如何在 ejs 中有条件地包含视图？

Question

I only want to show dashboard in my ejs template when my session variable person is not null or not undefined .

But it's just showing the dashboard every time. and in my log statement, the person value is undefined .

<%= console.log(person); %>
<% if (person !== null || person !== undefined) { %>
<%- include("dashboard"); %>
<% } else { %>
<%- include("login"); %>
<% } %>

What could be the proper way to do it?

Answer 1

I'm not sure but can you try changing the if statement to

<% if (person) { %>

It will simple return true if person is not null or undefined

Answer 2

它可以通过以下方式完成：

<%- include(person !== null && person !== undefined ? "dashboard" : "login"); %>
