Javascript 验证电子邮件表单在IE中不起作用

我试图构建一个表单，在选中复选框后验证字段。它在除IE之外的所有浏览器中都能正常工作。对在IE中也能正常工作有什么建议吗

JavaScript可能已经失控了，但我对它的编程非常陌生，还有很多东西需要学习。 谢谢你的帮助，如果有更好的方法写这篇文章，我愿意接受每一个建议

**这里是对正在运行的表单的更新

您似乎还不熟悉使用Javascript/jQuery验证表单

我建议使用jQuery插件，如jQuery.validate来验证表单前端。该插件将确保验证工作跨浏览器，包括Internet Explorer

建议的条款：

---

另外，别忘了前端是验证，这只是战斗的一半，你还需要验证后端！为确保传递到表单数据处理脚本的数据的安全性和有效性。

请您更具体地说，什么是无效的？在IE中按下提交按钮时，会打开一封没有内容的电子邮件，但在Firefox、Opera和Chrome中按下提交按钮时，电子邮件会填充所有信息字段。
