Retrieve random value from local storage

is possible to retrieve. print and then delete one random value from localstorage?

      var data = jQuery.parseJSON(data);

      data.forEach(function(dataItem){

          var id = dataItem.id;
          var orario = dataItem.orario;
          var casa = dataItem.casa;
          var trasferta = dataItem.trasferta;
          var matches = "<span id='matches_text'>"+orario+"</span> "+casa+" <br> "+trasferta+"";

          localStorage.setItem("matches_"+id+"", ""+matches+"");

          var matches = localStorage.getItem("matches_"+id+"");

      });

thanks
