userid
response.Cookies("Pusername").Expires= DateAdd("h",1,Now())

这里设置

这里删除

function exitlog(){
 alert("退出成功");
 delCookies("Pusername");
}

function delCookies(name)//删除cookie 
{ 
  var exp = new Date(); 
  exp.setTime(exp.getTime() - 1); 
  var cval=getCookie(name); 
  if(cval!=null) document.cookie= name + "="+cval+";expires="+exp.toGMTString(); 
} 

VBScript code

Response.Cookies("Pusername") = ""
Response.Cookies("Pusername").Expires= (now()-1) 

你好，我需要用JS 删除COOKIES

JScript code

function delCookie(name){
   var date = new Date();
   date.setTime(date.getTime() - 10000);
   document.cookie = name + "=a; expires=" + date.toGMTString();
}
