[Duquan]

How to make sure that when the pieces are empty, count() Did you get 0, not one?

Cooks shall be stored in such a way as 4.3.2. 4%2C3%2C2%2C1 )

var fav = $.cookie('favorites');
fav = fav.split(","); 
$('.cookie_text').html(fav + " = <span id='wer'>" + count(fav) + "</span>");

Function count():

function count(array) {

var cnt=0;

for (var i in array){

if (i){ cnt++ }

}

return cnt

}

Function https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Global_Objects/String/split Always returning the mass with at least one element. This time.
Two, I don't know what your function is. countIf she was given a mass at the entrance, you could just take his properties. https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Global_Objects/Array/length ♪

There may be several options, for example

1. check that fav empty line, so there's no doll.

   var fav = $.cookie('favorites');
   $('.cookie_text').html(fav + " = <span id='wer'>" + count(fav) + "</span>");
   function count(array){
   
   if(array==='') return 0;
   
   return array.split(',').length;
   
   }
   
   

2. https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Global_Objects/Array/filter to remove elements with an empty line

   var fav = $.cookie('favorites');
   
   fav = fav.split(",");
   
   $('.cookie_text').html(fav + " = <span id='wer'>" + count(fav) + "</span>");
   
   function count(array){
   
   return array.filter(function(el){
   
   return el != '';
   
   }).length;
   
   }
