B页面获取数据并显示

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>用户信息</title>
</head>
<style>
    body{
        margin: 0 auto;
        width: 1060px;
        text-align: center;
    }
    h2{
        text-align: center;
    }
</style>
<body>

<h2>用户信息</h2>
<script>
    //获取信息
    var _data = localStorage.getItem("data", _data);

    if (localStorage.getItem("data") != null) {
         _data = _data.split(",");
        document.write("用户名:");
        document.write("<br>");
        document.write(_data[0]);
        document.write("<br>");
        document.write("密码:");
        document.write("<br>");
        document.write(_data[1]);
        document.write("<br>");
        document.write("邮箱:");
        document.write("<br>");
        document.write(_data[2]);
        document.write("<br>");
        document.write("座机号:");
        document.write("<br>");
        document.write(_data[3]);
        document.write("<br>");

        //清空数据
        localStorage.removeItem("data");
      }else{ 
              alert('数据不存在，请登录')
      }

</script>
</body>
</html>

这个也可以归结为是localStorage的使用方法来解决的，很困了，先写这么多了。
