html5本地存储（仅仅记录自己已经用到的知识）

　　　存储数据：

            window.localStorage.setItem('key', score1);
            window.localStorage.setItem('key1', zhi1);
            window.localStorage.setItem('key2', zhi2);
            window.localStorage.setItem('key3', zhi3);

          获取数据：

         var score1 = localStorage.getItem(localStorage.key(0));
         var zhi1 = localStorage.getItem(localStorage.key(1));
         var zhi2 = localStorage.getItem(localStorage.key(2));
         var zhi3 = localStorage.getItem(localStorage.key(3));
