node.js中Jade模板的全局變量

Question

我正在使用node.js和Jade模板系統。

假設，我有這些路由規則：

// ./routes/first.js 

exports.first = function(req, res) 
{ 
    res.render('first', { 
     author: 'Edward', 
     title: 'First page' 
    }); 
}; 

// ./routes/second.js 

exports.second = function(req, res) 
{ 
    res.render('second', { 
     author: 'Edward', 
     title: 'Second page' 
    }); 
}; 

而且這些虛擬的觀點：

// ./views/first.jade 

html 
    head 
     title #{author} – #{title} 
    body 
     span First page content 

// ./views/second.jade 

html 
    head 
     title #{author} – #{title} 
    body 
     span Second page content 

我怎樣才能申報一般author變量，這兩種觀點？

Answer 1

// ./author.js 
module.exports = 'Edward'; 

// ./routes/first.js 

exports.first = function(req, res) 
{ 
    res.render('first', { 
     author: require('../author'), 
     title: 'First page' 
    }); 
}; 

// ./routes/second.js 

exports.second = function(req, res) 
{ 
    res.render('second', { 
     author: require('../author'), 
     title: 'Second page' 
    }); 
}; 

或

// ./views/includes/head.jade 
head 
    title Edward – #{title} 

// ./views/first.jade 

html 
    include includes/head 
    body 
     span First page content 

// ./views/second.jade 

html 
    include includes/head 
    body 
     span Second page content 

或

// ./views/layout.jade 
html 
    head 
     title Edward – #{title} 
    body 
     block body 

// ./views/first.jade 

extends layout 
append body 
    span First page content 

// ./views/second.jade 

extends layout 
append body 
    span Second page content
