问是否可以通过查看设置的cookie来判断用户是否登录到Wordpress？

EN

<script type="text/javascript">
function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{
  x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
  y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
  x=x.replace(/^\s+|\s+$/g,"");
  if (x==c_name)
    {
    return unescape(y);
    }
  }
}

var logged_in=getCookie("wordpress_logged_in_[HASH]");
  if (logged_in!=null && logged_in!="")
  {
  alert("You are logged in!");
  }
else
  {
   alert("You are logged out!");
  }
</script>
