session storage: the ammount of objects saved

Question

I am trying to get the amount of objects saved to a session storage element.

I need to find out how many tickets have been saved into session storage; tickets.

So far the code I have is;

$('#price').html(sessionStorage['tickets']);

I have tried sessionStorage.length['tickets']); and a few other variations to no avail. I am aware this is a simple request but have trawled the internet and haven't gotten far.

This function created sessionStorage tickets by passing a class into it.

function confirm(){
    var str="";
    if(!sessionStorage['user']){
          alert('You Must First Sign In or Register!');
         } else{
     if($(".tickets").length>0){
         $(".tickets").each(function(){
                str += this.id+" "; 
                sessionStorage.setItem('tickets', str);


               });
         } else {
          alert("You have not sellected any seats.");
         }
     //alert(""+sessionStorage['tickets']);
       window.location="index.php";
         }

}
