为什么我不能在玉器中找到app.locals

Question

我正在使用express/node/jade并为某些变量构建模块。

我在app.js app.locals.GVs = require('./utils/globalvars.js');

这条线，这是我的玉

extends ../layout 

block content 
    h1 Edit - Change Your Profile 
    p There will hopefully be a form to change users here. 
    form(id='form',action='') 
    include ./includes/user-form.jade 
    input(type='reset', value='Clear') 
    input(type='submit', value='Update') 
    script. 
    //Wait for document to load. 
    $(document).ready(function(){ 
     $('#firstname').val('#{data.firstname}'); 
     $('#lastname').val('#{data.lastname}'); 
     $('#username').val('#{data.username}'); 
     $('#phone').val('#{data.phone}'); 
     $('#email').val('#{data.email}'); 

     //Once form is submitted thisUserData (UserData) is created. 
     $('#form').submit(function(){ 
     // creates the variable thisUserData as a new UserData. 
     var thisUserData = new GVs.UserData($('#firstname').val(), $('#lastname').val(), $('#username').val(), $('#password').val(), $('#confirmpassword').val(), $('#phone').val(), $('#email').val()); 
     //POST call; Sends thisUserData and alerts that a user was updated. 
     $.post('/user/edit', {userFormData: thisUserData}, function(data){ 
      alert("User updated!"); 
     }); 
     }); 
    }); 

我，当我打电话GVS var thisUserData = new GVs.UserData(...);

我也试图通过它上得到一个错误与“数据”相同的方式，但它做了同样的事情。

编辑：我想看看我是否能在玉文件中获取GVS像这样

p There will hopefully be a form to change users here. 

成为本

p There will hopefully be a form to change users here. '#{GVs.UserData}' 

和它的存在，我为什么能得到它在玉，但不在脚本中？

您需要在客户端JS和服务器端之间传递变量，因为客户端并不知道node.js全局变量。例如：

extends ../layout 

block content 
    h1 Edit - Change Your Profile 
    p There will hopefully be a form to change users here. 
    form(id='form',action='') 
    include ./includes/user-form.jade 
    input(type='reset', value='Clear') 
    input(type='submit', value='Update') 
    script. 
    var GVs = !{JSON.stringify(GVs)}; 
    //Wait for document to load. 
    $(document).ready(function(){ 
     $('#firstname').val('#{data.firstname}'); 
     $('#lastname').val('#{data.lastname}'); 
     $('#username').val('#{data.username}'); 
     $('#phone').val('#{data.phone}'); 
     $('#email').val('#{data.email}'); 

     //Once form is submitted thisUserData (UserData) is created. 
     $('#form').submit(function(){ 
     // creates the variable thisUserData as a new UserData. 
     var thisUserData = new GVs.UserData($('#firstname').val(), $('#lastname').val(), $('#username').val(), $('#password').val(), $('#confirmpassword').val(), $('#phone').val(), $('#email').val()); 
     //POST call; Sends thisUserData and alerts that a user was updated. 
     $.post('/user/edit', {userFormData: thisUserData}, function(data){ 
      alert("User updated!"); 
     }); 
     }); 
    });
