I cannot get this code to work I must be missing something pretty simple. I am trying to check to see if a Cookie exists, if it does {do nothing} if it doesn't {create it}. I am testing the cookie by including an alert on a page. Basically I do not want the cookie to keep re-creating with a referral url, I am trying to grab only the FIRST referred URL.

$(document).ready(function(){   
  if ($.cookie('bas_referral') == null ){
   var ref = document.referrer.toLowerCase();  
   // set cookie  
   var cookURL =  $.cookie('bas_referral', ref, { expires: 1 }); 
  } 
 });

Displaying the current cookie contents:

    // get cookie  
    alert($.cookie('bas_referral'));  

    // delete cookie  
     $.cookie('bas_referral', null);
referrer if-statement isnull cookies jquery

Try this very simple:

            var cookieExist = $.cookie("status");
            if(cookieExist == "null" ){
                alert("Cookie Is Null");

            }
