localStorage与sessionStorage 的区别

通过一枚页面计数器来区别localStorage与sessionStorage。

通过一个计数变量pageconut，每刷新页面，增加的是localStorage的数量，而sessionStorage只记录当前访问数量；

<!DOCTYPE html>

<html>

    <head>

        <meta charset="UTF-8">

        <meta http-equiv="content-type" content="text/html;charset=gb2312" />

        <title>页面访问数</title>

    </head>

    <body>

        <script>

            if(localStorage.pagecount){

                localStorage.pagecount = Number(localStorage.pagecount) + 1;

            }else{

                localStorage.pagecount = 1;

            }

            document.write('总访问数：' + localStorage.pagecount);

            if(sessionStorage.pagecount){

                sessionStorage.pagecount = Number(sessionStorage.pagecount) + 1;

            }else{

                sessionStorage.pagecount = 1;

            }

            document.write('当前访问数：' + sessionStorage.pagecount);

        </script>

    </body>

</html>
