动态设置元标签EJS
我正在使用EJS，我需要为每个帖子设置元标记。我在layouts文件夹中有样板，我将其包含在每个页面中。当用户进入帖子页面时，我需要设置动态元标记和标题。我的样板
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<%= title %>
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<link rel="stylesheet" href=".11.2/css/all.css">
<link rel="stylesheet" href=".3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
<link rel='stylesheet' href='/stylesheets/style.css' />
</head>
<body>
<% include ../partials/navbar.ejs %>
<div class="container-fluid">
<% include ../partials/filter.ejs %>
<div class="row">
<div class="col-sm-12 col-lg-10">
<%- body -%>
</div>
<div class="col-sm-12 col-lg-2">
<% include ../partials/sidebar %>
</div>
</div>
</div>
</body>
</html>
我正试图通过这种方式将标题传递给帖子页面
res.render('post/index', {title: post.meta.title, post: post});
但是我有一个错误，即标题没有在样板中定义；
回答如下：如果我正确理解了问题，我为您制作了一个样本。
帖子的猫鼬模式
const postScheme = new Schema({
"title": String,
"description": String, // meta description
"robots": String, // index or noindex
"lang": String, // en, fr, tr
"pathname": String, // post-pathname
"main": String // post body content
})
获取帖子数据并进行渲染。
Post.findOne({ _id: req.params.id }, (err, data) => {
res.render('post/index', { 'data': data })
}).lean()
并编辑.ejs文件。
<!doctype html>
<html lang="<%= data.lang %>">
<head>
<meta charset="UTF-8">
<title> <%= data.title %> </title>
<meta name="description" content=" <%= data.description %> "/>
<link rel='stylesheet' href='/stylesheets/style.css' />
</head>
<body>
<% include ../partials/navbar.ejs %>
<div class="container-fluid">
<% include ../partials/filter.ejs %>
<div class="row">
<div class="col-sm-12 col-lg-10">
<%- data.main %>
</div>
<div class="col-sm-12 col-lg-2">
<% include ../partials/sidebar %>
</div>
</div>
</div>
</body>
</html>
