Pug-Jade模板访问模块数据

Question

Edit : I'm trying to create a pug-jade template in which a table is created, the first row of the table is static (ie some headers ) for each subsequent row i want to add an employee. I have 3 files express.js (handels request to my app) employee.js, and index.pug.
Here is what i export in employee.js

function Employee (id,name,surname,lvl,salary){
this.id = id;
this.name = name;}
exports.employees = {
employeeList: [],
//the empList is a list of employee defined above, class contains some other methods   
}  

In the express.js i call :

var employees = require('./employees')

inside the request handler i call :

res.render('index',{employees: employees})

and finally in index.pug i try to :

tbody
    for val in employees.employeeList
        td=val.id
        td=val.name   

And this is the error :

TypeError: /Users/filippobosco/Desktop/GitHubRepos/IngSoftware2/Employees/ExpressTutorial/views/index.pug:39   

  37| th Salary
  38| tbody
> 39| for val in employees.employeeList
  40| td=val.id
  41| td=val.name
  42| 

  Cannot read property 'length' of undefined

I hope it is more clear now.

Answer 1

Your employees variable is undefined .

This means that there is a problem with your require('employees') import. Without being able to see the employees.js files, I'd have to guess that you're exports are not set up correctly.

Answer 2

Once you've dealt with the suggestions above...

I came here from having a similar issue and what worked for me would have been something like this:

tbody
for val in employees.employeeList
    td #{val.id}
    td #{val.name}  

NOTE: I am using pug 3.10.6
