Jade模板布局不能与Node.js结合使用 [英] Jade template layouts not working in combination with Node.js

问题描述

我试图在Node.js中创建一个使用Jade模板和布局的简单服务器。
由于某种原因，它只会加载模板而不是布局。

I'm trying to create a simple server in Node.js which uses Jade templates and layouts. For some reason it will only load the template and not the layout.

这是我所得到的：

main.js

var express = require('express');

var app = express.createServer();

app.set('views', __dirname + '/views'); 
app.set('view engine','jade');
app.set('view options', {
 layout: true
});

app.get('/', function(req,res) {
res.render('index', { title: 'My site' });
});

app.listen(4000);

正如您可以看到布局已启用。我已经尝试直接在render方法中引用它，但它没有什么不同。值得注意的是，标题：我的网站也不起作用。

As you can see layouts are enabled. I've tried referencing it directly in the render method but it doesn't make a difference. Worth noting might also be that the "title: 'My site'" doesn't work either.

index.jade

h2 Hello!
p I really hope this is working now

lo.jade

!!! 5
html
  head
    title Why won't this work
  body
    h1 I AM A LAYOUT
    div= body

这是我的 npm列表：

├─┬ express@3.0.0alpha1 
│ ├── commander@0.5.2 
│ ├─┬ connect@2.1.2 
│ │ ├── crc@0.1.0 
│ │ ├── formidable@1.0.9 
│ │ ├── mime@1.2.4 
│ │ └── qs@0.4.2 
│ ├── debug@0.6.0 
│ ├── mime@1.2.5 
│ └── mkdirp@0.3.1 
└─┬ jade@0.24.0 
  ├── commander@0.5.2 
  └── mkdirp@0.3.0 

任何想法，为什么这不工作？

Any ideas on why this isn't working?

推荐答案

我想你在做布局错误的方法。我这样做：

I think you're doing layout the wrong way. I do it this way :

我将布局设置为false：

I set layout to false :

app.set('view options', {
    layout: false
});

在layout.jade文件中：

In a layout.jade file :

doctype 5
html(lang="en")
    head
        title MySite #{title}
body
    block mainContent

在渲染页面（让我们说：home.jade），其中包含一个变量（content）

And in the rendered page (let's say : home.jade), which include a variable (content)

extends layout

block mainContent
    h1 This is home
    p= content

您可以根据（扩展）具有不同变量的相同布局（other.jade） （用户）

You could have another page based on (extending) the same layout (other.jade) with different variables (user)

extends layout

block mainContent
    h1 Oh look ! Another page
    p= user

并像下面这样调用：

app.get('/', function(req, res) {
    res.render('home', { 
        title : "Home",
        content: "Some Home page content"
    });
});

app.get('/anotherPage', function(req, res) {
    res.render('other', { 
        title : "Other page",
        user: "Here goes a user name"
    });
});
