node.js - express-validator retain input values -

Im node nodes, expressjs and z I am using express-validator to validate a form.

In the route:

  req.assert ('firstname', 'name is required') notEmpty () .; Req.assert ('Last name', 'name is required'). NotEmpty (); Req.assert ('email', 'a valid email is required'). IsEmail (); Var Errors = req.validationErrors (); .... if (errors) {res.render ('user / new', {errors: errors}); }   
 in  Z , to display the error:  
  - if (errors) div.alert .alert-ral ul - errors in every error li = error.msg   
 The above code works I want to keep the input value in the form so that users do not type it.  
  input # name (type = "text", name = "name", value = "?")   
 how?  
 Thanks   
 
 
 You can revert the value to the rendered view directly and Input tags can be placed on each other.  
  if (errors) {res.render ('users / new', {errors: errors, first name first name, ...}); }   
 and put in jade template  
  input # name (type = "text", name = "firstname", value = "# {firstName} Input # name (type = "text", name = "firstname", value = first name)   
 or

 It depends on your personal style. It is better to define values ​​like  
  person.first ,  person.last  and  Person.email , because you only You can put  person  in the view of your code.
