我正在为我的学校使用 Powerschool 数据库。这是一家非营利性教育机构，它使用 SIS 来保存学生信息、成绩等。我需要这个网页在每周的每个星期五自动通过电子邮件发送到所有家长的电子邮件帐户。父母的电子邮件帐户已在 SIS 上的用户配置文件中设置。

有没有办法让用户在这个网页上提交他们的电子邮件地址，然后使用 Javascript 自动安排这个网页在每周的每个星期五通过电子邮件发送给用户？

对于购物清单，我真的很抱歉，但我对 JavaScript 的了解非常有限。

这是我显示学生成绩的基本 HTML 页面。当学生和家长登录到他们在 Powerschool（我的 SIS）中的个人资料时，它就会起作用。
