Question

我正在尝试开发一个存储用户名，国家和用户消息sin mongodb的留言簿应用程序，连接正常，我可以在数据库中提交这3个信息（用户名，国家和消息）。我的问题是将邮件转发到我的“guestbook.ejs”页面。

我很感激如果有人能就我遇到的问题给我一些线索。

Answer 1

代替

 <% include ../partials/head %>

写

<%- include ("../partials/head") %>

Answer 2

在<%})%>之前添加</table>或删除，因为您未关闭forEach

HTML评论不会影响ejs。您可以改为使用{# #}。

Answer 3

就我而言，我发现包含以下部分模板的错误

<% include ./partials/messages %>

所以我用以下内容更改

<%- include ('partials/messages') %>

对我有用，希望对您有帮助

Answer 4

删除代码中不必要的<％％>标记

在编译ejs时，意外的令牌返回
