localStorage 方法

localStorage 方法存储的数据没有时间限制。第二天、第二周或下一年之后，数据依然可用。

如何创建和访问 localStorage：

实例：

<script type="text/javascript">
localStorage.lastname="Smith";
document.write(localStorage.lastname);
</script>

下面的例子对用户访问页面的次数进行计数：

实例

<script type="text/javascript">
if (localStorage.pagecount)
  {
  localStorage.pagecount=Number(localStorage.pagecount) +1;
  }
else
  { localStorage.pagecount=1;
  }
document.write("Visits "+ localStorage.pagecount + " time(s).");
</script>

<script type="text/javascript"> localStorage.clear(); </script>
