您的代码中几乎没有错误。

在answers.html中，您必须在末尾提及脚本部分（不在 中<head>）。否则，脚本将首先执行，当您从 localStorage 获取项目时，您将获得空值。

  <!DOCTYPE html>
    <html>
    <head>

        <title>Result</title>

    </head>
    <body>


     congretulations!.. <span id="maitrik">Hello</span>

    </body>
    </html>

<script type="text/javascript">

        document.getElementById('maitrik').innerHTML=localStorage.getItem('textvalue');

     </script>

然后您还没有制作带有 id ='results' 的标签来打印标记。完成后，您将获得预期的结果。

谢谢你。
